Regulation of the lectin galectin 9 (Gal-9) was investigated for the first time during human cytomegalovirus (HCMV) infection. Gal-9 transcription was significantly upregulated in transplant recipients with reactivated HCMV in vivo. In vitro, Gal-9 was potently upregulated by HCMV independently of viral gene expression, with interferon beta (IFN-β) identified as the mediator of this effect. This study defines an immunoregulatory protein potently increased by HCMV infection and a novel mechanism to control Gal-9 through IFN-β induction.
首次在人巨细胞病毒(HCMV)感染期间研究了凝集素半乳糖凝集素9(Gal-9)的调节情况。在体内HCMV重新激活的移植受者中,Gal-9转录显著上调。在体外,HCMV可独立于病毒基因表达强力上调Gal-9,其中干扰素β(IFN-β)被确定为这种效应的介质。本研究确定了一种因HCMV感染而强力增加的免疫调节蛋白,以及一种通过IFN-β诱导来控制Gal-9的新机制。
