Cercet\u0103torii de la Stanford Medicine au raportat un progres major care ar putea schimba modul \u00een care este tratat\u0103 osteoartrita, folosind o injec\u021bie care regenereaz\u0103 cartilajul uzat \u00een articula\u021biile genunchiului, afectate de v\u00e2rst\u0103 sau traumatisme, scrie SciTechDaily<\/a><\/span>.<\/p>\n

Terapia ac\u021bioneaz\u0103 asupra proceselor biologice ale \u00eemb\u0103tr\u00e2nirii, reface cartilajul \u0219i previne artrita, nu se doar limiteaz\u0103 la reducerea durerii sau a inflama\u021biei, a\u0219a cum arat\u0103 experimentele pe animale.<\/p>\n

\u021aintirea \u00eemb\u0103tr\u00e2nirii, nu doar a simptomelor<\/h2>\n

Osteoartrita afecteaz\u0103 aproximativ unul din cinci adul\u021bi \u0219i, \u00een prezent, nu exist\u0103 tratamente care s\u0103 poat\u0103 inversa distrugerea articular\u0103.<\/p>\n

Noua abordare blocheaz\u0103 o protein\u0103 asociat\u0103 \u00eemb\u0103tr\u00e2nirii, numit\u0103 15-PGDH, care cre\u0219te \u00een timp \u0219i contribuie la degradarea \u021besuturilor.<\/p>\n

Prin inhibarea acesteia, cercet\u0103torii au restabilit cartilaj gros \u0219i func\u021bional la \u0219oareci v\u00e2rstnici \u0219i au prevenit artrita dup\u0103 leziuni ale genunchiului similare rupturilor de ligament \u00eencruci\u0219at anterior (LIA).<\/p>\n

Spre deosebire de terapiile existente, tratamentul ac\u021bioneaz\u0103 asupra cauzei biologice de baz\u0103 a pierderii cartilajului.<\/p>\n

Articula\u021biile tratate au prezentat o mobilitate mai bun\u0103 \u0219i inflama\u021bie redus\u0103 comparativ cu cele netratate, suger\u00e2nd un efect real de modificare a bolii.<\/p>\n

Regenerarea cartilajului f\u0103r\u0103 celule stem<\/h2>\n

Un rezultat-cheie este faptul c\u0103 regenerarea cartilajului a avut loc f\u0103r\u0103 activarea celulelor stem.<\/p>\n

\u00cen schimb, celulele cartilajului existente, numite condrocite, au fost reprogramate pentru a adopta un profil genetic mai \u201et\u00e2n\u0103r\u201d.<\/p>\n

Aceast\u0103 schimbare a favorizat formarea cartilajului hialin neted, \u00een locul fibrocartilajului mai slab, frecvent \u00eent\u00e2lnit \u00een artrit\u0103.<\/p>\n

\u201eAceasta reprezint\u0103 o modalitate fundamental nou\u0103 de regenerare a \u021besuturilor adulte\u201d, a declarat Helen Blau, coautoare a studiului.<\/p>\n

\u021aesutul uman arat\u0103 un poten\u021bial similar<\/h2>\n

Cercet\u0103torii au testat terapia \u0219i pe cartilaj uman de genunchi, ob\u021binut \u00een timpul opera\u021biilor de \u00eenlocuire articular\u0103.<\/p>\n

Dup\u0103 o s\u0103pt\u0103m\u00e2n\u0103 de tratament, \u021besutul a prezentat markeri redu\u0219i de degradare \u0219i semne de regenerare activ\u0103, rezultate similare celor observate la animale.<\/p>\n

Cercetarea, publicat\u0103 \u00een revista Science, sugereaz\u0103 c\u0103 abordarea ar putea \u00eent\u00e2rzia sau chiar elimina necesitatea protezelor articulare.<\/p>\n

O versiune sub form\u0103 de pastil\u0103 se afl\u0103 deja \u00een studii clinice timpurii pentru sl\u0103biciunea muscular\u0103 asociat\u0103 v\u00e2rstei, aliment\u00e2nd speran\u021ba c\u0103 vor urma \u0219i teste dedicate regener\u0103rii cartilajului.<\/p>\n","protected":false},"excerpt":{"rendered":"
