1.MECHANISM OF ACTION

Mas-ETH Peptide exerts its biological activity through selective binding to MRGPRX1 (Mas-related G protein-coupled receptor X1), predominantly expressed on peripheral sensory neurons and immune cells. Upon receptor activation, it triggers intracellular signaling cascades (e.g., Ca²⁺ mobilization and MAPK pathway activation) that modulate two key biological responses: 1) Suppression of nociceptor excitability, leading to analgesic effects by reducing pain signal transmission to the central nervous system; 2) Inhibition of pro-inflammatory cytokine release (e.g., IL-1β, TNF-α) from immune cells, alleviating peripheral inflammation. Additionally, its interaction with MRGPRX1 mediates pruritic signaling, making it a valuable tool for studying itch pathways.
