Article Title: Microglial pyroptosis drives neuropathic pain and targeting NLRP3 alleviates pain and neuroinflammation.
Article Snippet: Neuropathic pain is triggered by nerve damage or disease and involves chronic neuroinflammation driven by activated microglia releasing pro-inflammatory cytokines..

( B ) Flow cytometry was used to evaluate the viability of LPS-stimulated and unstimulated Nogo-B fl/fl and Nogo-B mko BMDMs. ( C ) Western blotting was performed to evaluate p-RIPK3, RIPK3, p-MLKL, MLKL, C-caspase-1, and Caspase-1 expression in LPS-stimulated and unstimulated Nogo-B fl/fl and Nogo-B mko BMDMs. ( D ) Liver sections from the mice were subjected to p-RIPK3 and p-MLKL IHC analysis. ( E ) The proportions of p-RIPK3-positive and p-MLKL-positive regions were quantified. ( F ) Western blotting was used to evaluate p-RIPK3, RIPK3, p-MLKL, MLKL, C-caspase-1, and Caspase-1 expression in the liver tissues of the mouse liver fiber models. ( G ) Western blotting was used to evaluate p-RIPK3, RIPK3, p-MLKL, MLKL, C-caspase-1, and Caspase-1 expression. ( H ) Flow cytometry was conducted to evaluate the cell viability of LPS-triggered Nogo-B mko BMDMs after Lv-RIPK3 or RIPK3-IN-4 transfection. The data are presented as the means ± SEMs; n = 6 per group; original magnification, 10×; scale bars, 200 μm; ∗∗ P < .01, ∗∗∗ P < .001, ∗∗∗∗ P < .0001.

The adoptive transfer of BMDMs revealed that the Nogo-B/RIPK3 axis promoted NLRP3 inflammasome activation in macrophages and accelerated liver fibrosis. ( A ) Schematic illustration of adoptive transfer of BMDMs from mice. ( B ) ALT and AST levels in the serum of mice. ( C ) liver sections from mice subjected to Masson staining, Sirius Red staining, and α-SMA IHC analysis (original magnification 10×; scale bars, 200 μm). ( D ) Collagen I and α-SMA mRNA expression in murine livers was examined through qRT-PCR. ( E ) mRNA expression of IL-1β, TNF-α, IL-6, and IL-10 was quantified in liver tissues. ( F ) Protein expression of ASC, NLRP3, Pro-IL-1β, and IL-1β was measured via Western blotting in liver tissues. Data are presented as the means ± SEMs; n = 6 per group; ∗∗ P < .01. ∗ P < .05.

Differences in Nogo-B + RIPK3 + macrophage populations within liver tissue after adoptive transfer of BMDMs. ( A ) Western blotting was used to evaluate the levels of p-RIPK3, RIPK3, p-MLKL, MLKL, C-caspase-1, and Caspase-1 in liver tissues. ( B–D ) Multiplex IF microscopy demonstrated triple colocalization of the macrophage markers F4/80 ( yellow ), Nogo-B ( green ), and RIPK3 ( red ) in fibrotic liver sections from mice receiving BMDMs in 3 independent models: ( B ) CCl 4 -induced, ( C ) BDL-induced, and ( D ) MCD-induced fibrosis. Nuclei were counterstained with DAPI ( blue ). n = 6 per group; original magnification, 20×; scale bars, 100 μm.
