BCL3 and infection: An increase of Bcl-xL-positive cells in RML6-infected C57Bl/6 mice compared with uninfected animals was found at 11 weeks after infection, while a reduced number of Bcl-xL-expressing cells was found in the brain of NF-κB2- and Bcl-3-deficient mice compared with C57Bl/6 mice at the same time point (Fig. 7A).
