A group of hamsters (n = 25) was intranasally infected with equine herpesvirus-9 (EHV-9) and mRNA transcription levels of several proinflammatory (IFN-γ, TNF-α and IL-6) and anti-inflammatory (IL-4, IL-10 and TGF-β) cytokines were investigated in brain tissue using RT-qPCR. These levels were correlated with the severity of sequential histopathological changes and intensity of immunohistochemical labelling of virus antigen in brain. Early and progressive upregulation of all the proinflammatory and anti-inflammatory cytokines investigated (P < 0.05) was correlated with increasing severity of encephalitis and viral antigen expression from 2 days post infection (dpi) with a peak at 4-5 dpi (P <0.05).
一组仓鼠(n=25)经鼻腔感染马疱疹病毒 9 型(EHV-9),使用 RT-qPCR 检测脑组织中几种促炎(IFN-γ、TNF-α 和 IL-6)和抗炎(IL-4、IL-10 和 TGF-β)细胞因子的 mRNA 转录水平。这些水平与脑组织中病毒抗原的组织病理学变化严重程度和免疫组化标记强度相关。所有研究的促炎和抗炎细胞因子均呈早期和进行性上调(P<0.05),与从感染后 2 天(dpi)开始的脑炎严重程度和病毒抗原表达逐渐增加相关,在 4-5dpi 时达到峰值(P<0.05)。
