Epithelioid glioblastoma with microglia features: Potential for novel therapy

28 views | Jul 28 2020

Nami Nakagomi et al. provided insight into the cellular nature of E-GBM and introduced several possibilities for effective targeted therapy for these patients. [Read the Full Post]

Early Long-Term Administration of the CSF1R Inhibitor PLX3397 Ablates Microglia and Reduces Accumulation of Intraneuronal Amyloid, Neuritic Plaque Deposition and Pre-Fibrillar Oligomers in 5XFAD Mouse Model of Alzheimer

55 views | May 22 2020

Justyna Sosna et al. demonstrate that CSF1R signaling, either directly on neurons or mediated by microglia, was crucial for the accumulation of intraneuronal amyloid and formation of neuritic plaques, suggesting that these two events were serially linked in a causal pathway leading to neurodegeneration and neuritic plaque formation.

Pexidartinib: First Approval

Yvette N Lamb et al. summarized the milestones in the development of pexidartinib leading to its first approval for TGCT. [Read the Full Post]

Cerebrospinal fluid penetration of the colony-stimulating factor-1 receptor (CSF-1R) inhibitor, pexidartinib

75 views | May 18 2020

Shankarappa PS et al. found that pexidartinib was well-tolerated in NHPs, with no Grade 3 or Grade 4 toxicities. The CSF penetration of pexidartinib after single-dose oral administration to NHPs was limited. [Read the Full Post]

Inhibition of colony-stimulating-factor-1 signaling in vivo with the orally bioavailable cFMS kinase inhibitor GW2580

0 views | Dec 25 2019

Conway JG et al. indicated 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.

Multicellular gene network analysis identifies a macrophage-related gene signature predictive of therapeutic response and prognosis of gliomas

114 views | Oct 08 2019

Sun X et al. identified macrophage-related gene signature has good prognostic value for predicting resistance to targeted therapeutics and survival of glioma patients, implying that combining current targeted therapies with new macrophage-targeted therapy may be beneficial for the long-term treatment outcomes of glioma patients.

Phase Ib study of the combination of pexidartinib (PLX3397), a CSF-1R inhibitor, and paclitaxel in patients with advanced solid tumors

191 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

173 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]

Microglial modulation through colony-stimulating factor-1 receptor inhibition attenuates demyelination

206 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]
