Adaptive Immunity

QuestionAnswer
Adaptive Immunity Involves the ability to recognize, respond to, and remember a particular substance
Stimulants and Types of Adaptive Immunity -Stimulants> *Antigens: Large molecules **Foreign: Not produced by body, introduced from outside **Self-antigens: Produced by body **Haptens: Small molecules and capable of combining =Types *Humoral or Antibody-mediated: B cells *Cell-mediated:tcel
Origin and Development of Lymphocytes B and T cells --Originate in red bone marrow --Move to lymphatic tissue from processing sites and continually circulate ---Clones are small groups of identical lymphocytes
Origin and Development of Lymphocytes II Positive selection= Ensures survival of lymphocytes that react against antigens -Negative selection= Eliminates lymphocytes that react against self-antigens
Origin and Development of Lymphocytes III Primary lymphatic organs (red bone marrow, thymus)= Where lymphocytes mature into functional cells --Secondary lymphatic organs =Where lymphocytes produce an immune response
Major Histocompatability Complex (MHC) -Most lymphocyte activation involves glycoproteins of cell surfaces called MHC molecules --Class I molecules display antigens on surface of nucleated cells, resulting in destruction of cells --Class II molecules display antigens on surface of antigen-presenting cells, resulting in activation of immune cells
