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.

Mifamurtide

Mifamurtide has substantial literature as an innate immune activator and is an approved oncology adjunct in some regions. Research centers on NOD-like receptor signaling, macrophage activation, and downstream cytokine effects.
