Adaptive immunity: Putting the work of B and T cells together The need for both innate and adaptive immunity: 1. T cells find their target (MHC/peptide) 2. Appropriate T cells are trapped in lymph tissue 3. Effector T cells leave nodes Which type of helper T cell will you become? Stimulate macrophages Stimulate B cells Antigen presentation affects T cell type: How do effector T cells find their target sites? Red = defense mechanism Yellow = protective immunity The immune response to mucosal invasion: Oral Tolerance: T cells involved Inflammatory response not induced Antigen not presented by M cells Immunological memory: Quantitative and qualitative changes
