Immune Support Peptides
Peptides investigated for their roles in immune system modulation, thymic function, and immunological research.
Immune Support Peptides: Research Overview
Immune-modulating peptides interact with the thymus gland and immune cell signaling pathways. These compounds are studied for their potential to support immune function through T-cell modulation, cytokine regulation, and thymic hormone mimicry.
Key Peptides
TB-500 (Thymosin Beta-4 Fragment) Derived from thymosin beta-4, TB-500 has immune-modulating properties through its effects on T-cell maturation and anti-inflammatory pathways. The thymus gland naturally produces thymosin proteins that are essential for immune system development.
Epithalon and Immune Aging Research by Khavinson et al. has shown that Epithalon may support immune function in aging models by influencing pineal-thymic interactions. The pineal gland's production of melatonin plays a role in immune regulation, and Epithalon research has explored its effects on this pathway.
BPC-157 Immune Effects BPC-157 has demonstrated immune-modulating properties in research, including anti-inflammatory effects and modulation of the nitric oxide system, which plays a role in immune cell signaling.

Frequently Asked Questions
How does TB-500 relate to immune function?
TB-500 is derived from thymosin beta-4, a protein produced by the thymus gland that plays a crucial role in T-cell maturation and immune system development. It has demonstrated immune-modulating and anti-inflammatory properties in research.
What role does the thymus play in immunity?
The thymus is where T-cells mature and differentiate. It produces thymosin proteins (including thymosin beta-4) that regulate immune cell development. Thymic function declines with age, contributing to immune senescence.
