Intracellular localization of LRV1 in infected Leishmania cells and epitope conservation of the coat protein.
Polyclonal antibodies were raised against a recombinant fragment of the coat protein of LRV1-1 to determine the epitope conservation of the coat protein among LRV1 isolates, and the intracellular localization of LRV1 particles in promastigote cells of Leishmania braziliensis. Western blot analysis showed that specific epitopes of the coat protein are highly conserved among isolates from different geographic areas. Using indirect immunofluorescence assays LRV1 viral particles were observed as fluorescent granules, limited to the cytoplasm and with no apparent association to the host organelles or the cell membrane, characteristic of a persistent, non-infectious virus.
