Abstract

Enhanced expression of Pellino-1 (Peli1), a ubiquitin ligase is known to be associated with COVID-19 susceptibility. The underlying mechanisms are not known. Here, we report that mice deficient in Peli1 (Peli1^-/-) had reduced viral load and attenuated inflammatory immune responses and tissue damage in the lung following SARS-CoV-2 infection. Overexpressing Peli1 in 293 T cells increased SARS-CoV-2 infection via promoting virus replication and transcription, without affecting virus attachment and entry into the cells. Smaducin-6 treatment which is known to disrupt Peli1-mediated NF-KB activation, attenuated inflammatory immune responses in human lung epithelial cells as well as in the lung of K18-hACE2 mice following SARS-CoV-2 infection, though it had minimal effects on SARS-CoV-2 infection in human nasal epithelial cells. Overall, our findings suggest that Peli1 contributes to SARS-CoV-2 pathogenesis by promoting virus replication and positively regulating virus-induced inflammatory responses in lung epithelial cells. Peli1 is a therapeutic target to control SARS-CoV-2 -induced disease severity.

期刊介绍： Antiviral Research is a journal that focuses on various aspects of controlling viral infections in both humans and animals. It is a platform for publishing research reports, short communications, review articles, and commentaries. The journal covers a wide range of topics including antiviral drugs, antibodies, and host-response modifiers. These topics encompass their synthesis, in vitro and in vivo testing, as well as mechanisms of action. Additionally, the journal also publishes studies on the development of new or improved vaccines against viral infections in humans. It delves into assessing the safety of drugs and vaccines, tracking the evolution of drug or vaccine-resistant viruses, and developing effective countermeasures. Another area of interest includes the identification and validation of new drug targets. The journal further explores laboratory animal models of viral diseases, investigates the pathogenesis of viral diseases, and examines the mechanisms by which viruses avoid host immune responses.
