면역이란? -면역, Immunity 라틴어 immunitas ‘질병으로부터의 보호’ -자기와 비자기의 구분(self/non-self discrimination) -면역계, immune system 면역반응, immune response -Immune system: the body's primary defense system against invasion by foreign (microbes)

-Immune response

1) immunological recognition : detection of infection by white blood cells 항원인식

2) immune effector functions ; Complements(보체), Antibody(항체), T cells

3) immune regulation : self regulation by regulatory components

4) immunological memory : long lasting immunity by B, T cells 기억반응 (적응면역)

Chapter 1; 면역계의 개요

선천면역(Innate immune system) vs 적응면역(adaptive immune system)

- Adaptive immune system 효과적이고 강력하게 반응 antigen-specific response slow (take 7 to 10 days) memory antibodies (B-cell), T-cells vaccination, autoimmunity

- Innate immune system 감염에 대한 일차적인 방어선 nonspecific fast response no memory 대식세포(macrophages) 호중구( neutrophils) 자연살해 세포(NK cells) 보체(complement) 인터페론(interferons)

Presentation Notes
innate: attack the invading, foreign microbes within minutes Neu: recruited into the area of infection Phagocytosis, the ingestion of particulate matter into cells for degradation (pattern-recognition molecules) that detect structures commonly found on the surface of bacteria . , interferons, : inhibit the replication of viruses, mediate an early response to viral infection by the innate system . If it fails to clear infection rapidly, it activates the adaptive or acquired immune response, which takes over. Messenger molecules known as cytokines mediate the connection between the two systems

적응면역(adaptive immune system)

Clonal selection (클론선택설) : each B cell or T cell expressing a receptor that best fits the antigen

divides, produces daughter cells (clones) that have the same receptor

적응면역(adaptive immune system) Autoimmunity(자가면역) : the immune system that recognize self autoimmune disease e.g.,Diabetes mellitus(당뇨병) Vaccination (백신) : based on memory of a previous encounter with antigen e.g., HBV, influenza vaccine
