Unexpectedly, LCMV Clone 13 infection was not controlled in Il-10fl/flxCD11c-Cre+ mice (Figure 5A–D) and resulted in low percentages and total numbers of TNF-α producing antiviral CD8+ and CD4+ T cells comparable to littermate and C57BL/6 controls (Figure 5E–H). This evidence concerns the gene TNF and infection.
