Dose‐dependent pathogenicity and inflammatory imbalance in severely immunodeficient mice infected with mpox virus

Animal Models and Experimental Medicine, EarlyView.
This study establishes an NPG (NOD.Cg‐Prkdcscid Il2rgtm1/Vst) mouse model for severe monkeypox virus infection in immunocompromised hosts, demonstrating dose‐dependent disease severity and revealing that unbalanced pro‐inflammatory cytokine release drives pathogenesis, providing insights for therapeutic interventions. Abstract The global spread of mpox
