Naukowcy z Uniwersytetu Przyrodniczego we Wroc\u0142awiu i Instytutu Niskich Temperatur i Bada\u0144 Strukturalnych Polskiej Akademii Nauk, zamierzaj\u0105 odwr\u00f3ci\u0107 proces resorpcji ko\u015bci. Opracowana przez nich technologia mo\u017ce zrewolucjonizowa\u0107 leczenie osteoporozy \u2013 informuje Uniwersytet Przyrodniczy.<\/p>\n

Na osteoporoz\u0119 choruje co trzecia kobieta po okresie przekwitania \u2013 ryzyko z\u0142amania ko\u015bci u pa\u0144 oscyluje wok\u00f3\u0142 40 proc., u m\u0119\u017cczyzn oko\u0142o 13\u201322 proc. Ta choroba metaboliczna ko\u015bci charakteryzuje si\u0119 nisk\u0105 mas\u0105 kostn\u0105, upo\u015bledzon\u0105 mikroarchitektur\u0105 tkanki kostnej, a w konsekwencji zwi\u0119kszon\u0105 jej \u0142amliwo\u015bci\u0105 i podatno\u015bci\u0105 na z\u0142amania. W pocz\u0105tkowej fazie choroba przebiega bezobjawowo \u2013dlatego nazywana jest cichym z\u0142odziejem ko\u015bci.<\/p>\n

Osteoporoza jest chorob\u0105 spo\u0142eczn\u0105, a wi\u0119c tak\u0105, kt\u00f3ra jest istotna nie tylko z powodu skali, ale te\u017c koszt\u00f3w ekonomicznych \u2013 t\u0142umaczy prof. Krzysztof Marycz z Uniwersytetu Przyrodniczego we Wroc\u0142awiu, kt\u00f3ry wykorzystuj\u0105c technologi\u0119 mRNA, stworzy biomateria\u0142, dzi\u0119ki kt\u00f3remu mo\u017cliwe b\u0119dzie zahamowanie procesu rzeszotowienia ko\u015bci i doprowadzenie do odbudowy brakuj\u0105cego materia\u0142u kostnego.<\/p>\n

W projekcie, kt\u00f3ry zdoby\u0142 najwy\u017csze finansowanie w konkursie Tango 5 Narodowego Centrum Bada\u0144 i Rozwoju, naukowiec wroc\u0142awskiej uczelni zaproponowa\u0142 wykorzystanie technologii nieorganicznej do ochrony cz\u0105steczek organicznych: mRNA ma hamowa\u0107 osteoklasty (kom\u00f3rki \u201ezjadaj\u0105ce\u201d ko\u015b\u0107) i promowa\u0107 osteoblasty (buduj\u0105ce i umo\u017cliwiaj\u0105ce deponowanie wapnia w ko\u015bci) w miejscu ubytku.<\/p>\n

Nowatorstwo metody polega m.in. na precyzji umiejscowienia tego procesu i jego regulacji. Biomateria\u0142 z mRNA zostanie bowiem wprowadzony w miejsce konkretnego ubytku, a lekarz b\u0119dzie sterowa\u0142 kolejno\u015bci\u0105 aktywacji: najpierw b\u0119d\u0105 si\u0119 otwiera\u0107 mikrokapsu\u0142ki z mRNA, kt\u00f3re zahamuje osteoklasty, a potem b\u0119d\u0105 si\u0119 otwiera\u0107 kolejne \u2013 tym razem z mRNA, kt\u00f3re pobudzi osteoblasty do dzia\u0142ania.<\/p>\n
