Flow cytometry was performed to detect the frequency of CD8+PD-1+ (upper) and Ly6G+PD-L1 + or Ly6G+PD-L1− (lower) cells. P2RX1 expression was further determined in Ly6G+PD-L1+ and Ly6G+PD-L1− cells from WT mice ( n = 4 per group, three independent experiments). b Bone marrow neutrophils were isolated from WT and P2rx1 −/− mice and stimulated with tumor conditioned medium (TCM) or GM-CSF in the presence of a Nrf2 inhibitor or anti-GM-CSF neutralizing antibody. PD-L1 expression was detected by flow cytometry ( n = 4 per group, three independent experiments). c Integrative Genomics Viewer (IGV) was used to predict the two peaks that PD-L1 gene might be mediated by Nrf2 (upper). Bone marrow neutrophils were isolated from WT and P2rx1 −/− mice and stimulated with GM-CSF. Binding of PD-L1 gene by Nrf2 was detected by ChIP-PCR ( n = 3 per group, two independent experiments). d Bone marrow neutrophils were isolated from WT and P2rx1 −/− mice and stimulated with GM-CSF. Intracellular ROS was detected by flow cytometry ( n = 4 per group, three independent experiments). e Antigen activated CTLs was co-cultured with GM-CSF primed WT or P2rx1 −/− neutrophils. Cell proliferation was analyzed with CSFE staining in the presence or absence of anti-PD-1 neutralizing antibody ( n = 4 per group, three independent experiments). f KPC cells were transfected with empty lentiviral vector (KPC-LV) or OVA (KPC-OVA). Antigen-activated CTLs were co-cultured with KPC-LV or KPC-OVA cells in the presence of GM-CSF-primed WT or P2rx1 −/− neutrophils. Cytotoxicity was determined in the presence or absence of anti-PD-1 neutralizing antibody by counting the number of PI+ cells ( n = 4 per group, three independent experiments). Bars represent mean ± standard deviation in ( f ). P values are derived from one-way ANOVA and Tukey’s multiple comparisons test ( f ). Source data are provided as a Source data file.

    Figure Lengend Snippet: P2RX1 ablation restricts inflammatory responses in DSS-induced mouse colitis. (A) WT and P2rx1 −/− mice were treated with 2% DSS for 7 days. At days 0, 7, and 12, colon tissues were harvested, and RNA sequencing was performed. Differential analysis was analyzed, with P <0.001 and fold change >4 being considered as significantly varied (n = 3 for D0 P2rx1 −/− group, and n = 1 for the rest of the groups). (B) KEGG pathway analysis was performed to compare the functional enrichment genes of WT and P2rx1 −/− mice at day 7. (C) A heatmap of inflammation-associated genes was shown. (D) Inflammation-associated genes were detected by RT-qPCR (n = 4 per group). (E) Neutrophils and macrophages were analyzed by flow cytometry (n = 4 per group). **P < 0.01 and ***P < 0.001.

    Article Snippet: For P2RX1 staining, anti-P2RX1 (Alomone, APR-022, 1:80) antibody followed by an anti-rabbit-PE secondary antibody (Abcam, 1:200) was used.

    Intestinal microbiota is altered in DSS-treated P2rx1 −/− mice. (A) WT and P2rx1 −/− mice were treated with 2% DSS for 7 days. At days 0, 7 and 12, fecal microbiota was quantified using 16S rDNA sequencing. Principal component analysis (PCA) was performed based on the operational taxonomic units (OTUs) composition (n = 6 for D0 WT and P2rx1 −/− groups, n = 3 for the rest groups). (B) Relative abundance of bacterial phylum in the fecal microbiota was analyzed. (C) Detailed comparison of bacterial genus in WT and P2rx1 −/− mice was performed. (D) Functional metagenomics prediction analysis based on the result of 16S rDNA gene sequencing using PICRUSt1 was performed. (E) Fecal indole-3-acetic acid (IAA) and indole at day 7 were detected. IL-22 mRNA and protein at day 0 and day 7 were determined (n = 4 per group). **P < 0.01.

    Inhibition of P2RX1 promotes the efficiency of anti-TNF-α therapy in mouse colitis. (A, B) WT mice were treated with 2% DSS for 7 days. Anti-TNF-α monoclonal antibody (mAb) (0.1 mg/day) or/and P2RX1 inhibitor (NF449, 10 mg/kg/day) was/were administrated for 7 days. Weight loss (A) and disease activity index (DAI) (B) were calculated (n = 6 per group). Statistical analyses were performed at day 7. (C) At day 7, RT-qPCR was performed to detect inflammatory cytokine expression (n = 4 per group). (D) At day 7, colonic neutrophils were determined by cytometry (n = 4 per group). *P < 0.05, **P < 0.01, and ***P < 0.001.
