Pyr01, a TACK NNRTI, markedly reduces incorporation of the HIV-1 Env glycoprotein into virions, linked to disrupted virion membrane order and lower infectivity.
- Why it matters: NNRTIs can trigger premature HIV-1 protease activation, but how this alters virion composition and infectivity during assembly is unclear.
- What they did: Using Pyr01 in virus-producing cells, the study tested Env and foreign viral glycoprotein incorporation, viral enzyme retention, membrane order, and protease dependence.
- The result: Pyr01 disrupts glycoprotein and enzyme incorporation, and the glycoprotein defect requires an active protease, implying protease-mediated disruption of the Gag lattice that changes membrane properties.
