Abstract:
AIM: To explore the influence of CD47 molecules on the maturation and function of cultured dendritic cells (DCs). METHODS: Monocyte cell-derived DCs were propagated in granulocyte-macrophage colony-stimulating factor (GM-CSF) and lipopolysaccharide (LPS) plus interleukin (IL)-4, in the presence or absence of anti CD47 monoclonal antibodies (anti-CD47 mAbs). Flow cytometry was used to detect the cell surface phenotype. The concentration of IL-12P70 in supernatant was measured by ELISA technique. The antigen-presenting functions of DCs were determined in one-way mixed leukocyte reaction by Brdu-ELISA. Electrophoretic mobility shift assays (EMSA) was used to examine NF-?B activity. RESULTS: The anti-CD47 mAbs markedly suppressed the expression of CD80,CD86,CD83,CD1a,HLA-DR on the surface of DCs (P
