Immune System And Memory To Infection

Immune System And Memory to Infection Immunity secondary is immunity to disease certain after very caught disease the. Immunity This possible by production cell memory B And cell memory Q when contact Which First to antigens. Something contact Which short to antigens Which The same For second time produce response Which more fast And big. Response secondary is base For vaccination. 1. Vaccination Vaccine made from pathogen Which has killed or Which Already weakened. Vaccine stimulate production antibody And formation cell memory without cause disease. Immunity active developed after something disease or vaccine develop antibody. Immunity passive is type immunity when individual given antibody For attack something disease Specific. Immunity passive aged short. 2. Group Blood Antigen And antibody form group blood. On transfusion, group blood recipient And donor must customized. If two group blood Which No The same combined, system immunity recipient will produce antibody Which cause clumping blood Which transfused, obstruct circulation through capillary or even caused fatal. a. Group Blood ABO Group blood ABO determined by gene I (isoagglutinin). There is three allele gene I namely, IABO, I and I. The proteins produced by the A and B alleles are mutually antigenic. Classification blood And mechanism transfusion blood can seen on table following. People with AB blood type can accept blood from all groups blood. They Which have group O blood can donate to everyone group blood. If something transfusion between receptors and donors are in conflict, blood recipient will experience clumping blood. Antigen reactions to cells and antibody in in plasma will result clumping on capillary, damage cell, And release hemoglobin Which can crystallize in in kidney And result failure kidney. b. Group Blood Rh Group blood Rh consists from Rh positive ( Rh+) Which make antigens Rh Where group blood Rh negative (Rh–) Which No Can. Disease hemolytic on child new born (HDN) caused by incompatibility between Rh- from Mother with Rh+ from fetus. Blood Rh+ from fetus enter to system immunity si Mother during process birth, caused it produce antibody Rh. Child First on generally No affected, However fetus with Rh+ next will cause reaction system immunity secondary Which great. For prevent HDN, Mother with Rh- given antibody Rh during pregnancy First with thereby No will attack fetus. 3. Allergy And Chaos System Immune System immunity can Act exceed limit Which cause allergy or autoimmune. Reason allergy is element Which cause allergy, covers dust, spores, powder sari, food certain, And a number of type drug. After contact with reason allergy, system immune make antibody from cell B and memory T cells. Subsequent contact with the same allergen cause response immunity secondary Which big with release Lots antibody. Cells Then release histamine, Which start response inflammation. System immunity remember per- different between cell body And attacker foreign. Disease autoimmune happen when system immunity attack And destroying cells and self. Arthritis, complex sclerosis, lupus erythematosus, and rheumatoid artistic is part of the disease autoimmune. mmunodeficiency caused by failure or deficiency of one or more part system immunity. Individual Which suffer immunodeficiency sensitive to disease Which in a way normal No will annoys most people. Abnormalities genetic, Disease Hodgkin's, chemotherapy cancer, And therapy radiation can cause disease immunodeficiency. Immunodeficiency syndrome from the HIV virus (AIDS) is a case of decline immunity consequence destruction Q cell by virus HIV. HIV in a way selective infect And kill cell Q helper. RNA cell Q changed become DNA virus HIV by enzyme the opposite transcriptase. DNA This Then put together to in chromosome man during months or annual take. Information: 1 . When enter body, HIV attack cell Q (lymphocytes) 2. HIV enter cell Q 3. HIV break cell Q 4. Enzyme virus replicate RNA become DNA And join with DNA cell Q 5. HIV silent in in cell Q during a number of moment 6 . When cell Q activated, RNA virus changed become virus active Then kill And go out from cell Q When cell Q Which caught infection required For respond immunity, gene virus activated And virus replicate, kill cell Which infected And repeat something cycle new on cell Q next. By gradually amount cell Q Which is leader system immunity decline. Response system immune become reduce, even sometimes No succeed.
