At day 7 p.i., we observed the significant increase in the number of MCMV EA-positive cells in the retinas of Atg5flox/flox; Nestin-Cre mice compared to control mice after viral infection (Fig. 3d), though virus titer in Atg5flox/flox; Nestin-Cre mice was not statistically different from Atg5+/+; Nestin-Cre and Atg5flox/+; Nestin-Cre mice (Fig. 3e). This evidence concerns the gene ATG5 and viral infectious disease.
