Parasitology: Switching like for like
Piet Borst1 & Paul-André Genest1
Abstract
To remain hidden from its host's immune system, the malaria parasite must vary the proteins on the surface of the infected cell. The genes encoding these proteins are very similar, so how does the parasite express just one at a time?
Selecting one gene for activation out of many closely similar ones is tricky. Mammals address this problem when they switch on just one odorant receptor gene in each olfactory neuron, choosing between a thousand receptor genes.
