Research Overview
Orexin-A
Preclinical studies link orexin signaling to arousal, learning, and memory consolidation, making orexin-A a candidate for cognition-related research. It is not an approved cognitive enhancer and remains an experimental peptide.
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.
