Tervise ja elur\u00f5\u00f5mu aluseks on t\u00f5husalt toimivad mitokondrid, v\u00e4ikesed piklikud t\u00f6\u00f6kad kehakesed rakkude sees, mis teevad toiduenergia rakkudele k\u00e4ttesaadavaks. Kui mitokondrid t\u00f5rkuma hakkavad, tunneb inimene v\u00e4simust ja v\u00f5ib j\u00e4\u00e4da haigeks.<\/p>\n

Texase teadlased Ameerika \u00dchendriikidest on n\u00fc\u00fcd leidnud nanotehnoloogilise nipi, kuidas rakud v\u00f5iksid saada endale uusi agaraid mitokondreid.<\/p>\n

On hiljuti avastatud, et rakud saavad mitokondreid \u00fcle v\u00f5tta ka teistelt rakkudelt, aga kui ka naaberrakkude mitokondrid on rikki l\u00e4inud, siis ei ole nonde heanaaberlikust toetusest alati piisavalt abi.<\/p>\n

Akhilesh Gaharwar ja John Soukar Texase A&M \u00dclikoolist leidsid v\u00f5imaluse appi v\u00f5tta t\u00fcvirakud ja v\u00e4ikesed haralised nanoosakesed, niinimetatud nanolilled.<\/p>\n

Nanolilled on molekulide kogumid, mis meenutavad elektronmikroskoobis vaadatuna tihtipeale lille\u00f5isi.<\/p>\n

Oma tiheogalise, tihti r\u00e4gastikulisegi struktuuri t\u00f5ttu on neil v\u00e4ikeses ruumalas rohkesti pinda, mis pakub mitmekesiseid v\u00f5imalusi vastastiktoimeks neid \u00fcmbritsevate molekulidega.<\/p>\n

<\/p>\n

Gaharwar, Soukar ja nende kaaslased tegid katseid nanolilledega, mis koosnesid mol\u00fcbdeendisulfiidist MoS2.<\/p>\n

Nad manustasid neid nanolilli t\u00fcvirakkudele. T\u00fcvirakudes hakkasid mitokondrid seepeale hoogsalt paljunema ja nende arv t\u00f5usis kahekordseks.<\/p>\n

N\u00fc\u00fcd viisid teadlased need t\u00e4iustatud t\u00fcvirakud kontakti kahjustatud v\u00f5i vanaldaste rakkudega, mille enda mitokondrid olid loiuks j\u00e4\u00e4nud.<\/p>\n

Ilmnes, et t\u00fcvirakkudel ei olnud sugugi kahju oma \u00fclearuseid mitokondreid neile kahjustatud v\u00f5i vanaldastele rakkudele loovutada.<\/p>\n

Gaharwar, Soukar ja kaasautorid kirjutavad \u00dchendriikide teadusakadeemia toimetistes<\/a>, et uute mitokondrite j\u00f5ul l\u00f5id n\u00e4rbunud rakud taas \u00f5itsele ja nende toimepidevus taastus.<\/p>\n

Isegi m\u00fcrgised ained, millega teadlased rakke prooviks kostitasid, ei teinud neile enam nii palju kahju.<\/p>\n

Nanolillelise l\u00e4henemise \u00fcks tugev eelis muude senituntud mitokondritaastusv\u00f5tete ees on teadlaste s\u00f5nul lootus, et raviprotseduure saab teha harvemini. Nanolilled on suhteliselt suured ja nad p\u00fcsivad rakkudes kauem kui tavalised ravimained.<\/p>\n

Pildil on nanolilled elektronmikroskoobi all.<\/p>\n
