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.

Desmopressin

The literature is mixed, but desmopressin has shown memory-related effects in selected populations and experimental paradigms. Its cognitive effects are usually discussed as a vasopressin-pathway probe rather than a primary nootropic.
