Serum Thymic Factor plays a crucial role in regulating immune function. It is primarily used in research and therapeutic applications to enhance immune responses, particularly in individuals with compromised immunity. The factor is studied for its potential in treating autoimmune diseases, as it helps maintain immune balance by modulating T-cell activity. Additionally, it is explored for its anti-aging properties, as it supports thymus function, which tends to decline with age. In clinical settings, it may be used to boost recovery in patients undergoing treatments that weaken the immune system, such as chemotherapy. Its application in immunotherapy is also being investigated for conditions like chronic infections and certain cancers.
