The pathogenesis of asthma can be divided into three stages in immunology. The initial stage is sensibilization, which is closely associated with the activation of T cells. B7/CD28 and CD69 also play a significant role in this process. The second stage is chronic allergic inflammation. The immune dysfunction resulting from the disturbance of TH1/TH2 is a major cause of chronic allergic inflammation, and dominates asthma attack. And the third stage is airway remodeling due to chronic inflammation. Airway remodeling is one of the major causes of refractory asthma, which also contributes to the death from asthma.

哮喘的发病从免疫学角度可以分为三期：初期为致敏阶段，与T细胞激活关系密切，B7/CD28和CD69在这一过程也扮演重要角色；第二期为慢性过敏性炎症阶段，TH1/TH2失衡导致免疫功能紊乱是此阶段的主要原因，在哮喘发作过程中起主要作用；第三期为慢性炎症引起的气道结构重构阶段，是难治性支气管哮喘的重要发病和死亡原因。

Viral vector mainly contain adenovirus, retrovirus,adeno-associated virus and so on, but it has potential danger of safety; it isrepeled by immune system when it is injected to organism for a greatimmunogenicity. An injection with adenovirus vector with highconcentration, it leads to serious inflammatory reaction of liver. Viralvector such as liposome and polycation are commonly used lately. But,liposome and polycation have low specificness and targetness of genetransfer tissue, have lower transfection efficiency and short period ofgene expression, for they can be phagocytized by endothelial system.

许多的载体，病毒载体和非病毒载体以前已广泛应用，病毒载体主要包括腺病毒，逆转录病毒，腺相关病毒等；但病毒载体在安全性方面存在潜在的危险；免疫原性比较强，注射到机体后很快会被机体的免疫系统排斥，当静脉注射高浓度的腺病毒载体会使肝脏发生严重的炎症反应；非病毒载体目前常用的有脂质体及多聚阳离子聚合物；但脂质体和阳离子聚合物介导基因转移缺乏组织的特异性和靶向性，转染效率较低且易被网状内皮系统吞噬，基因表达时间短；因此研制新型的非病毒载体已成为研究的热点，纳米颗粒具有小尺寸效应，表面效应，随着颗粒直径变小，比表面积将会显著增大，故具有很高的化学活性，因而纳米成为了最有应用前景的非病毒载体。
