Interleukin 3
Interleukin 3 (IL-3) is a type of interleukin, a group of cytokines expressed by leukocytes. IL-3 is produced by T cells following cell activation by antigens, and it is known for its role in regulating blood cell production.
Function[edit]
IL-3 stimulates the differentiation of multipotent hematopoietic stem cells into myeloid progenitor cells or, with other factors like erythropoietin, into erythrocyte precursors. It is also involved in the maturation of mast cells.
Clinical Significance[edit]
Due to its role in blood cell production, IL-3 has potential therapeutic applications in diseases such as anemia and neutropenia. It is also being studied for its role in allergic responses due to its involvement in mast cell maturation.
Structure and Properties[edit]
IL-3 is a monomeric glycoprotein with a four-α-helical bundle structure. It is part of the hematopoietin family of cytokines and binds to the IL-3 receptor to exert its effects.
