Innate immunity serves as the primary defense against viral and microbial infections in humans. Among its components, retinoic acid-inducible gene I (RIG-I)-like receptors (RLRs) are well-characterized intracellular pattern-recognition proteins that trigger innate immune responses upon viral infecti...
This modification plays a critical role in regulating protein function and cellular processes.MAVS succination sites were identified using mass spectrometry (MS). Identify succination sites of human MAVS protein.
Myeloid dendritic cells from WT, Irf3-/-xIrf7-/-, Irf3-/-xIrf5-/-xIrf7-/-, Mavs-/- (IPS1-/-)and Ifnar-/- mice were infected with West Nile virus to assess the contributions of specific signaling and transcription factors in initiating the antiviral response RPMI + rmGM-CSF purified bone marrow deriv...
Analysis of the transcriptional response of mouse embryonic fibroblasts to reovirus infection. The hypothesis tested was that both peroxisomal and mitochondrial MAVS is capable of inducing the expression of antiviral genes. mRNA isolated from MAVS-expressing cells after infection for various times ...
To identify the key molecules involved in ALOX15-mediated K63-linked ubiquitination of MAVS, we performed LC-MS/MS-based proteomics analysis of MAVS-interacting proteins in H1N1-infected A549 cells transfected with Flag-ALOX15 or plasmid vector. This analysis identified USP19, a deubiquitinase, as a...
Epstein-Barr virus (EBV) causes infectious mononucleosis, triggers multiple sclerosis and is associated with 200,000 cancers/year. EBV colonizes the B-cell compartment and periodically reactivates, inducing expression of 80 viral proteins. Yet much remains unknown about how EBV remodels host cells a...
The purpose of this study was to examine the role of MAVS and ZBP1 in the phenotype that develops when ADAR1 activity is missing, in particular when the Za domain of ADAR1 is mutated. Mice homozygous for a Za domain-mutant allele of Adar1 (Adar1mZa/mZa mice) were compared with control mice carrying ...
