TYK2 belongs to the Janus/JAK family of protein tyrosine kinases and is involved in signaling of immunoregulatory cytokines (type I and type III IFNs, IL-6, IL-10 and IL-12 families) that contribute to a balanced […]

We have investigated whether IFN-I activates the mTOR translational control pathway and to what extent the control of mRNA translation contributes to IFN α2/β responses. General questions have been addressed by a genome-wide search […]

We recently uncovered a potentially interesting connection between ISGylation and cell cycle regulation. We reported that the degradation of USP18, major negative regulator of IFN-I signaling, involves SKP2, a well known actor in cell […]

We have reported on the implication of the ubiquitin-like ISG15 protein in the negative regulation of IFN-I response in humans. ISGylation is a major post-translational modification whereby numerous proteins are conjugated to ISG15, with […]

The type I IFN system needs to be regulated not only at the level of its production, but also at the level of responses. We have shown that cells that have responded to IFN-I […]
