Soluble Phosphorylated Tau as a Target in Alzheimer's Disease and other Tauopathies
The primary thrust of Alzheimer's research and clinical development of therapies remains the targeting of amyloid-β and tau aggregates. The failure to produce meaningful benefits in patients, even given reductions in amyloid-β and tau, is not shifting the focus of most research groups to other entirely different approaches, but rather to question whether the complexity of amyloid-β and tau biochemistry means that the wrong locations or types of these molecules were targeted by the immunotherapies used to date in human trials.
For optimal design of anti-amyloid-β (Aβ) and anti-tau clinical trials, we need to b...

In conclusion, the national prevalence of dementia and MCI in 2016 found in this cross-sectional study was similar to that of other US-based studies.
Clearing Microglia Reverses Age-Related Disruption of Sleeping Patterns in Mice

Microglia are innate immune cells of the central nervous system. They are analogous to macrophages in the rest of the body, but undertake additional duties relating to the function of neurons and in brain tissue. Microglia become overly active and inflamm...

What Has Omics Data Taught Us About Dementia?
An enormous amount of biological data can now be obtained from any given study population, and at reasonable cost. The resulting databases have grown to become very large. The epigenome, transcriptome, proteome, metabolome, microbiome, and much more, are at the fingertips of every epidemiological researcher, at multiple time points, before and after interventions, and at different ages. It is easy enough to find differences in the data between more healthy subjects and patients suffering from one or more age-related conditions. It is a harder task to build upon that data in order to find useful therapies. Aging causes swee...

This study used mice to evaluate how their lifestyles - eating fatty foods vs. healthy and exercising vs. not - affected the metabolites of their offspring. Metabolites are substances made or used when the body breaks down food, drugs or chemicals, or its own fat or muscle tissue. "We have previously shown that maternal and paternal exercise improve health of offspring. Tissue and serum metabolites play a fundamental role in the health of an organism, but how parental exercise affects offspring tissue and serum metabolites has not yet been investigated."
Researchers used targeted metabolomics - the study of metaboli...

Aubrey de Grey Establishes the Longevity Escape Velocity Foundation
Aubrey de Grey, co-founder of the Methuselah Foundation and later the SENS Research Foundation (SRF), funding the latter organization with $13M of his own resources to add to the donations of philanthropists, has over the past year separated from the SRF, for reasons that I intend to neither discuss nor have a public opinion on. Per his presentation at the recent Longevity Summit Dublin, he has now founded the Longevity Escape Velocity (LEV) Foundation in collaboration with the Ichor Life Sciences principals to continue to bring funding into the programs that he believes need to happen in order to unblock important lines o...

Back to Debating Limits to Human Life Span Again
While it is self-evident that longevity is limited in the practical sense, in that one or more degenerative processes of aging eventually make it so unlikely for survival to continue that everyone dies somewhere before age 120, that doesn't mean that longevity is limited in any other sense. If we alter the consequences of the underlying processes of aging, by repairing the damage that they cause, by changing the process, and so forth, then longevity will increase. While the authors of today's open access paper make generally sensible statements about the nature of aging, they seem far too skeptical that anything of practic...

RNA Splicing Dysfunction in Alzheimer's Disease
RNA splicing is the process by which RNA is assembled from portions of a gene, joining exon sequences together while omitting intron sequences. Like all aspects of cellular biochemistry, RNA splicing runs awry with age in a variety of ways, and this is thought to lead to dysfunction in cells. Here, researchers dive into a very specific issue in RNA splicing that appears associated with Alzheimer's disease, though as always in this sort of research one has to ask whether the effect size is meaningful, and whether the animal models are decent reflections of what happens in humans. Mice do not naturally develop Alzheimer's, a...

In Other Words: The Measure of a Mole
When we encounter the word mole, some of us might think of a small, fuzzy animal that burrows in gardens, or perhaps the common, pigmented marks on our skin. But in chemistry, the mole is a key unit of measurement; its name is derived from the word molecule. Similar to how “dozen” is another way of saying 12, “mole” is another way of saying 602,214,076,000,000,000,000,000 (that’s about 602 billion trillion), specifically for elementary entities such as molecules and atoms. Scientists sometimes abbreviate this number as 6.02 x 1023, which is why Mole Day is celebrated from 6:02 a.m. to 6:02 p.m. on October 23 each...

An Update on Senolytics Company Cleara Biotech
Senescent cells accumulate with age, and that accumulation is responsible for a meaningful fraction of degenerative aging. Many groups are working on ways to remove these cells and thereby reverse aspects of aging. Among their number, Cleara Biotech was founded four years ago on to advance initially promising work on the FOXO4-p53 interaction in cellular senescence, a possible targeted way to destroy senescent cells. This approach will join the numerous other mechanisms already being exploited as the basis for potential rejuvenation therapies.
A couple of companies have been looking into FOXO4 biochemistry in the co...

National Chemistry Week: Recent Interviews With NIGMS-Funded Chemists
Credit: ACS Website.
It’s almost National Chemistry Week (NCW)! Each year, the American Chemical Society (ACS) unites scientists, undergraduate students, high school chemistry clubs, and other groups through this community-based program to reach the public—especially elementary and middle school students—with positive chemistry messages.
Local groups plan and coordinate NCW events, so while they vary across the country, they often present chemistry education through hands-on science activities to local schools, museums, scouting groups, or Saturday Science events. Lily Raines, Ph.D., manager at the ACS Office of ...

Air Pollution Correlates with Risk and Outcome of Stroke
Exposure to air pollution tends to inversely correlate with wealth and socioeconomic status, both of which clearly correlate with health in epidemiological studies. More careful studies of similar populations with differing exposure, and what is known of the biochemistry of tissue interaction with particulate matter, make it reasonable to think that the effects of particulate air pollution on chronic inflammation - and thus pace of development of atherosclerosis - play a role in the comparatively poor health of those people in regions of greater pollution. One of the outcomes of atherosclerosis is stroke, and as noted here...

About That Cancer Moonshot
BY KIM BELLARD
Joe Biden hates cancer. He led the Cancer Moonshot in the Obama Administration, and, as President, he reignited it, vowing to cut death rates in half over the next 25 years. Last month, on the 60th anniversary of President Kennedy’s historic call for an actual moonshot, he vowed “to end cancer as we know it. And even cure cancers once and for all.”
But, as several recent studies show, cancer is still surprising us.
