A new study suggests that depleting a subset of stem cells that overproduces myeloid cells can rescue age-related immunosenescence [1]. Thrown off balance Immunosenescence, the gradual decline in the immune system’s abilities, is one of the hallmarks of aging [2]. Moreover, many scientists view it as one of the most consequential processes of aging, as...

Researchers publishing in Nature Biotechnology have demonstrated a method of protecting mass-produced stem cells from the immune system, with strongly positive results in two different animal models. Fake ID for the immune system While it would be ideal to create stem cells from each person's existing cells to replace that particular person's needs and losses,...

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...

In a paper published in Frontiers in Endocrinology, researchers have shown that transplanted young ovarian tissue improves the immune function of old recipient mice even if they are hormone-depleted [1]. Not just a reproductive matter Although women generally live longer than men, women spend almost half of their lives in poorer health due to reproductive...
