A significant amount of protein tyrosine phosphatase (PTP) activity was detected in the detergent-soluble membrane-bound fraction of Setaria cervi, a bovine filarial parasite. The membrane-bound PTP activity was significantly inhibited when the adult parasites were exposed to compounds having
Phenylarsine oxide (PAO), a specific protein tyrosine phosphatase (PTP) inhibitor significantly decreased the motility and viability of Setaria cervi ultimately leading to its death. The PTP activity present in the cytosolic and detergent soluble fractions as well as on surface of these parasites
BACKGROUND
Elimination of onchocerciasis and lymphatic filariasis is targeted for 2020. Given the coincident Loa loa infections in Central Africa and the potential for drug resistance development, the need for new microfilaricides and macrofilaricides has never been greater. With the genomes of L.
The glutathione reductase (GR) and thioredoxin reductase (TrxR) are important enzymes of the redox system that aid parasites to maintain an adequate intracellular redox environment. In the present study, the enzyme activity of GR and TrxR was investigated in Setaria cervi (S. cervi). Significant
Thioredoxin reductase plays a crucial role in the maintenance of cellular redox homeostasis. In this study, we have targeted TrxR in Setaria cervi, a bovine filarial parasite using its inhibitor CDNB. It caused significant decrease in the motility and viability of these parasites leading to their
The carbohydrate polymer inspired silver nanoparticles (AgNPs) are designed and synthesized through ultrasound assisted green process using unique combination of a biomolecule (tyrosine) and a natural polymer (starch). A comprehensive mechanistic study on the reactive oxygen species (ROS) mediated
Albendazole, anthelmintic benzimidazole (BZ) is being co-administered with an antifilarial drug, diethylcarbamazine (DEC), in lymphatic filariasis (LF) elimination programmes. But this drug is known to result in the faster development of drug resistance and hence it is necessary to monitor drug
Circulating filarial proteins elicit strong immunologic reactions in humans leading to the chronic manifestations in human lymphatic filariasis such as lymphatic occlusion, fibrosis, edema, and in some cases, tropical pulmonary eosinophilia. Our earlier studies, in vitro, conclusively prove that
Human lymphatic filariasis (LF) is mainly caused by filarial parasite Wuchereria bancrofti and is the second leading cause of long term and permanent disability in tropical countries. To date, incapability to eliminate long lived adult parasites by current drugs remains the major challenge in the
BACKGROUND
Current available antifilarial drug strategies only eliminate the larval stages of filarial parasites. Therefore, there is an urgent need of drugs which are macrofilaricidals. Identification of molecular targets crucial for survival of parasite is a prerequisite for drug designing.
The Global Program to Eliminate Lymphatic Filariasis has been implemented to reduce human microfilaremia to levels low enough to break the transmission of the disease by using single annual doses of albendazole in combination with diethylcarbamazine or ivermectin. Many veterinary helminth parasites
