Autophagy

A cellular recycling process where damaged organelles, misfolded proteins, and other cellular debris are engulfed by double-membrane vesicles (autophagosomes) and delivered to lysosomes for degradation. Autophagy plays a crucial role in cellular quality control, stress adaptation, and longevity. Research into peptides related to GH pathways, mTOR signaling, and metabolic regulation frequently intersects with autophagy mechanisms, as these pathways are key regulators of the autophagic process.
