Son 20 y\u0131lda yap\u0131lan bir\u00e7ok ara\u015ft\u0131rma, kanser te\u015fhisi alan ki\u015filerin ilerleyen ya\u015flarda demans geli\u015ftirme riskinin yakla\u015f\u0131k y\u00fczde 25 daha d\u00fc\u015f\u00fck olabilece\u011fini g\u00f6steriyordu. Ancak bu ba\u011flant\u0131n\u0131n nedeni uzun s\u00fcredir bilinmiyordu. \u00c7in\u2019deki Huazhong Bilim ve Teknoloji \u00dcniversitesi ara\u015ft\u0131rmac\u0131lar\u0131, kanser h\u00fccreleri taraf\u0131ndan salg\u0131lanan \u201csistatin C\u201d adl\u0131 bir proteinin bu etkile\u015fimde rol oynayabilece\u011fini a\u00e7\u0131klad\u0131.<\/p>\n
Cell dergisinde yay\u0131mlanan ara\u015ft\u0131rmaya g\u00f6re sistatin C proteini, beynin koruyucu bariyerini a\u015fabiliyor ve demansla ili\u015fkili olan amiloid plaklar\u0131n\u0131n par\u00e7alanmas\u0131n\u0131 sa\u011flayan bir s\u00fcreci tetikleyebiliyor.

Hayvanlar \u00fczerinde yap\u0131lan \u00e7al\u0131\u015fmada; demans riski y\u00fcksek olacak \u015fekilde genetik olarak yeti\u015ftirilen farelerde, sistatin C uygulamas\u0131n\u0131n haf\u0131za ve \u00f6\u011frenme performans\u0131n\u0131 iyile\u015ftirdi\u011fi g\u00f6zlendi.
