Abstract: Infections caused by protozoan parasites are one of the most important public health problems in developing
countries. One approach to design new drugs for these parasitic diseases relies on metabolic and molecular features which
are ideally absent in mammalian hosts. Out of them, nutrient transporters play an important role since they were subjected
to millions of years of adaptation to parasitism, in which this protozoan replaced many biosynthetic routes for transport
systems. Here we address the current knowledge of trypanosomatids transport systems and the molecules related to such
processes, including a description of permeases involved in drug uptake, and also those responsible of drug resistance.
The latter process produces, in many cases, the treatment failure due to the loss of the transporter function, as is the case
of eflornithine, as well as by increasing the extrusion of drugs, in which usually ABC-type transporters are involved. All
these aspects and the perspectives on this topic are briefly updated in this review.
