Abstract
It was recently shown that vertebrates, ranging from fish to primitive mammals, possess type IV IFN (IFNυ). However, their precise function and elaborate signaling remains unknown. In this study, CaIFNυ was identified from Carassius gibelio and its transcriptional regulation and signaling was further investigated. Firstly, CaIFNυ displays significant differences in the distribution, magnitude, and kinetics of its antiviral properties compared with CaIFNa1, a typical type I IFN from C. gibelio. Secondly, IRF1/3/7 differentially activated CaIFNυ through homo- or heteroprotein complexes in a dose-dependent fashion and NF-κB (p65) was the most effective stimulator. Thirdly, CaIFNυ initiates the antiviral ISGs through the JAK-STAT as well as MAPK and PI3K signaling pathways by binding to the extra-cellular region of CaCRFB4 and CaCRFB12. Taken together, these findings reveal that CaIFNυ belonges to an antiviral cytokine lineage which is distinct from CaIFNa1.
期刊介绍:
Cell Communication and Signaling (CCS) is a peer-reviewed, open-access scientific journal that focuses on cellular signaling pathways in both normal and pathological conditions. It publishes original research, reviews, and commentaries, welcoming studies that utilize molecular, morphological, biochemical, structural, and cell biology approaches. CCS also encourages interdisciplinary work and innovative models, including in silico, in vitro, and in vivo approaches, to facilitate investigations of cell signaling pathways, networks, and behavior.
Starting from January 2019, CCS is proud to announce its affiliation with the International Cell Death Society. The journal now encourages submissions covering all aspects of cell death, including apoptotic and non-apoptotic mechanisms, cell death in model systems, autophagy, clearance of dying cells, and the immunological and pathological consequences of dying cells in the tissue microenvironment.
