Cysteine proteases play essential roles in parasite physiology as well as in host-parasite interactions through their modulation of various biological and pathobiological events. In the present study, a full-length sequence encoding cysteine protease of Clonorchis sinensis (CsCP) was isolated from
BACKGROUND
Human clonorchiasis is a prevailing food-borne disease caused by Clonorchis sinensis infection. Functional characterizations of key molecules from C. sinensis could facilitate the intervention of C. sinensis associated diseases.
METHODS
In this study, immunolocalization of C. sinensis
Clonorchiasis remains a nonnegligible public health problem in endemic areas. Cysteine protease of Clonorchis sinensis (CsCP) plays indispensable roles in the parasitic physiology and pathology, and has been exploited as a promising drug and vaccine candidate. In recent years, development of
Clonorchiasis, a food-borne zoonosis, is caused by Clonorchis sinensis. The intestinal tract and bile ducts are crucial places for C. sinensis metacercariae to develop into adult worms. The endospore of Bacillus subtilis is an ideal oral immunization vehicle for delivery of heterologous antigens to
OBJECTIVE
To compare the prokaryotic expression system and eukaryotic expression system for the expression of cysteine protease of Clonorchis sinensis, and the diagnostic efficiency of their objective products.
METHODS
According to the sequence of cysteine protease of C. sinensis, two pairs of
BACKGROUND
Cathepsin cysteine proteases play multiple roles in the life cycle of parasites such as food uptake, immune invasion and pathogenesis, making them valuable targets for diagnostic assays, vaccines and drugs. The purpose of this study was to identify a cathepsin B of Clonorchis sinensis
Cathepsin L of parasite plays multiple roles in growth, food uptake, and invasion into host and pathogenesis, which makes it a valuable target for diagnosis, vaccine, and drug. In this study, we identified a cDNA encoding cathepsin L homolog (CsCPL) from the library of Clonorchis sinensis adult by
OBJECTIVE
To clone and express the cysteine protease of Clonorchis sinensis and evaluate its effect on immunodiagnosis of human clonorchiasis.
METHODS
Based on a cysteine protease gene fragment of C. sinensis (CS-CP, GenBank accession: AF093242), a pair of primers were designed and amplified from
Taenia solium metacestode, a larval pork tapeworm, is a causative agent of neurocysticercosis, one of the most common parasitic diseases in the human central nervous system. In this study, we identified a cDNA encoding for a cathepsin L-like cysteine protease from the T. solium metacestode (TsCL-1)
Clonorchis sinensis, the Chinese liver fluke, is a trematode parasite that causes clonorchiasis in humans. In this study, we identified a novel gene encoding a cathepsin F-like cysteine protease of C. sinensis (CsCF-6) and characterised its role in nutrient uptake by the parasite. Sequence and
Cysteine proteases (CPs) were associated with the pathogenicity and excystment of Clonorchis sinensis. Most of them were potential antigens for the immunodiagnosis of clonorchiasis. More researches on CPs will let us know more about their functions, and further employ them for the development of
Clonorchiasis, which has been an important public health problem in China, is caused by ingestion of raw or undercooked fish contaminated by live metacercaria. Therefore, preventing fish from infecting is of great significance for controlling the disease. SERPINs (serine protease inhibitors) are
A novel 28 kDa cysteine protease (Cs28CF) secreted by the hepatobiliary trematode, Clonorchis sinensis was identified. The protease was purified from the excretory-secretory products (ESP) of the adult worm using DEAE-ion exchange and Arginine-Sepharose 4B chromatography. It showed a high activity
Clonorchis sinensis, the causative agent of clonorchiasis, is widespread in East and Southeast Asia, including China, Vietnam and the Republic of Korea. We identified antigenic proteins from adult C. sinensis liver flukes using immunoproteomic analysis. In this study, we found 23 candidate antigenic
Paragonimiasis, caused by the lung fluke Paragonimus, is a major food-borne helminthic disease. Differential diagnosis of paragonimiasis from tuberculosis and other infectious granulomas in the lung is a prerequisite to proper management of patients. Cysteine proteases of Paragonimus westermani
