Thymostimulin (TP-1)
Overview
Thymostimulin is a polypeptide extract derived from bovine thymus tissue containing multiple biologically active thymic peptides. It acts on T-lymphocyte maturation and differentiation by mimicking thymic hormone activity. The therapeutic rationale centers on restoring or augmenting immune function in states of T-cell deficiency or immunosuppression.
Key Research Findings
Clinical investigations in the 1980s and 1990s explored thymostimulin in immunodeficiency states, chronic infections, and as an adjunct to cancer therapy, though results were inconsistent. Modern regulatory interest has diminished due to lack of standardized composition and robust efficacy data in controlled trials.

Thymalin
InvestigationalA peptide bioregulator originally extracted from bovine thymus gland, consisting of a mixture of polypeptides that modulate immune function. Thymalin restores T-cell mediated immunity by promoting T-lymphocyte maturation and differentiation in the thymus. It also normalizes the ratio of T-helper to T-suppressor cells and enhances phagocytic activity of neutrophils and macrophages.
LL-37
Research PhaseThe only human cathelicidin antimicrobial peptide, a 37-amino acid cationic peptide cleaved from the precursor protein hCAP18. LL-37 disrupts microbial membranes through electrostatic interactions and exerts broad-spectrum activity against bacteria, fungi, and enveloped viruses. Beyond direct antimicrobial effects, it modulates innate immunity by recruiting immune cells, promoting angiogenesis, and regulating inflammatory cytokine release.
VIP (Vasoactive Intestinal Peptide)
InvestigationalA 28-amino acid neuropeptide widely distributed in the central and peripheral nervous systems and immune cells. VIP acts through VPAC1 and VPAC2 receptors to produce potent anti-inflammatory effects by inhibiting the production of pro-inflammatory cytokines (TNF-alpha, IL-6, IL-12) and promoting regulatory T-cell differentiation. It also functions as a vasodilator, bronchodilator, and neuromodulator.
Thymosin Alpha 1 (Zadaxin)
InvestigationalA 28-amino acid peptide originally isolated from thymic tissue (thymosin fraction 5) that serves as a potent immunomodulator. Thymosin alpha 1 enhances T-cell maturation, dendritic cell function, and antibody responses by activating Toll-like receptors (TLR2, TLR9) on innate immune cells. It promotes Th1 immune responses and augments vaccine efficacy while modulating inflammatory cytokine production.
