Effects of JAKi on JAK1/2 phosphorylation in IFN-γ stimulated neutrophils. Neutrophils were pretreated with JAKi (tofacitinib, baricitinib, upadacitinib) at the indicated concentrations for 1 h and then stimulated with IFN-γ (50 ng/ml) for 20 min. Phosphorylation of JAK1 (A) and JAK2 (B) were determined by Western blotting using phospho-specific antibodies against JAK1 and JAK2. Phosphorylation levels of JAK1 or JAK2 were normalized to total protein levels. For relative quantification, the ratio of phosphorylated JAK to total JAK was defined as 1.0 in the IFN-γ-stimulated neutrophils
