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.
GPE
Preclinical studies suggest GPE can reduce neuronal damage and support plasticity-related pathways in the brain. Research interest centers on hippocampal function, which links it to learning and memory paradigms.
