Research Overview
IFN-alpha-2b
Extensively studied recombinant type I interferon with direct antiviral and immunoregulatory effects. Clinical literature spans hepatitis treatment, antiviral research, and immune-oncology contexts.
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.
