Plasmodium falciparum-infected erythrocytes adhere dichotomously to the host receptors CD36 and chondroitin sulfate A (CSA). This dichotomy is associated with parasite sequestration to microvasculature beds (CD36) or placenta (CSA), leading to site-specific pathogenesis. Both properties are mediated by members of the variant P. falciparum erythrocyte membrane protein 1 (PfEMP-1) family and resi...
The Duffy blood group antigen has been characterized by its roles on red blood cells: as a receptor for the malarial parasites and as a promiscuous receptor for chemokine superfamily. Recently, the Duffy blood group associated glycoprotein D (gpFy) cDNA has been cloned (Chaudhuri et al: Proc Natl Acad Sci USA 90:10793, 1993). In this report we describe the organization of genomic DNA coding for...
Human serum albumin (HSA) is the most abundant protein in the blood plasma. Molecular dynamics simulations of subdomain IIA of HSA and its complex with salicylic acid (SAL) were performed to investigate structural changes induced by the ligand binding. To estimate the binding affinity of SAL molecule to subdomains IB and IIA in HSA protein, binding free energies were calculated using the Molecu...
abstractinteraction of ni complex(salen= n, n´-ethylene bis(salicylideneimine)) with hen egg-white lysozyme (hewl) was studied by absorption spectroscopy, competitive binding study and thermal denaturation study. the protein binding affinity of ni complex was found to be (3.0×103m−1). the binding plot obtained from the absorption titration data gives a binding constant of 2.4 (± 0.3)×103 m-1. i...
background: retinol?binding protein 4 (rbp4) is known to regulate lipid and glucose metabolism and insulin resistance. the influences of rbp4 on metabolic syndrome (ms) are still unclear. the purpose of this study is to evaluate the association between serum levels of rbp4 and ms components in first?degree relations of type 2 diabetic patients. materials and methods: this cross?sectional study ...
BACKGROUND Plasmodium vivax shows a small prevalence in West and Central Africa due to the high prevalence of Duffy negative people. However, Duffy negative individuals infected with P. vivax have been reported in areas of high prevalence of Duffy positive people who may serve as supply of P. vivax strains able to invade Duffy negative erythrocytes. We investigated the presence of P. vivax in t...
Pregnancy-associated malaria (PAM) is a serious consequence of sequestration of Plasmodium falciparum-parasitized erythrocytes (PE) in the placenta through adhesion to chondroitin sulfate A (CSA) present on placental proteoglycans. Recent work implicates var2CSA, a member of the PfEMP1 family, as the mediator of placental sequestration and as a key target for PAM vaccine development. Var2CSA is...
Recognition of human erythrocytes by Plasmodium species depends in part on Region II of the Duffy binding-like family of parasite ligands, which includes BA erythrocyte binding ligand (BAEBL) of P. falciparum. In previous studies of BAEBL from two clones, Dd2/Nm from Vietnam and E12 from Papua New Guinea (PNG), it was found that BAEBL bound different erythrocyte receptors. Because of variation ...
