Research Overview
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.
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.
