Additionally, MDBK cells incubated with BRSV at 4°C for 1 h were transferred to 37°C for 30 min, the localization of dynamin-2 and BRSV G protein was analyzed by IFA and confocal microscopy, the result showed clear co-localization of dynamin-2 and G protein after 30 min of infection (Figure 2I). Here, DNM2 is linked to infection.
