Our data indicate that the failure of Dd2 to express the sialic acid-independent invasion receptor gene RH4 is associated with the epigenetic silencing mark H3K9 trimethylation present throughout the cycle.

This case strongly supports the hypothesis that parasite surface proteins such as PfEMP1, A-type RIFIN or STEVOR are involved in interactions of infected erythrocytes with endothelial receptors mediating sequestration of mature asexual and immature sexual stages of P. falciparum. In contrast, multicopy gene families coding for B-type RIFIN and PfMC-2TM proteins may not be involved in sequestration, as these genes were transcribed in infected but not sequestered erythrocytes.
