CSF - 1 receptor - regulated macrophage proliferation 1 Macrophage Proliferation is Regulated Through CSF - 1 Receptor

Background: Activation loop Y807F or juxtamembrane domain Y559F mutations compromise CSF-1 receptor-mediated macrophage proliferation. Results: Tyr-559 suppresses constitutive proliferative activity of Tyr-807; ligand-induced Tyr559 phosphorylation relieves this inhibition and activates pathways. Conclusion: Tyr-807 drives proliferation. Tyr-559 confers ligand dependence. Significance: How indi...

The Cbl protooncoprotein stimulates CSF-1 receptor multiubiquitination and endocytosis, and attenuates macrophage proliferation.

Colony-stimulating factor-1 (CSF-1) activation of the CSF-1 receptor (CSF-1R) causes Cbl protooncoprotein tyrosine phosphorylation, Cbl-CSF-1R association and their simultaneous multiubiquitination at the plasma membrane. The CSF-1R is then rapidly internalized and degraded, whereas Cbl is deubiquitinated in the cytoplasm without being degraded. We have used primary macrophages from gene-target...

Therapeutic applications of macrophage colony-stimulating factor-1 (CSF-1) and antagonists of CSF-1 receptor (CSF-1R) signaling.

Macrophage-colony stimulating factor (CSF-1) signaling through its receptor (CSF-1R) promotes the differentiation of myeloid progenitors into heterogeneous populations of monocytes, macrophages, dendritic cells, and bone-resorbing osteoclasts. In the periphery, CSF-1 regulates the migration, proliferation, function, and survival of macrophages, which function at multiple levels within the innat...

Macrophage colony-stimulating factor (CSF-1) enhances invasiveness in CSF-1 receptor-positive carcinoma cell lines.

We have identified two lung carcinoma cell lines, A549 and Calu-1, expressing low levels of the macrophage colony-stimulating factor (CSF-1) receptor (CSF-1R), encoded by the c-fms oncogene. The effect of CSF-1 on the invasive potential of these CSF-1R-positive tumor cell lines and on two other CSF-1R-bearing cell lines, the BT-20 breast carcinoma cell line and the CSF-1 growth-dependent murine...

Colony-stimulating factor-1 (CSF-1) receptor-mediated macrophage differentiation in myeloid cells: a role for tyrosine 559-dependent protein phosphatase 2A (PP2A) activity.

M1 myeloid cells transfected with the wild-type (WT) colony-stimulating factor-1 (CSF-1) receptor (CSF-1R; M1/WT cells) undergo CSF-1-dependent macrophage differentiation. By mutation studies, we have provided prior evidence that tyrosine 559 in the CSF-1R cytoplasmic domain governs the Src-dependent differentiation pathway. Further components of this pathway were then sought. We report that th...
