Arginine homeostasis and transport in the human pathogen Leishmania donovani.
Arginine is an essential amino acid for the human pathogen Leishmania but not to its host. Thus, the mechanism by which this protozoan parasite regulates cellular homeostasis of arginine is critical for its survival and virulence. In a previous study, we cloned and functionally characterized a high affinity arginine-specific transporter, LdAAP3, from Leishmania donovani. In this investigation, ...
متن کاملFunctionality of drug efflux pumps in antimonial resistant Leishmania donovani field isolates.
The recent upsurge of antimony (Sb) resistance is a major impediment to successful chemotherapy of visceral leishmaniasis (VL). Mechanisms involved in antimony resistance have demonstrated an upregulation of drug efflux pumps; however, the biological role drug efflux pumps in clinical isolates remains to be substantiated. Thus, in this study, the functionality of drug efflux pumps was measured ...
متن کاملAntimonial Resistance in Leishmania donovani Is Associated with Increased In Vivo Parasite Burden
Leishmania donovani is an intracellular protozoan parasite that causes visceral leishmaniasis (VL). Antimonials (SSG) have long been the first-line treatment against VL, but have now been replaced by miltefosine (MIL) in the Indian subcontinent due to the emergence of SSG-resistance. Our previous study hypothesised that SSG-resistant L. donovani might have increased in vivo survival skills whic...
متن کاملThiol-based redox metabolism of protozoan parasites.
The review considers redox enzymes of Plasmodium spp., Trypanosomatida, Trichomonas, Entamoeba and Giardia, with special emphasis on their potential use as targets for drug development. Thiol-based redox systems play pivotal roles in the success and survival of these parasitic protozoa. The synthesis of cysteine, the key molecule of any thiol metabolism, has been elucidated in trypanosomatids a...
