Research Overview

Thymogen

Thymogen has been studied as a short thymic peptide-like dipeptide with immunoregulatory activity. The literature focuses on lymphocyte function, cytokine modulation, and use in recurrent respiratory infections or immune suppression states.

HNP-1

HNP-1 has been studied as a key component of neutrophil-mediated host defense against bacteria, fungi, and some enveloped viruses. Literature also reports immunomodulatory effects, including impacts on chemotaxis, cytokine release, and barrier defense.
