Wetland virus exposes blind spots in orthonairovirus pathogenesis.

Wetland virus causes cell death and liver damage by triggering pyroptosis and lipid accumulation, revealing critical gaps in understanding orthonairovirus pathogenesis.

• Why it matters: Understanding how emerging orthonairoviruses cause disease is essential for developing effective treatments, as their pathogenic mechanisms are currently poorly understood.
• What they did: Wang et al. investigated the effects of Wetland virus on human cells, demonstrating its convergence on caspase-3-gasdermin E pyroptosis and fatty acid synthase-dependent hepatic lipid buildup.
• The result: This work links cell death pathways to metabolic injury, highlighting new targets for host-directed therapy and advancing knowledge of orthonairovirus-induced disease processes.
