Antigen presentation to B cells
B cells are capable of mounting responses to a bewildering range of potentially pathogenic antigens through the production of high-affinity antibodies and the establishment of immunological memory. Thus, regulated B-cell activation is critical for protection against a variety of bacterial and viral infections, as well as cancers. Here, we discuss a number of recent imaging studies that have pro...
متن کاملMajor histocompatibility complex-restricted antigen presentation to antigen-reactive T cells by B lymphocyte tumor cells
Previous reports have demonstrated that accessory cells function to present soluble protein antigens in association with gene products encoded within the I region of the major histocompatibility complex (MHC) to antigen-reactive T helper cells. The biochemical events that occur during antigen presentation are, however, not well-documented primarily because of the difficulties involved in purify...
متن کاملAutoimmune myocarditis does not require B cells for antigen presentation.
T cells constitute the pathogenic effector cell population in autoimmune myocarditis in BALB/c mice. Using mice rendered deficient for B cells by a targeted disruption to the IgM transmembrane domain or by treatment with anti-IgM Ab from birth, we asked whether B cells are a critical APC in the induction of autoimmune myocarditis. B cell-deficient mice immunized with cardiac myosin develop myoc...
متن کاملAntigen 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 کاملAntigen presentation by resting B cells. Radiosensitivity of the antigen-presentation function and two distinct pathways of T cell activation
In this report we have examined the ability of small resting B cells to act as antigen-presenting cells (APC) to antigen-specific MHC-restricted T cells as assessed by either T cell proliferation or T cell-dependent B cell stimulation. We found that 10 of 14 in vitro antigen-specific MHC-restricted T cell clones and lines and three of four T cell hybridomas could be induced to either proliferat...
