AbstractThe number of LFs, BAFF+, TLR4+ and proliferation marker Ki67+ B cells in lung explants or resections from subjects with CF and normal controls was quantified by immunostaining. The role of CFTR in B cell activation and LF development was then examined in two independent cohorts of uninfected CFTR-deficient mice (Cftr -/-) and wild type controls. The number of lung LFs, B cells and BAFF+, CXCR4+, immunoglobulin G+ B cells was examined by immunostaining. Lung and splenocyte B cell activation marker and major histocompatibility complex class II (MHC class II) expression was quantified by flow cytometry. Inflammatory cytokine levels were measured in supernatants from isolated B cells from Cftr -/- and wild type mice stimulated in vitro with Pseudomonas aeruginosa lipopolysaccharide (LPS).
