Abstract

During the early stages of HIV-1 replication the conical capsid composed of p24 CA protein dissociates from the rest of the cytoplasmic viral complex by a process called uncoating. Although proper uncoating is known to be required for HIV-1 infection, many questions remain about the timing and factors involved in the process. Here we have used two complementary assays to study the process of uncoating in HIV-1–infected cells, specifically looking at the timing of uncoating and its relationship to reverse transcription. We developed a fluorescent microscopy-based uncoating assay that detects the association of p24 CA with HIV-1 viral complexes in cells. We also used an owl monkey kidney (OMK) cell assay that is based on timed TRIM-CypA–mediated restriction of HIV-1 replication. Results from both assays indicate that uncoating is initiated within 1 h of viral fusion. In addition, treatment with the reverse transcriptase inhibitor nevirapine delayed uncoating in both assays. Analysis of reverse transcription products in OMK cells revealed that the generation of early reverse transcription products coincides with the timing of uncoating in these assays. Collectively, these results suggest that some aspect of reverse transcription has the ability to influence the kinetics of uncoating.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
