A research report submitted to the faculty of Medicine, University of the Witwatersrand, Johannesburg, in part fulfillment of the requirements for the degree of Master of Medicine (in the branch of Haematology) Johannesburg 1992. / The observation by Haldane in 1949 that the distribution of malaria and certain thalassaemias were similar and that the former disease must be a selective force tor the continued existence of the latter by preservation of the heterozygotes. This theory which later became known as lithe malaria hypothesis" has been applied to other inherited conditions such as G6PD deficiency, membranopathies, certain blood group polymorphisms, other heamoglobinopathies such as sickle cell disease, blood group polymorphisms and more recently HLA phenotypes. It has been shown that the Duffy blood group antigens are the receptors for. Plasmodium vivax and since these antigens are lacking in most black Africans this species of malaria is virtually absent in Africa. It has also been shown that the glycophorins are at least in part the receptors for Pfalciparum. Several variants of the glycophorins exist and the biochemistry and, where known, the molecular mechanisms by which these arise is reviewed. Experimental work is carried out to establish the growth characteristics of Pfalciparum in an in vitro culture system using cells with glycophorin variants on their membranes. Three such variants were compared to normal cells and two (S~s-U-and Dantu) were found to be partially resistant to invasion by Pfalciparum merozoites whereas the third (Henshaw) was found to be no different to controls. / MT2018
