Innate Immune B Cell Activation by Leishmania donovani Exacerbates Disease and Mediates Hypergammaglobulinemia

open access: yesCell Reports, 2016
Participation of B cells in the immune response by various antibody-independent mechanisms has recently been uncovered. B cells producing cytokines have been described for several infections and appear to regulate the adaptive immune response.

Asymptomatic Leishmania donovani infection and associated factors among blood donors attending at Metema district Blood Bank, Northwest Ethiopia: a cross- sectional study

open access: yesArchives of Public Health, 2023
Background Ethiopia is one of the top 10 countries in the world where 90% visceral leishmaniasis cases are reported. Metema-Humera lowlands are the most important foci in Ethiopia. Blood transfusion in visceral leishmaniasis endemic foci in Ethiopia does

Adenine and adenosine salvage in Leishmania donovani [PDF]

open access: yesMolecular and Biochemical Parasitology, 2013
6-aminopurine metabolism in Leishmania is unique among trypanosomatid pathogens since this genus expresses two distinct routes for adenine salvage: adenine phosphoribosyltransferase (APRT) and adenine deaminase (AAH). To evaluate the relative contributions of APRT and AAH, adenine salvage was evaluated in Δaprt, Δaah, and Δaprt/Δaah null mutants of L ...

Recombinant LPG3 Protein From Leishmania chagasi as an Antigen for the Diagnosis of Canine Visceral Leishmaniasis

open access: yesTropical Medicine &International Health, Volume 31, Issue 8, Page 1057-1065, August 2026.
ABSTRACT Visceral leishmaniasis (VL) is a human neglected tropical disease in which dogs participate as reservoirs of the etiological agent Leishmania chagasi. The identification of infected dogs is important to the control of VL, and recombinant proteins are strong antigen candidates for canine visceral leishmaniasis (CVL) serodiagnosis. In this work,

CRISPR-Cas9-Mediated Genome Editing in Leishmania donovani

open access: yesmBio, 2015
The prokaryotic CRISPR (clustered regularly interspaced short palindromic repeat)-Cas9, an RNA-guided endonuclease, has been shown to mediate efficient genome editing in a wide variety of organisms.

Carbon Dioxide Assimilation by Leishmania donovani [PDF]

open access: yesNature, 1960
WHILE studying the glucose metabolism of Leishmania donovani, the protozoan organism causing visceral leishmaniasis, it has been found that cell suspensions of this organism in a saline-bicarbonate buffer containing glucose can assimilate, a measurable amount of carbon dioxide along with the formation of different acidic end products1.

IL‐33/ST2 Signaling Sustains Hepato‐Intestinal Homeostasis by Orchestrating Vascular Surveillance and Immune Regulatory Circuits During Experimental Trypanosoma cruzi Infection

open access: yesThe FASEB Journal, Volume 40, Issue 13, 15 July 2026.
Impairment of hepato‐intestinal homeostasis triggered by ST2 deficiency during T. cruzi infection. Within the splenic compartment, immune dysregulation is marked by a robust pro‐inflammatory polarization of the T‐cell landscape. In the liver, ST2 deficiency is associated with hepatocellular injury, increased parasite burden, and hyperalbuminemia ...

Probing 5‐Nitroimidazole‐Triazole Hybrids as Potential Anti‐Kinetoplastid Agents: Synthesis and In Vitro Efficacy

open access: yesChemMedChem, Volume 21, Issue 13, 14 July 2026.
A series of 5‐nitroimidazole‐1,2,3‐triazole hybrids was synthesised and evaluated for antitrypanosomatid activity to assess their potential as treatments against leishmaniasis and trypanosomiasis. No notable in vitro activity against Leishmania was detected.
