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.
Noopept
Noopept has been reported to increase NGF/BDNF-related signaling and improve performance in tasks involving learning and recall. Evidence includes preclinical studies and small human studies, but the overall literature is still modest compared with mainstream cognitive drugs.
