Hypothesis
Can histone deacetylase inhibitors effectively reactivate latent HIV in primary CD4 T cells?
Conclusion
The study found that HDAC inhibitors valproic acid and trichostatin A do not reactivate latent HIV in primary CD4 T cells.
Supporting Evidence
- VPA and TSA did not increase the percentage of HIV-p24+ cells in treated cultures compared to untreated controls.
- Prostratin treatment led to a significant increase in HIV-p24+ cells, unlike VPA or TSA.
- The study demonstrated that latent HIVs in primary quiescent CD4 T-lymphocytes are not responsive to HDAC inhibitors.
Takeaway
The drugs tested didn't help wake up the sleeping HIV in the immune cells, which is important for finding a cure.
Methodology
The study involved generating latently HIV-infected primary T cells and treating them with HDAC inhibitors to assess HIV reactivation.
Limitations
The study's findings may not apply to all types of T cells or other conditions affecting HIV latency.
Participant Demographics
Normal donors' blood was used to obtain CD4 T cells.
