Structural Insights Into the Function of Leishmania major Adenylosuccinate Lyase

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT One of several intriguing aspects of kinetoplastid biochemistry is the complete dependence on host purines and purine recycling due to the lack of a de novo purine biosynthesis pathway. Adenylosuccinate lyase (ASL, EC 4.3.2.2) is a key enzyme in the purine synthesis pathway responsible for the conversion of adenylosuccinate into adenosine ...

Minor temperature shifts do not affect chromosomal ploidy but cause transcriptomic changes in Leishmania braziliensis promastigotes in vitro [PDF]

open access: yesMemorias do Instituto Oswaldo Cruz, 2020
BACKGROUND The leishmaniases are complex neglected diseases caused by protozoan parasites of the genus Leishmania. Leishmania braziliensis is the main etiological agent of cutaneous leishmaniasis in the New World. In recent studies, genomic changes such

Thymus and Leishmania at the Crossroads: Autoimmunity and Cancer

open access: yesImmunology, Volume 178, Issue 3, Page 377-386, July 2026.
Conceptual ‘Crossroads Model’ linking Leishmania, thymic infection and immune dysregulation: an integrative model is proposed in which Leishmania infection disrupts thymic architecture and stromal–thymocyte interactions. These alterations converge to promote defective tolerance, increased autoimmune risk and a microenvironment permissive to malignant ...

Is it time to revise the nomenclature of Leishmania?

open access: yes, 2010
Leishmania is notable for a large number of described species. Molecular phylogenies of Leishmania have increasingly suggested that the number of species could be too large.

Potential vectors of Leishmaniases in the Environmental Protection Area and Tinguá Federal Biological Reserve, Municipality of Nova Iguaçu, Rio de Janeiro, Brazil

open access: yesMedical and Veterinary Entomology, Volume 40, Issue 2, Page 246-259, June 2026.
This study was to describe the composition of sand fly fauna, detect potential vectors of Leishmania spp. in the Tinguá district, an ATL endemic, Rio de Janeiro, Brazil. Seven species of vectorial importance in the epidemiological cycle of leishmaniasis was observed: Nyssomyia intermedia, Migonemyia migonei, Pintomyia fischeri, Psychodopygus hirsutus ...

The role of leishmania proteophosphoglycans in sand fly transmission and infection of the Mammalian host. [PDF]

open access: yes, 2012
Leishmania are transmitted by the bite of their sand fly vector and this has a significant influence on the virulence of the resulting infection. From our studies into the interaction between parasite, vector, and host we have uncovered an important ...
