PfNd9 is essential for rhoptry secretion in P. falciparum. Left: IFA images illustrating AMA1 protein stored in micronemes (top) or secreted and translocated at the surface of the parasite before egress (bottom). Middle: Magnified images of the areas indicated by a dashed box to the left. Right: quantification of the results. The means of two independent experiments are shown.
