Figure Lengend Snippet: Expression and activation of STAT1 in mouse lung tissues. ( A ) mRNA expression levels of STAT1 in the lung tissues of mice across the uninfected control, the infection control, and the treatment groups. ( B ) Protein expression levels of p-STAT1 in the uninfected control, the infection control, and the treatment groups of mice. Data are shown as mean ± standard error of the mean, n = 3. Hashtags (#) represent the infection control group compared to the uninfected control group, and asterisks (*) represent the infection control group compared to the corresponding treatment group (* P < 0.05, ** P < 0.01, and ### P < 0.001).

Article Snippet: The membrane was blocked with TBST buffer (G2150, Servicebio Technology Co., Ltd. Wuhan, China) containing 5% bovine serum albumin and then incubated with primary antibody STAT1 (1:1,000, #9172T, Cell Signaling Technology, MA, USA), p-STAT1 (1:1,000, #7649T, Cell Signaling Technology, MA, USA), and β-actin (1:10,000, AC004, Abclonal, Wuhan, China) overnight at 4°C.

Article Title: Selective JAK Inhibition Reveals Paradoxical and Hierarchical Control of interferon-γ-driven Autoimmunity in AIRE Deficiency

doi: 10.64898/2026.03.05.709894

Figure Lengend Snippet: Untreated Air e −/− mice and Air e −/− mice treated for four weeks with selective JAK1i, JAK2i, or JAK3i were analyzed. Lungs were processed for intracellular cytokine staining, qPCR, ELISA, and immunoblot analyses. ( A-B ) Representative flow cytometry plots showing IFN-γ production by CD4 + and CD8 + T cells. ( C-D ) Frequency (of total CD4 + and CD8 + T cells) and absolute numbers of IFN-γ + CD4 + and IFN-γ + CD8 + T cells in the lung. ( E-F ) Relative Ifng mRNA expression and IFN-γ protein concentrations in lung homogenates. ( G ) Relative Stat1 mRNA expression. ( H ) Representative immunoblots of phospho-STAT1 (pSTAT1), total STAT1, and GAPDH. ( I-J ) Quantification of total STAT1 and phospho-STAT1 normalized to GAPDH. For IFN- γ + CD4 + and IFN-γ + CD8 + T cells: n = 9-14 mice per group from four independent experiments. For Ifng and Cxcl9 mRNA: n = 15-22 mice per group from four independent experiments. For Stat1 _mRNA: n = 10-17 mice per group from three independent experiments. For CXCL9 protein: n = 5-10 mice per group from two independent experiments. For STAT1 and pSTAT1 immunoblots: n = 15-22 mice per group from four independent experiments). Statistical analyses were performed using one-way ANOVA or Kruskal-Wallis test with Dunn’s multiple comparisons to the untreated Air e −/− mice. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001.

Article Snippet: Primary antibodies against GAPDH (catalog no. 5174S), STAT1 (catalog no. 14995S), and pSTAT1 (catalog no. 9167S) (Cell Signaling Technologies, USA) were used at 1:1,000 dilution, with HRP-conjugated anti-rabbit IgG conjugated with HRP (catalog no.7074S; Cell Signaling Technology) as the secondary antibody.
