Colonisation resistance in the sand fly gut: Leishmania protects Lutzomyia longipalpis from bacterial infection [PDF]

open access: yesParasites & Vectors, 2014
Background Phlebotomine sand flies transmit the haemoflagellate Leishmania, the causative agent of human leishmaniasis. The Leishmania promastigotes are confined to the gut lumen and are exposed to the gut microbiota within female sand flies.

Human Dendritic Cell Maturation Is Modulated by Leishmania mexicana through Akt Signaling Pathway [PDF]

open access: yesTropical Medicine and Infectious Disease
Dendritic cells (DC) along with macrophages are the main host cells of the intracellular parasite Leishmania. DC traverse a process of maturation, passing through an immature state with phagocytic ability to a mature one where they can modulate the ...

Endocytosis and Sphingolipid Scavenging in Leishmania mexicana Amastigotes [PDF]

open access: yesBiochemistry Research International, 2012
Leishmania species are the causative agents of the leishmaniases, a spectrum of neglected tropical diseases. Amastigote stage parasites exist within macrophages and scavenge host factors for survival, for example, Leishmania species utilise host ...

The DNA polymerases ofLeishmania mexicana [PDF]

open access: yesFEMS Microbiology Letters, 1992
Two previously isolated DNA polymerases from the parasitic protozoan Leishmania mexicana were further characterized by exposure to inhibitors of mammalian DNA polymerases. DNA polymerase A, a high molecular mass enzyme, and DNA polymerase B, a beta-like DNA polymerase were compared to each other and to their mammalian counterparts regarding pH optimum,
