Cov kws tshawb fawb tam sim no tau hloov CRISPR RNA-txiav enzyme rau hauv cov tshuaj tiv thaiv kab mob uas tuaj yeem tsim kho kom pom thiab rhuav tshem RNA-raws kab mob hauv tib neeg lub hlwb. Ntau lub ntiaj teb cov kab mob feem ntau tshwm sim los yog tuag taus tib neeg yog RNA-based kab mob -- Ebola, Zika thiab mob khaub thuas, piv txwv li -- thiab feem ntau tsis muaj kev kho mob uas FDA pom zoo.
Ua ke, puas muaj enzymes hauv cov kab mob?
Ib txhia kab mob tsis muaj cov enzymes tag nrho sab hauv kab mob vais lav particle nws tus kheej. Qee qhov tshwj xeeb cov enzymes uas feem ntau ua nyob rau hauv tus tswv tsev cell yog RNA polymerase uas duplicates tus kab mob RNA thiab transposase uas txav cov kab mob DNA mus rau lwm qhov chaw hauv tus tswv tsev DNA.
Tom qab ntawd, lo lus nug yog, dab tsi yog qee yam enzymes uas tus kab mob no tau nruab? Ib tsev neeg loj ntawm ib leeg-stranded RNA kab mob hu ua Retroviridae; RNA ntawm cov kab mob no yog qhov zoo, tab sis cov kab mob no tau nruab nrog ib qho enzyme, hu ua a rov qab transcriptase , uas theej ib leeg-stranded RNA los ua ob-stranded DNA.
Ib yam li ntawd, koj yuav nug, cov enzymes puas tuaj yeem tua cov kab mob?
Tsis zoo li cov tshuaj tua kab mob, uas feem ntau yog broad spectrum thiab tua ntau yam sib txawv kab mob pom nyob rau hauv tib neeg lub cev, tej yam uas muaj txiaj ntsig, phage cov enzymes xwb tua tus kab mob kab mob nrog me ntsis kom tsis muaj kev cuam tshuam rau tib neeg ib txwm kab mob flora.
Puas muaj enzymes ciaj sia?
Enzymes tsis yog ciaj . Lawv yog cov tshuaj complex uas tsim los ntawm cov kab mob. Lawv tsis tuaj yeem rov tsim dua, lossis siv tau pov tseg. Lawv ua kom nrawm tshuaj lom neeg yam tsis tau siv lawv tus kheej.
