Cover Story: Resistance has emerged against anti-HIV agents such as integrase strand transfer inhibitors (INSTIs) and third-generation non-nucleoside reverse transcriptase inhibitors (NNRTIs) that have been effective against HIV variants resistant to previous-generation AIDS treatments. The emergence of drug resistance is attributable in part to regimen non-adherence. Dual and triple therapies that combine certain NNRTIs and INSTIs are being developed that are comparable in efficacy to previous triple therapies. Some of these experimental treatments are being developed as long-acting therapies to be administered weekly, monthly, or less frequently. These new combination therapies may be safer than previous treatments and may promote better regimen adherence as long-term maintenance treatments. View this paper

Multi-Step Ubiquitin Decoding Mechanism for Proteasomal Degradation

  • Hikaru Tsuchiya,
  • Akinori Endo and
  • Yasushi Saeki

The 26S proteasome is a 2.5-MDa protease complex responsible for the selective and ATP-dependent degradation of ubiquitylated proteins in eukaryotic cells. Proteasome-mediated protein degradation accounts for ~70% of all cellular proteolysis under ba...
