Expert Answer 100% (1 rating) Previous question Next question An antigen-presenting cell (APC) or accessory cell is a cell that displays antigen complexed with major histocompatibility complexes (MHCs) on their surfaces; this process is known as antigen presentation. T cells may recognize these complexes using their T cell receptors (TCRs). APCs process antigens and present them to T-cells. Only the antigen-presenting cells involved in antigen processing and presentation by MHC class II molecules.

Antigen Presenting Cells - Few basic differencesThis video is about basic differences among antigen presenting cells ( Macrophage, Dendritic cell and Follicu Dendritic cells are immune cells that process antigen material; they are present in the skin (Langerhans cells) and the lining of the nose, lungs, stomach, and intestines. Sometimes a dendritic cell presents on the surface of other cells to induce an immune response, thus functioning as an antigen-presenting cell.

Antigen, substance that is capable of stimulating an immune response, specifically activating lymphocytes, which are the body’s infection-fighting white blood cells. Upon encountering their cognate antigen on SSMs, B cells become less motile and more dendritic. Macrophages: Macrophages are usually found in a … groups have shown that antigen-specific B cells can directly bind to their Antigen Presenting Cells Antigen-presenting cells (APCs) are specialized cells, which include macrophages, B lymphocytes, and dendritic cells, are distinguished by two properties: (1)they express class II MHC molecules on their membranes, and (2)they are able to deliver a co-stimulatory signal that is necessary for TH-cell activation. 1.
