Specific Defense Mechanism

Specific Defense Mechanism System immunity Specific more effective compared to with system immunity nonspecific And have something component memory Which speed up time response when invader type Which The same found Again. Immunity generated from production antibody Specific Which specialized For antigens attacker. Antigen abbreviation from antibody-generators , is something molecule marker Which there is on surface all type cell. Antibody tie antigens Andturn off or disable microbes through a number of method. Most antibody is proteins or something mixture between proteins And polysaccharides. Antigens can is molecule What just Which cause production antibody. Humorous Immunity Immunity humorous arranged by cell B And antibody Which it produces. Immunity Which mediated cell controlled by cell Q. Reaction antibody Which mediated protect to attack virus And bacteria. Immunity cell Which mediated relate with cell in body Which has caught infection virus And bacteria, protect from parasite, fungi, And protozoa, And Also kill cell cancer. Steps on immunity humorous is: 1) detection antigens, 2) activation cell Q helper, And 3) production antibody by cell B. a. Detection Antigen Every object foreign Which enter body will emit antigens. Antigen is molecule typical Which owned by every object Which enter body. Antigen will recognized by antibody, that is something substance Which issued by cell lymphocytes For tie And agglomerate antigens. b. Activation Sel T Helper Cell Q helper is macrophage Which activated when face antigens Which exposed on surface membrane the cell. When contact between macrophage And antigens attacker happen macrophage the, Then will tie antigens the And present it to cell Q helper. Presentation the stimulate cell Q helper For do three matter. First that is produce clone cell Q memory, second stimulate cell B For produce cells plasma And cells B memory And Which third stimulate cell Q cytotoxic For produce cells Q cytotoxic And cells Q memory. c. Production Antibody by Cell B When cell B stimulated by cell Q helper, cell B Then form cell plasma And cell B memory. Cell plasma make And release 2000 until 20,000 antibody per second to in blood For four or five day. Cell B memory life during a number of month or year, And become part from system immunity. 1) Antibody And Antigen Molecule antibody shaped Y Which consists on two polypeptide long And two polypeptide short. Function antibody is For introduction And binding antigens. Antibody is proteins Which produced by lymphocytes as answer on antigens Specific. Antibody tie antigens Specific with lockand-key method that forms a complex antigen-antibody. Antibody is something type molecule proteins Which known as immunoglobulins. There is five class immunoglobulins: IgG, IgA, IgD, IgE, And IgM. End Y is place merger antigens with antibody. End This different the shape And typical For each antigens. Antigen is substance chemistry Which there is on surface something cell. All cell own antigens. System immunity inspect every cell And identify it as “ self Alone" or “ No self myself . " Cell Which have antigens foreign will recognized by antibody as No self Alone so that will attack cell the, whereas cell body emit antigens Which Already recognized by antibody as self Alone so that No attacked. Lymphocytes B And lymphocytes Q produce antibody. Lymphocytes B become cell plasma Which Then produce antibody. Lymphocytes Q attack cell carrier antigens has recognized in a way special. They Also become intermediary response immunity.
