Abstract

Neuroinflammation and microglial activation are significant processes in Alzheimer's disease pathology. Recent genome-wide association studies have highlighted multiple immune-related genes in association with Alzheimer's disease, and experimental data have demonstrated microglial proliferation as a significant component of the neuropathology. In this study, we tested the efficacy of the selective CSF1R inhibitor JNJ-40346527 (JNJ-527) in the P301S mouse tauopathy model. We first demonstrated the anti-proliferative effects of JNJ-527 on microglia in the ME7 prion model, and its impact on the inflammatory profile, and provided potential CNS biomarkers for clinical investigation with the compound, including pharmacokinetic/pharmacodynamics and efficacy assessment by TSPO autoradiography and CSF proteomics. Then, we showed for the first time that blockade of microglial proliferation and modification of microglial phenotype leads to an attenuation of tau-induced neurodegeneration and results in functional improvement in P301S mice. Overall, this work strongly supports the potential for inhibition of CSF1R as a target for the treatment of Alzheimer's disease and other tau-mediated neurodegenerative diseases.

  • [3H]PBR28 binding was significantly increased in the cortex, hippocampus and thalamus of ME7 vs. NBH mice.

    “[3H]PBR28 binding was significantly increased in the cortex, hippocampus and thalamus of ME7 vs. NBH mice, in line with previous findings [33, 37].”

    From Pharmacological modulation of TSPO in microglia/macrophages and neurons in a chronic neurodegenerative model of prion disease (2023) · cites this paper as [33]

    The Results section reports significantly increased TSPO signal in the hippocampus, somatosensory cortex and thalamus of ME7 versus NBH mice. However, the Methods section (TSPO autoradiography) identifies the ligand as [3H]PK11195, not [3H]PBR28. The regional finding is supported, but the claim names the wrong tracer. (LLM, conf=0.90)

  • Microglia are the principal driving force of neurodegeneration and tau pathogenesis in tauopathy mouse models.

    “We and others subsequently identified microglia as the principal driving force of neurodegeneration and tau pathogenesis in tauopathy mouse models (Mancuso et al., 2019; Shi et al., 2019).”

    From Overexpressing low‐density lipoprotein receptor reduces tau‐associated neurodegeneration in relation to apoE‐linked mechanisms (2021) · cites this paper as Mancuso et al., 2019

    The Discussion reports that inhibiting microglial proliferation in P301S mice prevented neurodegeneration and potentially slowed tau aggregation. It describes activated microglia as deleterious, but does not establish them as the principal driving force of either process across tauopathy mouse models; it explicitly notes uncertainty about whether their effect on tau pathology is predominant. The indexed passages provide section labels but no page numbers. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Studies using transgenic P301STau mice report that microglial depletion reduced neurodegeneration and the accumulation of phosphorylated tau.

    “In line with our findings, studies using transgenic P301STau mice report that microglial depletion reduced neurodegeneration and the accumulation of phosphorylated tau (Johnson et al., 2023; Mancuso et al., 2019; Shi et al., 2019).”
  • The selective CSF1R inhibitor JNJ527 significantly blocked microglial proliferation in the ME7 mouse model of prion disease, as detected by ex vivo autoradiography with [3H]PK11195.

    “We previously demonstrated that the selective CSF1R inhibitor JNJ527 significantly blocked microglial proliferation in the ME7 mouse model of prion disease, and this has been detected by ex vivo autoradiography with the first generation TSPO ligand, [3H]PK11195 [33].”
  • In the ME7 mouse, the selective CSF1R inhibitor JNJ527 significantly blocks microglial proliferation, as shown by reduced [3H]PK11195 binding on autoradiography.

    “Using the ME7 mouse, we previously corroborated the ability of the selective colony stimulating factor receptor 1 (CSF1R) inhibitor, JNJ-40346527 (JNJ527), to significantly block microglial proliferation. This was demonstrated by the reduced binding of the first generation TSPO tracer, [3H]PK11195, using autoradiography [33].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
