New malaria control interventions though targeting the mosquito blood meal; determining the endectocidal and gametocytocidal effects of novel chemotherapeutics.

A number of drugs administered to humans to control malaria and other infectious diseases have been observed to have an additional benefits by reducing onward malaria transmission. For example the drug ivermectin, a broad-spectrum antiparasitic compound used for the treatment and control of onchocerciasis and lymphatic filariasis has also be observed to kill malaria mosquitoes who feed on treated individuals (endectocidal). 

Similarly the anti-malarial drug primaquine kills Plasmodium falciparum gametocytes, the sexual stage of the parasite found in the mosquito vector, thereby preventing transmission (gametocytocidal). The aim of this project is to determine the endectocidal and gametocytocidal impacts of a range of chemotherapeutics administered individually and in combinations. The candidate will be based between the departments of Vector Biology and Tropical Disease Biology and will conduct a range of experiments including experimental mosquito infections both in the UK and sub Saharan Africa.  The study will involve a number of technologies, including; molecular genetic screening, high-content imaging, confocal laser scanning microscopy, flow cytometry/cell sorting and potentially analytical techniques e.g. LC-MS/MS.

Where does the project lie on the Translational Pathway?

T1 (Basic Research) + T2 (Human/Clinical Research) + T3 (Evidence into Practice)

Expected Outputs

The project will produce high quality REF returnable 3*/4* publications and will provide the evidence base for large scale research council and industry funding. Recent PhD graduates from our labs have published extensively in the general science journals (Nature, PNAS, Nature Communications). This is a key strategic area for LSTM and brings together research groups from across the Biological Sciences faculty

Training Opportunities

The student will gain skills in rigorous, replicated experimental design; statistical analysis; mosquito rearing; experimental infections; parasitology;  molecular genetic screening, high-content imaging, confocal laser scanning microscopy, flow cytometry/cell sorting and potentially analytical techniques e.g. LC-MS/MS. Microscopy.  Quantitative skills involve statistical analyses and potentially some PK-PD modelling.
