(A) Both Th1 and Th 17-driven inflammation can lead to airway obstruction and exacerbate an asthma phenotype: 這是正確的。Th1和Th17皆可引起氣道阻塞和加重氣喘症狀。Th1通常透過產生IFN-gamma等細胞因子進行工作,而Th17則主要透過產生IL-17。(B) IL-1 could contribute to asthma phenotype by causing airway hyperresponsiveness, by recruiting neutrophils: IL-1是一種促炎性細胞因子,參與多種炎症和疾病的發病機制。然而,在氣喘的上下文中,將IL-1直接與氣道超反應性和中性粒細胞招募相關聯可能不是非常精確。儘管IL-1可能與這些反應有某些關聯,但它不是氣喘中最主要的細胞因子。因此,這個選項是不正確的。(C) Th 17 activity has positive correlation with asthma severity: 這是正確的。Th17的活動已經與氣喘的嚴重性呈正相關。Th17細胞產生的IL-17可以招募中性粒細胞,這在某些非Th2型氣喘中是重要的。(D) Th 17-mediated inflammation may coexist with Th2-high phenotype and augment Th2 response: 這也是正確的。Th17介導的炎症可以與Th2高表型共存。在某些情況下,Th17和Th2反應可以共同作用,導致更加嚴重的炎症。
