Liposomes loaded with P. falciparum merozoite-derived proteins are highly immunogenic and produce invasion-inhibiting and anti-toxin antibodies.

The formulation of an effective vaccine against malaria is still a significant challenge and the induction of high anti-parasite antibody titers plus a sustained T cell response is mandatory for the success of such a vaccine. We have developed a nanoliposome-based structure which contains plasma membrane-associated proteins (PfMNP) of Plasmodium falciparum merozoites on its surface. Incorporation of parasite-derived proteins led to a significant increase in the size and dispersity of particles.
