Scientists Unveil Mechanism Behind Resistance to Severe Malaria

...ion, rosetting and cytoadherence — all depend on a parasite protein called PfEMP-1. To evade the immune system, the malarial parasites produce proteins, including PfEMP-1, that remodel the red blood cell’s surface to their advantage. For example, when spikes of PfEMP-1 are distributed evenly over the surface...
