Further Consideration of Subtypes of Alzheimer's Disease
There has been some thought given to whether Alzheimer's disease is a collection of fairly distinct subtypes, with different origins and different dominant processes of pathology. The evidence for subtypes of Alzheimer's disease is suggestive, as noted in this article. It remains to be seen as to what the research community will do with all of this data, but it is possible that some therapies are not as bad as originally thought, if analysis were restricted to only one subtype of Alzheimer's disease. Proteins floating in the cerebrospinal fluid (CSF) might do more than diagnose Alzheimer's disease (AD) - they may ...

In conclusion, a number of studies have shown that CD4+ Treg cells are crucial in the maintenance of peripheral tolerance and have an important role in the control of atherosclerosis-related inflammation. Therefore, Treg cells are a promising target of major research efforts focused on immune-modulating therapies against atherosclerosis. Developing anti-atherosclerotic Treg-based therapies faces challenges. However, rapid progress in genetic, epigenetic, and molecular aspects of cellular immunology gives hope for a fast-track solution. « Back to Top Delivering Senolytic Nanoparticles to Atheroscle...

Towards More Selective Ways to Block Unwanted Inflammation
Control of chronic inflammation may turn out to be one of the more important themes in the treatment of aging as a medical condition. Senescent cells generate inflammatory signaling, but removing that contribution is likely the easiest aspect of the problem. Many forms of age-related cellular damage and dysfunction generate constant, unwanted, excess inflammation through interactions and signals that are used during a normal, desirable inflammatory reaction, such as to injury or infection. Thus interfering in these mechanisms must be very selective; simply blockading a given signal has undesirable side-effects, such as a w...

T Cell Dysfunction in Neurodegenerative Conditions
Chronic inflammation and dysfunction of immune cells is a characteristic of neurodegenerative conditions. Attention is usually given to the innate immune cells of the central nervous system in this context, but it is also the case that the adaptive immune system outside the brain tends towards dysfunction in older individuals suffering from age-related disease. Researchers here review what is known of T cell exhaustion, senescence, and other issues in older individuals. It is hoped that clearing these problematic cells from the immune population, such as via the use of senolytic drugs to destroy senescent cells, will have ...

In this study, we tested the hypothesis that periodontal disease (PD) as a source of infection alters inflammatory activation and Aβ phagocytosis by the microglial cells. Experimental PD was induced using ligatures in C57BL/6 mice for 1, 10, 20, and 30 days to assess the progression of PD. Animals without ligatures were used as controls. Ligature placement caused progressive periodontal disease and bone resorption that was already significant on day 1 post-ligation and continued to increase until day 30. The severity of periodontal disease increased the frequency of activated microglia in the brains on day 30 by 36...

From medical student to MS warrior: Navigating life with multiple sclerosis
I was diagnosed with multiple sclerosis during my second year of medical school. It happened while I was on a neurology rotation when I approached the neurologist after a lecture and expressed my suspicion of a flare-up. Subsequently, a lumbar puncture and a contrast brain MRI confirmed the diagnosis, leading to my treatment with IV Read more… From medical student to MS warrior: Navigating life with multiple sclerosis originally appeared in KevinMD.com.

Reviewing What is Known of the Biochemistry of Klotho Relevant to Effects on Life Span
Increased klotho expression increases longevity in mice, while reduced klotho expression accelerates aging. The most well studied effects of klotho on organ function involve the kidney and brain, where in both cases it appears protective via a number of different mechanisms. Unfortunately, klotho expression declines with age. Whether treating humans with therapies that increase levels of klotho will produce effects that are as large as those observed in mice remains to be seen. Programs that might lead to treatments remain at a preclinical stage of development, though recently advanced to the point of testing in non-human ...

Building a Digital Immune System
Credit: Courtesy of Dr. Tomas Helikar. The power of computer code has been a longtime fascination for Tomas Helikar, Ph.D., a professor of biochemistry at the University of Nebraska-Lincoln (UNL). In college, when he learned he could use that power to help researchers better understand biology and improve human health, Dr. Helikar knew he’d found his ideal career. Since then, he’s built a successful team of scientists studying the ways we can use mathematical models in biomedical research, such as creating a digital replica of the immune system that could predict how a patient will react to infectious microorganisms ...

This study explored the association between different cooking fuel types and the risk of cancer and all-cause mortality among seniors constructing Cox regression models. Data were obtained by linking waves of 6, 7, and 8 of the Chinese Longitudinal Healthy Longevity Survey, which included a total of 7,269 participants who were 65 years old and over. Cooking fuels were categorized as either biomass, fossil, or clean fuels. And the effects of switching cooking fuels on death risk were also investigated using Cox regression models. The results indicate that, compared with the users of clean fuels, individuals using bio...

Towards Treatments for Neurodegenerative Disease via Alteration of the Gut Microbiome
The balance of microbial populations making up the gut microbiome shifts with age, favoring potentially harmful, inflammatory microbes over those that produce beneficial metabolites. This is increasingly associated with the development of disease, and particularly with neurodegenerative conditions, though every age-related condition with a strong inflammatory component to its pathology is likely accelerated by the aging of the gut microbiome. There are ways to adjust the balance of populations to restore a more youthful configuration, such as fecal microbiota transplantation from a young donor, but the research community h...

Will Success in Reversing Aging Shape the Regulatory System to Accommodate It?
A sizable fraction of the therapies produced by the medical industry are, not to put too fine a point on it, garbage. The benefit is not worth the cost of diverting the resources into the full scale production of the drug, versus those resources going towards some better form of medical research and development. Giving a cancer patient an extra month or two of life, reducing fibrosis in the liver by 10% over a year of treatment, incrementally improving mitophagy to half the degree that exercise achieves, and so forth. Small molecule development in particular excels at producing this sort out outcome, as the effects on gene...
