The potential of PLGA-nanoparticles as a carrier of amphotericin B and doxorubicin against visceral leishmaniasis was evaluated by macrophage-mediated drug targeting approach. PLGA-nanoparticles were modified by coating them with macrophage-specific ligand-lectin. Prior to in-vitro studies, characterization studies were carried out systematically include particle size, surface morphology, perce...

iranian castor bean lectin was isolated and purified by several column chromatography methods. then, the sugar and amino acid content of the purified lectin was identified. castor bean lectin has some anti tumor and anti leukemia action. thus it may be used commercially for medical and biochemical purposes.

Gold nanoparticles and gold nanoshells functionalised with a selection of carbohydrates: glyco-nanoparticles towards lectin detection in dipstick assay.

Photochemotherapy is used both for solid tumors and in extracorporeal treatment of various hematologic disorders. Nevertheless, its development in oncology remains limited, because of the low selectivity of photosensitizers (PS) towards human tumor cells. To enhance PS efficiency, we recently covalently linked a porphyrin (TrMPyP) to a plant lectin (Morniga G), known to recognize with high affi...

One of the important parts of innate immunity is complement system that occurs in three different ways; the classic, the alternative and the lectin pathway. The four pattern recognition molecules that have been identified till now are Mannose binding lectin (MBL), a component of lectin pathway, and three ficolins (ficolin1,-2 and -3) which compound to the carbohydrates of the cell surface. MBL ...

MODIFICATIONS IN RABBIT SPERM PLASMA MEMBRANES DURING EPIDIDYMAL PASSAGE AND AFTER EJACULATION WERE INVESTIGATED BY USED OF THREE LECTINS: concanavalin A (Con A); Ricinus communis I (RCA(I)); and wheat germ agglutinin (WGA). During sperm passage from caput to cauda epididymis, agglutination by WGA drastically decreased, and agglutination by RCA(I) slightly decreased, although agglutination by C...

Lectin from the bulbs of Cyclamen mirabile which is an endemic species Turkey was successfully isolated by affinity precipitation with alginate in one step. The purified protein produced two bands showing a dimeric structure SDS-PAGE (13.5 and 14.8 kDa). C. lectin showed activity stability broad pH scale kept its haemagglutination temperature range 4-40°C. MgCl2 HgCl2 inhibited lectin. In this ...

background: fascioliasis is a chronic hepatic disease and may be resulted from mechani­cal/molecular parasite adhesion to host liver tissue. the aim of this study was to detect surface car­bohydrate and lectin, carbohydrate-binding protein isolation that might be responsible of this molecular binding. methods: the present experimental work was conducted in the department of medical parasitol­og...

background: lectins the multivalent carbohydrate binding proteins are also employed to ascertain differentiation and characterization of the specific cell surface carbohydrate ligands/ receptors of different cell types including spermatozoa and posses novel biomedical importance. objective: sf50 the sialic acid specific lectin was employed on goat cauda epididymal spermatozoa to investigate its...

altered glycosylation of proteins in cancer cells is one of the main processes responsible for anaplasia, invasion and metastatic potential of neoplastic cells. lectins are nonimmunogenetic compounds which specifically detect certain terminal sugars of glycoconjugates. the aim of the present study was to identify the n-acetylgalactosamine (galnac) containing glycoconjugates in cancer cells in a...
