Innate immune responses to Plasmodium falciparum infected erythrocytes
+61 3 8344 3259
The project takes place in Melbourne and in Blantyre, Malawi
Our aims are
1. To determine whether parasite binding phenotype helps drive the innate immune response to Plasmodium falciparum infected erythrocytes
2.To discover whether binding phenotype and gene expression of clinical isolates influences cytokine secretion in vivo and in vitro. We are collecting malaria parasites from Malawian children with severe or mild malaria, and will examine the immune responses they generate from white blood cells.
3. To compare the proportions of different monocyte subsets and their uptake of malaria infected cells, using samples from children with severe and mild malaria. Follow up studies after recovery are also done.
4. To understand the roles of intermediate monocytes in clearance of malaria and cytokine response, and its possible importance in
Our outcome of interest is an improved understanding of how host and parasite combinations increase risk of severe malaria.

CD14(hi)CD16+ monocytes phagocytose antibody-opsonised Plasmodium falciparum infected erythrocytes more efficiently than other monocyte subsets, and require CD16 and complement to do so.
