Description : CSF1R is a member of the type III subfamily of receptor tyrosine kinases that also includes receptors for SCF and PDGF. These receptors each contain five immunoglobulin-like domains in their extracellular domain (ECD) and a split kinase domain in their intracellular region (1-4). M-CSF receptor is expressed primarily on cells of the monocyte/macrophage lineage, dendritic cells, stem cells and in the developing placenta (1). Human M-CSF receptor cDNA encodes a 972 amino acid (aa) type I membrane protein with a 19 aa signal peptide, a 493 aa extracellular region containing the ligand-binding domain, a 25 aa transmembrane domain and a 435 aa cytoplasmic domain. The human M-CSF R ECD shares 60%, 64%, 72%, 75%, 75% and 76% aa identity with mouse, rat, bovine, canine, feline and equine M-CSF R, respectively. Activators of protein kinase C induce TACE/ADAM17 cleavage of the M-CSF receptor, releasing the functional ligand-binding extracellular domain (5). M-CSF binding induces receptor homodimerization, resulting in transphosphorylation of specific cytoplasmic tyrosine residues and signal transduction (6). The intracellular domain of activated M-CSF R binds more than 150 proteins that affect cell proliferation, survival, differentiation and cytoskeletal reorganization. Among these, PI3Kinase, P42/44 ERK and c-Cbl are key transducers of M-CSF R signals (3, 4). M-CSF R engagement is continuously required for macrophage survival and regulates lineage decisions and maturation of monocytes, macrophages, osteoclasts and DC (3, 4). M-CSF R and integrin alpha v beta 3 share signaling pathways during osteoclastogenesis and deletion of either causes osteopetrosis (7, 8). In the brain, microglia expressing increased
M-CSF R are concentrated with Alzheimers a beta peptide, but their role in pathogenesis is unclear (9, 10).

Ask a question
Are there any FDA-approved drugs targeting CSF1R for clinical use? 07/20/2021

Yes, drugs like pexidartinib have been approved for the treatment of certain rare tumors called tenosynovial giant cell tumors (TGCT) that overexpress CSF1R.

How can CSF1R inhibitors impact the tumor microenvironment? 10/22/2018

CSF1R inhibitors can modulate the tumor microenvironment by reducing the number of tumor-associated macrophages and promoting an anti-tumor immune response.

Can CSF1R inhibitors be used in combination with other cancer treatments? 09/20/2018

Yes, CSF1R inhibitors are often used in combination with chemotherapy and immunotherapy to enhance treatment effectiveness.

What are the potential clinical applications of CSF1R inhibitors? 01/21/2017

CSF1R inhibitors are being investigated for cancer therapy to block tumor-promoting macrophages and slow down cancer progression.

Can CSF1R inhibitors be used to treat neurodegenerative diseases? 12/04/2016

Research is ongoing, and CSF1R inhibitors are being explored as a potential therapy for neurodegenerative diseases, but no FDA-approved treatments currently exist.
