OBJECTIVES Treatment failure is multifactorial. Despite the importance of host cell drug transporters and metabolizing enzymes in the accumulation, distribution and metabolism of drugs targeting intracellular pathogens, their impact on the efficacy of antileishmanials is unknown. We examined the contribution of pharmacologically relevant determinants in(More)
Chronic tegumentary leishmaniasis is characterized by a scarcity of parasites in lesions and a heightened inflammatory response. Deregulated and hyperactive inflammation contributes to tissue damage and parasite persistence. The mechanisms by which immune cells are recruited to the lesion and their relationship to clinical outcomes remain elusive. We(More)
Within its mammalian host, Leishmania resides and replicates as an intracellular parasite. The direct activity of antileishmanials must therefore depend on intracellular drug transport, metabolism, and accumulation within the host cell. In this study, we explored the role of human macrophage transporters in the intracellular accumulation and antileishmanial(More)
