The expression levels of the transporters slc1a6 (EAAT4, excitatory amino acid transporter 4), shared by Glu, were significantly increased 1 h after infection (Figure 2A); however, the mRNA expression levels of slc1a2 and slc1a7 were significantly reduced difference and others showed no significant difference at 1 h post-infection (Figure 2A). Here, SLC1A2 is linked to infection.
