Blank credentials
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 is a monthly livestream hosted by Dr. Oliver Medvedik which covers the latest aging research papers.
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...
Pink Hourglass
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...
Emma Teeling Interview Image
Emma Teeling is a professor at University College of Dublin, and her research focuses on bats. In this interview, Emma explains why many bats, despite having tiny body sizes and leading very metabolically demanding lifestyles, are so amazingly long-lived. Will we ever be able to learn these animals' secrets of beating the odds? Emma is...
Infectious disease
A meta-analysis published in GeroScience has shown that the well-studied drug rapamycin has positive effects on infection in mice, but dietary restriction seems to worsen the problem. Aging, immunity, and interventions This paper begins with the well-known information that aging impairs the immune system, harming its effectiveness against infectious diseases [1] while causing systemic inflammation...
Blood cancer
New research published in Cancer Discovery has outlined a potential new method of using senescent cells to encourage the immune system to attack cancer [1]. Senescent cancer cells and immune clearance Cellular senescence is a stress response [2], and cancer cells within tumors undergo significant stress: they lose access to oxygen and nutrients, they divide...
