Ntawm no yog cov tshuaj ntxuav cov hlab ntsha tsis muaj tshuaj

Cov kws tshawb fawb los ntawm National University of Singapore tau tshawb pom txoj hauv kev cov qe ntshav liab molecules cuam tshuam nrog cov qe ntshav dawb molecules hu ua macrophages kom txo tau qhov mob thiab tsim cov roj deposits ntawm cov hlab ntsha.

Lawv hais tias lawv qhov kev tshawb pom muaj peev xwm kho tau rau tus mob no, uas tuaj yeem ua rau lub plawv nres thiab mob stroke.

Cov qe ntshav liab

Txoj hauv kev tseem ceeb kom xa cov pa oxygen los ntawm lub ntsws mus rau cov ntaub so ntswg ntawm lub cev yog cov qe ntshav liab.

Cov qe ntshav liab ib txwm tsim cov molecules hu ua RBCEV extracellular vesicles thaum lub sij hawm cell aging, kab mob, thiab teb rau ib puag ncig stressors.

RBCEV vesicles tiv thaiv RBCs los ntawm kev tshem tawm cov molecules txaus ntshai, cuam tshuam rau lub cev tiv thaiv kab mob, thiab koom nrog cov txheej txheem inflammatory.

Arteriosclerosis

Atherosclerosis, tsim cov rog, cov roj cholesterol, thiab lwm yam khoom hauv cov phab ntsa ntawm koj cov hlab ntsha, yog ib qho mob uas tuaj yeem ua rau lub plawv nres, mob stroke, aneurysm, lossis ntshav txhaws.

Macrophages, cov qe ntshav dawb uas yog "thawj teb" ntawm lub cev tiv thaiv kab mob, ua lub luag haujlwm tseem ceeb hauv atherosclerosis los ntawm kev noj, sib sau thiab hloov cov lipids mus rau hauv cov hlwb ua npuas ncauj uas pab txhawb thiab tswj kev loj hlob ntawm atherosclerotic plaques.

Kev noj cov macrophages tuag

Txoj kev tshawb no tshiab tau tshuaj xyuas kev sib cuam tshuam ntawm RBCEV vesicles thiab cov qe ntshav dawb hauv kev cia siab ntawm kev tshawb pom txoj hauv kev los tiv thaiv atherosclerosis.

Vim hais tias RBCEV vesicles muaj ntau ntawm PS ntawm lawv daim nyias nyias, cov kws tshawb fawb tau thaiv PS receptors ntawm macrophages, uas txo qis heev.

Tiv thaiv cov hlwb los ntawm oxidation

Tom qab tau txais RBCEV vesicles, macrophages txo qis ntawm cov proteins uas ua rau cov kab mob inflammatory thiab tsim cov enzyme ntau dua uas tiv thaiv cov hlwb los ntawm kev puas tsuaj oxidative feem ntau pom hauv cov kab mob plawv. Qhov tseem ceeb tshaj, RBCEVs ua rau cov macrophages tiv taus los ua npuas hlwb.

Raws li phau ntawv xov xwm Extracellular Vesicles, cov kws tshawb fawb tau hais ntxiv tias kev tshawb fawb ntxiv txog qhov cuam tshuam ntawm RBCEV vesicles siv tsiaj cov qauv ntawm atherosclerosis yuav ua rau kev txhim kho ntawm qhov kev kho mob no.
