Virus-Induced Lysis of Tumor and Other Pathogenic Unicellular Entities and Its Potential to Treat Leishmaniasis.

This article is focused on the main pathways used by viruses to achieve infection and lysis of unicellular eukaryotes described as pathogenic for multicellular organisms. In light of the recent discussions on how tumor cells exhibit unicellular behavior, highly malignant cells can be considered as another unicellular pathogenic entity, but with endogenous origin. Thus, a comparative panel of viral lysis of exogenous pathogenic unicellular eukaryotes such as Acanthamoeba sp. , yeast, and tumors is presented. The important intracellular parasite Leishmania sp is also presented, which, in contrast, has its virulence improved by viral infections. The possible exploitation of viral-mediated eukaryotic cell lysis to overcome infections of Leishmania sp is discussed.
