We will focus on adaptive responses. All these feature of an adaptive response require very specific interactions of molecules. Will describe B and T cells and their roles. Immunological memory - vaccination
The important difference between B and T cells is how they can recognize antigens.
• Antibody producing, have membrane bound antibodies, proliferation......., memory – plasma, point out the molecular interactions.
• Has a T-cell receptor – only recognition of antigens together with MHC molecules. Explain how this work and the difference between class I and class II molecules. Point out the importance of molecular interaction. Explain how Th cells can help B cells - drawing
