The present invention relates to
nucleic acid molecules related to the var2csa
gene family as well as
amino acid sequences encoded by such
nucleic acid molecules with respect to their role in mediating adhesion of infected red blood cells to
chondroitin sulphate A (CSA) in the
placenta which is characteristic for the
pathogenesis of
pregnancy associated
malaria (PAM). Accordingly, The invention provides the use compounds that are related to VAR2CSA polypeptides var2csa
nucleic acid molecules as medicaments, as well as it provides pharmaccutical compositions, in particular immunological compositions and vaccines, hereunder
nucleotide-based vaccines comprising these compounds. In addition, the invention provides the use of the compounds mentioned for the manufacture of compositions, such as immunogenic compositions. Other aspects of the invention relates to methods of treatment and prevention of
pregnancy associated
malaria wherein these methods are based on the nucleic acid molecules and polypeptides the invention. As these compounds can also be used as biotechnological tools the invention provides
in vitro diagnostic methods and kits comprising reagents and IgGs / antibodies designated to the use in such methods. The invention also relates to methods of identifying agents capable of modulating the VAR2CSA dependent adhesion to CSA and agent capable of interacting with VAR2CSA. Finally, a method for identifying polypeptides, which will induce a
specific IgG /
antibody response upon administration to a subject is provided by the invention.
