Document Summary
3rd way (lecture 2) = bacterium were bound by antibodies from a previous response. The strongest negative feedback of innate immunity is the clearance antigen. For each threat the same cells with the same mop and pale come out for innate immunity. For adaptive immunity, its different it"s got to fit like a glove no same mop and pale. Adaptive immune system mn nestic response (develops memory) unlike innate immune system. Adaptive immune system knows when its seen the same bacterium before and responds more quickly and more intense (faster and stronger). Adaptive immunity starts in the secondary lymphoid organs (lymph nodes, spleen, bone marrow, malt). Dendritic cells = most important, spreads out arms so it can grab antigen. Brings antigen to the closest lymph node it can find. Stop here, see if this is your antigen presenting to t-cell that has the right receptor for it. Natural killer cell wannabe t-cell. (large granular lymphocyte.
