Te Hiranga Hauora o ngā Rōpū Pūmua Oligoclonal i muri i te Whakaora BCMA CAR-T i ngā Tūroro Myeloma Maha

Te Mārama ki ngā Rōpū Pūmua Oligoclonal i roto i te Whakaora CAR-T
I roto Myeloma maha (MM), kua kitea te aroaro o ngā roopu pūmua rerekē (APB), e mōhiotia ana ko ngā roopu pūmua oligoclonal, whai muri i te whakawhitinga pūtau take hematopoietic. Heoi, kāore anō kia mārama te auau me te hiranga haumanu i roto i ngā tūroro e whiwhi ana i te rongoā pūtau CAR-T e arohia ana e BCMA. Hei whakatika i tēnei, i whakahaerehia e ngā kairangahau mai i te Hōhipera Hononga Tuarua o Te Whare Wānanga o Xi'an Jiaotong tētahi rangahau whakamuri hei tātari i te auautanga o te APB, ngā momo, me te hiranga matapae i roto i ngā tūroro MM i rongoatia ki te LCAR-B38M hei wāhanga o te whakamātautau Wāhanga 1 LEGEND-2. Nō nā tata nei i whakaputaina ai ngā kitenga i roto iHemaSphere, i arahina e ngā Ahorangi He Aili, Wang Fangxia, me Bai Ju.

Ngā Kitenga Matua

I arotakehia e te rangahau ngā tūroro e 47, ā, e 23 (48.9%) i pāngia e te APB i muri i te rongoā CAR-T. Ko te momo tino noa ko te IgG (91.3%). Ko te wā toharite ki te tīmatanga o te APB he 3.6 marama i muri i te werohanga CAR-T, ā, ko te roanga toharite he 5.8 marama. He mea nui, i honoa te putanga mai o te APB ki te whakapai ake i ngā urupare maimoatanga, te roa ake o te oranga kore-haere whakamua (PFS), me te whakapai ake i te oranga whānui (OS).

Ko ētahi atu tirohanga i whakaurua ko:

• Ngā Hua Hauora Whakapai AkeI whakaatuhia e ngā tūroro whai APB he pai ake te urupare ki te rongoā LCAR-B38M, ā, i tutuki hoki he murunga hōhonu ake.
• Te Whakaora Ārai Mate Kua WhakapaitiaI whakaatuhia e ngā tūroro APB he nui ake ngā reiti whakaora o ngā immunoglobulin me ngā lymphocytes i te 3 me te 6 marama i muri i te maimoatanga, e tohu ana i te kaha o ngā urupare ārai mate humoral me te hanganga anō o te ārai mate i muri mai.
• Ngā Tohu MatapaeI roto i te tātaritanga maha-taurangi, i kitea te whai huatanga o te rongoā CAR-T, te tatau pereti toto, te aroaro o te APB, me ngā taumata β2-microglobulin hei āhuatanga motuhake mō te matapae i te PFS. Mō te OS, ko te whai huatanga o te CAR-T me te tatau pereti toto ngā āhuatanga motuhake.

He mea whakamere, kāore i kitea e te rangahau he rerekētanga nui i roto i ngā taupori pūtau-T, pūtau-NK rānei i waenga i ngā rōpū APB me ngā rōpū kore-APB, e whakaatu ana ko te uara matapae o te APB ka ahu mai pea i te whakarei ake i te whakaoranga humoral me te ārai mate kaua ki ngā tikanga ārai mate pūtau.

Whakamutunga me ngā Whakatairanga

E whakaatu ana te rangahau ko te noho mai o te APB i muri i te rongoā BCMA CAR-T e hono ana ki ngā murunga hōhonu ake me ngā putanga haumanu pai ake i roto i ngā tūroro MM kua hoki whakamuri/uaua ki te mate. Hei tāpiri, e whakaatu ana ngā kitenga i te APB hei tohu pea mō te whakaora whai hua o te ārai mate i muri i te rongoā, e whakatuwhera ana i ngā huarahi mō ētahi atu rangahau ki te arotau i te rongoā CAR-T me te mārama ki ngā āhuatanga whakaora o te ārai mate.

I te whanaketanga tonu o ngā maimoatanga CAR-T e aro ana ki te BCMA, he mea tino nui ēnei māramatanga ki te whakapai ake i ngā tikanga maimoatanga me te whakapai ake i ngā putanga mō ngā tūroro MM puta noa i te ao.
