Inhibition of erythrocyte binding by DBL domains with MGSA. (A–D) Erythrocyte-binding assays were performed by using radio-labeled culture supernatants containing P. vivax region II (V), P. knowlesi β region II (Kβ), and CH4 with Duffy-positive (POS) human erythrocytes (RBCs) or rhesus RBCs in the presence of the chemokine MGSA. Binding at each MGSA concentration is expressed as a percentage of binding in the absence of MGSA.
