interleukin-3 (IL-3)

Interleukin-3 (IL-3) is a protein, called a cytokine, that plays a key role in the immune system. It is produced mainly by white blood cells and acts as a messenger, signaling the bone marrow to produce and mature various blood cells like white blood cells, red blood cells, and platelets. IL-3 helps coordinate the body's response to infections, inflammation, and injuries by supporting the growth and development of these blood cells. It is essential for maintaining a healthy balance of blood components and supporting immune function.
