[ad_1] Exosomes are a class of extracellular vesicle, membrane-wrapped packages of molecules that carry a sizable fraction of the chemical communications that takes place between cells. The various types of extracellular vesicle are presently ordered in a taxonomy by their size rather than any more subtle combination of features. Those subtle features definitely exist; … Read more
[ad_1] TDP-43 is one of a small number of proteins that can become altered in ways that lead to the formation of solid aggregates that, directly and indirectly, cause cell dysfunction and death in the brain. In the case of TDP-43, this proteopathy contributes to amyotrophic lateral sclerosis (ALS), frontotemporal lobar degeneration (FTLD), and … Read more
[ad_1] Today’s open access paper presents an interesting discussion of the apparent lack of age-related autoimmunity in centenarians. The immune system becomes ever more dysfunctional with age, and some of that dysfunction can take the form of maladaptive changes that either (a) allow the immune system to direct attack tissues or (b) disrupt important … Read more
[ad_1] The cost of obtaining transcriptomic and proteomic data, and then using machine learning techniques to develop insights based on that data, has fallen dramatically over the past decade. As a result there is a proliferation of signatures of aging and longevity, as many different research groups analyze many different large transcriptomic and proteomic … Read more
[ad_1] Researchers here identify a mechanism by which the practice of calorie restriction promotes muscle stem cell function, and thus repair and maintenance of muscle tissue. In animal studies calorie restriction is shown to produce both (a) a short-term effect associated with improved regeneration, and (b) a long-term effect in the sense of slowing … Read more
