Figure Lengend Snippet: IRF1 drove Zbp1 transcription in microglia. ( A ) Heatmap showing TF activity scores (right) and fold-change expression (left) associated with PANoptosis activity in microglia. ( B ) UMAP visualization of transcriptional activity scores (top) and gene expression levels (bottom) of Nr1d1, Spi1, Myc, Irf1 , and Cebpd across all cell types. ( C ) Heatmap showing the results of Pearson’s correlation analysis between Nr1d1, Spi1, Myc, Irf1 , and Cebpd and PANoptosis activity scores. ( D ) Bar graph showing the inferred TF activity at bulk RNA-seq levels. ( E ) The IGV browser illustrating the potential regulatory relationship between NR1D1, SPI1, MYC, IRF1, and CEBPD and the Zbp1 promoter region. ( F ) UCSC Genome Browser showing a distinct IRF1 binding peak within the Zbp1 promoter region, based on public ChIP-seq data. ( G ) Immunofluorescence at 7 days after SCI showing nuclear translocation of IRF1 (red) in Iba1+ microglia (green); nuclei were counterstained with DAPI (blue). Scale bars, 20μm (n=4 rats per group). ( H ) WB analysis of IRF1 and ZBP1 protein expression of microglia in vitro. Vinculin was used as a loading control. *, p<0.05; ****, p<0.0001.
