Efficient virus assembly, but not infectivity, determines the magnitude of hepatitis C virus-induced interferon alpha responses of plasmacytoid dendritic cells.
UNLABELLED Worldwide, approximately 160 million people are chronically infected with hepatitis C virus (HCV), seven distinct genotypes of which are discriminated. The hallmarks of HCV are its genetic variability and the divergent courses of hepatitis C progression in patients. We assessed whether intragenotypic HCV variations would differentially trigger host innate immunity. To this end, we st...
متن کاملEvaluation of Possible Role of Dendritic Cells in Various Lupus Nephritis
Background & Objectives: Chronicity of lupus nephritis (LN) should be considered for interaction of cell mediated immunity (CMI) and dendritic cells in glomeruli and tubulointerstitial areas. In this study establishment of immunohistopathological changes of dendritic cells and other immune effector cells in lupus nephritis comparing with non-lupus nephritis was performed. Materials & Methods: ...
متن کاملHuman plasmacytoid dendritic cells sense lymphocytic choriomeningitis virus-infected cells in vitro.
We previously reported that exosomal transfer of hepatitis C virus (HCV) positive-strand RNA from human Huh-7 hepatoma cells to human plasmacytoid dendritic cells (pDCs) triggers pDC alpha/beta interferon (IFN-α/β) production in a Toll-like receptor 7 (TLR7)-dependent, virus-independent manner. Here we show that human pDCs are also activated by a TLR7-dependent, virus-independent, exosomal RNA ...
متن کاملBlastic Plasmacytoid Dendritic Cell Neoplasm; A Report of Three Cases
Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare hematodermic myeloid malignancy that is known to be derived from plasmacytoid dendritic cells which are characterized by expression of CD4, CD56, and more specific markers such as CD123. Here, the authors present three cases of BPDCN diagnosed in the past two years and address different available diagnostic modalities such as morpho...
متن کاملHepatitis C Virus Stimulates Murine CD8α-Like Dendritic Cells to Produce Type I Interferon in a TRIF-Dependent Manner
Hepatitis C virus (HCV) induces interferon (IFN) stimulated genes in the liver despite of distinct innate immune evasion mechanisms, suggesting that beyond HCV infected cells other cell types contribute to innate immune activation. Upon coculture with HCV replicating cells, human CD141+ myeloid dendritic cells (DC) produce type III IFN, whereas plasmacytoid dendritic cells (pDC) mount type I IF...
