Research Overview

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.

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.
