A major hurdle in curing HIV is the "latent reservoir"—cells where the virus hides and remains invisible to the immune system. Recent research published in PLOS Pathogens (article ID 8137) provides a deep dive into why these cells are so hard to wake up and kill.
Extensive changes in the cell's proteins (the proteome) and gene expressions (the transcriptome) effectively "quench" the signals that should trigger the virus to reactivate. 8137 epub
By identifying the specific proteins involved (like p53 and STAT3), scientists can develop pharmacological strategies to make these "inert" cells responsive again, potentially leading to more effective "shock and kill" therapies. A major hurdle in curing HIV is the
