Project description:This parasitic filarial worm causes lymphatic filariasis and elephantiasis in humans
| PRJNA12862 | ENA
Project description:Filarial nematodes are arthropod-borne nematodes that cause a variety of economically important diseases such as onchocerciasis (river blindness), lymphatic filariasis, and heartworm disease. The most widespread filarial disease of humans is lymphatic filariasis, caused by worms in the genera Wuchereria and Brugia. Lymphatic filariasis is an economic and social burden in endemic countries and affects approximately 119 million people worldwide (Michael, 1997). In humans, the worms live in and block the lymph vessels, causing improper flow of lymph, and inflammation of the lymphatic system. The symptoms are fever, swollen limbs and genitals, generalized malaise, and can progress to a debilitating condition known as elephantiasis This research focuses on the transmission of these worms to the disseminating mosquito host, and it is based on the interesting observation that mf must be at least 7 days old to successfully infect the mosquito (de Hollanda, 1982). Newborn mf that have not âmaturedâ cannot successfully penetrate the midgut of the mosquito, and subsequently cannot develop to the L3 stage (Fuhrman, 1987). Previous work done by another group 20 years ago suggests that the molecular makeup of the worm surface changes during this maturation process (Furman, 1983 a and b). We used microarray analysis to characterize changes in gene expression that take place during the mf maturation process. Understanding the gene expression changes that occur as the mf mature will allow us to understand the nature of the philological transition that allows mf to move from the human to the mosquito host. With this information in hand, we can eventually identify parasite molecules that could be targeted to either stop parasite reproduction or prevent transmission of the mf to the mosquito. This would stop parasite transmission in endemic areas. Two biological replicates were performed each with two technical replicates.

Project description:Rapid and accurate prevalence mapping of lymphatic filariasis (LF) is necessary to eliminate this disfiguring and disabling neglected tropical disease. Unfortunately, rapid tests such as the filariasis test strip (FTS) for Wuchereria bancrofti, the causative agent of LF in Africa, can cross-react with antigens circulating in some persons infected by the African eye worm, Loa loa, rendering the test unreliable in eleven co-endemic nations. The intended target of the FTS is a heavily glycosylated W. bancrofti circulating filarial antigen (Wb-CFA). Previously, we determined that the FTS monoclonal antibody, AD12.1, which detects a carbohydrate epitope on Wb-CFA, also detects multiple L. loa proteins in cross-reactive sera from persons with loiasis. Since the carbohydrate epitope recognized by AD12.1 is present on glycoproteins of other parasitic nematodes, including Brugia species, it is unclear why reactive glycoproteins are not detected in infections with other filarial parasites. To gain a better understanding of the proteins recognized by the FTS diagnostic antibody, we used proteomics and to characterize filarial glycoproteins that are bound by the AD12.1 antibody using Brugia malayi as a model. This included using shotgun proteomics to catalog the AD12-reactive glycoproteins found in adult female somatic (BmSOM) and excretory/secretory (BmES) antigens. As well as in-gel proteomics of two predominant protein bands from BmES.

Project description:Brugia malayi is a parasitic nematode that causes lymphatic filariasis in humans. A total of 178 novel microRNA were identified from short read transcriptional data, which when combined with known Brugia microRNAs yielded a total of 284 microRNA. Of these, 123 microRNA sequences (43%) are differentially expressed over the mammalian life stages of B. malayi that we examined. Putative targets of these microRNA were identified from inversely expressed target clusters that contain valid seed sequences for the corresponding microRNAs. The largest identified cluster is downregulated in adult females and enriched in zinc finger domains, helicase domains, and DNA binding domains suggesting this microRNA cluster may have regulatory control over a large proportion of adult female specific mRNA genes. MicroRNA-like molecules are identified as produced by the Wolbachia endosymbiont, providing evidence for direct nucleic acid-based interdomain communication between filarial nematodes and their bacterial obligate endosymbiont.
