MHC class II molecules are expressed by the professional antigen-presenting cells (APCs) of the immune system. APCs use MHC class II molecules to provide CD4-positive T cells with an overview of the surrounding tissue environment. These interactions are important for activating T cells during infec...
MHC (major histocompatibility complex) class II molecules are transmembrane glycoproteins expressed on the surface of professional antigen-presenting cells, such as macrophages, dendritic cells and B cells. Before their exposition on the cell surface, the MHC class II...
Answer to: Class I MHC molecules ___. a) activate B cells b)activate cytotoxic T cells c) are found only on antigen-presenting cells...
Before their exposition on the cell surface, the MHC class II molecules react with endocytosed exogenous antigens, which are then presented to the T cells. The antigen-binding grove between MHC class II alpha and beta chain is open at both ends and is 15-24 amino acid residues l...
MHC class II molecules expressed on the surface of specialized antigen presenting cells (APCs)2 function by presenting peptides derived from foreign protein antigens to specific CD4 T cells, a process that initiates and propagates immune responses (1). The interaction of MHC-II-peptide complexes ...
However, the Hp proteins that bind to class II MHC and trigger apoptosis are not known. Since urease is a major Hp product that stimulates cytokine secretion by class II MHC+ cells, we hypothesized that apoptosis in gastric epithelial cells is signaled through class II MHC molecules subsequent ...

Staphylococcal enterotoxin B and toxic shock syndrome toxin-1 bind to distinct sites on HLA-DR and HLA-DQ molecules. Staphylococcal enterotoxins (SE) activate human T cells in vitro. This requires the presence of Ia+ accessory cells but does not require processing of the toxin by the accessory...
