Changes in the Epidemiology of Cutaneous Leishmaniasis in Northeastern Iran

Türkiye Parazitoloji Dergisi, 2020
The province of Khorasan-Razavi in the North East of Iran is an endemic area for anthroponotic cutaneous leishmaniasis (ACL caused mainly by Leishmania tropica) and zoonotic cutaneous leishmaniasis (ZCL caused mainly by Leishmania major).

Gelatin Zymography of Major Proteases in Exosomes of Leishmania major Promastigotes

Iranian Journal of Parasitology, 2023
Background: Enzymatic digestion of extra cellular matrix proteins by proteinases of   Leishmania promastigotes is a complex process. Hence, studies on functional proteomics of these enzymes can help select these enzymes as possible vaccine candidates or selecting candidates for chemotherapy and immunotherapy. Several proteolytic enzymes are involved in

Treatment outcome of imported cutaneous leishmaniasis among travelers and migrants infected with Leishmania major and Leishmania tropica: a retrospective study in European centers 2013 to 2019

International Journal of Infectious Diseases, 2022
: Objectives: Cutaneous leishmaniasis (CL) in Asia, Northern, and Sub-Saharan Africa is mainly caused by Leishmania major and Leishmania tropica. We describe and evaluate the treatment outcome of CL among travelers and migrants in Europe.

Histological and immunological differences between zoonotic cutaneous leishmaniasis due to Leishmania major and sporadic cutaneous leishmaniasis due to Leishmania infantum

Parasite, 2019
Lesion features in cutaneous leishmaniasis (CL) depend on the infecting Leishmania species as well as on host immune reponse. In this study, we evaluated the histological and immunological differences between two forms of CL described in Tunisia ...

Mixed Mucosal Leishmaniasis Infection Caused by Leishmania tropica and Leishmania major [PDF]

Journal of Clinical Microbiology, 2012
ABSTRACT Mixed infections with different Leishmania species could explain differences in the clinical courses of these infections. On identification of Leishmania parasites from Iranian patients with mucosal leishmaniasis (ML), a patient with both oral and nasal lesions was found to

High Throughput Screens Yield Small Molecule Inhibitors of Leishmania CRK3:CYC6 Cyclin-Dependent Kinase [PDF]

, 2011
Background: Leishmania species are parasitic protozoa that have a tightly controlled cell cycle, regulated by cyclin-dependent kinases (CDKs). Cdc2-related kinase 3 (CRK3), an essential CDK in Leishmania and functional orthologue of human CDK1, can form ...

Antileishmanial activity of polycyclic derivatives

Parasite, 2005
33 polycyclic derivatives have been studied and tested on Leishmania donovani and L. major promastigotes. Their antileishmanial activity was assessed in vitro and an assay of their cytotoxicity was realized on human myelomonocytic cell line.

Functional analysis of Leishmania major cyclophilin

International Journal for Parasitology, 2008
A potent immunosuppressive drug cyclosporin A (CsA) is known to inhibit human cell infection by the pathogenic protozoan parasite Leishmania major both in vitro and in vivo. The proposed mechanism of action involves CsA binding to Leishmania major-expressed cyclophilin and subsequent down-regulation of signaling events necessary for establishing ...

The crystal structure of the Borrelia burgdorferi nicotinamidase BBE22 resolves a long‐standing annotation error

FEBS Open Bio, EarlyView.
The crystal structure of Borrelia burgdorferi nicotinamidase (PncA/BBE22) reveals the correct full‐length protein initiated from a non‐canonical AUU start codon. The structure validates previous biochemical findings and resolves a long‐standing annotation error, demonstrating that the truncated database sequence is structurally incompatible with the ...
