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.

Indolicidin

Indolicidin has been extensively studied as a prototype antimicrobial peptide with activity against bacteria, fungi, and some viruses. Research has also explored its use in anti-biofilm strategies and as a template for next-generation synthetic antimicrobial peptides.
