Human rhinovirus 16 induces antiviral and inflammatory response in the human vascular endothelium.

The effect of rhinovirus on airway epithelium is very well described. However, its influence on the vascular endothelium is unknown. The current study assesses the effect of rhinovirus HRV16 on the antiviral and inflammatory response in the human vascular endothelial cells (ECs). HRV16 increased IFN-β, RANTES, and IP-10 mRNA expression and protein release. HRV16 copy number in ECs reached maximal value 10 h after incubation. Increase in virus copies was accompanied by the enhancement of Toll- and RIG-I-like receptors: TLR3, RIG-I, and MDA5. Additionally, HRV16 increased OAS-1 and PKR mRNA expression, enzymes responsible for virus degradation and inhibition of replication. ICAM-1 blockade decreased HRV16 copy number in ECs and inhibited IFN-β, RANTES, IP-10, OAS1, PKR, TLR3, RIG-I, and MDA5 mRNA expression increase upon subsequent induction with HRV16. The vascular endothelium may be infected by human rhinovirus and generate antiviral and inflammatory innate response. Results of the study indicate the possible involvement of the vascular endothelium in the immunopathology of rhinoviral airway infections. © 2020 APMIS. Published by John Wiley & Sons Ltd.
