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-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.
