Proven Health Benefits of Thymosin Alpha 1

Eradicates Bacteria, Virus, and Fungi

Thymosin alpha 1 possesses strong antimicrobial properties that can help ward off infection:

1. In patients with severe sepsis (presence of harmful microorganisms in the blood), thymosin alpha 1 administration improved clinical outcome without any adverse effect. [1]
2. In patients with chronic hepatitis B and C, thymosin alpha 1 administration for 6 months normalized liver enzyme levels, which is suggestive of improved liver function. [2-4]
3. In mice with fungal infection, thymosin alpha 1 increased the production of phagocytes, which are cells capable of engulfing and absorbing bacteria. [5]
4. Thymosin alpha 1-based immunomodulatory therapy was associated with a significant reduction in mortality in septic patients. [6]
5. Thymosin alpha 1 administration in septic patients was also associated with increased survival rate, alleviation of illness, and short ICU stay and mechanical ventilation time. [7]

Boosts the Function of Certain Immune Cells

By affecting the production of certain immune cells, thymosin alpha 1 exerts its immune-boosting properties:

1. Thymosin alpha 1 is known to augment T-cell function. [8-9]
2. Thymosin alpha 1 also helps regulate both the innate and adaptive immune systems. [10-11]
3. Thymosin alpha 1 has the ability to increase CD4+/CD8+ ratio. [12-13]
4. By activating and stimulating certain signaling pathways, thymosin alpha 1 boosts the production of immune-related cytokines. [14]
5. By selectively stimulating the release of luteinizing hormone (LH), thymosin alpha 1 indirectly strengthens the immune function. [15]
6. In patients with sepsis, thymosin alpha 1 restored the dysregulated immune response. [16-17]
7. A cell study found that thymosin alpha 1 inhibited HIV-1 and human T lymphotropic virus 1 infection by stimulating the release of CD8(+) cells. [18]

Suppresses Cancer and Tumor Growth

There’s also increasing evidence supporting the anti-cancer and antitumor properties of thymosin alpha 1:

1. By regulating cytokine secretion and repairing damaged immune system, thymosin alpha 1 may help reduce cancer incidence. [19]
2. In stage IV human breast cancer model, thymosin alpha 1 treatment was associated with significantly slow tumor growth. [20]
3. In patients with metastatic melanoma and advanced non-small cell lung cancer, thymosin alpha 1 treatment prolonged survival. [21]
4. In patients with hepatitis B virus-associated liver cancer, thymosin alpha 1 therapy improved liver function and significantly prolonged recurrence‑free and overall survival. [22]
5. Thymosin alpha 1 exerts its anti-tumor effects mainly by increasing the secretion of various T cell lymphokines, activating T4 helper cells to promote lymphocyte activity, and increasing the cytotoxicity of natural killer cells. [23-25]
6. Administration of thymosin alpha 1 in cancer patients was associated with reduced risk of dying and improved disease‐/progression‐free survival. [26]
7. In patients with metastatic lung cancer, thymosin alpha 1 treatment was associated with complete disappearance of lesions. [27]
8. A cell study found that exposure of human breast cancer cells to thymosin alpha 1 induced apoptosis (programmed cell death). [28]
9. Administration of thymosin alpha 1 in cancer patients increased the anti-tumor effect of chemotherapy while markedly reducing side effects of the treatment. [29]
10. In tumor-bearing mice, thymosin alpha 1 significantly delayed tumor growth and prolonged survival time. [30]
11. When combined with human immunoglobulin, thymosin alpha 1 can produce stronger chemotherapeutic effect against breast cancer cells in mice. [31]
12. When combined with the chemotherapeutic drug dacarbazine, thymosin alpha 1 can improve overall survival of patients with metastatic melanoma (cancer that spreads to other sites). [32-33]
13. In human lung cancer cell lines, thymosin alpha 1 administration inhibited cellular proliferation and cell migration through its antioxidant properties. [34-35]

Accelerates the Wound Healing Process

Studies also show that thymosin alpha 1 can accelerate tissue recovery:

1. When given either topically or in the form of injections, thymosin alpha 1 accelerated wound healing in mice. [36]
2. A cell-based study found that thymosin alpha 1 accelerates wound healing by promoting formation of new blood vessels and cell migration at the site of injury. [37]
3. In rat kidney cells, thymosin alpha 1 prevented programmed cell death and renal scarring. [38]

Fights Inflammation

There’s also a good deal of evidence suggesting that thymosin alpha 1 has potent anti-inflammatory properties:

1. In rats with acute liver failure, thymosin alpha 1 reduced liver inflammation. [39]
2. Thymosin alpha 1 may help prevent tissue injury by reducing the release of inflammatory factors and cytokines, and the levels of IL-10 to control inflammation. [40-41]
3. Thymosin alpha 1 also reduces inflammation by suppressing pro-inflammatory TNF-α. [42-45]
4. A cell-based study also found that thymosin alpha 1 protects against inflammatory allergy. [46]
5. A 2019 study published in the Neuroscience Bulletin found that thymosin alpha 1 inhibited pro-inflammatory cytokines in the spinal cord. [47]
6. In a mouse model of cystic fibrosis, a condition characterized by abnormal production of thick mucus, thymosin alpha 1 administration reduced inflammation. [48]

Increases Vaccine Effectiveness

Thymosin alpha 1 is the ultimate immune system booster. Studies show that this peptide can naturally enhance the effectiveness of certain vaccines:

1. In patients who are susceptible to infection, thymosin alpha 1 administration enhanced the immunogenicity (ability to provoke an immune response) of the pandemic influenza vaccine. [49]
2. In elderly patients, administration of thymosin alpha 1 together with influenza vaccine enhanced vaccine responses. [50-51]
3. In animal models, thymosin alpha 1 enhanced the efficacy of the classical swine fever vaccine. [52]
4. A study found that thymosin alpha 1 can increase vaccine effectiveness by restoring immune system homeostasis. [53]

Improves Cognitive Function

A 2017 study published in the Neuroscience bulletin found that administration of thymosin alpha 1 in neonatal mice improved cognitive function. Compared with the control group, thymosin alpha 1-treated mice had better cognitive abilities in early life, increased levels of growth factors, and decreased levels of inflammatory substances. [54]
