Pab pawg Neeg Tshawb Xyuas Asmeskas Tshawb Xyuas 'nyob' Neeg Hlau Nrog Hlwb

Cov kws tshawb nrhiav Asmeskas tau tsim ib cov "muaj sia" neeg hlau raws li ib lub cell. Cov kab mob organic no tuaj yeem txav mus rau lub hom phiaj tau hais tseg, thiab tom qab txiav, nws tuaj yeem kho nws tus kheej. Cov kev tshawb fawb tau muab luam tawm nyob rau hauv phau ntawv Journal ntawm National Academy of Sciences rau hnub tim 13.

Cov kws tshawb fawb ntawm University of Vermont hauv tebchaws United States thawj zaug tau tsim cov kev hloov pauv ntawm cov txheej txheem supercomputer mus rau kev sim ib qhov kev tsim qauv raws cov cai ntawm biophysics. Tom qab, cov kws tshawb fawb ntawm Tufts University hauv Tebchaws Meskas tau muab cov qia hlwb los ntawm Xenopus embryos thiab cog rau hauv cov tawv nqaij lossis cov hlwb myocardial. Tom qab faib lawv rau hauv tus kheej lub hlwb, lawv tau sib sau ua ke hauv qab lub tshuab tsom kab rau cov qauv zoo ib yam li cov qauv tsim.

Cov kev tshawb fawb pom tau hais tias yav dhau los ua daim ntawv cog lus cardiomyocytes tuaj yeem mus tom ntej hauv cov txheej txheem zoo thiab muaj kev ywj pheej thiab txav mus tau ob peb hnub lossis ntau lub hlis hauv ib puag ncig zoo nkauj. Cov kev sim txuas ntxiv qhia pom tias cov "neeg muaj sia nyob" neeg hlau no tuaj yeem txav mus rau hauv lub nplhaib thiab thawb lub npas mus rau hauv qhov chaw ua ke. Cov kws tshawb nrhiav txiav cov neeg hlau no tawm ntawm lawv, thiab lawv tuaj yeem sib dhos ua ke los txuas ntxiv ua haujlwm, uas tsis tuaj yeem ua nrog cov neeg hlau ib txwm ua.

Tus kws sau ntawv ntawm daim ntawv, Tufts University biologist Michael Levin, hais tias "nyob" neeg hlau cia siab yuav siv rau yav tom ntej los tshawb nrhiav rau kev ua paug xov tooj cua, khaws cov kab mob me me hauv hiav txwv, lossis tshem cov plaques atherosclerotic hauv cov hlab ntsha.
