Linear ubiquitination mediates coronavirus NSP14-induced NF-κB activation.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Human coronaviruses exhibit a spectrum of symptoms, ranging from mild seasonal colds to severe respiratory manifestations. Despite progress in understanding the host's innate defense mechanisms against coronaviruses, how these viruses manipulate the immune response to promote inflammation remains elusive. In this study, we unveil the role of the coronavirus nonstructural protein 14 (NSP14) in leveraging the host's linear ubiquitin chain assembly complex (LUBAC) to instigate NF-κB activation, thereby triggering proinflammatory responses. Our findings uncover that HOIL-1-interacting protein (HOIP) directly engages with NSP14, conferring linear polyubiquitin chains onto NSP14. Consequently, ubiquitinated NSP14 recruits NEMO and initiates the activation of the IKK complex. This NSP14-induced NF-κB activation stimulates the expression of proinflammatory factors but not type I interferon, leading to a skewed host innate immune response tilting to inflammation. Collectively, our study sheds light on a virus-initiated linear ubiquitination pathway that induces NF-κB signaling and provokes proinflammatory responses.
