Abstract
In this study, we detected multiple var gene transcripts within single, mature trophozoite-infected red blood cells (iRBCs) bound to chondroitin sulphate A (CSA). Several of the var detected had previously been demonstrated to encode Plasmodium falciparum erythrocyte membrane protein-1 (PfEMP-1) variants with domains that mediated iRBC adhesion to receptors other than CSA. Parasites expressing the CSA-adherent phenotype transcribed far more of one var than of all others, but this gene was different from the two other var previously purported to encode adhesion to CSA. Previous work suggesting that only single var are transcribed by mature trophozoites needs re-examination in the light of these data from single, infected cells.
