The fourth installment of our Rapamycin for Longevity series where we explore rapamycin and its effect on human longevity. In series 4 we go over the paper "Effect of rapamycin on aging and age-related diseases - past and future" written by Ramasamy Selvarani, Sabira Mohammed, and Arlan Richardson

Pharmaceutical interventions with regards to aging requires targeting multiple pathways, thus there is rationale to test combinations of drugs that target different but overlapping processes. A multifaceted  approach to treatment of aging in order to determine if combining drugs shown to extend lifespan and healthy aging in mice would have greater impact than any individual drug.

A continuation of our Rapamycin for Longevity series exploring rapamycin and its effect on human longevity. Part 1 of 2.

Part 2 of our second series on Rapamycin for Longevity, where we explore rapamycin and its effect on human longevity. Part 2 of 2.

A continuation of our Rapamycin for Longevity series, where we explore rapamycin and its effect on human longevity. A brief explanation and overview of Harrison et al’s groundbreaking rapamycin study, aptly titled “Rapamycin fed late in life extends lifespan in genetically heterogeneous mice.”

Learn about cellular senescence and the hyperfunction theory of aging and how rapamycin treatment ties into these subjects.

Sleep is incredibly important for the human body as a whole as well as on the cellular level. What causes alterations in the quantity and quality of sleep and what are the consequences of these changes are quite important questions. What changes exacerbate aging and a more dysfunctional physiology and what changes are caused by aging that are detrimental to your health as well. We will cover the characterization of related changes in sleep structure on both the macro and micro scale and cover the differences between men and women when it comes to sleep and age.

The first of our Rapamycin for Longevity series where we explore rapamycin and its effect on human longevity.

As the lexicon of health, longevity, and anti-aging enthusiasts continues to evolve, one term - 'autophagy' - has solidified its place within the discourse. Nonetheless, a relatively lesser-known offshoot, 'mitophagy,' or mitochondrial-specific autophagy, remains more obscure despite its critical significance. Recent evidence has begun to show how critical this process is in maintaining proteostasis within a cell or tissue and how dysregulation of this process can result in the accumulation of damaged mitochondria.
