Structural Immunology - Graham BENTLEY (Unit Closed)

Activities of the Unit

Research themes of the unit centre on the structural and functional characterization of macromolecules with a biomedical interest, with particular emphasis given to antigens from infectious agents that are vaccine candidates or targets for drug design (malaria, shigellosis). Structural studies by X-ray crystallography form the mainstay of our research.
(1) Plasmodium vaccine candidates: PfEMP1, AMA1 (G. Bentley)
(2) Antigenic recognition of LPS from Shigella flexneri (B. Vulliez-Le Normand)
(3) Site-specific recombinases from Plasmodium falciparum and Vibrio cholerae (D. Gopaul)
(4) Neurotoxic and anticoagulant phospholipases A2 from serpents (G. Faure)
