Ecotin-like serine peptidase inhibitor ISP1 of Leishmania major plays a role in flagellar pocket dynamics and promastigote differentiation [PDF]

, 2012
Leishmania ISPs are ecotin-like natural peptide inhibitors of trypsin-family serine peptidases, enzymes that are absent from the Leishmania genome. This led to the proposal that ISPs inhibit host serine peptidases and we have recently shown that ISP2 ...

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

Brazilian 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

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

Cytoskeleton, 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 ...

Heterogeneity of cysteine proteinases in Leishmania braziliensis and Leishmania major.

Brazilian 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

Charaterization of Leishmania major Friedlin Telomeric Terminus [PDF]

Memórias do Instituto Oswaldo Cruz, 2002
Here we have characterized Leishmania major (Friedlin) telomeric terminus (the very end) using recombinants obtained by a vector-adaptor cloning protocol. As in L. donovani, the last nine nucleotides of L. major terminus are 5'-GGTTAGGGT-OH 3', differing from Trypanosoma cruzi and T.

Isolation and molecular identification of cutaneous leishmaniasis in humans and dogs in middle Euphrates, Iraq [PDF]

Iraqi Journal of Veterinary Sciences
In Iraq, one of the endemic illnesses is cutaneous Leishmaniasis. This study aimed to characterize local isolates of Leishmania tropica and Leishmania major molecularly and determine how closely related they were to reference isolates from nearby nations.

The Geographical Distribution of Cutaneous Leishmaniasis Causative Agents in Iran and Its Neighboring Countries, A Review

Frontiers in Public Health, 2020
Leishmania tropica and Leishmania major are both the main cause of anthroponotic (ACL) and zoonotic cutaneous leishmaniasis (ZCL), respectively, in the Old World.

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

, 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 ...

ATG5 is essential for ATG8-dependent autophagy and mitochondrial homeostasis in Leishmania major [PDF]

, 2012
Macroautophagy has been shown to be important for the cellular remodelling required for Leishmania differentiation. We now demonstrate that L. major contains a functional ATG12-ATG5 conjugation system, which is required for ATG8-dependent autophagosome ...
