Interleukin

Interleukin-2 (IL-2) is a protein produced by immune cells, particularly T-cells, that plays a vital role in the body's immune response. It helps stimulate the growth and activity of T-cells, which are essential for fighting infections and diseases. IL-2 enhances the body's ability to recognize and attack harmful substances like viruses and cancer cells. Due to its important functions, IL-2 is also used in certain medical treatments, particularly for cancer and autoimmune diseases, where boosting the immune response can be beneficial.
