“…Owing to incomplete evidence, RHAG3 is provisionally assigned to the RHAG system. DSLK was initially named DL [8], but changed to DSLK (from letters in 'Duclos-like') to comply with the rule that symbols for designating new specificities will consist of three to six on-line, capital letters [1].…”

Complement receptor one (CR1) is a ligand for the rosetting of Plasmodium falciparum infected red cells with uninfected cells. Since CR1 exhibits three known polymorphisms, we studied European-Americans (n = 112) and African-Americans (n = 330) and Malians (n = 158) to determine if genetic differences existed in an area endemic for malaria that could offer a survival advantage. The frequencies of Knops blood group phenotypes McC(b+) and Sl(a−) were greatly increased in Africans vs Europeans. Although the frequency of McC(b+) was similar between Africans from the USA or Mali, the Sl(a−) phenotype was significantly higher in Mali (39% vs 65%, respectively). There was an increased frequency of the largest size (250 kD) of CR1 in Mali, but this did not differ significantly from the USA (P = 0.09). Both cohorts of Africans had higher expression of red cell CR1 than European-Americans but this showed little difference between the USA and Mali groups. Thus, the most important CR1 polymorphism relevant to rosetting of malaria infected cells appears to be the Knops blood group. Genes and Immunity (2000) 1, 325-329.

“…27 However, after detergent treatment of ghosts, which is required for the pull-down assays, a previously unrecognized 18-kDa species of GPA was observed ( Figure 2D, lane with NP-40 treatment). 27,28 It is known that solubilization of ghosts in nonionic detergents releases and activates several proteases that may give rise to smaller species of GPA. 29 The pull-down assays demonstrated that MSP1 12 associates with several species of GPA, including the homodimer, heterodimer, monomer, as well as an ;18-kDa band ( Figure 2D).…”

Merozoite surface protein 1 recognition of host glycophorin A mediates malaria parasite invasion of red blood cells

• The N-terminal subunit of MSP1 binds to a specific polypeptide region of GPA during merozoite invasion of human RBCs.• The GPA-band 3 complex plays an essential role during malaria parasite invasion.Plasmodium falciparum invasion of human red blood cells (RBCs) is an intricate process requiring a number of distinct ligand-receptor interactions at the merozoite-erythrocyte interface. Merozoite surface protein 1 (MSP1), a highly abundant ligand coating the merozoite surface in all species of malaria parasites, is essential for RBC invasion and considered a leading candidate for inclusion in a multiple-subunit vaccine against malaria. Our previous studies identified an interaction between the carboxyl-terminus of MSP1 and RBC band 3. Here, by employing phage display technology, we report a novel interaction between the amino-terminus of MSP1 and RBC glycophorin A (GPA). Mapping of the binding domains established a direct interaction between malaria MSP1 and human GPA within a region of MSP1 known to potently inhibit P falciparum invasion of human RBCs. Furthermore, a genetically modified mouse model lacking the GPA-band 3 complex in RBCs is completely resistant to malaria infection in vivo. These findings suggest an essential role of the MSP1-GPA-band 3 complex during the initial adhesion phase of malaria parasite invasion of RBCs. (Blood. 2015;125(17):2704-2711 IntroductionMalaria remains one of the most common and deadly parasitic diseases in the world. The World Health Organization estimates that 5% to 9% of the global population is infected by malaria annually, resulting in over 700 000 deaths.1 Children younger than 5 years are most vulnerable to Plasmodium falciparum, the most lethal species among 4 malaria parasites that commonly infect humans. Malaria also takes an enormous economic toll by impacting the economies of most endemic countries, particularly in sub-Saharan Africa. Historically, vaccines have been one of the most effective means of controlling infectious diseases. Accumulating evidence suggests that a malaria vaccine can be developed 2,3 ; however, most malaria vaccine candidate antigens have suffered limitations of low immunogenicity and efficacy. To date, no licensed vaccine exists for malaria despite the urgent global need.Clinical manifestation and mortality in malaria is directly associated with the blood stage of the parasite life cycle. The invasion process consists of multiple molecular events during which red blood cell (RBC) membrane proteins and merozoite-coat proteins are engaged in specific receptor-ligand interactions to form unique invasion pathways. 4,5 Continued interest in developing a multiantigen malaria vaccine has drawn much attention to parasite proteins localized on the surface and at the apical end of the merozoite as potential vaccine candidates. 4 Merozoite surface protein 1 (MSP1) is a major ligand coating the surface of merozoites in all species of malaria parasites 6 and is considered one of the leading candidates for inclusion in a multiplesubunit vaccine against...
