CAR-T mō te Glioblastoma

Pūtau CAR-T
Ko te rongoā CAR-T (Chimeric Antigen Receptor T-cell) he momo rongoā ārai mate hou. Kei roto ko te whakarerekē i ō ake pūtau-T—he momo pūtau ārai mate—kia mōhio ai, kia whakaeke ai hoki i ngā pūtau matepukupuku e whakaatu ana i ngā tohu motuhake. Mō te glioblastoma, ko te whāinga o tēnei rongoā he whakarato i tētahi maimoatanga whaiaro ka taea pea te whakaroa i te oranga me te whakamamae i ngā tohu, inā koa ka honoa ki ētahi atu momo rongoā.
Ngā Whāinga i roto i te Whakaora CAR-T mō te Glioblastoma
I roto i te glioblastoma, ko ētahi pūmua kei runga i te mata o ngā pūtau pukupuku he tino pai mō te rongoā CAR-T nā te nui rawa o te whakaaturanga ki ngā pūtau matepukupuku me te iti o te kitea ki ngā kiko hauora. I Bioocus, e rua ngā whāinga matua e arotahi ana mātou:
- GD2He antigen glycolipid tēnei e kitea whānuitia ana i ngā pūtau glioblastoma, me ētahi atu pukupuku roro pērā i ngā glioma midline diffuse. Kei roto te GD2 i te tohu pūtau, ā, he nui te whakaaturanga i roto i ngā pukupuku kaha, ā, he tohu pai mō te arotahi ārai mate.
- B7-H3E mōhiotia ana ko CD276, ka nui rawa te whakaputanga o tēnei pūmua ārai mate i roto i te glioblastoma, ā, ka whai wāhi ki te karo i te mate pukupuku i roto i te pūnaha ārai mate. He mahi tāna ki te whakatairanga i te tipu o te mate pukupuku me te pehi i ngā urupare ārai mate, ā, he whainga whai hua tēnei mō te whakarei ake i ngā whakaekenga pūtau-T.
Mā te hanga i ngā pūtau CAR-T kia kitea ai a GD2, a B7-H3 rānei, ka arotahi te rongoā ki te whakaeke i ngā pūtau pukupuku me te whakaiti i te kino ki ngā kiko roro noa.
Te Mahi a te Whakaora CAR-T: Te Tikanga Mahi
Ka tīmata te rongoā CAR-T mā te kohikohi i tētahi tauira o ō pūtau-T mā roto i tētahi tukanga rite ki te tuku toto. Kātahi ka whakarerekētia ngā ira o ēnei pūtau i roto i tētahi taiwhanga hei whakaatu i tētahi kaiwhakawhiwhi antigen chimeric (CAR)—he kaiwhakawhiwhi ritenga e mahi ana pērā i te "pūrere hopu" mō ngā pūtau matepukupuku.
- Te WhakamihiKa herea te CAR i runga i ngā pūtau-T ki te GD2, ki te B7-H3 rānei i runga i ngā pūtau glioblastoma, he rite tonu ki te raka me te kī.
- WhakahohengaKia herea, ka whakaohokia e te CAR ngā pūtau-T kia whakahohe, kia whakanuia, kia tukuna hoki ngā ngota tohu e whakakotahi ana i ētahi atu pūtau ārai mate kia uru atu ki te pakanga.
- whakangaromangaKa whakaekea tika, ka patua hoki e ngā pūtau-T kua whakahohehia ngā pūtau matepukupuku kua tohua, ka ārahi pea ki te whakaiti i te puku me te whakaiti i te taumahatanga o te mate.
Ko te tikanga o tēnei tukanga ko te werohanga i ngā pūtau-T kua whakarerekētia ki roto i tō tinana, mā roto i ngā tikanga tuku ā-uaua, i ngā tikanga tuku hāngai rānei kia tae atu ki te roro. Ko te whāinga he waihanga i tētahi urupare ārai mate pumau e aroturuki tonu ana, e whakakore ana hoki i ngā pūtau matepukupuku e toe ana i roto i te wā.
Ko ā mātou maimoatanga CAR-T e aro ana ki GD2 me B7-H3 mō Glioblastomawhakaatu i te whai huatanga whakamīharo i roto i ngā whakamātautau haumanu.
Mō GD2 CAR-T, i whakaatuhia e tētahi rangahau o ngā tūroro 37 me ngā glioma taumata-teitei kua hoki whakamuri, kua ātete rānei ki te 72% te auau urupare whāinga, me 42% i tutuki te murunga katoa i te 6 wiki, ā, 56% i mau tonu i te 1.7 tau o te whai muri i te maimoatanga..
Mō B7-H3 CAR-T, i roto i tētahi whakamātautau o te 39 pakeke me te glioblastoma e hokihoki mai ana, i kōrerohia he 30–40% te auau urupare me 60–70% te auau whakahaere mate, me ko te oranga toharite he 11 marama (whakaora kotahi) me te 13.6 marama (whakakotahi), e hipa ana i ngā raraunga o mua.
He haumaru ngā maimoatanga e rua, he ngawari noa iho ngā pānga taha, ā, he ngāwari hoki te whakahaere. E whakapau kaha ana a Bioocus ki te whakatairanga i ēnei maimoatanga auaha hei whakapai ake i ngā putanga mō ngā tūroro glioblastoma.
Te Whakaora Irahiko
Te rongoā irahiko stereotactic (SRT) rānei te rongoā irahiko tinana stereotactic (SBRT) ka taea te whakakotahi me te CAR-T hei arotahi tika ki ngā wāhi pukupuku, hei whakaiti i te rahi me te whakarei ake i te urunga atu o ngā pūtau ārai mate. Ka whakaitihia e tēnei tikanga tino tika te kino ki ngā kiko hauora, ā, ka whakapai ake pea i te urunga atu o te CAR-T.
Ngā Tukanga Wawaotanga
Te whakaurunga matūriki ko te whakauru tika i ngā matūriki irahiko ki roto i te pukupuku mō te irahiko ā-rohe, hei tāpiri atu ki te CAR-T mā te whakaiti i ngā pūtau matepukupuku i mua. Mō te urunga ki te roro, Te puna wai o Ommaya Mā te whakatakotoranga ka taea te tuku tika i te rongoā ki roto i te wai cerebrospinal, ā, ka taea te whakanui ake i te tohatoha CAR-T.
Te Puna Wai o Ommaya
Ko tēnei taputapu motuhake, ka whakatakotoria ki raro i te tumuaki mā te pokanga, ka taea te tuku tika i ngā rongoā ki roto i te wai cerebrospinal mā te catheter ki ngā ventricles o te roroMō ngā tūroro glioblastoma, inā koa ko te hunga e horapa ana te leptomeningeal, Mā te puna wai o Ommaya ka taea te whakahaere tika i ngā pūtau CAR-T, i ētahi atu maimoatanga rānei, kia nui ake ai te kukū o te rongoā i roto i te pūnaha io matua me te iti rawa o te mamae ki te whakaritea ki ngā poka o te hope.
Ko te whāinga o tēnei rautaki maha-ahurea ko te whakanuia te whakahaere i te mate me te tautoko i tō oranga me tō oranga ngākau.
