Colony-stimulating factors, or CSFs, can be described as growth factors that trigger the clonal growth of hematopoietic progenitors. Although all CSFs tend to regulate myeloid cell numbers, each exhibits a level of specificity to its target cells and effects.
Researchers show more and more interest in targeting these CSFs in inflammatory and autoimmune disorders, as well as cancer.
The CSF family includes the following:
- Macrophage colony-stimulating factor (M-CSF/CSF1) that binds to the homodimeric CSF1 receptor (CSF1R/CD115) to control the proliferation, survival, differentiation and function of myeloid lineage cells. Modifications in CSF1R/CD115 have been related to cancer and Alzheimer’s disease.
- Granulocyte-macrophage colony-stimulating factor (GM-CSF/CSF2) that binds to the GM‑CSF receptor (GM-CSFR/CD116) — that contains an exclusive α‑chain (CSF2RA) and the common β subunit (CSF2RB/CD131) — to induce the maturation of stem cells and the differentiation of monocytes and granulocytes.
- Granulocyte colony-stimulating factor (G-CSF/CSF3) that binds to the homodimeric G-CSF receptor (G-CSFR/CD114) to trigger all cells in the granulocyte lineage. It has been linked to neutropenia, acute myeloid leukemia and bone marrow transplants.
- Multiple colony-stimulating factor or interleukin 3 (IL-3) that binds to the IL-3 receptor (IL-3R), which contains an exclusive α‑chain (IL3RA) paired with the common β subunit (CD131). The GM-CSF and IL-5 receptors share the common beta subunit. IL-3 induces the growth of immature progenitor cells of all myeloid lineages and has been linked to autoimmune diseases.
CSF family ligands and receptors
Sino Biological has come up with high-activity CSF ligand and receptor proteins from different species to help investigate the biology of CSFs and receptors. The company has also created various functional isoforms for them.
