Interleukin 3(IL-3) is aproteinthat inhumansis encoded by theIL3genelocalized on chromosome 5q31.1.[3][4]Sometimes also called colony-stimulating factor, multi-CSF, mast cell growth factor, MULTI-CSF, MCGF; MGC79398, MGC79399: after removal of the signal peptide sequence, the mature protein contains 133 amino acids in its polypeptide chain. IL-3 is produced as a monomer by activated T cells, monocytes/macrophages and stroma cells.[5]The major function of IL-3cytokineis to regulate the concentrations of various blood-cell types.[6]It induces proliferation and differentiation in both early pluripotentstem cellsand committedprogenitors.[7][8]It also has many more specific effects like the regeneration ofplateletsand potentially aids in early antibodyisotype switching.[9][10]

Function[edit]

Interleukin 3 is aninterleukin,a type of biological signal (cytokine) that can improve the body's natural response to disease as part of theimmune system.[10]In conjunction with other β common chain cytokinesGM-CSFandIL-5,IL-3 works to regulate the inflammatory response in order to clear pathogens by changing the abundance of various cell populations via binding at theinterleukin-3 receptor.[9][10]

IL-3 is mainly produced by activatedT cellswith the goal of initiating proliferation of various other immune cell types.[8]However, IL-3 has also been shown to be produced inIgG+B cellsand may be involved in earlier antibodyisotype switching.[9]IL-3 is capable of stimulating differentiation of immaturemyelomonocytic cellscausing changes to themacrophageandgranulocytepopulations.[8]IL-3 signaling is able to give rise to widest array of cell lineages which is why it has been independently named “multi-CSF” in some older literature.[10]

IL-3 also induces various effector functions in both immature and mature cells that more precisely modulate the body’s defense against microbial pathogens.[8][10]IL-3 is also involved in the reconstruction ofplateletsvia the development ofmegakaryocytes.[10]

Interleukin 3 stimulates the differentiation ofmultipotent hematopoietic stem cellsintomyeloid progenitor cellsor, with the addition of IL-7, intolymphoid progenitor cells.In addition, IL-3 stimulates proliferation of all cells in the myeloid lineage (granulocytes,monocytes,anddendritic cells), in conjunction with other cytokines, e.g.,Erythropoietin(EPO),Granulocyte macrophage colony-stimulating factor(GM-CSF), andIL-6.

IL-3 is secreted by basophils and activatedT cellsto support growth and differentiation ofT cellsfrom the bone marrow in an immune response. ActivatedT cellscan either induce their own proliferation and differentiation (autocrinesignaling), or that of otherT cells(paracrinesignaling) – both involveIL-2binding to theIL-2 receptoronT cells(upregulated upon cell activation, under the induction ofmacrophage-secretedIL-1). The human IL-3 gene encodes a protein 152 amino acids long, and the naturally occurring IL-3 is glycosylated. The human IL-3 gene is located onchromosome 5,only 9 kilobases from theGM-CSFgene, and its function is quite similar to GM-CSF.

Receptor[edit]

IL-3 is a T cell-derived, pluripotent and hematopoietic factor required for survival and proliferation of hematopoietic progenitor cells. The signal transmission is ensured by high affinity between cell surfaceinterleukin-3 receptorand IL-3.[11]This high affinity receptor contains α and β subunits. IL-3 shares the β subunit with IL-5 and granulocyte-macrophage colony-stimulating factor (GM-CSF).[12]This β subunit sharing explains the biological functional similarities of different hematopoietic growth factors.[13]

IL-3 receptors can be found on a variety of cell types including many immaturemyelomonocytic cellsin thehemopoietic systemsuch as hemopoietic progenitor cells, as well as certain myeloid progenitors,basophils,andeosinophils.[10]

IL-3/Receptor complex inducesJAK2/STAT5cell signalization pathway.[8]It can stimulate transcription factorc‑myc(activation of gene expression) andRas pathway(suppression of apoptosis).[5]

Discovery[edit]

In the early 1960s Ginsberg and Sachs discovered that IL-3 is a potent mast cell growth factor produced from activatedT cells.[11]Interleukin 3 was originally discovered in mice and later isolated from humans. The cytokine was originally discovered via the observation that it induced the synthesis of 20alpha-hydroxysteroid dehydrogenase in hematopoietic cells and termed it interleukin-3 (IL-3).[14][15]

Disease[edit]

IL-3 is produced by T cells only after stimulation withantigensor other specific impulses.

However, it was observed that IL-3 is present in the myelomonocytic leukaemia cell line WEHI-3B. It is thought that this genetic change is the key in development of this leukemia type.[6]

Immunological therapy[edit]

Human IL-3 was first cloned in 1986 and since then clinical trials are ongoing.[16]Post-chemotherapy, IL-3 application reduces chemotherapy delays and promotes regeneration ofgranulocytesandplatelets.However, only IL-3 treatment in bone marrow failure disorders such asmyelodysplastic syndrome(MDS) andaplastic anemia(AA) was disappointing.[13]

It has been shown that combination of IL-3, GM-CSF and stem cell factor enhances peripheral blood stem cells during high-dose chemotherapy.[17][18]

Other studies showed that IL-3 could be a future perspective therapeutic agent in lymphohematopoietic disorders and solid cancers.[19]

Interactions[edit]

Interleukin 3 has been shown tointeractwithIL3RA.[20][21]
