Schistosomes are the causative agent of schistosomiasis. The 70-kDa heat-shock proteins (HSP70) are considered the predominant HSP family and play a key regulatory role in parasite development and pathogenesis. Based on the published sequences in Genbank/EMBL, an open-reading frame (ORF) encoding 653 amino acids (XP_002581385.1) and belonging to the(More)
Parasites including helminthes, protozoa, and medical arthropod vectors are a major cause of global infectious diseases, affecting one-sixth of the world’s population, which are responsible for enormous levels of morbidity and mortality important and remain impediments to economic development especially in tropical countries. Prevalent drug resistance, lack(More)
A full-length cDNA encoding a cercarial stage-specifically expressed 8-kDa calcium-binding protein (SjCa8) was isolated from Schistosoma japonicum cercarial cDNA library using microarray screen. The putative gene coding for SjCa8 is of 371 bp with an open reading frame of 69 amino acid (aa). The deduced aa sequence showed 83% identity with the Schistosoma(More)
Schistosoma japonicum is the pathogen responsible for schistosomiasis japonica, one of the major infectious diseases targeted for prevention nationally in China. Expression of heat shock proteins (HSPs) following stress plays a very important biological role in many organisms including S. japonicum. Among the HSP family, the 70-kDa HSPs are most responsible(More)
The pathogenesis of angiostrongyliasis, resulting from the third-stage and the fourth-stage Angiostrongylus cantonensis larvae invasion of the human central nervous system, remains elusive. MicroRNAs are important regulators of gene expression and involved in many biological processes. The aim of this study was to determine and characterize miRNAs of third(More)
Increasing evidence shows that microRNAs (miRNAs) are a family of regulatory molecules involved in many physiological processes, including the inflammation in central nervous system (CNS) and neurological disorders. Angiostrongylus cantonensis (A. cantonensis) is the major cause of human infectious eosinophilic meningitis and can induce CNS injury. In the(More)
Angiostrongylus cantonensis is an emerging zoonotic pathogen that has caused hundreds of cases of human angiostrongyliasis worldwide. The larva in nonpermissive hosts cannot develop into an adult worm and can cause eosinophilic meningitis and ocular angiostrongyliasis. The mechanism of brain inflammation caused by the worm remains poorly defined. According(More)
Schistosomiasis is a water-borne infection caused mainly by human schistosomes including Schistosoma mansoni (S. mansoni) and Schistosoma japonicum (S. japonicum). In the infected host, immune events in the skin appear to have an important initiating role in determining the type, and guiding the magnitude, of the ensuing acquired immune response. The(More)
Angiostrongylus cantonensis invasion primarily cause heavy or negligible eosinophic meningitis and meningoencephalitis in the brain of non-permissive and permissive hosts, respectively. Chemokines are effective leukocyte chemoattractants and may play an essential role in mediating eosinophil recruitment in angiostrongyliasis. In the present study, we(More)
Angiostrongyliasis, caused by Angiostrongylus cantonensis infection, is a food-borne parasitic disease. Its larvae evoke eosinophilic inflammation in the central nervous system, but can also cause pathological changes in the eyes. Among ocular angiostrongyliasis cases, the incidence of optic neuritis is low and only few sporadic reports exist. Some patients(More)
