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.

HBD-3

Human beta-defensin 3 has been examined in numerous in vitro and animal studies for antimicrobial and immunomodulatory activity. Research suggests it can help defend barrier tissues while influencing cytokine networks, chemotaxis, and epithelial repair.
