Structural Insights Into the Function of Leishmania major Adenylosuccinate Lyase. [PDF]
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 ...

T helper1/T helper2 cells and resistance/susceptibility to Leishmania infection : is this paradigm still relevant? [PDF]
Work in large part on Leishmania major in the 1980s identified two distinct apparently counter-regulatory CD4 T cell populations, T helper (h)1 and Th2, that controlled resistance/susceptibility to infection respectively.

Investigating the role of the Leishmania (Leishmania) major HASP and SHERP genes during metacyclogenesis in the sand fly vectors, Phlebotomus (Phlebotomus) papatasi and Ph. (Ph.) duboscqi [PDF]
Leishmania parasites are the causative agents of a diverse spectrum of infectious diseases termed the leishmaniases. These digenetic parasites exist as intracellular, aflagellate amastigotes in a mammalian host and as extracellular flagellated ...

The role of surface glycoconjugates in Leishmania midgut attachment examined by competitive binding assays and experimental development in sand flies [PDF]
SUMMARY Binding of promastigotes to the sand fly midgut epithelium is regarded as an essential part of the Leishmania life cycle in the vector. Among Leishmania surface molecules putatively involved in attachment to the sand fly midgut, two GPI-anchored ...

The SNARE protein family of Leishmania major [PDF]
Abstract Background Leishmania major is a protozoan parasite with a highly polarised cell shape that depends upon endocytosis and exocytosis from a single area of the plasma membrane, the flagellar pocket.

Increased transmission potential of Leishmania major/Leishmania infantum hybrids [PDF]
Development of Leishmania infantum/Leishmania major hybrids was studied in two sand fly species. In Phlebotomus papatasi, which supported development of L. major but not L. infantum, the hybrids produced heavy late-stage infections with high numbers of metacyclic promastigotes.

Plasmenylethanolamine synthesis in Leishmania major [PDF]
SummaryEthanolamine glycerophospholipids are ubiquitous cell membrane components. Trypanosomatid parasites of the genus Leishmania synthesize the majority of their ethanolamine glycerophospholipids as 1‐O‐alk‐1′‐enyl‐2‐acyl‐sn‐glycero‐3‐phosphoethanolamine or plasmenylethanolamine (PME) through the Kennedy pathway.

L-arginine deprivation impairs Leishmania major-specific T-cell responses. [PDF]
The amino acid L-arginine plays a crucial role in the regulation of immune responses. We have recently shown that uncontrolled replication of Leishmania parasites at the site of pathology correlates with high levels of arginase activity in nonhealing ...

The LPG1 gene family of Leishmania major [PDF]
In Leishmania major, the core of the abundant surface lipophosphoglycan (LPG) is structurally related to that of the smaller glycosylinositolphospholipids (GIPLs) in containing galactosylfuranose (Gal(f)) residues in a Gal(f) (beta1, 3)Man motif. However, deletion of the putative Gal(f)-transferase (Gal(f)T) LPG1 affected Gal(f) incorporation in LPG ...

Leishmania major chromosome 3 contains two long convergent polycistronic gene clusters separated by a tRNA gene [PDF]
Leishmania parasites (order Kinetoplastida, family Trypanosomatidae) cause a spectrum of human diseases ranging from asymptomatic to lethal. The approximately 33.6 Mb genome is distributed among 36 chromosome pairs that range in size from approximately 0.
