Figure 4: HHV-6 exposure reduces the levels of OVA-specific IgE and IgG1 in serum. OVA-specific serum IgE (A) and IgG1 (B) titers are significantly diminished after exposure to HHV-6 (fi lled circles) as compared to control exposed mice (empty circles). Data represent the OVA-specific IgE PCA titer (A) and the OVA-specific IgG1 (log10) titer (B) for each individual (circles) and the median value for each group (line) from 4 (A) and 2 (B) independent experiments with at least 5 animals/group.
