Neurofibrillary tangles (NFTs) yog kev sib koom ua ke ntawm cov protein hyperphosphorylated tau uas feem ntau paub tias yog thawj qhov cim ntawm Alzheimer's disease. Lawv lub xub ntiag kuj tseem pom nyob hauv ntau lwm yam kab mob hu ua tauopathies.
Thiaj li, dab tsi yog neurofibrillary tangles ua los ntawm?
Neurofibrillary tangles yog cov roj ntsha uas tsis tuaj yeem pom hauv lub hlwb lub hlwb. Cov no tangles suav nrog feem ntau ntawm cov protein hu ua tau, uas yog ib feem ntawm tus qauv hu ua microtubule. Lub microtubule pab thauj cov as -ham thiab lwm yam tshuaj tseem ceeb los ntawm ib feem ntawm cov leeg hlwb mus rau lwm qhov.
Ib tus kuj tseem yuav nug tau tias, txhais tau li cas los ntawm lo lus neurofibrillary tangles? Txhais ntawm neurofibrillary tangle .: cov kab mob pathological txuam nrog ua ke cov xov paj helical tsim los ntawm kev tsim txawv txav tau cov protein uas pom muaj feem ntau hauv cytoplasm ntawm cov neurons ntawm lub hlwb thiab tshwj xeeb tshaj yog lub paj hlwb cortex thiab hippocampus thiab uas tshwm sim feem ntau hauv Alzheimer's tus kab mob.
Ntawm no, ua li cas cov neurofibrillary tangles cuam tshuam rau lub hlwb?
Neurofibrillary tangles yog txawv txav ntawm cov protein hu ua tau uas sau hauv cov neurons. Beta-amyloid clumps rau hauv cov plaques nruab nrab ntawm cov neurons. Raws li qib beta-amyloid nce mus txog qhov taw tes, muaj kev sib kis sai tau ntawm thoob plaws lub hlwb.
Dab tsi yog neurofibrillary tangles quizlet?
Neurofibrillary tangles . -intracellular, tsis xwm yeem phosphorylated tau protein = cov ntsiab lus cytoskeletal tsis haum. - tangles sib txheeb nrog qib kev dementia.

Dab tsi yog glycoprotein dab tsi yog ib qho ntawm kev siv glycoproteins?
Glycoproteins yog cov protein uas muaj cov oligosaccharide saw (glycans) covalently txuas nrog cov amino acid sab-saw. Glycoproteins kuj tseem yog ib qho tseem ceeb ua ke ntawm cov protein, uas lawv ua lub luag haujlwm hauv kev sib cuam tshuam ntawm tes -cell
Dab tsi yog cov khoom siv hauv lub cev zom zaub mov thiab lawv lub luag haujlwm yog dab tsi?
Cov khoom siv hauv lub cev zom zaub mov suav nrog cov hniav, tus nplaig, cov qog ua kua qaub, daim siab, lub zais zis, thiab txiav txiav. Txhawm rau ua tiav lub hom phiaj ntawm kev muab lub zog thiab khoom noj khoom haus rau lub cev, rau lub luag haujlwm tseem ceeb nyob hauv cov txheej txheem zom zaub mov: nqos. Kev zais
Dab tsi yog qhov kev nkag siab tsis tu ncua thiab dab tsi yog qhov loj me me qhov ntev xim tsis tu ncua zoo li qub)?
Kev nkag siab tsis tu ncua, tseem hu ua qhov tsis sib xws, lossis qhov tshwm sim tsis tu ncua, kev nyiam tsiaj thiab tib neeg kom pom cov khoom paub zoo li muaj tus qauv zoo, qhov loj me, xim, lossis qhov chaw tsis hais txog kev hloov pauv ntawm lub kaum sab xis ntawm kev xav, nrug deb, lossis teeb pom kev zoo
Lub cev tseem ceeb ntawm lub plab zom mov yog dab tsi thiab lawv lub luag haujlwm yog dab tsi?

Txhawm rau ua tiav lub hom phiaj ntawm kev muab lub zog thiab khoom noj khoom haus rau lub cev, rau lub luag haujlwm tseem ceeb nyob hauv cov txheej txheem zom zaub mov: nqos. Kev zais. Sib tov thiab txav mus los. Digestion. Kev nqus. Kev tshem tawm
Neurofibrillary tangles ua rau dementia li cas?
Neurofibrillary tangles yog qhov txawv txav ntawm cov protein hu ua tau uas sau rau hauv cov neurons. Hauv Alzheimer's tus kab mob, txawm li cas los xij, kev hloov pauv tshuaj txawv txav ua rau tau tshem tawm ntawm microtubules thiab lo rau lwm cov tau molecules, tsim cov xov uas nws thiaj li koom ua tangles hauv neurons
