Research Overview
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.
HBD-2
Human beta-defensin 2 has been studied extensively for direct microbicidal effects and for its role in shaping mucosal immunity. Preclinical work shows activity against Gram-negative and Gram-positive organisms, with additional effects on leukocyte recruitment and wound defense.
