Ergothioneine improves healthspan of aged animals by enhancing cGPDH activity through CSE-dependent persulfidation

9 months 2 weeks ago
Ergothioneine (ET), a dietary thione/thiol, is receiving growing attention for its possible benefits in healthy aging and metabolic resilience. Our study investigates ET's effects on healthspan in aged animals, revealing lifespan extension and enhanced mobility in Caenorhabditis elegans, accompanied by improved stress resistance and reduced age-associated biomarkers. In aged rats, ET administration enhances exercise endurance, muscle mass, and vascularization, concomitant with higher NAD^(+)...

Depressive intensity, duration, and their associations with cognitive decline: a population-based study in Korea

9 months 2 weeks ago
Existing epidemiological studies have ignored the effect of depressive duration on cognitive decline despite the presence of biological cues and understudied the depression-cognition association in Asian countries in the context of increasing cognitive burden worldwide. We aimed to comprehensively characterize the effects of depressive duration and intensity on cognitive decline at the population level. A total of 6406 individuals from the Korean Longitudinal Study of Aging (KLoSA) from 2010 to...

Immune evasion through mitochondrial transfer in the tumour microenvironment

9 months 2 weeks ago
Cancer cells in the tumour microenvironment use various mechanisms to evade the immune system, particularly T cell attack¹. For example, metabolic reprogramming in the tumour microenvironment and mitochondrial dysfunction in tumour-infiltrating lymphocytes (TILs) impair antitumour immune responses^(2-4). However, detailed mechanisms of such processes remain unclear. Here we analyse clinical specimens and identify mitochondrial DNA (mtDNA) mutations in TILs that are shared with cancer cells....
