SLC38A3 and infection: As illustrated in Figure 6, at twelve and twenty-four hours after infection, the RNA of PRRSV and the TCID50 of PRRSV in supernatants of PRRSV + ICs-infected PAMs pre-blocked by anti-Sn1, 2, 3, 4, 5, 6, or 1–9 IgG were observably lower than those in supernatants of PRRSV + ICs-infected PAMs pre-blocked by RNI, whereas the RNA of PRRSV and the TCID50 of PRRSV in supernatants of PRRSV + ICs-infected PAMs pre-blocked by anti-Sn7, 8, or 9 IgG were no significant differences compared to those in supernatants of PRRSV + ICs-infected PAMs pre-blocked by RNI.
