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.
NGF
NGF is one of the most established growth factors in neurobiology and has been investigated for both central and peripheral neuronal repair. Its strongest cognitive relevance comes from supporting basal forebrain cholinergic neurons and downstream memory circuitry.
