L
LL-37
Cathelicidin · hCAP-18
LL-37 is the only human cathelicidin antimicrobial peptide, a 37-amino acid peptide with broad-spectrum antimicrobial activity against bacteria, viruses, and fungi. Beyond direct antimicrobial action, it modulates immune responses, promotes wound healing, and has anti-biofilm properties.
Lactoferricin
Lfcin · LfcinB
Lactoferricin is an antimicrobial peptide derived from lactoferrin that exhibits potent antibacterial, antiviral, and immunomodulatory properties. This cationic peptide demonstrates broad-spectrum antimicrobial activity against both gram-positive and gram-negative bacteria.
T
Thymosin Alpha-1
Tα1 · Ta1
Thymosin Alpha-1 is a naturally occurring 28-amino acid peptide originally isolated from thymic tissue. It is a potent immunomodulator approved in over 35 countries for treating hepatitis B, hepatitis C, and as an immune adjuvant. It enhances both innate and adaptive immunity without causing immune overstimulation.
Thymalin
Thymic Factor · Thymulin
Thymalin is a synthetic thymic peptide that regulates immune system function by stimulating T-cell production and maturation. This bioregulator peptide mimics natural thymic hormones to support immune surveillance and cellular repair mechanisms.
Thymogen
EW Dipeptide · Glutamyl-tryptophan
Thymogen is a synthetic dipeptide (glutamyl-tryptophan) that enhances immune system function by modulating T-cell activity and supporting thymic hormone production. This peptide shows promise for immune deficiency states and age-related immune decline.
V
VIP
Vasoactive Intestinal Peptide · Vasoactive Intestinal Polypeptide
VIP (Vasoactive Intestinal Peptide) is a 28-amino acid endogenous neuropeptide with potent anti-inflammatory, immunomodulatory, neuroprotective, and vasodilatory properties. It is researched for CIRS (Chronic Inflammatory Response Syndrome), autoimmune conditions, and pulmonary hypertension.
Vilon
Lys-Glu · KE
Vilon (KE) is a synthetic dipeptide (Lys-Glu) from the Khavinson bioregulator program; the shortest of the bioregulatory peptides. It targets thymic and immune tissue, researched for immune system restoration, T-cell maturation support, and immunosenescence reversal in aging.
