Angiostrongylus cantonensis is the most common infectious cause of eosinophilic meningitis or meningoencephalitis. A novel gene (AC16) was isolated from a cDNA library of A. cantonensis fourth-stage larvae. The putative 16-kDa protein has 149 amino acids and is homologous to an immunodominant hypodermal antigen (IHA16) from Ancylostoma caninum (identities =(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)
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)
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)
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)
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)
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)
Macrophages as a principal component of immune system play an important role in the initiation, modulation, and final activation of immune response against pathogens including schistosomes. Classical (M1) or alternative (M2) activation states of macrophage have different functions during infections. Previously, we report that the schistosomal-derived(More)
Sj16, a 16-kDa protein secreted from Schistosoma japonicum, has been demonstrated an anti-inflammatory effect in vitro and in vivo, but its mechanism is still not clear. In this study, microarray analysis was performed to investigate the effects of recombinant Sj16 (rSj16) on the gene expression of the lipopolysaccharide (LPS)-stimulated dendritic cells(More)
Schistosoma japonicum is a major infectious agent of schistosomiasis. It has been reported that large number of proteins excreted and secreted by S. japonicum during its life cycle are important for its infection and survival in definitive hosts. These proteins can be used as ideal candidates for vaccines or drug targets. In this work, we analyzed the(More)
