Induction of viral sensors and antiviral genes such as MDA5, MX1, OAS1 has also been observed in human MCs infected with dengue virus 35 and vaccinia virus 54, but reports of up‐regulation of these genes following infection with respiratory viruses are limited to sendai virus infection, a murine virus used to model human parainfluenza virus infection 37. The gene discussed is MX1; the disease is infection.
