Long-term l-serine administration reduces food intake and improves oxidative stress and sirt1/NFB signaling in the hypothalamus of aging mice

Short chains of amino acids that act on specific receptors throughout the body, therapeutic peptides interact with highly selective targets

Furthermore, the link between astrocytic metabolism and neurodegeneration is gaining traction: during brain aging or degenerative processes, the efficiency of astrocyte-neuron metabolic couplingcritical for glutamate homeostasis via transporters like GLT-1 and GLASTdeclines, leading to reduced glutamate clearance, extracellular accumulation, and NMDA receptor-mediated excitotoxicity, which drives neuronal dysfunction
