Cyro-et of env on intact
WebCorrelated cryo-fluorescence light microscopy (cryoFLM) and cryoET of frozen, hydrated cells can be used to study cellular and molecular functions and dynamics in the 3D context of cells and tissues at a higher resolution than any other imaging technique. WebLooking at native HIV virions using cryo-ET shows how Env interacts with Gag and reveals variability in Env conformations that is relevant for understanding interactions with antibodies.

WebMar 2, 2024 · Using extensive all-atom molecular dynamics simulations of HIV-1 cores imaged from cryo-electron tomography (cryo-ET) in intact virions, which contain IP 6 and a ribonucleoprotein complex, we find markedly striated patterns of strain on capsid lattices. The presence of these cofactors also increases rigidity of the capsid.
WebNov 26, 2024 · Imaging cells by cryo-ET requires samples that are thin enough to allow electrons with energies of 300 keV to be transmitted — typically not much more than 300 nm. Most cells exceed these dimensions and are too thick to study intact in cryo-transmission electron microscopy (cryo-TEM), and must consequently be thinned before …
