In type III hypersensitivity type III hypersensitivity Type III hypersensitivity tshwm sim thaum muaj kev sib txuam ntawm cov tshuaj tiv thaiv kab mob(antigen-antibody complexes) uas tsis tau raug tshem tawm los ntawm lub cev tsis muaj zog, Ua rau muaj kev cuam tshuam inflammatory thiab attraction ntawm leukocytes. Cov tshuaj tiv thaiv zoo li no tuaj yeem ua rau cov kab mob tiv thaiv kab mob. https://en.wikipedia.org › wiki › Type_III_hypersensitivity

Qee qhov kev mob tshwm sim tuaj yeem muab cov yam ntxwv ntawm hom II thiab III hypersensitivity nrog kev tsim cov tshuaj tiv thaiv kab mob hauv qhov chaw.
hom tshuaj tiv thaiv autoimmune?
Txawm li cas los xij, lub cev tiv thaiv kab mob qee zaum ua haujlwm tsis zoo, txhais lub cev cov ntaub so ntswg txawv teb chaws thiab tsim cov tshuaj tiv thaiv kab mob (hu ua autoantibodies) lossis lub cev tiv thaiv kab mob uas tsom thiab tua cov hlwb lossis cov ntaub so ntswg ntawm lub cev. Cov lus teb no yog hu ua cov tshuaj tiv thaiv autoimmune. Nws ua rau mob thiab cov ntaub so ntswg puas
Puas yog Hom II hypersensitivity autoimmune?
Cov no tau dim ntawm tus kheej-reactive hlwb tuaj yeem tua cov nqaij noj qab haus huv thiab ua rau muaj kab mob autoimmune. Nyob rau hauv hom II hypersensitivity no cov dim ntawm tus kheej-reactive B hlwb ua activated thiab tsim IgM los yog, nrog kev pab los ntawm CD4 zoo T pab hlwb, IgG cov tshuaj tiv thaiv uas txuas mus rau antigens ntawm host cells.
4 hom kev ntxhov siab yog dab tsi?
Plaub hom kev ntxhov siab yog:
- Type I: cov tshuaj tiv thaiv kho mob los ntawm IgE antibodies.
- Hom II: cytotoxic cov tshuaj tiv thaiv kho mob los ntawm IgG lossis IgM cov tshuaj tiv thaiv.
- Type III: cov tshuaj tiv thaiv los ntawm kev tiv thaiv kab mob.
- Type IV: ncua sij hawm cov tshuaj tiv thaiv los ntawm cov lus teb ntawm tes.
