摘要 登革病毒( dengue virus, DENV)是一种经蚊虫传播的黄病毒,主要流行于热带及亚热带地区。登革病毒有4种血清型( DENV1、DENV2、DENV3和DENV4),均可引起登革热或有更严重临床表现的疾病,如登革出血热( dengue henor-rhagicfever,DHF)、登革休克综合征( dengue shock syndrome, DSS)[1]等。登革热是一种急性发热性疾病,并伴有头痛、后眼窝丛痛、肌痛、关节痛、皮疹、出血表现和或白细胞减少。登革出血热的主要特征性表现是血小板减少、出血性表现、血浆渗漏迹象;可能导致低血压性休克和死亡[2]。最新统计每年全世界有超过5000万人感染登革病毒,出现登革热症状的案例达到960万[3];近50万人住院,25000人死亡,主要高发于儿童[4]。研究发现登革病毒可逃逸人类免疫应答,尤其是固有免疫应答。本综述旨在介绍宿主干扰素产生和效应,以及登革病毒拮抗干扰素系统分子机制的最新研究进展[5]。
