Te whaitakenga haumanu - Ko nga whakaaturanga pathological, immunological me te haumanu he tino rite ki te mate Guillain-Barre tangata.
Nga pito mutunga — te taumaha o te tinana, te kaute haumanu, te macrophage me te CD4+ te kuhutanga o te pūtau T, te histopathology nerve sciatic (HE, LFB), te tātari cytokine proinflammatory (TNF-α, IL-1β).
Ko te mahi a te miihini —macrophage-mediated demyelination and phagocytosis, CD4+ T cell-driven autoimmune response, closely mimic the pathogenesis of human GBS.
Uara Whakamaori - He pai mo te whakamatautau i nga immunomodulators (IVIG, corticosteroids), hei awhina i nga aukati, me nga rongoa e aro ana ki nga pūtau T, macrophages ranei.
IND Ready Packet – Ka taea te whakahaere rangahau i runga i nga tikanga o te GLP.
• Te whakamatautau i te kaha o nga immunomodulators (IVIG, corticosteroids, plasma exchange mimetics) i te Guillain-Barre syndrome
• Te Aromatawai o nga kai-aukati whakauru me nga aukati FcRn
• Te whakamanatanga whainga mo te wharanga nerve peripheral macrophage me te T-cell-mediated nerve peripheral
• Te kitenga o te tohu koiora (cytokines, autoantibodies, tohu whara neurological)
• Nga rangahau rongoa me te paitini hei tautoko i te IND

Q: Me pehea te SP-26 peptide e akiaki ana i te EAN?
Whakautu: SP-26 e rite ana ki te epitope immunodominant o te pūmua myelin P2 bovine. Ko te mate ka puta he urupare autoimmune i takawaenga e nga pūtau CD4+ T ki te myelin nerve peripheral, me nga macrophages te matua o nga pūtau whai hua ka puta te whakaheke ma te phagocytosis tika me te tukunga o nga kaiwawao mumura.
P: He aha nga tino rite ki te mate Guillain-Barre i roto i te tangata?
A: Ko te EAN e tohuhia ana e te piki haere o te paralysis, te whakaheke i te pathology, te macrophage me te whakaurunga o te pūtau T, me te urupare ki te rongoa immunomodulatory i roto i te GBS tangata. Koinei te tauira kararehe e tino manakohia ana i roto i te rangahau GBS.
P: Ka taea te whakamahi i tenei tauira mo nga rangahau tautoko IND?
Whakautu: Ae. Ka taea te whakahaere rangahau i runga i nga tikanga GLP mo nga tukunga ture (FDA, EMA).
P: Ka tukuna e koe nga tikanga ako kua whakaritea (hei tauira, he rereke nga pota SP-26, pota aukati, me nga pota maimoatanga)?
Whakautu: Ko te akoranga. Ko ta matou roopu pūtaiao he whakarite i te horopeta SP-26, nga tikanga maimoatanga me nga tātaritanga mutunga i runga i to kaitono tarukino motuhake.
