Article Abstract

is one member of the sirtuin family proteins with NAD (NAD)-dependent histone deacetylase activity. In this study, we report that zebrafish is induced upon viral infection, and overexpression of suppresses cellular antiviral responses. Disruption of in zebrafish increases the survival rate upon spring viremia of carp virus infection. Further assays indicate that sirt7 interacts with irf3 and irf7 and attenuates phosphorylation of irf3 and irf7 by preventing tbk1 binding to irf3 and irf7. In addition, the enzymatic activity of sirt7 is not required for to repress IFN-1 activation. To our knowledge, this study provides novel insights into function and sheds new light on the regulation of and by attenuating phosphorylation.

Sea perch is one of the most important fish species farmed in China. However, the frequent outbreak of viral diseases induced by sea perch iridovirus (SPIV) always caused high mortality and heavy economic losses in sea perch aquaculture. Up to now, no effective countermeasures against SPIV infection have been established.

Interferon regulatory factor 3 (IRF3) is the first transcription factor activating the expression of type I interferons (IFN-I). It is present in the cytoplasm of most cell types under basal conditions and its activation by phosphorylation allows a rapid triggering of the IFN-I pathway in response to viral infection. This activation of IFN-I is amplified by IRF7, the other major IFN-I transcription factor which expression is induced, in most cell types, by the interferon response.

Interferon regulatory factor 7 (IRF7) is a master transcriptional regulator of innate immunity. IRF7 binds as a homodimer, or heterodimer with IRF3, to promoters of type I interferons (IFN-Is) to drive their expression, which activates expression of antiviral genes. Here, we demonstrate that alternative splicing of the first intron within the coding region of human IRF7 is regulated across immune tissues and in response to immunologic stimuli.

Background: The therapeutic efficacy of oncolytic vaccinia virus (JX-594) has been demonstrated in metastatic clear cell renal cell carcinoma (ccRCC); however, only selected patients respond, and there are no predictive biomarkers for therapeutic response. We aimed to identify predictive biomarkers for JX-594 treatment and elucidate the underlying mechanisms.

Methods: Four cell line-derived xenograft (CDX) models were developed using representative ccRCC cell lines harboring common mutations.

The First Affiliated Hospital of Chongqing Medical University, Chongqing Key Laboratory of Ophthalmology, Chongqing Eye Institute, Chongqing Branch (Municipality Division) of National Clinical Research Center for Ocular Diseases, Chongqing 400016, China.

Aim: To investigate the expression of interferon regulatory factors (IRFs) in peripheral blood mononuclear cells (PBMCs) of patients with Sjögren's syndrome-related dry eye (SSDE) and to explore their correlation with clinical features, dendritic cell activation, and serological indicators.

Methods: A total of 53 SSDE patients and 62 non-Sjögren's syndrome dry eye (NSSDE) patients were enrolled. Demographic and clinical data were collected, and comprehensive ophthalmic examinations were performed, including the ocular surface disease index (OSDI) questionnaires, Schirmer I test (SIT), tear break-up time (TBUT), corneal fluorescein staining score (CFS), and confocal microscopy (IVCM).
