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.
ACE-031
ACE-031 produced increases in lean mass in early studies, but development was curtailed after safety concerns and variable efficacy. Its literature remains important because it validated activin receptor blockade as a muscle-building strategy.
