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.
Neuropeptide S
Animal studies suggest NPS can reduce anxiety-like behavior while altering wakefulness and alertness through the NPS receptor system. Human cognitive data are very limited, and it has no approved clinical indication.
