Project description:
Cryptosporidium spp. are intestinal parasites which cause severe diarrhoea in humans, especially in HIV patients and young children. Especially in developing countries these protozoan infections induce high morbiditiy and mortality. So far, epidemiological factors contributing to cryptosporidiosis in underdeveloped countries – such as Cameroon – have insufficiently been studied. Currently available therapeutics show insufficient efficacies in the above mentioned risk groups. Cryptosporidium spp. are obligate intracellular protozoa which own minimal metabolic capacities. Consequently, to sustain their intracellular proliferation, these parasites have to modulate the host cellular metabolism. By characterizing metabolic signatures of C. parvum-infected host cells, we recently identified host cell metabolic reactions and pathways that are essential for parasite proliferation.
Scientific goal:
This projects targets specific metabolic pathways of host cells (mainly glycolysis and glutaminolysis) by using new metabolic inhibitors or combinatory treatments. Moreover, a One Health study on several epidemiological factors of cryptosporidiosis in Cameroon is conducted.
