1. What is Thymalin?

Thymalin is a polypeptide complex originally derived from the thymus of calves and used for its immunomodulatory and regenerative properties. It was developed in Russia in the 1970s and has been studied for its ability to normalize immune function, regulate hematopoiesis, and promote tissue regeneration. Thymalin acts by influencing gene expression related to cell differentiation, apoptosis, and immune system balance.

1 Molecular & Cellular Mechanisms

Immune cell modulation: Enhances differentiation and proliferation of T/B lymphocytes, boosts phagocytosis, and reverses apoptosis in immune cells 【https://pmc.ncbi.nlm.nih.gov/articles/PMC8365293/?utm_source=chatgpt.com】.

Cytokine balancing & anti-inflammation: Attenuates hyperinflammatory cytokines (IL-6, TNFα), upregulates IFNγ/IL2, highstress response proteins (Hsp70/90), and maintains NFκB/p38 signaling for homeostasis .

Lymphoid & hematopoietic support: Restores thymic output and hematopoiesis post-chemotherapy or irradiation, rebalances CD4⁺ T-cell subsets, and supports bone marrow regeneration 【https://pmc.ncbi.nlm.nih.gov/articles/PMC8365293/?utm_source=chatgpt.com】.

Respiratory epithelium & ciliary function: Supports mucociliary clearance by preserving ciliary beat frequency and epithelial health amid inflammatory stress .
