At various time-points after infection (days 4, 7, 9, 12, 15, 18, 21 and 30), we determined the virus titers in spleen (Figure 1A) and liver (Figure 1B) via Focus-Forming Assay, as well as by quantitative RT-PCR of liver RNA for the LCMV Z protein (Figure 1C). The gene discussed is TMBIM4; the disease is infection.
