Research Overview
Plecanatide
Clinical trials show plecanatide improves constipation outcomes with a generally favorable tolerability profile. Like linaclotide, it acts locally in the intestinal lumen via GC-C signaling rather than systemic hormone effects.
BDNF
BDNF is repeatedly associated with learning, long-term potentiation, and recovery from neurologic injury in preclinical literature. Direct protein delivery is difficult, so most studies focus on pathways that raise endogenous BDNF or on localized experimental administration.
