Non-type 2 inflammation (Non-T2)-mediated asthma is difficult to define due to lack of signature biomarkers. It exists in the absence of T2-high or eosinophilic inflammation and includes neutrophilic and paucigranulocytic subtypes. Several cell types and cytokines, including Th1, Th17, IL-6, and IL-17, contribute to mechanisms of non-T2 asthma. Neutrophil extracellular traps (NETs) and inflammasome activation likely play a role in severe neutrophilic asthma. Several mechanisms lead to uncoupling of airway hyperresponsiveness and remodeling from airway inflammation in paucigranulocytic asthma. Recent research on transcriptomics and proteomics in non-T2 asthma is discussed in this review. Investigations of specific drug therapies for non-T2 asthma have been disappointing, and remain an important area for future clinical studies.
由于缺乏特征性生物标志物，非 2 型炎症（非 T2）介导的哮喘难以定义。它存在于 T2 高或嗜酸性粒细胞炎症缺失的情况下，包括中性粒细胞和寡粒细胞亚型。几种细胞类型和细胞因子，包括 Th1、Th17、IL-6 和 IL-17，有助于非 T2 哮喘的发生机制。中性粒细胞细胞外陷阱（NETs）和炎症小体激活可能在严重中性粒细胞性哮喘中发挥作用。几种机制导致在寡粒细胞性哮喘中，气道高反应性和重塑与气道炎症脱耦联。本文综述了非 T2 哮喘中转录组学和蛋白质组学的最新研究。针对非 T2 哮喘的特定药物治疗的研究令人失望，仍然是未来临床研究的一个重要领域。
