Te Whakaora CAR-T: He Anamata Pai mō ngā Mate Pukupuku Pūtau-T

Kua hurihia e te rongoā pūtau-T Chimeric Antigen Receptor (CAR-T) te maimoatanga o ngā mate pukupuku pūtau-B, e tuku ana i ngā murunga roa me ngā rongoā mō te tini o ngā tūroro. Nā te whakatenatena o ēnei angitu, kua tahuri ngā kairangahau ki te whakamahi i te CAR-T mō ngā mate pukupuku pūtau-T, tae atu ki Lymphoma Pūtau-Ts (TCL) me te mate pukupuku lymphoblastic acute pūtau-T (T-ALL). Heoi, he wero motuhake ēnei mate pukupuku pūtau-T mō te whanaketanga o te rongoā CAR-T.

Ko ngā mate pukupuku pūtau-T, e whai wāhi nui ana ki ngā mate pukupuku o te tamarikitanga me te pakeke, e mōhiotia ana mō tō rātou kaha ki te whakaeke me te ātete ki ngā maimoatanga tuku iho. He tino rerekē te T-ALL me te TCL, ā, he kino ngā hua i roto i ngā horopaki kua hoki mai, kua ātete rānei (r/r), e whakaatu ana i te hiahia nui mō ngā kōwhiringa maimoatanga hou. Kua aro nui te rongoā CAR-T mō ngā mate pukupuku pūtau-T nā tōna kaha ki te whakarato i tētahi otinga whai hua, whai kiko.

Ko te wero kei roto i te whakaaturanga tahi o ngā whāinga antigen i waenga i ngā pūtau-T kino me ngā pūtau-T noa, ka arahi pea ki te "fratricide," i reira ka whakangaromia e ngā pūtau CAR-T ngā pūtau-T hauora. Hei tāpiri, ko te aplasia pūtau-T, ka waiho i ngā tūroro kia ngoikore ki ngā mate, he tūponotanga nui anō. Ahakoa ēnei arai, kua whakaatuhia e ngā whanaketanga haumanu tata nei ngā hua pai mō te CAR-T i roto i te T-ALL me te TCL.

He arotake tata nei i whakaputaina i roto i Ngā Whakatairanga Toto E whakaatu ana i ētahi whakamātautau haumanu whai hua. Ko tētahi huarahi ko te arotahi ki te CD7, he pūmua e whakaatuhia ana i te mata o te T-ALL me ētahi lymphoma pūtau-T. I roto i ngā whakamātautau wāhanga tuatahi, kua whakaatuhia e ngā maimoatanga CAR-T e arotahi ana ki te CD7 te whai huatanga whakamiharo, me te whakatutuki i te murunga katoa i roto i te maha o ngā tūroro. Hei tāpiri, ko ngā rautaki e arotahi ana ki te whakaiti i te "fratricide" me te whakapai ake i te hanga o ngā pūtau CAR-T kei te whakatakoto i te ara mō ngā putanga haumanu.

Kua whakamātauhia hoki e ngā whakamātautau tata nei te whakatika i ngā pūtau-T hei whakarei ake i te motuhaketanga me te pakari o ngā pūtau CAR-T. Hei tauira, ko te whakamahinga o te hangarau CRISPR-Cas9 ki te arotahi ki ngā antigens motuhake pēnei i te CD5, CD7, me te TRBC kua whakaatu i te kaha ki te whakapai ake i te haumaru me te whai huatanga. E whakaatu ana ngā hua tuatahi ko te rongoā CAR-T, ina hangaia marietia, ka taea te noho hei patu kaha ki ngā mate pukupuku pūtau-T.

Heoi anō, ko te whakakotahi i te rongoā CAR-T me ētahi atu maimoatanga, pērā i te whakawhitinga pūtau take hematopoietic allogeneic (allo-HSCT), kua whakaatu i te tumanako ki te whakaroa i te oranga me te aukati i ngā hokinga mai. I roto i tētahi whakamātautau wāhanga II o te rongoā CAR-T e arohia ana ki te CD7, 63.5% o ngā tūroro i noho i roto i te whakaoranga i muri i ngā tau e rua, ā, ko te hunga i whiwhi allo-HSCT i tino pai ake te oranga kore-haere whakamua (PFS).

I te haere tonu o ngā rangahau, kei te piki haere te pai o te tirohanga mō te rongoā CAR-T i roto i ngā mate pukupuku pūtau-T. Ahakoa he nui tonu ngā wero hei wikitoria, tae atu ki te whakahaere i te mate tukunga cytokine kino (CRS) me te paitini roro, kei te whakawhānui tonu te māramatanga e whanake ana mō te hangarau CAR-T i ōna tono pea.

I BIOOCUS, e whakapau kaha ana mātou ki te noho ki mua i te whanaketanga o te rongoā CAR-T, ā, e harikoa ana mātou ki te tuku i tēnei rongoā hou ki ngā tūroro o te ao katoa. I te whanaketanga tonu o ngā whakamātautau haumanu, e tumanako tonu ana mātou ka whakaratohia e te rongoā CAR-T tētahi kōwhiringa whakaora mō te hunga e pāngia ana e ngā mate pukupuku pūtau-T, ka kawea mai he tumanako hou ki ngā tūroro me ngā whānau e hiahia ana ki ngā kōwhiringa rongoā whai hua.

Mō ētahi atu kōrero e pā ana ki ā mātou kaupapa maimoatanga CAR-T, tirohia tō mātou paetukutuku, whakapā atu rānei ki tā mātou tīma tautoko tūroro.
