Figure Lengend Snippet: Constitutive expression of TSLP system in human lung macrophages (HLMs). The constitutive expression of sfTSLP, lfTSLP, TSLPR and IL-7Rα mRNAs was evaluated by quantitative RT-PCR in highly purified HLMs (4.5 × 10 6 cells/well) ( A ). Data are mean ± SD of 6 independent experiments obtained from different patients. Cytocentrifuge preparations of HLMs were immunohistochemically stained for TSLP ( C ), TSLPR ( D ), and IL-7Rα ( E ) with specific primary antibodies or in absence ( B ) of primary antibody (CTRL) as described in Materials and Methods. Microscope magnification 60×. Results are representative of 6 independent experiments obtained from different patients. * p < 0.01 when compared to lfTSLP, TSLPR, IL-7Rα. px: pixels.
