Research Overview
HBD-2
Human beta-defensin 2 has been studied extensively for direct microbicidal effects and for its role in shaping mucosal immunity. Preclinical work shows activity against Gram-negative and Gram-positive organisms, with additional effects on leukocyte recruitment and wound defense.
Thymopentin
Thymopentin has a long history of preclinical and clinical investigation as a thymic peptide immunomodulator. Published studies report effects on T-cell subsets, cytokine responses, and immune recovery in recurrent infection settings.
