Mpox virus replicates in lung organoids without significantly affecting their cellular function.

ABSTRACT: Patients with mpox may present with a skin rash and mild respiratory symptoms, including sore throat and cough. The genome of the mpox virus (MPXV) has been detected in throat swab specimens from some mpox patients, indicating potential involvement of the respiratory tract. In this study, we used lung organoids to investigate the effects of MPXV infection on the respiratory system by evaluating the viral replication and the infection-mediated host response. MPXV infection resulted in the accumulation of high levels of viral genomes within the cells. H&E staining showed almost no histological differences between MPXV-infected lung organoids and uninfected lung organoids. In addition, RNA-seq analysis revealed that MPXV infection did not significantly alter the gene expression levels of vari
