Abstract

In contrast to the results of previous in vitro studies, experimental infection of calves with noncytopathic bovine viral diarrhea virus (ncpBVDV) was found to induce strong alpha/beta and gamma interferon responses in gnotobiotic animals. These responses were associated with depressed levels of transforming growth factor beta (TGF-beta) in serum. The results of this study indicate that the immunosuppression caused by ncpBVDV is not associated with low interferon responses or elevated levels of TGF-beta.

摘要

与之前的体外研究结果相反,在无菌动物中发现,用非细胞病变性牛病毒性腹泻病毒(ncpBVDV)对犊牛进行实验性感染可诱导强烈的α/β和γ干扰素反应。这些反应与血清中转化生长因子β(TGF-β)水平降低有关。本研究结果表明,ncpBVDV引起的免疫抑制与低干扰素反应或TGF-β水平升高无关。
