Antiviral Nucleoside Inhibitors Of Leishmania Rna Virus 1: Discovery And Mechanism, John Isaac Robinson
Antiviral Nucleoside Inhibitors Of Leishmania Rna Virus 1: Discovery And Mechanism, John Isaac Robinson
Arts & Sciences Electronic Theses and Dissertations
Some Leishmania parasites in the Viannia sub-genus are persistently infected with Leishmania RNA virus 1 (LRV1), a single-segmented double-stranded RNA virus belonging to the family Totiviridae. Infected parasites cause greater pathology and reach higher populations in mouse models of Leishmania infection. In human disease, LRV1+ parasites are correlated with increased frequency of treatment failure and relapse. Efficient methods to detect LRV1 and eliminate it from parasites are required to better understand the role of LRV1 in Leishmania infection. We optimized multiple techniques to measure LRV1 levels in parasites, most notably using flow cytometry to measure the amount of viral capsid …

The presence of Leishmania RNA virus 1 (LRV1) in parasites of the Leishmania (Viannia) subgenus increases the virulence of the parasite in mouse models of leishmaniasis and is correlated with treatment failure, relapse, and the development of mucocutaneous disease in humans. LRV1 is not shed or infectious; rather, the infection is persistent, and as yet it is unknown how the parasite controls virus levels. Many eukaryotic organisms use RNA interference (RNAi) to limit virus replication, and Leishmania (Viannia) parasites have an active RNAi pathway. To determine whether Leishmania are capable of using RNAi to control LRV1, we sequenced sRNAs from …
