3-D Rconstruction of Immature HIV Lattice (IMAGE) European Molecular Biology Laboratory Caption Lattice maps for immature HIV particles. The 3-D computer reconstruction shows the immature Gag lattice of HIV that matures to form the protein shell of the infectious virus. Maps are shown in perspective such that hexamers on the rear surface of the particle appear smaller. The side of the particle toward the viewer lacks ordered Gag.
