Mapping a common interaction site used by Plasmodium falciparum Duffy binding-like domains to bind diverse host receptors.

The Duffy binding-like (DBL) domain is a key adhesive module in Plasmodium falciparum, present in both erythrocyte invasion ligands (EBLs) and the large and diverse P. falciparum erythrocyte membrane protein 1 (PfEMP1) family of cytoadherence receptors. DBL domains bind a variety of different host receptors, including intercellular adhesion molecule 1 (ICAM-1), a receptor interaction that may have a role in infected erythrocyte binding to cerebral blood vessels and cerebral malaria.

Global genetic diversity and evolution of var genes associated with placental and severe childhood malaria.

In Plasmodium falciparum, var genes encode adhesive proteins that are transported to the surface of infected erythrocytes and act as major virulence determinants for infected erythrocyte binding and immune evasion. Var genes are highly diverse and can be classified into five major groups (UpsA, B, C, D, and E). Previous serological studies have suggested that the UpsA var group may contain common antigenic types that have important roles in severe childhood malaria.
