STAT phosphorylation in response to IL-6 stimulation. (A) Percentage of classical monocytes in FBM and ABM expressing pSTAT1 after IL-6 stimulation. (B) Percentage of pSTAT3⁺ classical monocytes in FBM and ABM. (C) Percentage of pSTAT5⁺ in classical monocytes in FBM and ABM. Cells were stimulated with 70 ng/mL IL-6. All data are from 2 or more experiments; n = 8 (total from all experiments).
