Characterization of a Novel Putative S-Adenosylmethionine Decarboxylase-Like Protein from Leishmania donovani. [PDF]

PLoS ONE, 2013
In addition to the S-adenosylmethionine decarboxylase (AD) present in all organisms, trypanosomatids including Leishmania spp. possess an additional copy, annotated as the putative S-adenosylmethionine decarboxylase-like proenzyme (ADL).

Leishmania mortality in sand fly blood meal is not species-specific and does not result from direct effect of proteinases

Parasites & Vectors, 2018
Background Leishmania development in sand flies is confined to the alimentary tract and is closely connected with blood meal digestion. Previously, it has been published that activities of sand fly midgut proteases are harmful to Leishmania, especially ...

Leishmania -infected macrophages release extracellular vesicles that can promote lesion development

Life Science Alliance, 2020
Macrophages infected with Leishmania donovani release extracellular vesicles that are composed of parasite and host-derived molecules that have the potential to induce vascular changes in tissues.

Autochthonous Leishmaniasis Caused by Leishmania tropica, Identified by Using Whole-Genome Sequencing, Sri Lanka

Emerging Infectious Diseases
Cutaneous leishmaniasis is atypical in Sri Lanka because Leishmania donovani, which typically causes visceral disease, is the causative agent. The origins of recently described hybrids between L. donovani and other Leishmania spp.

Enhanced Glycolysis Is Required for Antileishmanial Functions of Neutrophils Upon Infection With Leishmania donovani

Frontiers in Immunology, 2021
Visceral leishmaniasis (VL) is a fatal parasitic disease if untreated. Treatment options of VL diminish due to emerging drug resistance. Although the principal host cells for the multiplication of Leishmania are macrophages, neutrophils are the first ...

Structural Insights Into the Function of Leishmania major Adenylosuccinate Lyase

Proteins: 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 ...

Cathepsin B gene disruption induced Leishmania donovani proteome remodeling implies cathepsin B role in secretome regulation. [PDF]

PLoS ONE, 2013
Leishmania cysteine proteases are potential vaccine candidates and drug targets. To study the role of cathepsin B cysteine protease, we have generated and characterized cathepsin B null mutant L. donovani parasites. L.

Proteomic analysis of the secretome of Leishmania donovani [PDF]

Genome Biology, 2008
Abstract Background Leishmania and other intracellular pathogens have evolved strategies that support invasion and persistence within host target cells. In some cases the underlying mechanisms involve the export of virulence factors into the host cell cytosol.

HetCA/STOCSY‐Guided Dereplication of Artemisia arborescens Reveals Furofuran Lignans with Antileishmanial Effects

ChemMedChem, Volume 21, Issue 15, 14 August 2026.
Bioactive metabolites can remain hidden in negligible activity extracts. A statistical spectroscopy–driven dereplication workflow integrating the HeteroCovariance Approach (HetCA) and Statistical Total Correlation Spectroscopy (STOCSY) prioritized furofuran lignans in Artemisia arborescens, identifying three compounds with moderate antileishmanial ...

Identification of a Benzenesulfonylpiperazine Derivative With In Vivo Efficacy Against Visceral Leishmaniasis

Chemical Biology &Drug Design, Volume 108, Issue 2, August 2026.
This work highlights the satisfactory pharmacokinetic profile of two benzenesulfonylpiperazine lead candidates, followed by in vivo assessment in a murine model of visceral leishmaniasis. This assessment identified compound 2 as moderately active at a lower dose, but its efficacy increased at higher doses, though with concerns regarding safety.
