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.
LRAP
LRAP is one of the better-known amelogenin-derived peptides in regenerative dentistry because it can influence mineralization-related cell behavior. It remains a research peptide, but it is highly relevant to enamel repair and tooth-tissue engineering.
