Building a Better Mosquito: Identifying the Genes Enabling Malaria and Dengue Fever Resistance in A. gambiae and A. aegypti Mosquitoes

In this interview, George Dimopoulos focuses on the physiological mechanisms used by mosquitoes to combat Plasmodium falciparum and dengue virus infections. Explanation is given for how key refractory genes, those genes conferring resistance to vector pathogens, are identified in the mosquito and how this knowledge can be used to generate transgenic mosquitoes that are unable to carry the malaria parasite or dengue...

Preventing the Spread of Malaria and Dengue Fever Using Genetically Modified Mosquitoes

In this candid interview, Anthony A. James explains how mosquito genetics can be exploited to control malaria and dengue transmission. Population replacement strategy, the idea that transgenic mosquitoes can be released into the wild to control disease transmission, is introduced as well as the concept of genetic drive and the design criterion for an effective genetic drive system. The ethical considerations of releasing genetically-modified organisms into the wild are also...

Injection of An. stephensi Embryos to Generate Malaria-resistant Mosquitoes

Anopheles stephensi mosquitoes are vectors for malaria inhabiting India and throughout Asia. This video demonstrates the technique for performing microinjections of this species with transgenes that will confer resistance to the malaria to the mosquito. Much of the methodology demonstrated in this video is applicable to microinjection techniques of other mosquito...

Understanding the Development of Compensatory Pathways in a Mutant Malaria Parasite Harbouring Hypomorphic Allele of Plant-Like Kinases09:13

Understanding the Development of Compensatory Pathways in a Mutant Malaria Parasite Harbouring Hypomorphic Allele of Plant-Like Kinases

Chemical genetics involves the substitution of a gatekeeper residue with an amino acid containing a different side chain at the target locus. Here, we have generated a mutant parasite containing a hypomorphic allele of cdpk1 and identified compensatory pathways adopted by the parasite in the mutant...

Protocol for Production of a Genetic Cross of the Rodent Malaria Parasites

Genetic crosses of rodent malaria parasites are performed by feeding two genetically distinct parasites to mosquitoes. Recombinant progeny are cloned from mouse blood after allowing mosquitoes to bite infected mice. This video shows how to produce genetic crosses of Plasmodium yoelii and is applicable to other rodent malaria...

Generation of a Mouse Model of Experimental Cerebral Malaria Using Host Mosquito-Derived Sporozoites03:28

Generation of a Mouse Model of Experimental Cerebral Malaria Using Host Mosquito-Derived Sporozoites

This video demonstrates the generation of an experimental mouse model of cerebral malaria. Sporozoites isolated from Plasmodium berghei-infected female mosquitoes are injected into a restrained mouse's tail veins, leading to blood-brain barrier disruption and brain inflammation, causing cerebral malaria. This infected mouse model offers a valuable tool to study in vivo microvascular pathology associated with cerebral...
