Malaria infection caused by the Plasmodium species is a complex disease in which a fine balance between host and parasite factors determine the outcome of the disease. While in some individuals, the infection will trigger only a mild and uncomplicated disease, other individuals will develop severe complications and eventually die. Extracellular vesicles (EVs) secreted by infected red blood...

Malaria is a life-threatening disease caused by Plasmodium parasites, with P. falciparum being the most prevalent on the African continent and responsible for most malaria-related deaths globally. Several factors including parasite sequestration in tissues, vascular dysfunction, and inflammatory responses influence the evolution of the disease in malaria-infected people. P. falciparum-infected...

Malaria infected red blood cells release small regulatory RNAs through extracellular vesicles

The parasite Plasmodium falciparum causes the most severe form of malaria. Cell communication between parasites is an important mechanism to control population density and differentiation. The infected red blood cells (iRBCs) release small extracellular vesicles (EVs) that transfer cargoes between cells. The EVs synchronize the differentiation of the asexual parasites into gametocytes to initiate...
