Select All Inflammation Characterized by vascular changes and activation of leukocytes. Clearance of the cauasative agent (e.g. infection) and wound repair restores homeostasis. Participating Cells: mast cells, phagocytes, and platelets. Pathogen Associated Pattern Molecules Common structural features of pathogens (e.g. cell wall and capsule of bacteria) that have developed over evolution and are recognized by INNATE immunity receptors. This is non-clonal, non-specific, non-adaptive, but is very effective at recognizing pathogen. Humoral Immunity Adaptive immunity that can be transferred between individual with transfer of serum. Mediated by antibodies (produced by B-lymphocytes). Cellular Immunity Adaptive Immunity that can be transferred only with transfer of live lymphocytes. Mediated by T-lymphocytes and their products. 4 Functional Units of the Adaptive Immune System 1) Recognition --Specific, and has memory 2)Amplification --due to cell division and activation of enzyme cascades. 3)Regulation 4)Effector Mechanisms Antigens Structures specifically recognized by T & B lymphocytes, as well as antibody. Recognized by antigen receptors.
