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 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.

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.

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‐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.

Antigen-presenting cells for unprimed T cells
Immunology Today, 1989The triggering requirements of T cells differ for primed and unprimed cells: primed T cells can be triggered to produce lymphokines without viable antigen-presenting cells (APCs), apparently by crosslinking the T-cell receptor (TCR). Unprimed T cells do, however, require viable APCs and here Jonathan Sprent and Mary Schaefer review what type of cells ...

Corneal Antigen-Presenting Cells
2007Corneal antigen-presenting cells (APCs) were thought to reside exclusively in the peripheral cornea. However, recent evidence demonstrates that the central cornea is also endowed with a heterogeneous population of bone marrow-derived cells, including epithelial Langerhans cells (LCs) and anterior stromal dendritic cells (DCs), which under certain ...

Epithelial cell antigen presentation
Current Opinion in Gastroenterology, 2000For decades intestinal epithelial cells were thought of as passive barriers to luminal contents, cells involved in nutrient absorption and electrolyte secretion. Studies during the past 10 to 15 years have changed that concept as our understanding of mucosal immunity has evolved and as we have come to understand that the regulation of this system is ...

Antigen-Presenting Cells in the Decidua
2005Maternal tolerance against fetal antigens is still one of the unsolved questions in pregnancy. Focusing on the various subsets of immune cells playing in concert with the human immune system, tolerance induction is nowadays often accredited to a specialized group of immune cells, the antigen-presenting cells (APC).

Antigen Presentation by Human Antigen‐Presenting Cells to Antigen‐Specific Xenogeneic Murine T Cells
Microbiology and Immunology, 1986AbstractSuccessful antigen presentation by xenogeneic human antigen‐presenting cells (APC) to stimulate the proliferation of antigen‐specific, keyhole limpet hemocyanin (KLH)‐specific, ovelbumin (OVA)‐specific, and purified protein derivative of Mycobacterium tuberculosis (PPD)‐specific murine T cells was observed.
