3D imaging of undissected optically cleared Anopheles stephensi mosquitoes and midguts infected with Plasmodium parasites

Niz, Mariana De ; Kehrer, Jessica ; Brancucci, Nicolas M. B. ; Moalli, Federica ; Reynaud, Emmanuel G. ; Stein, Jens V. ; Frischknecht, Friedrich

In: PLOS ONE, 2020, vol. 15, no. 9, p. e0238134

Malaria is a life-threatening disease, caused by Apicomplexan parasites of the Plasmodium genus. The Anopheles mosquito is necessary for the sexual replication of these parasites and for their transmission to vertebrate hosts, including humans. Imaging of the parasite within the insect vector has been attempted using multiple microscopy methods, most of which are hampered by the presence of...

Optimizing long-lasting insecticidal nets campaign in Ivory Coast

Brito Junior, Irineu de ; Uneddu, Silvia ; Maspero, Emma ; Gonçalves, Paulo

In: Logistics, 2020, vol. 4, no. 3, p. 21 p

This research supports the United Nations Children’s Fund’s (UNICEF) conceptualization, planning and implementation of a campaign for distribution of more than 12 million mosquito nets in Ivory Coast. Procured from four different suppliers in Asia, the nets were transported to the two ports in Ivory Coast before being pre-positioned at 71 Health Districts across the country, a mixed integer...

Role of extracellular vesicles in cellular cross talk in malaria

Babatunde, Kehinde Adebayo ; Subramanian, Bibin Yesodha ; Ahouidi, Ambroise Dioum ; Murillo, Paola Martinez ; Walch, Michael

In: Frontiers in Immunology, 2020, vol. 11, p. -

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...

Evaluation of extracellular vesicle function during malaria infection

Andrea Hernández-Castañeda, María ; Mbagwu, Smart Ikechukwu ; Babatunde, Kehinde Adebayo ; Walch, Michael ; Filgueira, Luis ; Mantel, Pierre-Yves

In: JoVE (Journal of Visualized Experiments), 2018, no. 132, p. e57067

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...
