چکیده

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 . methods: this experimental research was performed in the school of public health, tehran university of medical sciences, tehran, iran during 2007-2008.   a. palestinensis was grown on 2% non-nutrient agar overlaid with escherichia coli . dna extraction was performed using phenol-chloroform method. pcr reaction and amplification were done using specific primer pairs of mbp. the amplified fragment were purified and sequenced. finally, the obtained fragment was deposited in the gene data bank. results: a 900 bp pcr-product was recovered after pcr reaction. sequence analysis of the purified pcr product revealed a gene with 943 nucleotides. homology analysis of the ob­tained sequence showed 81% similarity with the available mbp gene in the gene data bank. the fragment was deposited in the gene data bank under accession number eu678895 conclusion : mbp is known as the most important factor in acanthamoeba pathogenesis cas­cade. therefore, characterization of this gene can aid in developing better therapeutic agents and even immunization of high-risk people.

molecular characterization and sequencing of a gene encoding mannose binding protein in an iranian isolate of acanthamoeba castellanii as a major agent of acanthamoeba keratitis

background: acanthamoeba castellanii is the important cause of amoebic keratitis in iran. the key molecule in pathogene­sis of acanthamoeba keratitis is mannose binding protein (mbp) led to adhesion of amoeba to corneal epithelium. subse­quent to adhesion other cytopathic effects occur. the goal of this study was to identify the molecular characterization of a gene encoding mbp in an iranian is...

Biochemical characterization and functional studies of Acanthamoeba mannose-binding protein.

Acanthamoebae produce a painful, sight-threatening corneal infection. The adhesion of parasites to the host cells is a critical first step in the pathogenesis of infection. Subsequent to adhesion, the parasites produce a potent cytopathic effect (CPE) leading to target cell death. Recent studies showing that acanthamoebae express a mannose-binding protein (MBP) and that free alpha-mannose (alph...

Introduction & Objective: Acanthamoeba is free-living amoeba that is found in soil, water, air as well as in human pharynx. Acanthamoeba is causative agent of granulomatose amoebic encephalitis (GAE) in immunosuppressed and AIDS individuals and amoebic keratitis in people who use the lens. Pathogenic species of Acanthamoeba have protein receptors named mannose binding protein (MBP). Acanthamo...

The Gly-54-->Asp allelic form of human mannose-binding protein (MBP) fails to bind MBP-associated serine protease.

The human mannose-binding protein (MBP) is a pattern recognition molecule that appears to play a role in initial host defence. MBP activates the complement cascade and it may act as an opsonin both in the absence and in the presence of complement. A number of distinct MBP allelic forms exist in different population groups. An allele that occurs in 5-7% of Caucasians was identified by an inabili...
