Stem-Cell Based Therapy for Alzheimer’s Disease



Advancing Research into Alzheimer’s Disease with Stem Cells

 

Disease Burden of Alzheimer’s

Alzheimer’s disease (AD) is the most common cause of dementia, a progressively debilitating neurodegenerative disease that results in declining cognitive functions, inability to form new memories, behavioral disorders, and gradual loss of bodily functions. While older age does not cause AD, the risk of AD doubles about every five years beyond age 651. The World Health Organization estimates that about 50 million people living with dementia globally. In 2050, the number is expected to increase to 152 million2. In the U.S., a total of 122,019 recorded deaths were due to AD (2018), making it the 6th leading cause of death among adults in the country3. Hence, AD has a significant disease burden worldwide. Currently, the economic burden of AD is estimated to be $305 billion4. To date, there is no cure for dementia or AD.

 

Neuropathological Features and Causes of Alzheimer’s Disease

One of the key neuropathological features of AD is the presence of brain lesions consisting of amyloid plaques. It is caused by the pathological extracellular accumulation and deposition of amyloid-beta peptide (amyloid-beta)5. Although the exact function of amyloid-beta is largely unclear, there have been some speculations regarding its physiological roles in the body6. Regardless, targeting amyloid-beta production and accumulation remains to be an attractive therapeutic solution to treat AD7,8. Other hallmarks of AD include the presence of neurofibrillary tangles and hyperphosphorylated tau in brain tissues.

AD is a complex, multifactorial disease caused by a mix of genetic and environmental factors9. It can be broadly classified into two types – sporadic (SAD) and familial (FAD) AD. SAD and FAD are typically late-onset and early-onset respectively
10. FAD is rare and is caused by genetic mutations (such as in the Amyloid Precursor Protein [APP] gene); environmental factors play small roles in contributing to the disease. On the other hand, several genes are associated with SAD but environmental factors are also observed to contribute to the disease

Lack of Suitable Platforms to Study AD

Over the past decade, researchers have adopted different systems to study AD. Post-mortem brain tissue samples from individuals with AD have been crucial in identifying and better understanding the physical and molecular changes of the brain caused by the disease. Cultured human and mouse cells have also been useful in understanding amyloid-beta accumulation and plaque formation but these cells are usually transformed to allow cells to remain proliferative; therefore they are not physiologically relevant and are unsuitable to study age-related aspects of AD. Also, it is difficult to grow and culture human neurons in the lab. Therefore, researchers looked to using transgenic mice to model AD. There have been some successes in generating FAD mice by overexpressing APP11. These mice were able to show age-related formation of amyloid-beta plaques, learning problems, and neuronal synapse loss. Today, there are more mice models that mimic various AD pathologies11. However, these mice are still unable to reflect the full complexity of the neurodegeneration process associated with AD12. The unfortunate reality is exemplified by the fact that clinical trials for AD drug development have a failure rate of 99.6%13.

 

Making Diseased Neurons in the Lab to Better Understand Disease Pathogenesis

 

The discovery of the Nobel Prize-winning iPSC technology
14,15 has advanced AD research by miles. There are many successes in using iPSCs to model and study both SAD and FAD in the lab16,17. Researchers have generated stem cell-derived neurons, microglia, astrocytes, and even 3D brain organoids that exhibited disease phenotypes. Because iPSCs are self-renewal and highly proliferative, we now have unlimited resources to study the disease pathogenesis of AD18.  

Recently, a group of researchers from Harvard Medical School utilized the iPSC technology and reprogrammed skin cells from patients with SAD into iPSCs19. The patient-specific iPSCs were then differentiated into neural progenitor cells (NPCs) to obtain SAD NPCs. Using these diseased cells, they were able to uncover new information about the disease – diseased cells showed abnormal signs of accelerated maturation as compared to healthy cells. They were also discovered that the diseased cells have a loss of function of a protein called REST. By restoring levels of functional REST, they were able to prevent early maturation of SAD NPCs.

Another group of researchers from the Mayo Clinic differentiated AD iPSCs into cerebral organoids (‘mini-brains’), which are 3D self-organizing structures that recapitulate many features of the human brain. The diseased cerebral organoids showed high levels of amyloid-beta and phosphorylated tau, which are key features of AD. Using these diseased ‘mini-brains’, they were also able to uncover new knowledge about the disease which includes altered RNA metabolism and increased numbers of stress granules 20.

 

 

Stem-Cell Based Therapy for Alzheimer’s Disease

With the lack of suitable platforms to study AD as well as the gross limitations of current mice models of AD, researchers and the public alike have started to feel disheartened. However, in recent years, proof-of-concept studies of various types of stem cell-based therapies have shown great promise in treating AD.

Firstly, the use of Mesenchymal Stem Cells (MSCs) to treat AD is actively pursued right now. MSCs are stem cells that are found in umbilical cord blood, the Wharton jelly (a connective tissue found in the umbilical cord), bone marrow, and even fat tissues. In fact, a phase 1 clinical trial investigating the use of umbilical cord blood MSCs to treat AD patients was completed in 201521 and results showed that the treatment was both safe and feasible. MSCs can potentially treat AD via three ways – immune regulation, reducing numbers of amyloid-beta plaques, and promote neurotrophic regeneration and evidences suggest that the therapeutic potential of MSCs lies with the extracellular vesicles/ exosomes, produced by MSCs22. Exosomes contain nucleic acids, proteins, enzymes and even immune signals that are able to promote regeneration, regulation inflammation, and clear amyloid-beta plaques.

Next, the cellular transplantation of NPCs differentiated from embryonic stem cells (ESCs) was able to improve learning and memory functions in rat models of AD23. In addition, transplanting human induced-neural progenitor/ stem cells (iNPCs) into the hippocampus of AD mice restored cognitive deficits of diseased mice and significantly improved cognitive performance
24. Therefore, ESC-derived NPCs and iNPCs can potentially serve as therapeutic options to treat and improve cognitive functionalities of AD patients. Other than NPCs, stem cell-derived glial cells25 were also able to reduce amyloid-beta deposition and were effective in decreasing cognitive dysfunctions in AD mice.

The risk of graft rejection will be reduced if patient-specific iPSCs were used to generate cells for autologous transplantation. Genetic mutations found in the patients can also be edited via the CRISPR/Cas926 technology. This way, NPCs, neurons, or glial cells differentiated from patient-specific (edited) iPSCs will be healthy and will not be rejected by the patients’ immune system.

 

Concluding Comments

Over the past few years, research into AD has allowed us to better understand disease etiology and pathogenesis, but research efforts were hindered by the lack of suitable platforms to study the disease. Animal models of AD are still unable to fully reflect the complexities of the disease observed in humans. The advent of stem cell technologies has allowed us to model AD more accurately and sustainably. With that, stem cell-based therapies have also shown great successes in improving cognitive functions in animal models of AD. In the years to come, more studies would have to be done to determine the safety and efficacy of transplanting MSCs as well as ESC/iPSC-derived cells in treating AD patients.

Cocrystal’s Lead COVID-19 Antiviral CDI-45205 Shown to be Active Against SARS-CoV-2 and Two Prominent SARS-CoV-2 Variants


Cocrystal’s Lead COVID-19 Antiviral CDI-45205 Shown to be Active Against SARS-CoV-2 and Two Prominent SARS-CoV-2 Variants

 

BOTHELL, Wash., June 14, 2021 (GLOBE NEWSWIRE) — Cocrystal Pharma, Inc. (Nasdaq: COCP) (“Cocrystal” or the “Company”), a clinical-stage biotechnology company discovering and developing novel antiviral therapeutics that target the replication machinery of influenza viruses, coronaviruses, hepatitis C viruses and noroviruses, announces that its lead preclinical SARS-CoV-2 3CL protease inhibitor CDI-45205 is active against SARS-CoV-2 and two prominent SARS-CoV-2 variants.

A third-party laboratory contracted by Cocrystal conducted in vitro studies evaluating the antiviral activity of CDI-45205 and its analogs in VeroE6-eGFP cells infected with SARS-CoV-2 (Wuhan strain), the United Kingdom variant (B.1.1.7) and the South African variant (B.1.351). CDI-45205 and its analogs showed excellent antiviral activity against both SARS-CoV-2 variants, surpassing the activity observed with SARS-CoV-2 (Wuhan strain). Two reference inhibitors including remdesivir, an FDA-approved SARS-CoV-2 RNA-dependent RNA polymerase inhibitor, and PF-00835231, another SARS-CoV-2 3CL protease inhibitor, were included in the study as comparators. Results showed CDI-45205 had excellent antiviral activity against the United Kingdom variant, with an EC50 of 1.9 uM (remdesivir EC50 0.6 uM; PF-00835231 EC50 >100 uM) and against the South African variant, with an EC50 of 2.5 uM (remdesivir EC50 0.8 uM; PF-00835231 EC50 >100 uM) in the absence of a P-glycoprotein efflux inhibitor.

“We are highly encouraged by these results with CDI-45205 against SARS-CoV-2 and two prominent variants of SARS-CoV-2, and we intend to continue with further testing for antiviral activity against other emerging variants including the Indian variant,” said Sam Lee, Ph.D., Cocrystal’s President and interim co-CEO. “These findings add to the growing body of preclinical data of CDI-45205. We believe these new data suggest our protease inhibitor may be an effective treatment of COVID-19 caused by SARS-CoV-2 and its emerging variants. Additionally, Cocrystal scientists are currently using our proprietary structure-based drug discovery platform technology to investigate broad-spectrum oral protease inhibitors and replication inhibitors for the treatment of COVID-19.”

About CDI-45205
In December 2020 Cocrystal announced the selection of CDI-45205 as its lead coronavirus development candidate among a group of protease inhibitors obtained under an exclusive license agreement with Kansas State University Research Foundation (KSURF) announced earlier in 2020.

CDI-45205 showed good bioavailability in mouse and rat pharmacokinetic studies via intraperitoneal injection, and also no cytotoxicity against a variety of human cell lines. The Company recently demonstrated a strong synergistic effect with remdesivir. Additionally, a proof-of-concept animal study demonstrated that daily injection of CDI-45205 exhibited favorable in vivo efficacy in MERS-CoV-infected mice. Cocrystal has obtained promising preliminary pharmacokinetic results and is continuing to further evaluate CDI-45205.

Bunker Hill Achieves Key Milestone to Increase U.S. Trading Liquidity: Caveat Emptor Status Lifted, OTCQB Upgrade Underway


Bunker Hill Achieves Key Milestone to Increase U.S. Trading Liquidity: Caveat Emptor Status Lifted, OTCQB Upgrade Underway

 

Sam Ash, CEO and David Wiens, CFO to host Live Interactive Virtual Investor Event on
Wednesday, June 16 @ 11:00am ET / 8:00am PT. Investors are invited to register for this event at: LINK

TORONTO, June 14, 2021 (GLOBE NEWSWIRE) — Bunker Hill Mining Corp. (the “Company”) (CSE: BNKR, OTC: BHLL) is pleased to announce the achievement of a key milestone in its efforts to increase its U.S. trading liquidity: as of today, its listing on OTC Markets under symbol BHLL is no longer subject to ‘caveat emptor’ classification as a result of clearance by FINRA and OTC Markets, following extensive regulatory review. As a result, an active market now exists for the Company’s shares in the U.S., with bid and ask quotes permitted and available, and availability for U.S. trading without restrictions on a wide variety of brokerage platforms.

Prior to June 2021, and related to regulatory compliance issues in the 2011-2012 period under previous management, board and shareholders, the Company’s shares had traded in the ‘Grey Market’, where no bid or ask quotes are available, and trading is restricted on many brokerage platforms. See the ‘Background’ section below for more detail. This had effectively resulted in the inability of the vast majority of investors to trade the Company’s shares in the U.S. for the last nine years, which the Company believes has been a primary contributor to its low level of trading liquidity.

As a logical next step, the Company has submitted an application for an upgrade to the OTCQB, which it believes will further increase U.S. trading liquidity and benefit investors.

Sam Ash CEO stated, “We are delighted to achieve this key milestone, which not only immediately improves market trading access for our investors, but directly addresses concerns expressed by existing and potential new investors regarding historic issues that preceded the current management and Board. We look forward to working with OTC Markets over the coming weeks on our OTCQB application, as the next step in continuing to mature the company.”

BACKGROUND

In March 2021, the Company engaged B. Riley, a leading U.S. brokerage firm, as its exclusive capital markets advisor with respect to its U.S. share listing under symbol BHLL on OTC Markets. After a period of comprehensive due diligence which included an examination of the Company’s public filings, governance, shareholder register, and all legal and other documentation pertaining to its ‘caveat emptor’ status, B. Riley filed a Form 211 with FINRA in which it proposed to act as a market maker for the Company’s shares in the U.S. and attested to its belief that the Company’s U.S. listing was in full compliance with requirements prescribed by FINRA. On May 26, 2021, following extensive review, the Form 211 was cleared.

Clearance of the Form 211 by FINRA was a pre-condition to an application with OTC Markets for the removal of the Company’s ‘caveat emptor’ status. As such, the Company submitted an application to OTC Markets at the end of May 2021. The Company received formal notice of the approval of its application on June 11, 2021.

The Company’s former trading in the ‘Grey Market’ and ‘caveat emptor’ status related to an SEC investigation of a former significant shareholder of Liberty Silver Corp. in the 2011-2012 period, due to an alleged breach of U.S. securities laws. Liberty Silver Corp. changed its name to Bunker Hill Mining Corp. in 2017. The Company’s current leadership team was appointed in March 2020 and thereafter.

The NFL and Big Companies are Changing Their Thinking on Marijuana



The NFL is Providing Funds for a Marijuana Study Related to Injured Athlete Use

The National Football League’s (NFL) Pain Management Committee along with the NFL Players Association announced they’d be providing $1 million to help fund research of cannabinoids for pain management, last week.

This step represents further movement in the NFL’s stance toward exploring the use of marijuana products by professional football players. According to the NFL website, some players have maintained that it is safer for them to use marijuana to treat pain than to take prescription medication.

 

Pivot on Thinking

In the past, the NFL would suspend players if they tested positive for using cannabis products multiple times. Last year’s collective bargaining agreement between the league and the players union ended this policy. Now the NFL is determined to learn more about how safe marijuana and CBD are and whether they provide pain relief, especially if they can be a potential alternative to opioids.

The league expects to fund up to five grants to winners of an RFP process.  Dr. Kevin Hill, who is the co-chair of the NFL’s Pain Management Committee, and Director of Addiction Psychiatry at Beth Israel Deaconess Medical Center is also the author of Marijuana: The Unbiased Truth about the World’s Most Popular Weed. Hill wants to be cautious.  According to the NFL, he believes that right now, the level of interest in the use of medical marijuana far exceeds the level of evidence available.

Dr. Hill said that the committee had heard mixed results from players about using marijuana to treat pain. Hill said that there is some indication that using medical marijuana and CBD to treat pain may be riskier than most people realize and that the doses necessary to address pain may create risk for liver toxicity and interactions with other medications.

Dr. Allen Sills, the NFL’s Chief Medical Officer, said “There is a need for better information, better science,” Sills wants it clear that using cannabis and CBD to treat pain impact performance in elite athletes is beneficial. The goal of funding this research is to provide more informed guidance before allowing or disallowing any particular treatment related to CBD or other cannabinoids.

 

Take-Away

The NFL announcement to provide funding for studies into the true impact, benefits, and drawbacks of cannabis use by its players is a high-profile announcement within the cannabis industry. Regardless of the outcome of the studies, the NFL’s interest is a noticeable pivot in direction and can be perceived as a nod to the legitimacy of cannabis products for pain management.

In a related announcement this month, Amazon stated they will no longer test most job applicants for marijuana use. This growing trend toward legitimizing the once-taboo plant bodes well for cannabis companies in their uphill climb toward a more widespread embrace of their products.

Release – Cocrystals Lead COVID-19 Antiviral CDI-45205 Shown to be Active Against SARS-CoV-2 and Two Prominent SARS-CoV-2 Variants


Cocrystal’s Lead COVID-19 Antiviral CDI-45205 Shown to be Active Against SARS-CoV-2 and Two Prominent SARS-CoV-2 Variants

 

BOTHELL, Wash., June 14, 2021 (GLOBE NEWSWIRE) — Cocrystal Pharma, Inc. (Nasdaq: COCP) (“Cocrystal” or the “Company”), a clinical-stage biotechnology company discovering and developing novel antiviral therapeutics that target the replication machinery of influenza viruses, coronaviruses, hepatitis C viruses and noroviruses, announces that its lead preclinical SARS-CoV-2 3CL protease inhibitor CDI-45205 is active against SARS-CoV-2 and two prominent SARS-CoV-2 variants.

A third-party laboratory contracted by Cocrystal conducted in vitro studies evaluating the antiviral activity of CDI-45205 and its analogs in VeroE6-eGFP cells infected with SARS-CoV-2 (Wuhan strain), the United Kingdom variant (B.1.1.7) and the South African variant (B.1.351). CDI-45205 and its analogs showed excellent antiviral activity against both SARS-CoV-2 variants, surpassing the activity observed with SARS-CoV-2 (Wuhan strain). Two reference inhibitors including remdesivir, an FDA-approved SARS-CoV-2 RNA-dependent RNA polymerase inhibitor, and PF-00835231, another SARS-CoV-2 3CL protease inhibitor, were included in the study as comparators. Results showed CDI-45205 had excellent antiviral activity against the United Kingdom variant, with an EC50 of 1.9 uM (remdesivir EC50 0.6 uM; PF-00835231 EC50 >100 uM) and against the South African variant, with an EC50 of 2.5 uM (remdesivir EC50 0.8 uM; PF-00835231 EC50 >100 uM) in the absence of a P-glycoprotein efflux inhibitor.

“We are highly encouraged by these results with CDI-45205 against SARS-CoV-2 and two prominent variants of SARS-CoV-2, and we intend to continue with further testing for antiviral activity against other emerging variants including the Indian variant,” said Sam Lee, Ph.D., Cocrystal’s President and interim co-CEO. “These findings add to the growing body of preclinical data of CDI-45205. We believe these new data suggest our protease inhibitor may be an effective treatment of COVID-19 caused by SARS-CoV-2 and its emerging variants. Additionally, Cocrystal scientists are currently using our proprietary structure-based drug discovery platform technology to investigate broad-spectrum oral protease inhibitors and replication inhibitors for the treatment of COVID-19.”

About CDI-45205
In December 2020 Cocrystal announced the selection of CDI-45205 as its lead coronavirus development candidate among a group of protease inhibitors obtained under an exclusive license agreement with Kansas State University Research Foundation (KSURF) announced earlier in 2020.

CDI-45205 showed good bioavailability in mouse and rat pharmacokinetic studies via intraperitoneal injection, and also no cytotoxicity against a variety of human cell lines. The Company recently demonstrated a strong synergistic effect with remdesivir. Additionally, a proof-of-concept animal study demonstrated that daily injection of CDI-45205 exhibited favorable in vivo efficacy in MERS-CoV-infected mice. Cocrystal has obtained promising preliminary pharmacokinetic results and is continuing to further evaluate CDI-45205.

About Cocrystal Pharma, Inc.
Cocrystal Pharma, Inc. is a clinical-stage biotechnology company discovering and developing novel antiviral therapeutics that target the replication process of coronaviruses (including SARS-CoV-2), influenza viruses, hepatitis C viruses and noroviruses. Cocrystal employs unique structure-based technologies and Nobel Prize-winning expertise to create first- and best-in-class antiviral drugs.

Release – Bunker Hill Achieves Key Milestone to Increase U.S. Trading Liquidity


Bunker Hill Achieves Key Milestone to Increase U.S. Trading Liquidity: Caveat Emptor Status Lifted, OTCQB Upgrade Underway

 

Sam Ash, CEO and David Wiens, CFO to host Live Interactive Virtual Investor Event on
Wednesday, June 16 @ 11:00am ET / 8:00am PT. Investors are invited to register for this event at: LINK

TORONTO, June 14, 2021 (GLOBE NEWSWIRE) — Bunker Hill Mining Corp. (the “Company”) (CSE: BNKR, OTC: BHLL) is pleased to announce the achievement of a key milestone in its efforts to increase its U.S. trading liquidity: as of today, its listing on OTC Markets under symbol BHLL is no longer subject to ‘caveat emptor’ classification as a result of clearance by FINRA and OTC Markets, following extensive regulatory review. As a result, an active market now exists for the Company’s shares in the U.S., with bid and ask quotes permitted and available, and availability for U.S. trading without restrictions on a wide variety of brokerage platforms.

Prior to June 2021, and related to regulatory compliance issues in the 2011-2012 period under previous management, board and shareholders, the Company’s shares had traded in the ‘Grey Market’, where no bid or ask quotes are available, and trading is restricted on many brokerage platforms. See the ‘Background’ section below for more detail. This had effectively resulted in the inability of the vast majority of investors to trade the Company’s shares in the U.S. for the last nine years, which the Company believes has been a primary contributor to its low level of trading liquidity.

As a logical next step, the Company has submitted an application for an upgrade to the OTCQB, which it believes will further increase U.S. trading liquidity and benefit investors.

Sam Ash CEO stated, “We are delighted to achieve this key milestone, which not only immediately improves market trading access for our investors, but directly addresses concerns expressed by existing and potential new investors regarding historic issues that preceded the current management and Board. We look forward to working with OTC Markets over the coming weeks on our OTCQB application, as the next step in continuing to mature the company.”

BACKGROUND

In March 2021, the Company engaged B. Riley, a leading U.S. brokerage firm, as its exclusive capital markets advisor with respect to its U.S. share listing under symbol BHLL on OTC Markets. After a period of comprehensive due diligence which included an examination of the Company’s public filings, governance, shareholder register, and all legal and other documentation pertaining to its ‘caveat emptor’ status, B. Riley filed a Form 211 with FINRA in which it proposed to act as a market maker for the Company’s shares in the U.S. and attested to its belief that the Company’s U.S. listing was in full compliance with requirements prescribed by FINRA. On May 26, 2021, following extensive review, the Form 211 was cleared.

Clearance of the Form 211 by FINRA was a pre-condition to an application with OTC Markets for the removal of the Company’s ‘caveat emptor’ status. As such, the Company submitted an application to OTC Markets at the end of May 2021. The Company received formal notice of the approval of its application on June 11, 2021.

The Company’s former trading in the ‘Grey Market’ and ‘caveat emptor’ status related to an SEC investigation of a former significant shareholder of Liberty Silver Corp. in the 2011-2012 period, due to an alleged breach of U.S. securities laws. Liberty Silver Corp. changed its name to Bunker Hill Mining Corp. in 2017. The Company’s current leadership team was appointed in March 2020 and thereafter.

Stem-Cell Based Therapy for Alzheimers Disease



Advancing Research into Alzheimer’s Disease with Stem Cells

 

Disease Burden of Alzheimer’s

Alzheimer’s disease (AD) is the most common cause of dementia, a progressively debilitating neurodegenerative disease that results in declining cognitive functions, inability to form new memories, behavioral disorders, and gradual loss of bodily functions. While older age does not cause AD, the risk of AD doubles about every five years beyond age 651. The World Health Organization estimates that about 50 million people living with dementia globally. In 2050, the number is expected to increase to 152 million2. In the U.S., a total of 122,019 recorded deaths were due to AD (2018), making it the 6th leading cause of death among adults in the country3. Hence, AD has a significant disease burden worldwide. Currently, the economic burden of AD is estimated to be $305 billion4. To date, there is no cure for dementia or AD.

 

Neuropathological Features and Causes of Alzheimer’s Disease

One of the key neuropathological features of AD is the presence of brain lesions consisting of amyloid plaques. It is caused by the pathological extracellular accumulation and deposition of amyloid-beta peptide (amyloid-beta)5. Although the exact function of amyloid-beta is largely unclear, there have been some speculations regarding its physiological roles in the body6. Regardless, targeting amyloid-beta production and accumulation remains to be an attractive therapeutic solution to treat AD7,8. Other hallmarks of AD include the presence of neurofibrillary tangles and hyperphosphorylated tau in brain tissues.

AD is a complex, multifactorial disease caused by a mix of genetic and environmental factors9. It can be broadly classified into two types – sporadic (SAD) and familial (FAD) AD. SAD and FAD are typically late-onset and early-onset respectively
10. FAD is rare and is caused by genetic mutations (such as in the Amyloid Precursor Protein [APP] gene); environmental factors play small roles in contributing to the disease. On the other hand, several genes are associated with SAD but environmental factors are also observed to contribute to the disease
9

 

Lack of Suitable Platforms to Study AD

Over the past decade, researchers have adopted different systems to study AD. Post-mortem brain tissue samples from individuals with AD have been crucial in identifying and better understanding the physical and molecular changes of the brain caused by the disease. Cultured human and mouse cells have also been useful in understanding amyloid-beta accumulation and plaque formation but these cells are usually transformed to allow cells to remain proliferative; therefore they are not physiologically relevant and are unsuitable to study age-related aspects of AD. Also, it is difficult to grow and culture human neurons in the lab. Therefore, researchers looked to using transgenic mice to model AD. There have been some successes in generating FAD mice by overexpressing APP11. These mice were able to show age-related formation of amyloid-beta plaques, learning problems, and neuronal synapse loss. Today, there are more mice models that mimic various AD pathologies11. However, these mice are still unable to reflect the full complexity of the neurodegeneration process associated with AD12. The unfortunate reality is exemplified by the fact that clinical trials for AD drug development have a failure rate of 99.6%13.

 

Making Diseased Neurons in the Lab to Better Understand Disease Pathogenesis

 

The discovery of the Nobel Prize-winning iPSC technology
14,15 has advanced AD research by miles. There are many successes in using iPSCs to model and study both SAD and FAD in the lab16,17. Researchers have generated stem cell-derived neurons, microglia, astrocytes, and even 3D brain organoids that exhibited disease phenotypes. Because iPSCs are self-renewal and highly proliferative, we now have unlimited resources to study the disease pathogenesis of AD18.  

Recently, a group of researchers from Harvard Medical School utilized the iPSC technology and reprogrammed skin cells from patients with SAD into iPSCs19. The patient-specific iPSCs were then differentiated into neural progenitor cells (NPCs) to obtain SAD NPCs. Using these diseased cells, they were able to uncover new information about the disease – diseased cells showed abnormal signs of accelerated maturation as compared to healthy cells. They were also discovered that the diseased cells have a loss of function of a protein called REST. By restoring levels of functional REST, they were able to prevent early maturation of SAD NPCs.

Another group of researchers from the Mayo Clinic differentiated AD iPSCs into cerebral organoids (‘mini-brains’), which are 3D self-organizing structures that recapitulate many features of the human brain. The diseased cerebral organoids showed high levels of amyloid-beta and phosphorylated tau, which are key features of AD. Using these diseased ‘mini-brains’, they were also able to uncover new knowledge about the disease which includes altered RNA metabolism and increased numbers of stress granules 20.

 

 

Stem-Cell Based Therapy for Alzheimer’s Disease

With the lack of suitable platforms to study AD as well as the gross limitations of current mice models of AD, researchers and the public alike have started to feel disheartened. However, in recent years, proof-of-concept studies of various types of stem cell-based therapies have shown great promise in treating AD.

Firstly, the use of Mesenchymal Stem Cells (MSCs) to treat AD is actively pursued right now. MSCs are stem cells that are found in umbilical cord blood, the Wharton jelly (a connective tissue found in the umbilical cord), bone marrow, and even fat tissues. In fact, a phase 1 clinical trial investigating the use of umbilical cord blood MSCs to treat AD patients was completed in 201521 and results showed that the treatment was both safe and feasible. MSCs can potentially treat AD via three ways – immune regulation, reducing numbers of amyloid-beta plaques, and promote neurotrophic regeneration and evidences suggest that the therapeutic potential of MSCs lies with the extracellular vesicles/ exosomes, produced by MSCs22. Exosomes contain nucleic acids, proteins, enzymes and even immune signals that are able to promote regeneration, regulation inflammation, and clear amyloid-beta plaques.

Next, the cellular transplantation of NPCs differentiated from embryonic stem cells (ESCs) was able to improve learning and memory functions in rat models of AD23. In addition, transplanting human induced-neural progenitor/ stem cells (iNPCs) into the hippocampus of AD mice restored cognitive deficits of diseased mice and significantly improved cognitive performance
24. Therefore, ESC-derived NPCs and iNPCs can potentially serve as therapeutic options to treat and improve cognitive functionalities of AD patients. Other than NPCs, stem cell-derived glial cells25 were also able to reduce amyloid-beta deposition and were effective in decreasing cognitive dysfunctions in AD mice.

The risk of graft rejection will be reduced if patient-specific iPSCs were used to generate cells for autologous transplantation. Genetic mutations found in the patients can also be edited via the CRISPR/Cas926 technology. This way, NPCs, neurons, or glial cells differentiated from patient-specific (edited) iPSCs will be healthy and will not be rejected by the patients’ immune system.

 

Concluding Comments

Over the past few years, research into AD has allowed us to better understand disease etiology and pathogenesis, but research efforts were hindered by the lack of suitable platforms to study the disease. Animal models of AD are still unable to fully reflect the complexities of the disease observed in humans. The advent of stem cell technologies has allowed us to model AD more accurately and sustainably. With that, stem cell-based therapies have also shown great successes in improving cognitive functions in animal models of AD. In the years to come, more studies would have to be done to determine the safety and efficacy of transplanting MSCs as well as ESC/iPSC-derived cells in treating AD patients.
