Or adhesion is thought to be the chondroitin sulphate A (CSA) component of the chondroitin sulphate proteoglycan (CSPG) [46?0]. Placentalparasite variants that adhere to CSA show an absence of binding to CD36 and ICAM-1 ligands, in contrast to parasite variants taken from infected non-pregnant women [51?53]. Selection of pRBC that adhere to CSA in vitro leads to the loss of antigens that bind to C
