To determine whether morphologic changes are accompanied by variations in the biochemical and antigenic properties of the cuticle of Onchocerca volvulus during development, we isolated and compared the 2-mercaptoethanol soluble cuticular proteins and the insoluble cuticlin from the predominant
A preparation of the cuticle of Onchocerca volvulus was obtained by extracting worm fragments in an series of buffers with 1.5% Triton-X-100 and 3% Sodium dodecyl sulfate (SDS). Electron micrographs of worm fragments, treated with the detergents or collagenase showed that our methods had been
A divergent multi-domain cyclophilin from the filarial nematodes Brugia malayi, Onchocerca volvulus and Dirofilaria immitis has a highly conserved orthologue in the free-living nematodes Caenorhabditis elegans and C. briggsae. Cyclophilins are the receptors for the immunosuppressive and
Protective immunity against schistosomiasis induced by vaccination of mice with irradiated cercaria can be passively transferred to uninfected mice with sera or IgG. Antigens that are uniquely or more strongly recognized by such protective sera compared with sera from infected unprotected mice have
The gene encoding a C. elegans homologue of the mammalian reticuloplasmin, calreticulin, was cloned and sequenced and the amino-acid sequence of its product deduced. The coding region of the gene comprises three exons separated by introns of 95 and 55 nucleotides, followed by either 158 or 279 bases
Nodding syndrome (NS) is a devastating and enigmatic childhood epilepsy. NS is accompanied by multiple neurological impairments and neuroinflammation, and associated with the parasite Onchocerca volvulus (Ov) and other environmental factors. Moreover, NS seems to be an 'Autoimmune Epilepsy' since:
