Cryo-electron tomography (cryoET) allows 3D visualization of cellular structures at molecular resolution in a close-to-native state, and therefore has the potential to help elucidate early events of HIV-1 infection in host cells. However, direct observation of structural details of infecting HIV-1 has not been realized due to technological challenges in working with rare and dynamic HIV-1 particles in human cells. Here, we report structural analysis of HIV-1 and host-cell interactions by developing a correlative high-speed 3D live-cell imaging and cryoET method. Using this methodology, we showed, for the first time under near-native conditions, that intact hyperstable mutant HIV-1 cores are released into the cytoplasm of host-cells. We further obtained direct evidence to suggest that a hyperstable mutant capsid, E45A, delayed capsid disassembly compared to the wild-type capsid. Together, these results demonstrate the advantage of our correlative live-cell and cryoET approach to image dynamic processes, such as viral infection.
