Aerobic Exercise Restores Hippocampal Neurogenesis and Cognitive Function by Decreasing Microglia Inflammasome Formation Through Irisin/NLRP3 Pathway

open access: yesAging Cell, EarlyView.
Exercise improved PD pathology and memory by reducing microglial inflammation, apoptosis, and the formation of the NLRP3 inflammasome via irisin signaling. Irisin administration partially replicated the beneficial effects of exercise on PD pathology.

VDAC1‐Targeted NHK1 Peptide Recovers Mitochondrial Dysfunction Counteracting Amyloid‐β Oligomers Toxicity in Alzheimer's Disease

open access: yesAging Cell, EarlyView.
Amyloid‐β (Aβ) oligomers affect VDAC1 electrophysiology and the physiological metabolic cross‐talk between cytosol and mitochondria. The use of a small, synthetic VDAC1‐antagonist peptide, derived from hexokinase, restores mitochondrial functionality, and respiration in cellular models of Alzheimer's disease. ABSTRACT Mitochondrial dysfunction has been

Identification of Senomorphic miRNAs in Embryonic Progenitor and Adult Stem Cell‐Derived Extracellular Vesicles

open access: yesAging Cell, EarlyView.
A senomorphic miRNA cocktail (E5), consisting of miR‐181a‐5p, miR‐92a‐3p, miR‐21‐5p, and miR‐186‐5p, was identified from a pool of miRNAs enriched in extracellular vesicles (EVs) derived from multiple functional human stem cell types. E5 reduces senescence and SASP markers both in cell culture and in aged mice.

Single‐Cell RNA‐Seq Reveals Aging‐Related Impairment of Microglial Efferocytosis Contributing to Apoptotic Cells Accumulation After Retinal Injury

open access: yesAging Cell, EarlyView.
Microglia engage with apoptotic cells via cell‐surface receptors, such as proto‐oncogene tyrosine‐protein kinase MER (MerTK) and Axl; these receptors interact with the bridging molecule growth arrest‐specific 6 (Gas6) on apoptotic cells. Young microglia demonstrate efficient efferocytosis of apoptotic cells, but this process is impaired in aged ...
