Senescentceller er kjent for \u00e5 f\u00e5 kroppen v\u00e5r til \u00e5 eldes. Det er helt naturlig, s\u00e5 det er ingen overraskelse. Men ettersom alt i organismen v\u00e5r henger sammen, ser det ut til at aldrende celler kan p\u00e5virke mye mer enn vi tidligere har trodd. Faktisk kan de spille en st\u00f8rre rolle i fremveksten av enkelte sykdommer.<\/p>\n

\"Akkumuleringen av senescentceller i kroppen v\u00e5r har stor innvirkning p\u00e5 levetiden v\u00e5r - noe studier p\u00e5 mus tyder p\u00e5.\" Science Magazine<\/a><\/p><\/blockquote>\n

\"Senescent<\/a><\/p>\n

Det positive er at aldrende celler slutter \u00e5 reprodusere seg, noe som forhindrer at vi utvikler kreft fra celler som ikke er friske nok til \u00e5 reprodusere seg. Allikevel finnes det fortsatt aldrende celler i kroppen, og de kan bli v\u00e6rende i kroppen i lange perioder.<\/p>\n

Dette er sv\u00e6rt relevant n\u00e5r det er snakk om opphopning av celler og andre stoffer som kan p\u00e5virke kroppens systemer. Nyere studier av hjerte- og karsykdommer har pekt p\u00e5 at aldrende celler kan bidra til utviklingen av \u00e5reforkalkning. N\u00e6rmere bestemt fors\u00f8ker forskerne \u00e5 forst\u00e5 hvilken rolle aldrende celler spiller i plakkdannelsen under utviklingen av \u00e5reforkalkning.<\/p>\n

“Plaques can become lethal if they fracture and trigger blood clots, which can block arteries and lead to a heart attack or stroke. In the mice that eliminated their senescent cells, Van Deursen and colleagues found, plaques carried thicker protective caps and thus were less likely to break.” Science Magazine<\/a><\/p><\/blockquote>\n

\"Senescent<\/a><\/p>\n

Det gjenst\u00e5r fortsatt nye tester f\u00f8r man kan anta at aldrende celler spiller en reell rolle i hjerte- og karsykdommer. Forskerne virker imidlertid sv\u00e6rt begeistret for det nye synet p\u00e5 \u00e5reforkalkning. Jo bedre vi forst\u00e5r hvilke faktorer som er involvert i en bestemt sykdom, jo lettere blir det \u00e5 gripe inn og bremse sykdomsutviklingen.<\/p>\n

Hvis forskerne har rett, kan vi komme til \u00e5 se p\u00e5 alternative m\u00e5ter \u00e5 kurere sykdommer p\u00e5 samtidig som vi forlenger levetiden v\u00e5r.<\/p>\n
