Antigen Presentation to B Cells
Trends in Immunology, 2016Unlike T cells that recognize digested peptides, B cells recognize their cognate antigen in its native form. The B cell receptor used in recognition can also be secreted to bind to antigens and initiate multiple effector functions such as phagocytosis, complement activation, or neutralization of receptors.

Current Opinion in Immunology, 1993
Different antigen-presenting cells elicit responses in different T-cell populations for primary activation, secondary stimulation and cytotoxic effector functions. Maturing bone marrow derived dendritic cells may acquire and process antigens, transport them to lymph nodes and activate naive T cells located there. By contrast, follicular dendritic cells,

Cell biology of antigen presentation
Current Opinion in Immunology, 1993MHC class I molecules present degradation products derived from intracellular proteins, whereas MHC class II molecules generally present peptides derived from extracellular or surface proteins. Recent insights into the cell biology of MHC class I and II molecules explain this difference.

Antigen presentation, antigen-presenting cells and antigen processing
Current Opinion in Immunology, 1988To summarize, during the period under review there have been considerable advances in our understanding of how antigen is associated with MHC on the surface of a presenting cell. Basic rules which govern this association have been confirmed as including both the nature and the configuration of the antigen.

1985
Three major issues were discussed in the workshop: (1) the role of antigen processing in T-cell activation and situations in which it may not be necessary for T-cell stimulation, (2) the differences in antigen presenting function of macrophages and dendritic cells and the ability of dendritic cells to process antigen, and (3) the role of the type of ...

Antigen-presenting cells in allergy
Journal of Allergy and Clinical Immunology, 2001The complex interaction of the innate and adaptive immune system requires flexibility and cooperation among various cell types. In this regard, antigen-presenting-cells (APCs) play a pivotal role in transferring information from the periphery of the organism to lymphoid organs, where they initiate the activation of naive T cells.

Antigen-Presenting Cells in the Skin
Annual Review of Immunology, 2017Professional antigen-presenting cells (APCs) in the skin include dendritic cells, monocytes, and macrophages. They are highly dynamic, with the capacity to enter skin from the peripheral circulation, patrol within tissue, and migrate through lymphatics to draining lymph nodes.

Are the Mast Cells Antigen Presenting Cells?
Immunological Investigations, 1989Mast cells have an important role in allergic reactions secreting histamine and other mediators of immediate hypersensitivity. In the present study we evaluated major histocompatibility complex (MHC) class II antigen expression in mast cells and their possible role in antigen presentation.

Antigen presentation to B cells
Current Opinion in Immunology, 1991B lymphocytes encounter antigen within the body, which causes them to undergo clonal expansion, affinity maturation and differentiation to antibody-forming cells. How they come into contact with the immunogen, and the subsequent response induced is the subject of several recent reports.

Antigen‐presenting Cells for CD8+ T Cells
Immunological Reviews, 1990Evidence is presented that a wide variety of cell types are capable of presenting class I alloantigens to purified unprimed CD8+ cells in the absence of added help. These cells include dendritic cells, a population of Ia- Thy 1- cells in spleen, peritoneal exudate cells and one of three T-tumor lines. Some cell types, e.g.
