Yog li, yog tias koj muaj E coli hauv koj lub cev, koj lub cev tiv thaiv kab mob yuav cuam tshuam nrog nws cov proteins ntawm qhov chaw, ntawm qee qhov yog glycosylated, ces cov antigens yog glycoproteins. Antigens lawv tus kheej tsuas yog ua rau lub cev tiv thaiv kab mob. Yog li qhov no tuaj yeem ua tau txhua yam.
Vim li cas glycoproteins ua li antigens?
Glycoproteins tseem ceeb rau kev tsim tawm vim tias lawv tso cai rau khi ntawm cov phev cell mus rau saum npoo ntawm qe. … Cov carbohydrate ntawm cov tshuaj tiv thaiv kab mob (uas yog glycoproteins) txiav txim siab cov antigen tshwj xeeb uas nws tuaj yeem khi. B hlwb thiab T hlwb muaj glycoproteins saum npoo uas khi antigens, zoo li.
Kev ua haujlwm ntawm glycoproteins yog dab tsi?
Glycoproteins yog cov molecules uas muaj cov protein thiab carbohydrate chains uas koom nrog ntau lub zog ntawm lub cev suav nrog kev tiv thaiv. Ntau tus kab mob muaj glycoproteins uas pab lawv nkag mus rau hauv lub cev hlwb, tab sis kuj tseem tuaj yeem ua haujlwm tseem ceeb hauv kev kho mob lossis kev tiv thaiv lub hom phiaj.
Lub luag haujlwm ntawm glycoproteins hauv cell membrane yog dab tsi?
Glycoproteins yog cov protein tshwj xeeb uas muaj oligosaccharides txuas rau lawv. … Hauv particular, glycoproteins nyob rau hauv lub cell membrane yog tseem ceeb heev rau cell-to-cell paub thiab adhesion, nrog rau kev pab raws li receptors rau lwm hom molecules.
piv txwv ntawm glycoproteins yog dab tsi?
Qee qhov piv txwv uas pom glycoproteinsib txwm:
- Ycollagen.
- mucins.
- transferrin.
- ceruloplasmin.
- immunoglobulins.
- antibodies.
- histocompatibility antigens.
- hormones (xws li follicle-stimulating hormone, luteinizing hormone, human chorionic gonadotropin, thyroid-stimulating hormone, erythropoietin, alpha-fetoprotein)

Puas yog cov tshuaj tiv thaiv kab mob antigens?
Thaum ib qho antigen khi rau lub cev receptor molecule, nws yuav lossis tsis ua rau lub cev tiv thaiv kab mob. Antigens uas ntxias cov lus teb no yog hu ua immunogens. Yog li, nws tuaj yeem hais tias tag nrho cov immunogens yog antigens, tab sis tsis yog txhua tus antigens yog immunogens.
Dab tsi yog qhov txawv ntawm tus kheej thiab tsis yog tus kheej antigens?
Cov antigens ntawm koj tus kheej lub hlwb hu ua tus kheej-antigens, thaum cov uas tsis muaj hauv koj lub cev yog hu ua non-self antigens. … Cov tshuaj tiv thaiv tsis yog tus kheej muaj nyob rau ntawm cov kab mob thiab cov kab mob xws li mob khaub thuas thiab kab mob tetanus, uas nkag mus rau koj lub cev thiab ua rau koj mob.
Glycoproteins thiab glycolipids ua tiav rau qhov twg?
Golgi apparatus, lossis Golgi complex, ua haujlwm raws li lub Hoobkas uas cov protein tau txais los ntawm ER tau ua tiav ntxiv thiab txheeb xyuas kev thauj mus los rau lawv qhov chaw kawg: lysosomes, cov ntshav. membrane, los yog secretion. Tsis tas li ntawd, raws li tau sau tseg ua ntej, glycolipids thiab sphingomyelin yog synthesized hauv Golgi.
Antigens tuaj qhov twg?
Ntseeg antigens keeb kwm los ntawm sab nraud lub cev. Piv txwv suav nrog cov khoom lossis cov khoom tsim los ntawm cov kab mob lossis cov kab mob (xws li cov kab mob thiab cov protozoa), nrog rau cov tshuaj nyob rau hauv nab venom, qee cov proteins hauv cov zaub mov, thiab cov khoom ntawm cov ntshav thiab cov qe ntshav liab los ntawm lwm tus neeg.
Puas neutrophils muaj antigens?
Neutrophils tuaj yeem nthuav tawm antigens rau antigen-specific nco CD4 + T cells tab sis MDCs thiab monocytes muaj peev xwm tshaj plaws. Dab tsi yog cov antigen nthuav tawm cov hlwb? Antigen-presenting cells (APCs) yog ib pawg neeg tsis muaj zog tiv thaiv kab mob uas kho cov kab mob hauv lub cev los ntawm kev ua thiab nthuav tawm cov tshuaj tiv thaiv rau kev lees paublos ntawm qee cov lymphocytes xws li T hlwb.
