As expected, HHV-6A infection significantly increased the mRNA levels of Glut1 and Glut3 in HSB-2 cells at 24 h post-infection, and the expression level progressively increased at 48 h and 72 h post infection (more than a 10-fold increase at 72 h post infection compared with mock-infected cells) (Fig 2B). This evidence concerns the gene SLC2A3 and infection.
