Kas yra mirties p\u0117dsakas?<\/h2>\n

\u017dmogaus organizme kasdien nat\u016braliai \u017e\u016bsta \u0161imtai milijard\u0173 l\u0105steli\u0173, o \u0161is procesas vadinamas apoptoze. Iki \u0161iol manyta, kad l\u0105stel\u0117 suirsta gana chaoti\u0161kai, o liku\u010dius greitai pa\u0161alina imunin\u0117s sistemos l\u0105stel\u0117s.<\/p>\n

Naujas tyrimas parod\u0117, kad apoptoz\u0117 gali palikti gerokai labiau organizuot\u0105 signal\u0105. Pasitelk\u0119 trimat\u0119 laiko t\u0117km\u0117s mikroskopij\u0105, mokslininkai u\u017efiksavo anks\u010diau nepasteb\u0117tus ma\u017ey\u010dius i\u0161or\u0117s p\u016bsleli\u0173 darinius, susidaran\u010dius \u017e\u016bstant l\u0105stelei.<\/p>\n

\u0160ios p\u016bslel\u0117s pavadintos F-ApoEVs ir jos tarsi pa\u017eymi viet\u0105, kur l\u0105stel\u0117 \u017euvo. Tyr\u0117j\u0173 teigimu, toks p\u0117dsakas padeda imuninei sistemai grei\u010diau rasti \u017euvusios l\u0105stel\u0117s liku\u010dius ir juos saugiai \u201esutvarkyti\u201c.<\/p>\n

Kod\u0117l tai svarbu imuninei sistemai?<\/h2>\n

Efektyvus mirusi\u0173 l\u0105steli\u0173 pa\u0161alinimas laikomas viena svarbiausi\u0173 organizmo apsaug\u0173 nuo u\u017esit\u0119susio u\u017edegimo. Jei l\u0105steli\u0173 fragmentai u\u017esilaiko audiniuose, jie gali skatinti netiksling\u0105 imunin\u012f aktyvum\u0105 ir didinti autoimunini\u0173 reakcij\u0173 rizik\u0105.<\/p>\n

Mokslininkai ai\u0161kina, kad F-ApoEVs gali veikti kaip kryptingas signalas, padedantis imunin\u0117ms l\u0105stel\u0117ms ne tik aptikti \u017euvimo viet\u0105, bet ir grei\u010diau \u201eu\u017edaryti\u201c proces\u0105 be perteklinio u\u017edegimo. Tai kei\u010dia supratim\u0105 apie tai, kaip tvarkingai organizmas pri\u017ei\u016bri audini\u0173 \u0161var\u0105.<\/p>\n

Kaip virusai tai paver\u010dia ginklu?<\/h2>\n

Did\u017eiausia staigmena paai\u0161k\u0117jo tyrimuose su gripo virusu. Laboratoriniuose eksperimentuose dalis viruso daleli\u0173, pasak autori\u0173, sugeb\u0117jo pasisl\u0117pti naujai apra\u0161ytose F-ApoEVs p\u016bslel\u0117se.<\/p>\n

Tuomet, kai imunin\u0117 sistema atvyksta \u201esutvarkyti\u201c apoptoz\u0117s p\u0117dsako, virusas gali pasinaudoti \u0161iuo nat\u016braliu transportu ir patekti \u012f gretimas sveikas l\u0105steles. Tai si\u016blo papildom\u0105 plitimo keli\u0105, kuris gali pad\u0117ti virusams i\u0161 dalies i\u0161vengti ankstyvo imunin\u0117s sistemos atpa\u017einimo.<\/p>\n

Iki \u0161iol dauguma paai\u0161kinim\u0173 akcentavo tiesiogin\u012f l\u0105steli\u0173 u\u017ekr\u0117tim\u0105 arba nauj\u0173 viruso daleli\u0173 i\u0161siskyrim\u0105 \u012f aplink\u0105. Nauji duomenys leid\u017eia \u012ftarti, kad kai kurie virusai gali i\u0161naudoti pa\u010dius organizmo valymosi mechanizmus.<\/p>\n

Tyr\u0117jai pabr\u0117\u017eia, kad steb\u0117jimai atlikti laboratorin\u0117mis s\u0105lygomis, tod\u0117l dar reik\u0117s patvirtinti, kiek \u0161is rei\u0161kinys reik\u0161mingas \u017emogaus organizme. Jei rezultatai pasitvirtins, ateityje tai gal\u0117t\u0173 pad\u0117ti kurti terapijas, kurios sustiprint\u0173 saug\u0173 mirusi\u0173 l\u0105steli\u0173 pa\u0161alinim\u0105 ir kartu blokuot\u0173 virus\u0173 bandymus pasinaudoti \u0161iuo keliu.<\/p>\n","protected":false},"excerpt":{"rendered":"
