Research Overview

Glatiramer Acetate

Glatiramer acetate has extensive literature in relapsing-remitting multiple sclerosis, where it is used to shift immune activity away from pro-inflammatory pathways. It remains one of the best-studied peptide-based immunomodulators and a benchmark compound for autoimmunity research.

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.
