Distinct roles in autophagy and importance in infectivity of the two ATG4 cysteine peptidases of leishmania major [PDF]

open access: yes, 2013
Macroautophagy in Leishmania, which is important for the cellular remodeling required during differentiation, relies upon the hydrolytic activity of two ATG4 cysteine peptidases (ATG4.1 and ATG4.2).

Functional analysis of Leishmania major cyclophilin

open access: yesInternational 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 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 ...

Reinfection in American Cutaneous Leishmaniasis: Evaluation of Clinical Outcomes in the Hamster Model [PDF]

open access: yesMemorias do Instituto Oswaldo Cruz, 1998
There is no clear understanding of the outcome of reinfection in New World cutaneous leishmaniasis, and its role in the relationship to the development of protection or secondary disease.

New Insights Into the Three‐Dimensional Mechanics of the Flagellar Beat Cycle

open access: yesCytoskeleton, EarlyView.
ABSTRACT Advances in imaging at the molecular scale have provided greater detail concerning the three‐dimensional structure of the ciliary/flagellar axoneme. Additionally, it has recently been confirmed that electrostatic forces regulate the dynein‐tubulin interaction at the microtubule binding domain (MTBD) of dynein, and at the junction of the nexin ...

Inhibition of pteridine reductase 1 (PTR1) expression in Leishmania promastigotes using a full-length antisense construct [PDF]

open access: yes, 2009
Leishmania exhibit many unusual features, one of which is the pteridine metabolic pathway essential for the growth for these parasites. Leishmania have evolved a complex and versatile pteridine salvage network capable of scavenging a wide array of ...

Predominance of Leishmania major and rare occurrence of Leishmania tropica with haplotype variability at the center of Iran

open access: yesBrazilian Journal of Infectious Diseases, 2018
Background: Leishmania major is a causative agent of zoonotic cutaneous leishmaniasis in the center of Iran, Abarkouh district. Molecular characterization and precise incrimination of Leishmania species was carried out to perform controlling measurements

Heterogeneity of cysteine proteinases in Leishmania braziliensis and Leishmania major.

open access: yesBrazilian journal of medical and biological research = Revista brasileira de pesquisas medicas e biologica, 1994
Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) with acrylamide copolymerized with gelatin (substrate-SDS-PAGE) was used to compare promastigote proteinases from two Leishmania species (L. braziliensis and L. major-like). Substrate-SDS-PAGE resolved at least 6 distinct proteinase activities with relative molecular masses between 20
