Differential cytokine/chemokine levels in BAL from ILD patients. A Human Cytokine Membrane Antibody Arrays were exposed to BAL from ILD patients and processed as per the manufacturer’s instructions. Images show representative membranes from each group of ILD patients. Black boxes denote positive internal controls and dashed black boxes denote negative internal controls. Representative cytokines with increased levels (red boxes) or decreased levels (blue boxes) in PLCH compared to SR-ILD or IPF are shown. B Schematic representation of the cytokine/chemokine spot positions on the membrane with respective internal controls. Rectangles filled with red background represents upregulated cytokines, and with blue background represents downregulated cytokines/chemokines in PLCH compared to SR-ILD or IPF
