Atomic structure of the ectodomain from HIV-1 gp41
Fusion of viral and cellular membranes by the envelope glyco-protein gp120/gp41 effects entry of HIV-1 into the cell. The precursor, gp160, is cleaved post-translationally into gp120 and gp41 (refs 1,2), which...

Structure of the influenza virus haemagglutinin complexed with its receptor, sialic acid
The three-dimensional structures of influenza virus haemagglutinins complexed with cell receptor analogues show sialic acids bound to a pocket of conserved amino acids surrounded by antibody-binding sites. Sia...

Three-dimensional structure of an antigenic mutant of the influenza virus haemagglutinin
Antigenic variation in the haemagglutinin (HA) glycoprotein of influenza virus is associated with recurrent epidemics of respiratory disease in man (for review see ref. 1). We have examined the size of structu...

Single amino acid substitutions in influenza haemagglutinin change receptor binding specificity
The haemagglutinin (HA) glycoproteins of influenza virus membranes are responsible for binding viruses to cells by interacting with membrane receptor molecules which contain sialic acid (for review see ref. 1)...

Influenza A specific cytotoxic T-cell clones that do not recognize viral glycoproteins
Since the demonstration that murine cytotoxic T cells generated during a secondary immune response to influenza A viruses were composed of cross-reactive and subtype-specific populations1–5, it has become of inte...

Structural identification of the antibody-binding sites of Hong Kong influenza haemagglutinin and their involvement in antigenic variation
Four ‘antigenic sites’ on the three-dimensional structure of the influenza haemagglutinin are identified. At least one amino acid substitution in each site seems to be required for the production of new epidem...

Structure of the haemagglutinin membrane glycoprotein of influenza virus at 3 Å resolution
The haemagglutinin glycoprotein of influenza virus is a trimer comprising two structurally distinct regions: a triple-stranded coiled-coil of α-helices extends 76 Å from the membrane and a globular region of a...

Cytotoxic T cells kill influenza virus infected cells but do not distinguish between serologically distinct type A viruses
THE molecular basis of recognition and target cell killing by cytotoxic T cells is still unknown. Doherty and Zinkernagel showed that mouse cells infected with lymphocytic choriomeningitis virus can be lysed b...
