Oxidative and nitrosative stress alter signaling pathways that regulate tight junction protein trafficking, leading to internalization or redistribution of claudins and occludin away from the apical membrane and weakening their anchorage to actin
Both BPC-157 and TB-500 play a role in the actin regulation process
TB-500's regenerative pathways TB-500 operates through distinct but complementary pathways to BPC-157
