Immunology Exam 2 Study UAMS MLT- MLS | Latest Update | 2024/2025 | Graded A+ 1st recognizable B cell Pro-B cell A Memory B cell: -Requires protein antigen -Located in secondary follicles -Long life span -On subsequent contact with antigen:•Ability to respond rapidly & with greater intensity A T-cell that has class I MHC and comes in contact with a peptide and has a weak recognition, what does it become? it becomes a mature CD8 T-cell A T-cell that has class II MHC and comes in contact with a peptide and has a weak recognition, what does it become? it becomes a mature CD4 T-cell A T-cell that has no MHC and comes in contact with a peptide with a weak recognition, what does it become? the cell will die About how much of the bodies T-cells are CD4 2/3 About how much of the bodies T-cells are CD8 1/3 Acellular and Subunit Vaccines partial component, protein, or polysaccharides, from antigen that helps generate antibody response Activation of B memory cells with fast and large production of specialized antibodies Secondary immune response AGN-dependent lymphopoiesis Activated B-cell An Activated B Cell -Activation initiated by cross-linking; Antigen-dependent lymphopoiesis;Adjacent BCR bind to 2 or more antigen molecules;Serves to activate cell to proliferation & differentiation -Become plasma cells or memory cells Antibody-independent cytotoxicity? Natural Killer Cell attenuated vaccine most common; it contains the treated complete antigen that is no longer invective but can help generate antibody response B cell CD marker CD 45R Found on all hematopoietic cells; involved in activation B cell CD marker CD19 Signaling to regulate B cell development & activation B cell CD marker CD20 Thought to be involved in B cell activation B cell CD marker CD21 Receptor for complement
