INGINGO ZOSE N'AMAKURU Y’IBICURUZWA BITANZWE KURI URU RUBUGA BISANZWE KUBONA AMAKURU N'INTEGO Z'UBUREZI.
Ibicuruzwa byatanzwe kururu rubuga bigenewe gusa mubushakashatsi bwa vitro. Mu bushakashatsi bwa vitro (Ikilatini: * mu kirahure *, bisobanura mu bikoresho by'ibirahure) bikorwa hanze y'umubiri w'umuntu. Ibicuruzwa ntabwo ari imiti, ntabwo byemejwe n’ikigo cy’Amerika gishinzwe ibiryo n’ibiyobyabwenge (FDA), kandi ntigomba gukoreshwa mu gukumira, kuvura, cyangwa gukiza indwara iyo ari yo yose y’ubuvuzi, indwara, cyangwa indwara. Birabujijwe rwose n'amategeko kwinjiza ibyo bicuruzwa mumubiri wabantu cyangwa inyamaswa muburyo ubwo aribwo bwose.
Incamake
Osteoarthritis (OA) ni indwara isanzwe idakira ifitanye isano no kwangirika kwa karitsiye, kuvugurura amagufwa ya subchondral, hamwe no gukemura ibibazo bya synovial inflammatory, bikangiza cyane ubuzima bw'abarwayi. Hamwe no kwihuta kw'abasaza, umubare wa OA uragenda wiyongera, bitera umutwaro umuryango n'imiryango.
Igicapo 1 Kugereranya ibintu biranga indwara ya rubagimpande ya rubagimpande na osteoarthritis. Indwara ya rubagimpande irangwa nuburyo bwo gutwika bwahujwe no kuvuka, guhuza n'imiterere, hamwe na tromal autoimmune ibisubizo.
Kwangirika kwa karitsiye ni intambwe ikomeye mu iterambere rya OA. Bitewe n'ubushobozi buke bwo kwikosora bwa karitsiye, ibyangiritse biragoye gukira ubwabyo, biganisha ku ndwara buhoro buhoro. Kubwibyo, kumenya uburyo bwiza bwo gusana ibyangiritse byahindutse ubushakashatsi mubuvuzi bwa OA.
Cartalax ni biofarmaceutical yihariye igamije guteza imbere ibyangiritse. Ibigize byihariye biratandukana bitewe nubushakashatsi butandukanye nuburyo bwo gukora, ariko mubisanzwe burimo ibintu byinshi bioaktike, ibice bya matrixique idasanzwe, nibikoresho byabatwara. Muri ibyo, ibintu bioaktike nko guhindura ibintu bikura-β (TGF-β) hamwe na insuline imeze nkikura-1 (IGF-1) bigira uruhare runini muguhuza ikwirakwizwa ryingirabuzimafatizo, gutandukanya, hamwe na synthesis ya matrix idasanzwe. Ibice bya matrixe idasanzwe nka kolagen na acide ya hyaluronike bitanga ubufasha bwumubiri kuri chondrocytes kandi bikagira uruhare mukugenzura ingirabuzimafatizo, kwimuka, no guhererekanya ibimenyetso. Ibikoresho byabatwara bifasha gukusanya no gukomeza-kurekura ibice bioaktike, bikomeza gukora neza aho byakomeretse.
Uruhare rwa Cartalax mugukosora ibikomere bya Cartilage
(1) Guteza imbere Ikwirakwizwa rya Chondrocyte no Gutandukana
Ibintu bikomoka kuri bioaktike muri Cartalax, nka TGF-β na IGF-1, bikora inzira yerekana ibimenyetso muri chondrocytes, bigatera imbere kwizunguruka ryimikorere kandi bigafasha chondrocytes kuva mubyiciro bituje bikagera mubyiciro byinshi. TGF-β ihuza reseptor ya selile kugirango ikore inzira yerekana ibimenyetso bya Smad, igenga imvugo ya poroteyine zifitanye isano na selile, bityo biteza imbere synthesis ya ADN no kugabana muri chondrocytes. Ku rundi ruhande, IGF-1, ibuza chondrocyte apoptose ikoresheje inzira ya PI3K-Akt na MAPK yerekana inzira mu gihe iteza imbere ikwirakwizwa ry'utugari, kongera umubare wa chondrocytes, no gutanga isoko ihagije ya selile yo gusana karitsiye.
Mugihe cyiterambere rya osteoarthritis, phenotype ya chondrocytes ikunda guhinduka, irangwa no kugabanya synthesis ya chondrospecific matrix yibigize ubwoko bwa II kolagen na proteoglycans, hamwe no kongera synthesis yubwoko bwa I kolagen na matrix metalloproteinase (MMPs), biganisha kumitsi ya karitsiye. Cartalax irashobora kugumana fenotipiki isanzwe ya chondrocytes muguhindura ibimenyetso byimikorere yimikorere yimikorere ya gene, ikomeza fenotipiki isanzwe ya chondrocytes. TGF-β irashobora kugenzura imvugo ya gene SOX9, nikintu cyingenzi cyandikirwa mu ntera iteza gene iyandikwa ryubwoko bwa II kolagen na proteoglycans, bityo bikagumana ubushobozi bwa chondrocytes bwo guhuza ibice bya matrise yihariye. Bimwe mubice bigize Cartalax birashobora kandi kubuza imvugo ya MMPs, kugabanya kwangirika kwa matrice idasanzwe, no kurinda ubusugire bwimitsi ya karitsiye.
(2) Amabwiriza ya matrix metabolism idasanzwe
Matrix idasanzwe ni igice cyingenzi cyingirangingo, igizwe ahanini na kolagen, proteoglycans, na fibre elastique. Cartalax iteza imbere synthesis yibi bikoresho bya matrix idasanzwe ikora inzira ya anabolike yerekana inzira muri chondrocytes. Usibye TGF-β-yunganirwa mu kuzamura ubwoko bwa II kolagen hamwe na proteoglycan synthesis, ibindi bintu bikura muri Cartalax, nka fibroblast growth factor (FGF), birashobora kandi gukorera hamwe kugirango bikangure chondrocytes kugirango ihuze matrise idasanzwe. FGF yongerera imbaraga intungamubiri za poroteyine muri chondrocytes, igateza imbere no gusohora kwa molekile nini nka kolagen na proteoglycans, bityo bikongerera ibikubiye muri matrice idasanzwe no kunoza imiterere ya biomehanike ya karitsiye.
Mugihe cyo gusana ibikomere bya karitsiye, kuvugurura matrice idasanzwe ni inzira ikomeye. Cartalax ntabwo iteza imbere gusa synthesis ya matrice idasanzwe ahubwo inagenga imikorere yayo. Irabigeraho muguhuza uburinganire hagati ya matrix metalloproteinase (MMPs) na inhibitor za tissue (TIMPs). Cartalax ibuza ibikorwa bya MMPs, kugabanya kwangirika gukabije kwa matrise idasanzwe; iteza imbere imvugo ya TIMPs, ikongerera imbaraga zo kubuza MMPs, bityo igakomeza kuringaniza ugereranije hagati ya synthesis no gutesha agaciro matrice idasanzwe, ifasha gusana no kuvugurura gahunda ya karitsiye.
(3) Ingaruka zo kurwanya inflammatory
Ibisubizo bitwika bigira uruhare runini mugutangira no gutera imbere kwa OA. Cartalax ifite ibintu bimwe na bimwe birwanya inflammatory kandi irashobora kugenga imvugo ya cytokine ikongora. Muri microen ibidukikije yangiza, Cartalax irashobora kubuza gukora cytokine itera inflammatory nka tumor necrosis factor-α (TNF-α) na interleukin-1β (IL-1β), mugihe hagenzurwa imvugo ya cytokine irwanya inflammatory nka interleukin-10 (IL-10), bityo bikagabanya gusana hamwe na microla ibidukikije.
Gukoresha Cartalax mu kuvura Osteoarthritis
(1) Ubushakashatsi bw'inyamaswa
Mu bushakashatsi bw’inyamaswa, abashakashatsi bashizeho uburyo butandukanye bw’inyamanswa za OA, nk’imbeba ya OA iterwa na transigate ligament transection (ACLT) hamwe n’urukwavu OA rwatewe na papain, kugira ngo basuzume imikorere ya Cartalax mu gusana ibyangiritse. Ibisubizo byubushakashatsi byagaragaje ko nyuma yo gutabara kwa Cartalax, isesengura ryamateka ryerekanye iterambere ryinshi muburyo bworoshye bwa karitsiye, imiterere ya selile, hamwe nibice bya matrice idasanzwe. Amanota yangiritse ya karitsiye mumatsinda yubushakashatsi yagabanutse cyane, byerekana ko Cartalax igabanya neza ubukana bwangirika.
Isesengura ry’ibinyabuzima rya Immunohistochemic na molekuline ryagaragaje urwego rwo hejuru rwerekana imiterere yihariye ya karitsiye kandi igabanya urugero rwimisemburo yangiza nka MMP mu itsinda ryavuwe na Cartalax, bikomeza kwemeza uruhare rwayo mu guteza imbere gusana karitsiye no kugenzura metabolisme idasanzwe.
(2) Ubushakashatsi bwa Clinical
Nubwo Cartalax ikiri mu rwego rwo gushakisha uburyo bwo kuvura, ubushakashatsi bwakozwe mbere y’ubuvuzi bwaravuzwe. Cartalax yerekanwa cyane cyane kubarwayi barwaye osteoarthritis yoroheje kandi yoroheje, cyane cyane abafite ibyangiritse byanduye. Kuri osteoarthritis yo mucyiciro cya mbere, aho kwangirika kwa karitsiye kugarukira, Cartalax irashobora kugabanya umuvuduko witerambere ryindwara no gusana ibyangiritse byangiza ikwirakwizwa rya chondrocyte, kugenga metabolisme ya matrixique idasanzwe, no kugabanya ibisubizo byumuriro. Cartalax irashobora kandi gukoreshwa nkumugereka wokuvura kubaga, gukoreshwa nyuma yo kubagwa arthroscopique cyangwa kubagwa gusana karitsiye kugirango biteze imbere no gusana ingirangingo.
Umwanzuro
Muri make, Cartalax yerekana imbaraga zikomeye mugusana ibyangiritse mu kuvura osteoarthritis. Uhereye ku buryo bwo gukora ibikorwa, biteza imbere ikwirakwizwa ry'utugingo ngengabuzima no gutandukanya, bigenga metabolisme ya matrixique idasanzwe, kandi bigira ingaruka zo kurwanya inflammatory, bityo bigasana kandi bikarinda karitsiye yangiritse ku mpande nyinshi.
