Research Overview
HBD-3
Human beta-defensin 3 has been examined in numerous in vitro and animal studies for antimicrobial and immunomodulatory activity. Research suggests it can help defend barrier tissues while influencing cytokine networks, chemotaxis, and epithelial repair.
Thymogen
Thymogen has been studied as a short thymic peptide-like dipeptide with immunoregulatory activity. The literature focuses on lymphocyte function, cytokine modulation, and use in recurrent respiratory infections or immune suppression states.
