Impact of Leishmania mexicana infection on dendritic cell signaling and functions. [PDF]

PLoS Neglected Tropical Diseases, 2014
Leishmania parasites have the ability to modify macrophage signaling pathways in order to survive and multiply within its mammalian host. They are also known to invade other cells including neutrophils, fibroblasts and dendritic cells (DCs).

BALB/c mice deficient in CD4(+) T cell IL-4R alpha expression control Leishmania mexicana load although female but not male mice develop a healer phenotype [PDF]

, 2011
Immunologically intact BALB/c mice infected with Leishmania mexicana develop non-healing progressively growing lesions associated with a biased Th2 response while similarly infected IL-4R alpha-deficient mice fail to develop lesions and develop a robust ...

Identification of semicarbazones, thiosemicarbazones and triazine nitriles as inhibitors of Leishmania mexicana cysteine protease CPB [PDF]

, 2013
Cysteine proteases of the papain superfamily are present in nearly all eukaryotes. They play pivotal roles in the biology of parasites and inhibition of cysteine proteases is emerging as an important strategy to combat parasitic diseases such as sleeping

Leishmania chitinase facilitates colonization of sand fly vectors and enhances transmission to mice [PDF]

, 2008
Chitinases of trypanosomatid parasites have been proposed to fulfil various roles in their blood-feeding arthropod vectors but so far none have been directly tested using a molecular approach.

Molecular typing reveals the co-existence of two transmission cycles of American cutaneous leishmaniasis in the Andean Region of Venezuela with Lutzomyia migonei as the vector

Memorias do Instituto Oswaldo Cruz, 2018
BACKGROUND The transmission routes for American cutaneous leishmaniasis (ACL) are in flux, so studies examining its transmission in humans, mammalian hosts, and sand fly vectors are urgently needed.
