Antigen Presentation by Vascular Cells
Antigen presentation by cells of the vessel wall may initiate rapid and localized memory immune responses in peripheral tissues. Peptide antigens displayed on major histocompatibility complex (MHC) molecules on the surface of endothelial cells (ECs) can be recognized by T cell receptors on circulating effector memory T cells (TEM), triggering both transendothelial migration and activation. The ...
متن کاملIFN-gamma enables cross-presentation of exogenous protein antigen in human Langerhans cells by potentiating maturation.
We compared monocyte-derived dendritic cells and transforming growth factor-beta1-induced Langerhans-like cells (LCs) for their capacity to cross-present exogenous NY-ESO-1 protein/antibody immune complexes to an NY-ESO-1-specific CD8+ T cell clone. In contrast to dendritic cells, LCs were not able to cross-present NY-ESO-1 to the T cell clone constitutively but did so after treatment with IFN-...
متن کاملAntigen Presentation by MHC-Dressed Cells
Professional antigen-presenting cells (APCs) such as conventional dendritic cells (DCs) process protein antigens to MHC-bound peptides and then present the peptide-MHC complexes to T cells. In addition to this canonical antigen presentation pathway, recent studies have revealed that DCs and non-APCs can acquire MHC class I (MHCI) and/or MHC class II (MHCII) from neighboring cells through a proc...
متن کاملAntigen presentation by intestinal epithelial cells.
That's it, a book to wait for in this month. Even you have wanted for long time for releasing this book antigen presentation by intestinal epithelial cells; you may not be able to get in some stress. Should you go around and seek fro the book until you really get it? Are you sure? Are you that free? This condition will force you to always end up to get a book. But now, we are coming to give you...
متن کاملAntigen Presentation by Dendritic Cells In Vivo
Dendritic cells (DC) are heterogenous, comprising several subpopulations of migratory and lymphoid-organ-resident types. Recent studies addressing the role of each subset in antigen presentation in vivo have revealed a complex division of labor within the DC network. In addition to CD8(+) DC, migratory lung or dermal DC can cross-present antigen in vivo. Migratory DC also transport to the lymph...
