Research Overview
HD5
HD5 has been widely studied in intestinal innate immunity, particularly for its role in defending crypts against bacterial invasion. Preclinical literature supports activity against multiple microbes and links altered HD5 biology with gut barrier dysfunction.
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.
