We have previously demonstrated that parainfluenza virus type 3 (PIV3), a significant respiratory pathogen, can markedly inhibit T-cell function in vitro. We now report that the virus potently induces interleukin-10 (IL-10) production by peripheral blood mononuclear cells. The IL-10 produced contributes to viral inhibition of T-cell proliferation and protects T cells from PIV3-mediated apoptosis. These findings suggest that IL-10 is likely to play an important immunoregulatory role in PIV3 infections.
我们之前已经证明,3型副流感病毒(PIV3)作为一种重要的呼吸道病原体,在体外能显著抑制T细胞功能。我们现在报告,该病毒能强力诱导外周血单核细胞产生白细胞介素-10(IL-10)。所产生的IL-10有助于病毒对T细胞增殖的抑制,并保护T细胞免受PIV3介导的凋亡。这些发现表明,IL-10可能在PIV3感染中发挥重要的免疫调节作用。
