Enzymes yog qhov tshwj xeeb hauv ob qho tib si hauv cov tshuaj tiv thaiv uas lawv catalyze thiab hauv lawv xaiv cov reactants, uas yog hu ua substrates. Ib qho enzyme feem ntau catalyzes ib qho tshuaj tiv thaiv ib leeglossis ib txheej ntawm cov tshuaj tiv thaiv zoo sib xws.
Yuav siv tau cov enzyme rau ib qho tshuaj tiv thaiv?
Ntau zaus tshaj tsis yog, nws muaj kev nyab xeeb xav tias ib leeg enzyme nyiam ua rau tsuas yog ib qho tshuaj tiv thaiv, lossis ib txheej ntawm cov kev cuam tshuam zoo sib xws. (Peb, raws li cov neeg soj ntsuam sab nraud, tuaj yeem hais qhia tom qab-qhov tseeb tias ntau cov enzymes --tab sis tsis yog txhua tus ntawm lawv -- feem ntau muaj npe rau lawv ua li cas.)
Muaj pes tsawg cov tshuaj tiv thaiv enzyme catalyze?
Cov enzymes no tuaj yeem ua tau ntau npaum li 106-107 cov tshuaj tiv thaiv ib ob. Ntawm qhov tsis sib xws, txwv tsis pub enzymes limp nrog thaum ua haujlwm tsuas yog ≈10-1-10-2 cov tshuaj tiv thaiv ib ob lossis txog ib qho tshuaj tiv thaiv ib feeb ib enzyme (BNID 101627, 101635).
Vim li cas cov enzyme yuav tsis ua rau lwm yam tshuaj tiv thaiv?
Qhov no yog vim lawv tsis hloov lub zog dawb ntawm cov reactants lossis cov khoom. Lawv tsuas yog txo qhov ua kom lub zog xav tau rau cov tshuaj tiv thaiv mus rau pem hauv ntej (Daim duab 1). Tsis tas li ntawd, ib qho enzyme nws tus kheej tsis hloov pauv los ntawm cov tshuaj tiv thaiv nws catalyzes.
Vim li cas cov enzymes tsuas yog ua rau ib qho tshuaj tiv thaiv?
Enzymes yog cov proteins, uas muaj cov qauv 3D tertiary tshwj xeeb, nrog rau qhov tshwj xeeb zoo li lub xaib. Lub chaw nquag tuaj yeem khi ib lub substrate los tsim cov enzyme-substrate complex, yog li ntawd tuaj yeem ua rau tsuas yog ib qho tshuaj tiv thaiv xwb.

Dab tsi yog qhov txawv ntawm cov tshuaj tiv thaiv thiab tshuaj tiv thaiv?
Raws li nouns qhov txawv ntawm antitype thiab hom yog hais tias antitype yog ib yam dab tsi uas yog cim los yog sawv cev los ntawm ib homthaum hom yog ib pab pawg raws li cov yam ntxwv sib koom; ib hoob . Antitype txhais li cas? 1a:
Puas yog cov tshuaj tiv thaiv kab mob sib txuas tau suav tias yog kev tiv thaiv kab mob?
Antibody drug conjugates (ADCs) yog ib hom tshuaj tiv thaiv kab mob. Lawv yog tsim los ntawm peb yam: monoclonal antibody (mAb) thiab cytotoxic payload ua los ntawm cov kws khomob kws khomob, uas txuas nrog ua ke siv cov tshuaj sib txuas .

Puas yog cov tshuaj tiv thaiv kab mob tiv thaiv kab mob ua rau lupus?
Antinuclear cov tshuaj tiv thaiv yog autoantibodies - cov tshuaj tiv thaiv kab mob uas tsom rau cov proteins ib txwm nyob hauv lub hauv paus ntawm lub cell. Qhov no dhau los ua qhov tseem ceeb hauv kev kho mob thaum ANAs teeb liab lub cevpib tsom nws tus kheej, uas tuaj yeem ua rau cov kab mob autoimmune, suav nrog lupus, Sjogren's syndrome, thiab cov kab mob sib xyaw ua ke .
Cov tshuaj tiv thaiv kab mob puas muaj kev tiv thaiv kab mob?
Nws yuav siv sijhawm ntev npaum li cas txhawm rau txhim kho kev tiv thaiv kab mob COVID-19 tom qab tau txais cov tshuaj tiv thaiv? tshuaj tiv thaiv COVID-19 qhia peb lub cev tiv thaiv kab mob kom paub txog thiab tawm tsam tus kab mob uas ua rau COVID-19.
