Comparison of Several Maturation Inducing Factors in Dendritic Cell Differentiation

Background: Dendritic cells (DCs) are professional antigen presenting cells that have an important role in the initiation of immune response. The use of maturation factors in dendritic cell differentiation provides a promising approach in immunotherapy. Objective: In this study, we compared tumor necrosis factor-α, polyribocytidylic acid, lipopolysacharide and CpG oligonucleotides in inducing d...

Critical role of MHC class I-related chain A and B expression on IFN-alpha-stimulated dendritic cells in NK cell activation: impairment in chronic hepatitis C virus infection.

Dendritic cells (DCs) augment effector functions of NK cells, but the underlying mechanisms are not fully understood. Here we show in an in vitro coculture system that human monocyte-derived DCs enhance IFN-gamma production, CD69 expression, and K562 cytolytic ability of NK cells when DCs are prestimulated with various maturation stimuli such as IFN-alpha or LPS. Of interest is the finding that...

Immune interferon and leukocyte-conditioned medium induce normal and leukemic myeloid cells to differentiate along the monocytic pathway

Conditioned medium from phytohemagglutinin-stimulated human leukocytes contains a factor that can induce promyelocytic cell lines and certain acute myelogenous leukemia cells to differentiate along the monocytic pathway. In this report, we show that immature myeloid cells from normal bone marrow or the peripheral blood of patients with chronic myelogenous leukemia can be induced to differentiat...

Phenotypic and Functional Comparison between Flask Adherent and Magnetic Activated Cell Sorted Monocytes Derived Dendritic Cells

Background: Generation of an effective dendritic cell (DC) based cancer vaccine depends on appropriate differentiation of monocytes in vitro. Objective: To compare the effects of monocyte separation methods, flask adherence (Flask-DC) and magnetic activated cell sorting (MACS-DC), on phenotypic and functional characteristics of resultant DCs. Methods: DCs from healthy volunteers were generated ...
