Nem meglep\u0151, hogy ez a kis \u00e1llat egy sor \u00faj k\u00e9rd\u00e9st szabad\u00edtott fel azzal kapcsolatban, hogyan t\u00f6rt\u00e9nhetett az evol\u00faci\u00f3.<\/p>\n

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

Ezen a h\u00e9ten, egy \u00faj kutat\u00e1s, amely a Nature szaklapban jelent meg<\/a>, sokkal t\u00f6bbet \u00e1rult el a tartigr\u00e1dok szupererej\u00e9r\u0151l.<\/p>\n

Takekazu Kunieda \u00e9s tud\u00f3scsoportja a tatigr\u00e1dok genomj\u00e1nak szekven\u00e1l\u00e1sa ut\u00e1n azonos\u00edtott egy feh\u00e9rj\u00e9t, amely v\u00e9di a DNS-t, amikor sug\u00e1rz\u00e1snak teszik ki. Ez a feh\u00e9rje csak a tartigr\u00e1dokban tal\u00e1lhat\u00f3 meg. Kunieda azonban jelenleg azt vizsg\u00e1lja, hogyan lehetne ugyanezt a feh\u00e9rj\u00e9t az emberbe bevinni, \u00e9s hogyan lehetne megv\u00e9deni az emberi DNS-t.<\/p>\n

\u00a0\"Elk\u00e9peszt\u0151 l\u00e1tni, hogy egyetlen g\u00e9n elegend\u0151 ahhoz, hogy emberi sejtek kult\u00far\u00e1j\u00e1ban jav\u00edtsa a sug\u00e1rz\u00e1ssal szembeni toleranci\u00e1t. \u00dagy gondoljuk, hogy ez a feh\u00e9rje fizikai pajzsk\u00e9nt m\u0171k\u00f6dhet, amely megv\u00e9di az emberi DNS-t a t\u00e1mad\u00e1sokt\u00f3l.\"<\/p><\/blockquote>\n

A tartigr\u00e1dok szupererej\u00e9nek titka az, hogy k\u00e9pesek ellen\u00e1llni a sz\u00e9ls\u0151s\u00e9ges kisz\u00e1rad\u00e1snak. A tatigr\u00e1dok k\u00e9pesek t\u00fal\u00e9lni mind\u00f6ssze 1% v\u00edzzel, majd \u00fagy t\u00e9rnek vissza az \u00e9letbe, mintha mi sem t\u00f6rt\u00e9nt volna. Kunieda szerint a tartigr\u00e1dok kis darabokra osztj\u00e1k DNS-\u00fcket, \u00e9s \u00e9lettev\u00e9kenys\u00e9g\u00fcket 0,01%-re cs\u00f6kkentik. Amint \u00fajra elrejt\u0151znek, a DNS megjav\u00edtja mag\u00e1t, \u00e9s az \u00e9letaktivit\u00e1suk ism\u00e9t 100%-re emelkedik.<\/p>\n

A genomszekven\u00e1l\u00e1s arra is utal, hogy a tartigr\u00e1dok g\u00e9njeinek t\u00f6bbs\u00e9ge m\u00e1s \u00e1llatokt\u00f3l sz\u00e1rmazik, egy \"horizont\u00e1lis g\u00e9n\u00e1tvitel\" nev\u0171 folyamat r\u00e9v\u00e9n. \u00cdme egy infografika, amely \u00f6sszefoglalja Kunieda kutat\u00e1sait:<\/p>\n

A tatigr\u00e1dok tal\u00e1n nem t\u0171nnek \u00e9rdekes tanulm\u00e1nyi t\u00e1rgynak. Ha azonban feltessz\u00fck a megfelel\u0151 k\u00e9rd\u00e9st, valami elk\u00e9peszt\u0151 dolgot tal\u00e1lhatunk, p\u00e9ld\u00e1ul az \u00e1llatok szuperk\u00e9pess\u00e9geit.<\/p>\n
