TNF and infection: Interestingly and except for HPRT1, IFNB1, IL1B, and TNF, the proportion of nuclear mRNAs is higher during the infection with MRU25010-30 compared to the infection with Mayotte 2008 (ANOVA two-way on ΔCt ratio, p < .01), corroborating strain-dependent variability of previous results on inhibition of protein secretion.
