Given that these protein level data are consistent with our microarray and qRT-PCR observations that FCRL5, but not FCRL4, is more highly expressed by malaria-associated atMBCs than classical MBCs, it is likely that FCRL5 is the actual target recognized on these cells by previous malaria studies that used clone 2A6 [11,31]. Here, FCRL5 is linked to malaria.
