Mechanism of Enhanced Immature Dengue Virus Attachment to Endosomal Membrane Induced by prM Antibody

？ ImmDENV3 complexed with anti-prM antibody structures at neutral and acidic pH ？ Two structural classes at acidic pH represent DENV maturation intermediates ？ Structures show how the antibody helps overcome barrier for immature virus to fuse ？ MD simulates maturation structural transitions and antibody assisted removal of p
