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.
Piscidin-3
Preclinical research indicates strong activity against bacterial membranes and drug-resistant strains. Analogs are being evaluated to balance potency with lower toxicity and better stability.
