How a Neurotransmitter May Be the Key in Controlling Alzheimer’s Toxicity

Posted by in categories: biotech/medical, life extension, neuroscience

Summary: Study reveals how somatostatin and copper affect amyloid beta in Alzheimer’s disease pathology.

With nearly 50 million dementia patients worldwide, and Alzheimers’s disease is the most common neurodegenerative disease. Its main symptom is the impairment of general cognitive abilities, including the ability to speak or to remember.

Another byproduct of aging: Hypermutations in the brain

Posted by in categories: biotech/medical, life extension, neuroscience

Throughout life, cells of the body acquire somatic mutations. In frozen post-mortem human brains, researchers from Yale University have found that somatic, or non-inherited, mutations are considerably more likely to accumulate in roughly 6% of brains, and these “hypermutable” brains are typically 40 years of age or older.

The behavior, comparable to clonal hematopoiesis in the bone marrow that can result in blood cancer in elderly people, is attributed to cell lines with mutations that outcompete other cell lines.

This is the first large-scale study of somatic mutations in human brains. Scientists were not expecting to find this hypermutability in older populations.

“DEATH DEFANGED Cryonics, Cryothanasia and the Future of Sentience” with David Pearce, Author, Philosopher and well-known TransHumanistThis service will be on ZOOM and YouTube Live Stream only, not in person.
Zoom at 6:00 PM Eastern Time.
Live Stream at 7:00 PM Eastern Time.
Stay after the close of the YouTube streaming for the Zoom After Party until??:00 pm. Enjoy fellowship in the extended discussions with Neal and Immortalists & Friends from Around the World, sharing bold ideas on health, longevity, and technology!(Note: Mr. Pearce was scheduled last month to give a presentation but due to circumstances beyond our control we did not have that presentation. We look forward this month to have David Pearce join us!)David Pearce is the author of 4 major works:“The Hedonistic Imperative”, “The Biointelligence Explosion: How Recursively Self-Improving Organic Robots will Modify their Own Source Code and Bootstrap Our Way to Full-Spectrum Superintelligence”, “Singularity Hypotheses: A Scientific and Philosophical Assessment”, & “Can Biotechnology Abolish Suffering?”
The Hedonistic Imperative (1995) advocates the use of biotechnology to abolish suffering throughout the living world. In 1998, he co-founded the World Transhumanist Association (H+) with Nick Bostrom. Transhumanists believe in the use of technology to overcome our biological limitations.
Currently, Pearce is a fellow of the Institute for Ethics and Emerging Technologies, and sits on the futurist advisory board of the Lifeboat Foundation. He is also the director of bioethics of Invincible Wellbeing and is on the advisory boards of the Center on Long-Term Risk, the Organization for the Prevention of Intense Suffering and since 2021 the Qualia Research Institute.

Alcohol consumption and telomere length: Mendelian randomization clarifies alcohol’s effects

Posted by in categories: business, genetics, life extension

Observational studies of the relationship between alcohol use and telomere length have produced conflicting results. The largest such study to date, of 4,567 individuals, found no association between alcohol intake and either baseline or longitudinal change in telomere length [9]. Another analysis of two American cohorts (n = 2623) also reported null findings [10]. On the other hand, a few small studies (sample size range: 255‑1800) have observed associations with heavy drinking or AUD. Participants with AUD have been reported to have shorter telomeres compared to healthy controls [11]. A longitudinal study of Helsinki businessmen observed that higher midlife alcohol consumption was associated with shorter telomere length in older age [8]. Drinking 30 g/day of alcohol in older participants was associated with shorter telomeres in a Korean study [12]. Associations were stronger in those experiencing the alcohol flush reaction, raising the intriguing possibility that acetaldehyde, ethanol’s toxic breakdown product, is mechanistically involved. In a recent review of 27 studies, 10 showed significant associations between alcohol use and telomere length [13]. The studies included cross-sectional and longitudinal designs. The majority comprised European participants with ages ranging from the third to seventh decade. Most studies observed positive associations between alcohol and LTL. However heterogeneity between studies in methods of quantifying telomere length and categorizing alcohol intake hindered meta-analysis and aggregation of the data.

MR seeks to identify potentially causal determinants of an outcome. It estimates the association between genetically predicted levels of an exposure and an outcome of interest. Residual confounding and reverse causation aim to be less of a concern than in most other methods of analyzing observational data [14]. With MR, genetic proxies can be used to study the effects of genetically-predicted variability in alcohol consumption or AUD risk. To our knowledge, no MR study of alcohol and telomere length has yet been attempted.

We conducted a large observational study of two alcohol phenotypes, alcohol consumption and AUD, and leucocyte. We then performed linear MR analyses to investigate the evidence for a causal effect between alcohol consumption/AUD and LTL. Estimates generated by our observational and genetic methods were compared. Genetic distinction between different alcohol use traits motivates their separate analysis. Quantity/frequency measures such as drinks per week and AUDIT-C (Alcohol Use Disorders Identification Test Consumption, a 3 item screening tool), while moderately genetically correlated with AUD, have distinct patterns of genetic correlation with other traits [13]. Furthermore, as there has been much speculation about potential J-shaped relationships between alcohol and health outcomes [15], we performed a non-linear MR analysis to examine the shape of the relationship between alcohol consumption and telomere length.

Scientists develop blueprint for turning stem cells into sensory interneurons

Posted by in categories: biotech/medical, life extension

Researchers at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have developed a first-of-its-kind roadmap detailing how stem cells become sensory interneurons—the cells that enable sensations like touch, pain and itch.

The study, conducted using embryonic stem cells from mice, also identified a method for producing all types of sensory interneurons in the laboratory.
