Thymalin is a polypeptide that can be used for various dysfunctions within the immune system such as immune depression and infections caused by bacteria and viruses. Thymalin was first synthesized by researchers Morozov et. Al from the thymus of calves and has since shown promise in combating apoptosis and regulating regeneration and hematopoiesis. Additionally, the chemicals immunoprotective success is based on the restoration of T and B lymphocytes and the resulting increase in activity. In a study conducted by Khavinson et. Al, researchers examined the effects of thymalin as well as its peptide components, EW peptide, the dipeptide KE, and the tripeptide EDP.
In the study conducted, Khavinson et. Al found that the short peptide components EW, KE, and EDP were most likely to activate and differentiate the immune response, decrease rates of apoptosis, and increase the viability of immune cells.
