MX1 and infection: We next sought to determine preadipocytes’ response to infection (MOI of 1, at 24 hpi) by quantifying the expression of the antiviral innate-immune-related genes Tlr3 (coding for Toll-like receptor 3), RigI (coding for retinoic acid-inducible protein I), Mda5 (coding for melanoma-differentiation associated protein 5), Mx1 (coding for Mx1), and Vip (coding for viperin) (Fig. 6c).
