Thymosin Alpha-1 and LL-37 both support immune function but through very different mechanisms. Thymosin Alpha-1 modulates T-cell function and overall immune response, while LL-37 is a human cathelicidin with direct antimicrobial activity against bacteria, viruses, and fungi. Understanding these differences helps researchers select the appropriate peptide for specific immune-related studies.
