Background: Autophagy, a catabolic process essential for maintaining cellular homeostasis, declines with age and unhealthy lifestyles, contributing to neurodegenerative diseases. Probiotics, including Milmed yeast, have demonstrated anti-inflammatory antioxidant properties. This study evaluated the activity of on BV-2 microglial cells in vitro vivo model Caenorhabditis elegans (C. elegans) restoring autophagic processes. Methods: were incubated S. cerevisiae (Milmed treated yeast or untreated yeast) then stimulated lipopolysaccharide (LPS). mRNAs factors enzymes assessed by qPCR; mTOR NRF2 ELISA. pNRF2 compared cytosolic was immunofluorescence. The longevity, body size, reactive oxygen species (ROS) levels C. measured fluorescence microscopy. Results: Treatment YPD cultured dried powder obtained from it promoted flux, as shown increased expression Beclin-1, ATG7, LC3, p62 inhibition mTOR, It also enhanced response increasing NRF2, SOD1, GPX; moreover, enhanced, dietary supplementation prolonged survival reduced age-related ROS accumulation without changing gst-4. pro-longevity effect found be dependent SKN-1/Nrf2 activation, absence benefit skn-1 mutants. Conclusions: demonstrates significant pro-autophagy effects elegans, thereby extending lifespan improving stress resistance, which, together previously activity, highlights its role highly effective probiotic beneficial health effects. Activation SKN-1/NRF2 pathway modulation autophagy support therapeutic potential neuroprotection healthy aging.
