Research Overview
IFN-beta-1a
Widely studied recombinant interferon beta preparation with a strong evidence base in immune modulation and antiviral biology. Its clinical use demonstrates predictable pharmacology and class-typical interferon effects.
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.
