Fibrinogen Binding to Intercellular Adhesion Molecule 1: Implications for Plasmodium falciparum Adhesion

Intercellular adhesion molecule 1 (ICAM-1) is an endothelial cell adhesion molecule implicated in cerebral malaria. We investigated whether fibrinogen affects Plasmodium falciparum binding to ICAM-1, as the ICAM-1 binding sites of P. falciparum and fibrinogen overlap. We show that fibrinogen dramatically reduces P. falciparum adhesion to ICAM-1 under flow conditions.
