متن کاملClass II major histocompatibility complex molecule expression on murine eosinophils activated in vivo by Brugia malayi.
The Th-2 response to microfilariae of Brugia malayi in BALB/c mice is associated with peritoneal eosinophilia. These eosinophils had an activated hypodense phenotype in vivo and expressed high levels of the class II major histocompatibility complex (MHC). Interleukin 4 up-regulated the class II MHC, whereas gamma interferon inhibited class II MHC expression on eosinophils.
متن کاملProcessing and major histocompatibility complex class II presentation of Legionella pneumophila antigens by infected macrophages.
To better understand interactions between the intracellular pathogen Legionella pneumophila and macrophages (Mphis), host and bacterial determinants important for presentation of antigens on major histocompatibility complex class II molecules (MHC-II) were investigated. It was determined that immune CD4 T-cell responses to murine bone marrow-derived Mphis (BMphis) infected with wild-type L. pne...
متن کاملMacrophages escape inhibition of major histocompatibility complex class I-dependent antigen presentation by cytomegalovirus.
The mouse cytomegalovirus (MCMV) m152- and m06-encoded glycoproteins gp40 and gp48, respectively, independently downregulate major histocompatibility complex (MHC) class I surface expression during the course of productive MCMV infection in fibroblasts. As a result, presentation of an immediate-early protein pp89-derived nonapeptide to H-2L(d)-restricted CD8(+) cytotoxic T cells is completely p...
متن کاملCytokines Regulate Proteolysis in Major Histocompatibility Complex Class II–Dependent Antigen Presentation by Dendritic Cells
Endo/lysosomal proteases control two key events in antigen (Ag) presentation: the degradation of protein Ag and the generation of peptide-receptive major histocompatibility complex (MHC) class II molecules. Here we show that the proinflammatory cytokines tumor necrosis factor alpha and interleukin (IL)-1beta rapidly increase the activity of cathepsin (cat) S and catB in human dendritic cells (D...
