The Journal Club returns on Tuesday 28th March at 12:00 PM Eastern time to the Lifespan.io Facebook channel. This month Dr. Oliver Medvedik will be exploring a recent study which looked at the effects of prolonged fasting on human macrophages and how metabolites from that fasting increased median lifespan in Caenorhabditis elegans.
Abstract
Periodic prolonged fasting (PF) extends lifespan in model organisms and ameliorates multiple disease states both clinically and experimentally owing, in part, to its ability to modulate the immune system. However, the relationship between metabolic factors, immunity, and longevity during PF remains poorly characterized especially in humans.
This study aimed to observe the effects of PF in human subjects on the clinical and experimental markers of metabolic and immune health and uncover underlying plasma-borne factors that may be responsible for these effects.
