Fecha de publicación: | 2019 | Editor: | Cambridge University Press | Citación: | Parasitology 146: 1743- 1754 (2019) | Resumen: | Kinetoplastid parasites are responsible for serious diseases in humans and livestock such as Chagas disease and sleeping sickness (caused by Trypanosoma cruzi and Trypanosoma brucei, respectively), and the different forms of cutaneous, mucocutaneous and visceral leishmaniasis (produced by Leishmania spp). The limited number of antiparasitic drugs available together with the emergence of resistance underscores the need for new therapeutic agents with novel mechanisms of action. The use of agents binding to surface glycans has been recently suggested as a new approach to antitrypanosomal design and a series of peptidic and non-peptidic carbohydrate-binding agents have been identified as antiparasitics showing efficacy in animal models of sleeping sickness. Here we provide an overview of the nature of surface glycans in three kinetoplastid parasites, T. cruzi, T. brucei and Leishmania. Their role in virulence and host cell invasion is highlighted with the aim of identifying specific glycan–lectin interactions and carbohydrate functions that may be the target of novel carbohydrate-binding agents with therapeutic applications. | Versión del editor: | http://dx.doi.org/10.1017/S0031182019001355 | URI: | http://hdl.handle.net/10261/212836 | DOI: | 10.1017/S0031182019001355 | Identificadores: | doi: 10.1017/S0031182019001355 issn: 0031-1820 e-issn: 1469-8161 |
