Introduction of Immunology Concept of Immunity Immune Response Immune Cells Tissues and Organs of the Immune System Immunopathology
Immunity 1. Immunity: meaning the state of protection from infectious disease In 430BC, a plaque in athens Those who recovered from the plaque would not contact the disease a second time 2. Agents: microorganisms(viruses, bacteria etc and their products foods, chemicals, pollen, tumor cells, etc 3. Immune system: immune tissues and organs, immune cells immune molecules 4.Immune response: collective and coordinated response to the introduction of foreign substances 5. Immunology: study the structure of immune system and its functions

Immune Response Innate immune response natural immune response non-specific immune response o Adaptive immune response acquirea immune response specific immune response
Immune Response Innate immune response natural immune response non-specific immune response Adaptive immune response acquired immune response specific immune response
The innate and adaptive immune response Characteristics Cells Molecules Innate immunity r Responds rapidly / Physical barriers Humoral factors No memory pHagocytes(PMNs Complement rNo or low and macrophages) Acute phase specificity r Natural killer cells Proteins cYtokines Adaptive immunit rEsponds Slowly T cells ANtibodies MEmory rB cells Cytokines r Highly specific Dendritic cells r Granzymes

Innate immunity mechanism of recognition o Pathogen associated molecules patterns(PAMPs): LPS, DNA, RNA, Protein o Danger-associated molecular patterns DAMPS〕: DNA,HSP o Pattern recognition receptors(PrR): Toll-like receptor (TLR), C-lectin recptor(CLR), RIG-1-Like recptor(rlr), NoD-like Receptor(Nlr)
