Research Overview
hBD-1
hBD-1 has been studied as part of the oral mucosal defense system and is linked to host resistance against dental pathogens. Research spans periodontitis, candidiasis, and epithelial barrier biology.
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.
