Hypothesis

How do different HIV-1 subtypes affect proviral latency and transcriptional activation?

Conclusion

Subtype AE shows increased basal transcription levels but a reduced response to TNFα activation compared to other subtypes.

Supporting Evidence

  • The majority of HIV-1 infected T cells only start viral gene expression after TNFα activation.
  • Subtype AE combines increased basal transcription with a reduced TNFα response.
  • TNFα treatment induced a significant 3-fold increase in CA-p24 positive cells.

Takeaway

HIV-1 can hide in the body and not show symptoms, but some types are better at hiding than others. This study looks at how different types of HIV-1 behave when trying to wake up from hiding.

Methodology

The study used a single round infection assay to measure HIV-1 transcriptional latency in T cell lines.

Limitations

The study primarily focused on subtype B and may not fully represent all HIV-1 subtypes.
