Not A Necessary Part Of The Cell-mediated Immune Response Antigen Presenting Cells Present Antigen To Helper T Cells Antigen Presenting Cells Activate Cytotoxic T Colls Helper T Cells Release Cytokines, Which In Turn Activate Cytotoxic T Cells. The T cell response to a soluble protein requires the processing of the native antigen by an antigen-presenting cell (APC) to a peptide containing an antigenic determinant, which is transported to and bound on the antigen-presenting cell surface, where it is subsequently recognized by the specific T cell in the context of the appropriate Ia molecule. A cell that breaks down antigens and displays their fragments on surface receptors next to major histocompatibility complex molecules. This presentation is necessary for some T lymphocytes that are unable to recognize soluble antigens.

An antigen presenting cell like dendritic cell is a part of adaptive immune system. When it encounters a harmful foreign antigen, it engulfs it via phagocytosis. The phagocytic vesicle fuses with the intracellular lysosome and here the antigen is broken into smaller fragments. Partial Question 23 05 1 pts Antigen presenting cells are necessary for which from BIOLOGY MISC at Blessing-Rieman College of Nursing & Health Sciences Antigen presentation is central to specific immunity. Extracellular antigens can bind to professional antigen presenting cells (APCs) (macrophage, dendritic cells, and B cells).
