ABSTRACT Enterovirus D68 (EV-D68) has emerged as a significant threat to public health because of its association with respiratory illnesses and neurological complications, including acute flaccid myelitis. However, the molecular mechanisms underlying EV-D68 replication pathogenesis remain unclear. Here, we revealed novel interaction between host Cullin-RING E3 ligase system, specifically Cullin 3, which was reported restrict viral replication. We initially demonstrated that proteasome inhibition enhanced replication, suggesting an important role for ubiquitin–proteasome system in restriction. 3 further identified key factor inhibits downregulation expression increased titers.

Virus-induced cell death is a key contributor to COVID-19 pathology. Cell induced by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) well studied in myeloid cells but less its primary host type, angiotensin-converting enzyme (ACE2)–expressing human airway epithelia (HAE). SARS-CoV-2 induces apoptosis, necroptosis, and pyroptosis HAE organotypic cultures. Single-cell limiting-dilution analysis revealed that necroptosis the event infected cells, whereas uninfected bystanders undergo occurs later during infection. Mechanistically, viral Z-RNA binding Z-DNA–binding protein 1 (ZBP1) lung tissues from patients with COVID-19. The Delta (B.1.617.2) variant, which causes more disease than Omicron (B1.1.529) humans, associated orders of magnitude–greater Z-RNA/ZBP1 interactions, severity animal models. Thus, robust ZBP1-mediated severity.
