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.

Cotadutide

Phase 2 studies reported dose-dependent weight loss and favorable changes in glycemic and liver-related markers. It is one of the most cited synthetic dual-agonist peptides for obesity research.
