摘要: Crohn's disease (CD) is a chronic inflammatory associated with dysregulated T cell response towards intestinal microflora. Vitamin D has immune modulatory effects on cells through the nuclear vitamin receptor (VDR) in vitro. It unclear how oral treatment affects VDR expression. The aim of this study was to establish flow cytometry protocol, including and cytoplasmic expression, investigate expression CD patients. protocol for staining developed using human acute monocytic leukaemia line (THP-1). evaluated anti-CD3/CD28-stimulated peripheral blood mononuclear (PBMCs) from D3- (n = 9) placebo-treated Anti-VDR-stained PBMCs were examined by cytometry, their cytokine production determined bead array. VDR, CYP27B1 RXRα mRNA levels CD4(+) measured quantitative reverse transcriptase polymerase chain reaction. enabled detection results confirmed confocal microscopy supported correlation increased following stimulation. This up-regulation inhibited 30% compared placebo patients (P 0027). correlated in-vitro interferon-γ stimulated 0.01). Flow useful method which measure intracellular reduces receptor-mediated up-regulation.
