Molecular characterization and expression of Onchocerca volvulus glutathione reductase.

Glutathione metabolism represents a potential target for anti-parasite drug design. The central role of glutathione reductase (GR) in maintenance of the thiol redox state and in anti-oxidative defence has to be evaluated in more detail in order to establish the essential function of this enzyme for the survival of the filarial parasite Onchocerca volvulus. The O. volvulus GR (OvGR) gene was clo...

A novel type of glutathione S-transferase in Onchocerca volvulus.

Onchocerca volvulus is a pathogenic human filarial parasite which, like other helminth parasites, is capable of evading the host's immune responses by a variety of defense mechanisms which are likely to include the detoxification and repair mechanisms of the enzyme glutathione S-transferase (GST). In this study, we show that one of the previously described GSTs from O. volvulus appears to posse...

Molecular cloning of an immunodominant antigen of Onchocerca volvulus

We have cloned and characterized the gene for an immunodominant antigen of O. volvulus that is recognized by the sera of 96% of patients with onchocerciasis. Its 1.2-kb mRNA constitutes 0.3% of adult worm poly(A)+ RNA and its cDNA sequence reveals that it is not a highly conserved structural protein such as actin or tubulin. Similar but not identical genes occur in the genomes of related filari...

Molecular cloning of adenylate kinase from the human filarial parasite Onchocerca volvulus

Adenylate kinases (ADK) are ubiquitous enzymes that contribute to the homeostasis of adeninenucleotides in living cells. In this study, the cloning of a cDNA encoding an adenylate kinase from the filariaOnchocerca volvulus has been described. Using PCR technique, a 281 bp cDNA fragment encoding part ofan adenylate kinase was isolated from an O. volvulus cDNA library. Use of this fragment as a p...

Structural analysis and antibody response to the extracellular glutathione S-transferases from Onchocerca volvulus.

Onchocerca volvulus is a human pathogenic filarial parasite which, like other parasitic nematodes, is capable of surviving in an immunologically competent host by employing a variety of immune evasion strategies and defense mechanisms including the detoxification and repair mechanisms of the glutathione S-transferases (GSTs). In this study we analyzed the glycosylation pattern and the immunolog...
