Heat Shock Proteins as a Basis for Tackling Protein Aggregation in Neurodegenerative Diseases
Neurodegenerative conditions are largely characterized by the aggregation of a few altered proteins that are prone to forming solid deposits in and around neurons. Tissues, such as the brain, made up of long-lived cells, such as neurons, are particularly vulnerable to this sort of dysfunction, as they cannot dilute harmful protein aggregates by cell division, and dysfunctional cells are not readily destroyed and replaced. Cells must rely upon internal quality control mechanisms such as the presence of chaperone proteins responsible for chasing down misfolded or otherwise problematic proteins, and ensuring they are refolded...

New Fluorescent Tags Developed to Track Cause of Alzheimer ’s
Amyloid protein plaques, particularly ones made of beta-amyloid 42, are a prime suspect in the development of Alzheimer’s disease. Soluble oligomers, in this case molecules with a few repeating peptide units, may turn out to be the main culprit. They’re known to be toxic to neurons and some recent studies have led researchers to focus more attention on them. To better understand the root causes of Alzheimer’s, researchers need a way to track oligomers in the lab, but Thioflavin T dyes that lab techs use to flag amyloid fibrils don’t work well with oligomers. To overcome this serious limitation, c...

Fight Aging! Newsletter, August 19th 2019
In conclusion, our data show how oncogenic and tumor-suppressive drivers of cellular senescence act to regulate surveillance processes that can be circumvented to enable SnCs to elude immune recognition but can be reversed by cell surface-targeted interventions to purge the SnCs that persist in vitro and in patients. Since eliminating SnCs can prevent tumor progression, delay the onset of degenerative diseases, and restore fitness; since NKG2D-Ls are not widely expressed in healthy human tissues and NKG2D-L shedding is an evasion mechanism also employed by tumor cells; and since increasing numbers of B cells express NKG2D ...

Cellular Maintenance Mechanisms Struggle to Break Down TDP-43 Aggregates, Leading to Neurodegeneration
The most common age-related neurodegenerative conditions are associated with the build up of various protein aggregates, chemically altered or misfolded proteins that can form solid deposits in and around cells when in that state. These protein aggregates are characterized by the ability to spread and grow, acting as seeds for more aggregation. They include the well known amyloid-β and tau of Alzheimer's disease, the α-synuclein associated with Parkinson's disease, and so forth. In recent years researchers have been devoting ever more effort to investigations of a less well known protein aggregate, TDP-43, assoc...

In this study, we report the age-associated differences between fetal MSC (fMSC) populations and MSCs isolated from elderly donors with respect to their transcriptomes. We successfully reprogrammed fMSCs (55 days post conception) and adult MSC (aMSC; 60-74 years) to iPSCs and, subsequently, generated the corresponding iMSCs. In addition, iMSCs were also derived from ESCs. The iMSCs were similar although not identical to primary MSCs. We unraveled a putative rejuvenation and aging gene expression signature. We show that iMSCs irrespective of donor age and cell type re-acquired a similar secretome to that of th...

Tackling Amyloid- β Oligomers by Interfering in Specific Interactions Necessary to Protein Aggregation
The present consensus on the the development of Alzheimer's disease is that it starts with the accumulation of amyloid-β, though there are many competing theories as to why only some people exhibit this problem to a great enough degree to produce pathology. The biochemistry of oligomers supporting amyloid-β causes sufficient disarray in brain metabolism to set the stage for neuroinflammation, malfunction of immune cells in the brain, and aggregation of altered forms of tau protein into neurofibrillary tangles that cause most of the damage and cell death in the later stages of the condition. The failure to improve...

Amyloid- β May Cause Mitochondrial Dysfunction in Alzheimer's Disease
This study reinforces the toxicity of oligomeric amyloid-β on neuronal mitochondria and stresses the importance for protective compounds to protect the mitochondria from oligomeric amyloid-β toxicity." In the new study, cells known as pyramidal neurons, extracted from the hippocampus of patients who died of Alzheimer's, display a marked reduction in the expression of a suite of mitochondrial genes, pointing to their degradation by OAβ. The reduction of mitochondrial gene expression was also seen when cells belonging to a human neuroblastoma cell line were exposed to OAβ. The authors stress t...

Orphan Diseases Or Population Health? Policy Choices Drive Venture Capital Investments
The US exhibits a remarkable pipeline of biopharmaceutical innovation, with 170 new drugs and biologics launched into the market between 2011 and 2015 and another 22 drugs approved in 2016. A striking feature of the pharmaceutical pipeline is the large percentage launched for the treatment of small “orphan” indications, defined by the Food and Drug Administration (FDA) as including fewer than, often many fewer than, 200,000 patients in the United States. Almost half (74) of the products approved by the FDA between 2011 and 2015 were for orphan indications, twice the number (36) approved during the same period b...

A Demonstration in Mice of Whole Mitochondria Delivered as a Therapy
Mitochondria, the swarming power plants of the cell, become damaged and dysfunctional with age. Can this be addressed by delivering complete, whole, new mitochondria as a therapy? There have been signs in past years that cells can ingest and incorporate mitochondria from the surrounding environment, but few useful demonstrations to show whether or not this is common in living tissues. In the research here, researchers achieve that result, delivering mitochondria into tissues as a therapy, and using this approach to treat an animal model of Parkinson's disease. This neurodegenerative condition is associated with degraded mi...

MR-HIFU and ThermoDox to Treat Recurrent Childhood Tumors: Interview with AeRang Kim, Principal Investigator
Children’s National Health System and the Celsion Corporation (Lawrenceville, NJ) have recently announced a Phase I clinical trial in the US to determine a safe and tolerable dose of ThermoDox in conjunction with non-invasive magnetic resonance-guided high-intensity focused ultrasound (MR-HIFU). The trial is aimed on young adults and children with recurring solid tumors. ThermoDox technology consists of liposomes loaded with doxorubicin, a conventional chemotherapeutic drug. Liposomes are small lipid structures which can be used to encapsulate and deliver drugs through the bloodstream. While liposomal doxor...

Are Priority Review Vouchers The Answer To Incentivize Drug Development? Not So Fast.
In the May issue of Health Affairs, two papers examine the potential for voucher systems to incentivize drug development in areas of unmet medical need. Co-authors Kevin Outterson and Anthony McDonnell take a look at potential exclusivity voucher programs designed to encourage development of new antibiotics, while David Ridley and Stephane Régnier analyze the effects that expansion of existing priority review voucher (PRV) programs may have on the value of PRVs as a development incentive. Ridley and Régnier’s work is of particular importance as both houses of Congress pursue a spate of legislative propo...

Pediatric palliative care: We must do more
How is it that, in this day and age, a talented teenager treated for lymphoma emerges cured but with a life-threatening eating disorder? How is it that, in our nation’s capital, a boy dying at home from neuroblastoma experiences excruciating pain in his final moments? How is that, when we develop new drugs to treat children with cancer, we do not, at the same time, routinely and in a standardized manner ask them how they are feeling? As a pediatric oncologist and palliative care physician, I was alarmed by stories like these at the recent Institute of Medicine Workshop on Comprehensive Care f...

The Future of Cord Blood Research
You may have heard that the stem cells in your baby’s umbilical-cord blood can save lives, but if you’re like most people, you have only a vague notion of how stem cells work — or which diseases they can treat. Right now, certain cancers, blood disorders, and immune disorders, among other conditions, are being successfully treated with cord-blood stem cells — and thanks to cord blood research, the list of conditions and diseases that may be treated by these stem cells is growing. Why is it important to know about the cord blood research and what types of diseases it can treat? Knowing what co...
