Senesenssisolujen tiedet\u00e4\u00e4n vanhentavan kehoamme. Se on asioiden luonnollinen kulku, joten se ei ole yll\u00e4tys.

Itse asiassa niill\u00e4 saattaa olla suurempi merkitys joidenkin sairauksien syntymisess\u00e4.<\/p>\n

\"Vanhenevien solujen kertyminen elimist\u00f6\u00f6mme vaikuttaa merkitt\u00e4v\u00e4sti elinik\u00e4\u00e4mme - kuten hiirill\u00e4 tehdyt tutkimukset osoittavat.\" Tiede-lehti<\/a><\/p><\/blockquote>\n

Hyv\u00e4 asia on, ett\u00e4 vanhenevat solut lopettavat lis\u00e4\u00e4ntymisen, mik\u00e4 est\u00e4\u00e4 meit\u00e4 kehitt\u00e4m\u00e4st\u00e4 sy\u00f6p\u00e4\u00e4 soluista, jotka eiv\u00e4t ole tarpeeksi terveit\u00e4 lis\u00e4\u00e4nty\u00e4kseen. Ik\u00e4\u00e4ntyvi\u00e4 soluja voi kuitenkin edelleen l\u00f6yty\u00e4 kehostamme ja ne viipyv\u00e4t kehossamme pitk\u00e4\u00e4n.<\/p>\n

T\u00e4m\u00e4 seikka on eritt\u00e4in t\u00e4rke\u00e4, kun aiheena on solujen ja muiden kehon j\u00e4rjestelmiin mahdollisesti vaikuttavien aineiden kertyminen. Syd\u00e4n- ja verisuonitauteja koskevissa viimeaikaisissa tutkimuksissa on nimitt\u00e4in todettu, ett\u00e4 vanhenevat solut voivat vaikuttaa ateroskleroosin kehittymiseen. Tarkemmin sanottuna tutkijat yritt\u00e4v\u00e4t ymm\u00e4rt\u00e4\u00e4, mik\u00e4 on vanhenevien solujen rooli plakkien muodostumisessa ateroskleroosin kehittymisen aikana.<\/p>\n

\"Plakit voivat muuttua tappaviksi, jos ne murtuvat ja laukaisevat verihyytymi\u00e4, jotka voivat tukkia valtimot ja johtaa syd\u00e4nkohtaukseen tai aivohalvaukseen. Van Deursen ja kollegat havaitsivat, ett\u00e4 hiirill\u00e4, jotka eliminoivat vanhenevat solunsa, plakit olivat paksumpia suojapeitteineen ja rikkoutuivat siten harvemmin.\" Tiede-lehti<\/a><\/p><\/blockquote>\n

Uusia testej\u00e4 on viel\u00e4 teht\u00e4v\u00e4, ennen kuin voidaan olettaa, ett\u00e4 ik\u00e4\u00e4ntyvill\u00e4 soluilla on todellinen rooli syd\u00e4n- ja verisuonisairauksissa. Tutkijat vaikuttavat kuitenkin hyvin innostuneilta uudesta n\u00e4k\u00f6kulmasta ateroskleroosiin. Mit\u00e4 paremmin ymm\u00e4rr\u00e4mme tiettyyn sairauteen liittyvi\u00e4 tekij\u00f6it\u00e4, sit\u00e4 helpommin voimme puuttua taudin kehittymiseen ja taantua siit\u00e4.<\/p>\n

Jos tutkijat ovat oikeassa, voisimme etsi\u00e4 vaihtoehtoisia tapoja parantaa sairauksia elini\u00e4n pidentyess\u00e4.<\/p>\n
