A prion (luv rau proteinaceous kis kab mob kis) yog ib hom tshwj xeeb ntawm tus neeg sawv cev kis mob, zoo li nws yog tsuas yog ua los ntawm cov protein.

Ntxiv mus, dab tsi yog prion hauv biology?

Prion , daim ntawv tsis txawv txav ntawm cov protein uas tsis zoo ib txwm pom hauv lub hlwb uas yog lub luag haujlwm rau ntau yam kab mob kev tuag ntawm cov tsiaj, suav nrog tib neeg, hu ua transmissible spongiform encephalopathies. Prion . cov neeg tseem ceeb. Susan L. Lindquist.

Qhov thib ob, cov tsos mob ntawm tus kab mob prion yog dab tsi? Cov tsos mob ntawm cov kab mob prion suav nrog: Kev loj hlob sai sai ntawm dementia. Nyuaj taug kev thiab hloov pauv. Hallucinations. Cov leeg nruj.

Yog li ntawd, dab tsi ua rau prions tsim?

Prion kab mob yog ua los ntawm misfolded daim ntawv ntawm prion protein, tseem hu ua PrP. Hauv txhua tus kab mob, tus prion protein (PrP) quav rau txoj kev tsis raug, dhau los ua prion , thiab ces ua lwm cov PrP molecules ua tib yam. Prions Tom qab ntawd tuaj yeem kis tau "nyob ntsiag to" hla ib tus neeg lub hlwb rau xyoo tsis muaj ua tej tsos mob.

Vim li cas prions thiaj li txaus ntshai?

Prions yog cov kab mob sib kis uas tsis tau pom dua uas ua rau pab pawg ntawm cov kab mob tuag taus neurodegenerative los ntawm cov txheej txheem tshiab. Lawv yog cov kis tau yooj yim uas tsis muaj cov nucleic acid. Vim lawv cov yam ntxwv zoo ib yam, Prions tawm raws li qhov muaj peev xwm txaus ntshai txij li lawv tuaj yeem siv los tsim cov riam phom zoo li no.
