PLOS ONE:禽类传染性支气管炎病毒的发病机制

禽传染性支气管炎病毒(IBV)主要在鸡的上呼吸道上皮细胞中复制,诱导形态学和免疫调节变化。

然而,IBV诱导的局部免疫应答与发病机制之间的关系尚未完全阐明。

近期,一项研究比较了来自相同基因型IBV的两个巴西野外分离物(A和B)攻击后气管样品中与免疫应答相关的基因表达谱,并分析了这些应答与病毒复制和气管及肾脏的病理变化。

结果显示,TLR7途径的早期激活受到抑制,随后与IBV A分离株的攻击相比,用IBV B分离株攻击诱导的炎症相关基因的表达水平较低。用B分离株攻击鸟的气管样品中,细胞介导的免疫(CMI)相关基因也呈现较低水平的表达。

在暴露于IBV B分离株攻击的鸡的气管和肾样品中,观察到病毒载量增加,且发生病变的鸟的数目比例增加。

在IBV B分离株攻击后,发生的早期免疫应答的模式不同,这与TLR7的下调相关,导致促炎反应不足,CMI应答降低,这似乎也与严重的肾损伤相关,并且增强这种分离株在鸡中的复制的能力。
