Research Overview
Thymalin
Thymalin appears in Soviet/Russian clinical literature as a thymus peptide complex used to normalize immune parameters after illness, surgery, or radiation exposure. Reports commonly focus on changes in lymphocyte subsets, phagocytic activity, and infection frequency rather than a single isolated peptide mechanism.
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.
