Protein Description
Interleukin-3 (IL-3) is belongs to hematopoietic growth factors. It is a secreted protein. IL-3 can improve the body's natural response to disease as part of the immune system.  IL-3 stimulates the differentiation of multipotent hematopoietic stem cells into myeloid progenitor cells (as opposed to lymphoid progenitor cells where differentiation is stimulated by IL-7) as well as stimulates proliferation of all cells in the myeloid lineage (erythrocytes, megakaryocytes, granulocytes, monocytes, and dendritic cells) in conjunction with other cytokines, such as EPO, GM-CSF, TPO and IL-6. Additionally, IL-3 aids in embryo implantation and placental development, was found to be decreased both in pregnant women with antiphospholipid syndrome and in animal models of APS. IL-3 also participates in the response of the organism to various types of stress.
