Targeting mi R‐155 restores abnormal microglia and attenuates disease in SOD 1 mice
Open accessAbstract
Objective: To investigate miR‐155 in the SOD1 mouse model and human sporadic and familial amyotrophic lateral sclerosis (ALS). Methods: NanoString microRNA, microglia and immune gene profiles, protein mass spectrometry, and RNA‐seq analyses were measured in spinal cord microglia, splenic monocytes, and spinal cord tissue from SOD1 mice and in spinal cord tissue of familial and sporadic ALS. miR‐155 was targeted by genetic ablation or by peripheral or centrally administered anti–miR‐155 inhibitor in SOD1 mice. Results: In SOD1 mice, we found loss of the molecular signature that characterizes homeostatic microglia and increased expression of miR‐155. There was loss of the microglial molecules P2ry12, Tmem119, Olfml3, transcription factors Egr1, Atf3, Jun, Fos, and Mafb, and the upstream regulators Csf1r, Tgfb1, and Tgfbr1, which are essential for microglial survival. Microglia biological functions were suppressed including phagocytosis. Genetic ablation of miR‐155 increased survival in SOD1 mice by 51 days in females and 27 days in males and restored the abnormal microglia and monocyte molecular signatures. Disease severity in SOD1 males was associated with early upregulation of inflammatory genes, including Apoe in microglia. Treatment of adult microglia with apolipoprotein E suppressed the M0‐homeostatic unique microglia signature and induced an M1‐like phenotype. miR‐155 expression was increased in the spinal cord of both familial and sporadic ALS. Dysregulated proteins that we identified in human ALS spinal cord were restored in SOD1 G93A/miR‐155−/− mice. Intraventricular anti–miR‐155 treatment derepressed microglial miR‐155 targeted genes, and peripheral anti–miR‐155 treatment prolonged survival. Interpretation: We found overexpression of miR‐155 in the SOD1 mouse and in both sporadic and familial human ALS. Targeting miR‐155 in SOD1 mice restores dysfunctional microglia and ameliorates disease. These findings identify miR‐155 as a therapeutic target for the treatment of ALS. ANN NEUROL 2015;77:75–99

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.
