HIV Nanoparticle Vaccine
Self-assembling nanoparticle + Stabilized envelope trimer = Prophylactic HIV vaccine
This animation depicts how one of our leading HIV-1 vaccine candidates is designed. Dihydrolipoyl acetyltransferase (E2p) from Bacillus stearothermophilus is a protein that can automatically assemble into a 60-meric nanoparticle with a diameter of 23.2 nm. After an HIV-1 envelope glycoprotein (Env) has been stabilized by our “uncleaved, prefusion-optimized (UFO)” design, it can be displayed on the E2p surface through gene fusion. The outcome is a nanoparticle vaccine of 40-60 nm in size with 20 native-like viral spikes on the surface poised for immune recognition.
