Figure 25. Overview of the experimental setup and obtained results. Trophozoite staged IE of the P. falciparum IT isolate sequester to specific, transgenically expressed human endothelial receptors. The next generation RNA sequencing revealed differential upregulations of particular var genes for most of the enriched IT4 populations. The knob associated protein KAHRP was found at a highly increased expression level in IT4-CD37. The TEM analysis evidenced, that the initially knobless IT4-ST population exhibited knob structures, directly after sequestration for IT4-CD37 and IT4-CD81. Additionally, a knob
