What is Thymosin Alpha-1?
Thymosin alpha-1 (TA-1) is a protein that consists of 28 amino acids and acts as a potent regulator of immune function [1]. It is a naturally occurring peptide fragment and was first isolated from tissue in the thymus gland, which plays the role of making T-cells and ensuring they mature properly.
T-cells are a vitally important part of the adaptive immune system as they assist it in remembering past infections and improving the function of other immune system cells. After being produced by the thymus gland, T-cells are discharged into the lymphatic system and then disperse around the body to defend against viruses and diseases.
Due to these qualities, thymosin alpha-1 has long been recognized as an immune-enhancing, immune-modulating, as well as an immune-restoring agent [2].
Thymosin alpha-1 has a pleiotropic mechanism of action, and works through toll-like receptors in both myeloid and plasmacytoid cells, thus activating signaling pathways within the immune system and stimulating the production of immune-related cytokines and other molecules that help coordinate the activities of various cells [3].
By targeting the toll-like receptors, thymosin alpha-1 can stimulate the active immune response which some studies have indicated are essential for fighting viral, bacterial, and fungal infections and cancers, as well as stimulation of posterior humoral immunity.
Following its discovery it has been studied in a variety of contexts, including for cystic fibrosis, respiratory disorders, and chronic hepatitis.
Thymosin Alpha-1 Benefits
Below we highlight some of the documented thymosin alpha-1 benefits in relation to potential contexts under which the peptide may be studied.
Thymosin Alpha-1 for Body Composition
There is evidence to suggest that thymosin alpha-1 administration may have benefits in relation to body composition and muscle growth.
Recent research has indicated that thymosin alpha-1 has a range of antioxidant properties [4, 5]. Antioxidants are a group of compounds that “fight” free radicals and are used by many bodybuilders for their potential to enhance recovery from training or other physical activity.
Thymosin alpha-1 may also provide wide-ranging benefits to subjects involved in physical activities that lead to high-levels of tissue stress and inflammation. The peptide plays a central role in modulating dendritic cells, which sense infection and tissue stress, collectively translating this information into an appropriate immune response [6, 7].
Data suggests that instructive immunotherapy with thymosin alpha-1, via DCs and tryptophan catabolism, may assist to control inflammation, immunity, and tolerance in a variety of clinical settings [6, 7].
Thymosin Alpha-1 as a Treatment of Autoimmune Disease
Clinical studies point to various potential benefits that thymosin alpha-1 may have on the immune system and to the treatment of autoimmune diseases.
One study has noted that diseases characterized by deregulation of immune and/or inflammatory responses are associated with serum levels of thymosin alpha-1 significantly lower than those of healthy individuals. This data is consistent with the role of thymosin alpha-1 as a regulator of immunity, tolerance and inflammation, demonstrating that low levels of thymosin alpha-1 in the body can lead to reduced immune function and susceptibility to disease [8].
Research in mice without thymus glands shows that thymosin alpha-1 alone is enough to restore immune function and prevent wide-spread infection. One study suggested that due to the immune stimulating effects of thymosin alpha-1, the compound would be expected to show utility for treatment of immune suppression, whether related to aging or to diseases such as infection or cancer [3, 9].
Thymosin Alpha-1 for Promoting Nerve Growth
Due to its effects on the immune system, thymosin alpha-1 may also help to promote nerve growth. The immune system plays a key role in the growth, development, and maintenance of the central nervous system.
Research conducted on mice indicates TA-1 as a prominent potentiator of neuro-development and that peripheral administration of the peptide can actually boost cognitive function. One study has suggested that the peptide alters the environment within the nervous system to favor growth and development while simultaneously blocking pathways responsible for inflammation and neuron dysfunction [10].
Thymosin Alpha-1 for Reducing Blood Pressure
Recent research indicates that thymosin alpha-1 blocks angiotensin converting enzyme (ACE) and thus can reduce blood pressure.
Research has shown that the reduction of ACE reduces blood pressure by relaxing blood vessels. Inhibiting ACE can also reduce cardiac remodeling, slow the progression of atherosclerosis (plaque build up), and improve kidney function. It is hoped that thymosin alpha-1 may offer the benefits of ACE inhibition without the side effects commonly associated with currently available drugs [4].
Thymosin Alpha-1 for Weight Loss
Bioactive peptides have been used to treat metabolic disorders like type-2 diabetes and obesity for years. With the emergence of newer techniques for multifunctional peptides, mimetics, peptide analogs, and aptamers, there is a sudden revival in this therapeutic field [11].
Despite there being a lack of clinical data or any human trials as yet to evidence the effectiveness of thymosin alpha-1 in combating obesity, there is anecdotal evidence and speculation relating to its potential effectiveness in assisting with weight loss.
Thymosin Alpha-1 Side Effects
The side effects related to thymosin alpha-1 appear to be rare and relatively minimal—which is one of the principle benefits of the peptide.
Research has indicated that thymosin alpha-1 is well tolerated, while most studies observed only local irritation at the injection site [12]. Further, the peptide has been used for more than 40 years and has been shown to be safe by patients as well as having a low level of toxicity.
The lack of significant side effects reported with Thymosin-Alpha 1 is in sharp contrast to other major immune response modulators such as IFN and IL-2, which can lead to flu-like symptoms including malaise, fever, headache, chills and pulmonary edema (with IL-2).
Some rare side effects which have been observed with TA-1 include: Erythema, itching at the injection area, dry mouth, darkening of moles, increase of freckles, weight loss, increased hunger, and some drowsiness.
In clinical trials, thymalfasin (a synthetic TA-1 analog) when combined with interferon 2b, was reported to have rare side effects such as: fever, fatigue, muscle aches, nausea, vomiting, and neutropenia when compared to interferon-alpha 2b alone or with placebo [2].
It should be noted that the majority of the listed side effects are not directly related to the peptide itself per se, but are general potential side effects, which should be borne in mind when administering an injection of any type.
Thymosin Alpha-1 Dosage
For reference purposes, we relate a sample thymosin alpha-1 dosage protocol that may be administered to achieve inflammation reduction in subjects [2]:
Daily Dosage
500mcg of thymosin-alpha 1
Study Duration
Administer thymosin alpha-1 until inflammation in the subject’s affected area has subsided.
Notes
Administer thymosin alpha-1 via subcutaneous injection. One 10mg vial of thymosin alpha-1 represents a 20-day course of the above protocol.
