Document Summary
Overview adaptive immunity: introduction of apc, mhc, t cells and b cells. Innate immunity: barriers to infection and principal immune cells: phagocytosis and natural killing, principles of innate recognition and activation, local innate inflammatory processes and initiation of adaptive immune responses. Adaptive immunity: overview adaptive immunity: introduction of apc, mhc, t cells, and b cells, antigen processing and presentation, generation of diversity (t and b cells, the thymus and t cell development. If adaptive immunity cannot recognize the pathogen, there is no way it can mount a response: we cannot allow immune response to go forever and we cannot allow immune response to be too much can cause self-disruption. Immune recognition: macrophage can recognize pathogen itself and pathogen products, both pathogens and pathogen components can be recognized by innate immune system components such as macrophages. Class 2: dendritic cell is the most professional because they can provide both mhc class 1 and.
