E tika ana mo te haumanu – Ko te paohu hikareti me te whakakitenga LPS he rite ki te mate COPD tangata me te mumura mau tonu.
Momo maha – E waatea ana nga tauira kiore me te kiore kia rite ki nga whakaritenga whakamatautau rereke (nga taputapu ira me te rahi ake).
Nga pito mutunga - Te taumaha o te tinana, te BALF cytology (WBC, macrophages, monocytes), mahi pūkahukahu (tautoko, tautuku), histopathology (HE scoring), cytokine profiling.
Te uara whakamaori - He pai mo te whakamatautau i nga raau taero anti-inflammatory (corticosteroids, PDE4 inhibitors), bronchodilators, me te mucolytics.
Nga kohinga raraunga kua rite IND - Ka taea te whakahaere rangahau i runga i nga tikanga o te GLP.

• Te whakamatautau kaha o nga raau taero anti-inflammatory (corticosteroids, PDE4 inhibitors, p38 MAPK inhibitors)

P: He aha te take i whakakotahi ai te paoa hikareti me te LPS ki te tauira COPD?
A: Ko te paoa hikareti ka whakapataritari i te mumura roa me te emphysema, ko te LPS (te peehi i te mate huakita) ka whakapakeke i te mumura o te hau me te hanga hūpē. Ko te whakakotahitanga ka kaha ake te whakahoki i te pathology COPD tangata, tae atu ki te whakakaha kino.
Q: He aha nga mea tino rite ki te COPD tangata?
A: Ko nga tauira e whakaatu ana i te arai o te rere o te hau, te mumura o te ara (macrophages, neutrophils), te emphysema, te metaplasia pūtau kaata, me nga paanga o te punaha, he rite tonu ki te COPD tangata.
P: Ka taea te whakamahi i enei tauira mo nga rangahau whakaahei IND?
A: 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 te roanga o te puhipuhi auahi, nga pota LPS)?
A: Tino. Ko ta matou roopu putaiao e whakahiato i nga tikanga whakamaarama mo te auahi, te whakangao LPS, me nga tātaritanga mutunga ki to kaitono tarukino motuhake.
