background: analysis of human cancer serum has revealed the presence of high amounts of hyaluronan (hyaluronic acid, ha) when compared to human normal serum, it is well documented that ha and its receptors, known as hyaladherins (habps) are involved in matrix regulation, cell proliferation, migration and malignant tumour progression. these hyaladherins not only interact with hyaluronan at the m...

ba ckground: obesity is a consequence of the excessive accumulation of fat in adipose tissue which can result in significant morbidity and mortality. obesity is a major health problem in iran.  objective: the aim of this study was to investigate the  effects of  epa consumption on bmi  and  fasting blood sugar by fabp2 genotypes and pparα (leu162val, and g/c intron polymorphism) genotypes.   m ...

Neuronal survival and morphological maturation depends on the action of the transcription factor calcium responsive element binding protein (CREB), which regulates expression of several target genes in an activity-dependent manner. However, it remains largely unknown whether CREB-mediated transcription could play a role at early stages of neuronal differentiation, prior to the establishment of ...

The Atypical ChemoKine Receptor 1 (ACKR1) gene, better known as Duffy Antigen Receptor for Chemokines (DARC or Duffy), is responsible for the Duffy Blood Group and plays a major role in regulating the circulating homeostatic levels of pro-inflammatory chemokines. Previous studies have shown that one common variant, the Duffy Null (Fy-) allele that is specific to African Ancestry groups, complet...

Malaria parasite antigens involved in erythrocyte invasion are primary vaccine candidates. The erythrocyte-binding antigen 175K (EBA-175) of Plasmodium falciparum binds to glycophorin A on the human erythrocyte surface via an N-terminal cysteine-rich region (termed region II) and is a target of antibody responses. A survey of polymorphism in a malaria-endemic population shows that nucleotide al...

Plasmodium falciparum malaria is a major cause of mortality and severe morbidity. Its virulence is related to the parasite's ability to evade host immunity through clonal antigenic variation and tissue-specific adhesion of infected erythrocytes (IEs). The P. falciparum erythrocyte membrane protein 1 (PfEMP1) family is central to both. Here, we present evidence of a P. falciparum evasion mechani...

Invasion of human erythrocytes by the malaria parasite Plasmodium falciparum utilizes multiple ligand-receptor interactions involving erythrocyte receptors and parasite erythrocyte binding proteins of the Duffy binding-like family. Erythrocyte binding antigen 175 (EBA-175) binds to glycophorin A, the most abundant protein on the human erythrocyte surface and EBA-140 (also known as BAEBL) binds ...
