As the expression levels of IFN-receptors play an important role for the production of IFNs in a positive feedback loop we determined the mRNA receptor levels of type III interferon-lambda receptor 1 (IFNLR1) and type I interferon-α/β receptor 1 (IFNAR1) before infection with RV as well as at 8 and 24 hpi. The gene discussed is IFNAR1; the disease is infection.
