results in this study, 45 (13.4 %) urine samples were positive for candida species (17 males and 28 females). the most common isolated yeast was candida albicans (34%), followed by c. glabrata (32.1%), c. tropicalis (9.4%), other candida species (22.6%), and rhodotorula species (1.9%). the mean serum levels of mbl were 0.85 ± 0.01 ng/ml and 1.02 ± 0.03 ng/ml among candiduric patients and contro...

Mannan-binding protein (MBP) is a C-type serum lectin and activates complement through the lectin pathway when it binds to ligand sugars such as mannose, N-acetylglucosamine, and fucose on microbes. In addition, the vaccinia virus carrying the human MBP gene was shown to exhibit potent growth inhibitory activity toward human colorectal carcinoma, SW1116, cells in nude mice. We have proposed cal...

A modular platform for targeted delivery was based on a single chain variable (ScFv) fragment fused to maltose-binding protein (MBP). Using different maltosylated ligands it is likely target, transport drugs, or deliver genes specific cells.

mannose-binding lectin (mbl) is a protein of innate immune system that is involved in opsonization and complement activation. mbl deficiency is associated with predisposition to infectious diseases; however subnormal levels are also seen in healthy subjects. the aim of this study was to investigate the prevalence and clinical manifestation of mbl deficiency in patients with increased susceptibi...

A portion of rat mannose-binding protein A (MBP-A), a Ca(2+)-dependent animal lectin, has been overproduced in a bacterial expression system, biochemically characterized, and crystallized. A fragment corresponding to the COOH-terminal 115 residues of native MBP-A, produced by subtilisin digestion of the bacterially expressed protein, contains the carbohydrate-recognition domain (CRD). Gel filtr...

CD69 is a widely expressed type II transmembrane glycoprotein related to the C-type animal lectins that exhibits regulated expression on a variety of cells of the hematopoietic lineage, including neutrophils, monocytes, T cells, B cells, natural killer (NK) cells, and platelets. Activation of T lymphocytes results in the induced expression of CD69 at the cell surface. In addition, cross-linking...

BACKGROUND Acanthamoeba keratitis develops by pathogenic Acanthamoeba such as A. palestinensis. Indeed this species is one of the known causative agents of amoebic keratitis in Iran. Mannose Binding Protein (MBP) is the main pathogenicity factors for developing this sight threatening disease. We aimed to characterize MBP gene in pathogenic Acanthamoeba isolates such as A. palestinensis. METHO...

Surfactant protein (SP) A and SP-D are the pulmonary members of the collectin family, structurally related proteins involved in innate immune responses. Here, we have examined the abilities of SP-A, SP-D, mannose-binding protein (MBP), and the complement component C1q to stimulate actin-based cellular functions in rat alveolar macrophages and peripheral blood monocytes. Our goal in this study w...

a sweet water-soluble protein that reminds stable over wide ranges of temperature and ph, brazzein has various applications. its tastes like cane sugar but have no calories. however, the extraction of brazzein from its natural source is expensive and not applicable. in this study we used recombinant dna technology to provide an alternative option for cheaper mass production of brazzein. a brazz...

The OleB protein of Streptomyces antibioticus, oleandomycin (OM) producer, constitutes an ATP-binding cassette transporter containing two nucleotide-binding domains and is involved in OM resistance and its secretion in this producer strain. We have characterized some properties of the first nucleotide-binding domain of OleB using an overexpressed fusion protein (MBP-OleB') between a maltose-bin...
