CSF-1R
Phase Ib study of the combination of pexidartinib (PLX3397), a CSF-1R inhibitor, and paclitaxel in patients with advanced solid tumors
14 views | Aug 03 2019
Wesolowski R et al. showed the combination of pexidartinib and paclitaxel was generally well tolerated. RP2D for pexidartinib was 1600 mg/day. Pexidartinib blocked CSF-1R signaling, indicating potential for mitigating macrophage tumor infiltration. [Read the Full Post]
Sustained inhibition of receptor tyrosine kinases and macrophage depletion by PLX3397 and rapamycin as a potential new approach for the treatment of MPNSTs
12 views | Jul 18 2019
Patwardhan PP et al. suggested that PLX3397 is superior to imatinib in the treatment of MPNSTs, and the combination of PLX3397 with a TORC1 inhibitor could provide a new therapeutic approach for the treatment of this disease. [Read the Full Post]
Inhibition of colony-stimulating-factor-1 signaling in vivo with the orally bioavailable cFMS kinase inhibitor GW2580
27 views | Jun 04 2019
Conway JG et al. showed that GW2580's selective inhibition of monocyte growth and bone degradation is consistent with cFMS kinase inhibition. The ability of GW2580 to chronically inhibit CSF-1 signaling through cFMS kinase in normal and tumor cells in vivo makes GW2580 a useful tool in assessing the role of cFMS kinase in normal and disease processes.

Microglial modulation through colony-stimulating factor-1 receptor inhibition attenuates demyelination
65 views | Feb 25 2019
Wies Mancini VSB et al. showed that BLZ945 induced a significant reduction in the number of microglia. Preventive BLZ945 treatment attenuated demyelination in the acute CPZ model, mainly in cortex and external capsule. In contrast, BLZ945 treatment in the acute CPZ model failed to protect myelin or foster remyelination in myelin-rich areas, which may respond to a loss in microglial phagocytic capacity and the consequent impairment in oligodendroglial differentiation. Preventive and therapeutic BLZ945 treatment promoted remyelination and neuroprotection in the chronic model. These results could be potentially transferred to the treatment of progressive forms of MS. [Read the Full Post]
The c.1085A>G Genetic Variant of CSF1R Gene Regulates Tumor Immunity by Altering the Proliferation, Polarization, and Function of Macrophages
128 views | Nov 26 2018
Yeh YM et al. indicated that CSF1R c.1085A>G genetic variant regulates tumor immunity by altering the polarization and function of macrophages. This genetic variant confers the sensitivity to CSF-1R inhibitors, implying as a biomarker in targeting CSF-1R signaling for cancer treatment. [Read the Full Post]
Targeting Suppressive Myeloid Cells Potentiates Checkpoint Inhibitors to Control Spontaneous Neuroblastoma

Mao Y et al. demonstrated the essential role of CSF-1R signaling during the induction of suppressive myeloid cells and emphasize its clinical potential as an immunotherapy for human cancers. [Read the Full Post]

Heterogeneity of macrophage infiltration and therapeutic response in lung carcinoma revealed by 3D organ imaging
828 views | Sep 30 2017
Cuccarese MF et al. revealed that TAM density was heterogeneous across tumours in the same animal, overall TAM density is different among separate pulmonary tumour models, nanotherapeutic drug delivery correlated with TAM heterogeneity, and successful response to CSF-1R blockade is characterized by enhanced TAM penetration throughout and within tumours.

Neurotoxic reactive astrocytes are induced by activated microglia
853 views | Sep 26 2017
Liddelow SA et al. help to explain why CNS neurons die after axotomy, strongly suggest that A1 astrocytes contribute to the death of neurons and oligodendrocytes in neurodegenerative disorders, and provide opportunities for the development of new treatments for these diseases. [Read the Full Post]
