2. Adaptive and Innate Immunity Macrophages and neutroph i ls provide first line of defense However, can not always eliminate infectious microorganisms Lymphocytes of the adaptive immune system provide a more versatile means of defense Innate cells however play a crucial role in initiation and subsequent direction of the adaptive immune response

3. Adaptive and Innate Immunity Most infectious agents induce inflammatory responses by activating innate immunity Activation of specialized antigen presenting cells is necessary first step for induction of adaptive immunity Lymphocytes activated by antigen give rise to clones of antigen specific cells that mediate the adaptive immunity
