Mechanism of Action
BPC-157 (Body Protection Compound-157) is a synthetic pentadecapeptide derived from a partial sequence of body protection compound isolated from human gastric juice. Its principal mechanism involves modulation of the nitric oxide (NO) signaling system. Research shows BPC-157 activates endothelial nitric oxide synthase (eNOS) through interaction with the Src-Caveolin-1 complex, facilitating NO-mediated vasodilation and endothelial barrier stabilization in experimental wound models.
At the receptor level, BPC-157 upregulates vascular endothelial growth factor receptor 2 (VEGFR2) expression on endothelial cells, driving angiogenic responses and promoting capillary network formation in tissue-defect models. Parallel studies implicate the FAK-paxillin signaling axis, governing cytoskeletal reorganization, cell migration, and ECM remodeling — processes central to fibroblast recruitment and wound scaffold assembly.
BPC-157 also demonstrates interactions with central dopaminergic and serotonergic systems in CNS-focused in vivo research. Its proline-rich linear structure, lacking disulfide bonds, confers conformational rigidity and resistance to enzymatic degradation in aqueous research environments.
