Persistence of Leishmania antigen in C57Bl/6j inbred mice infected with Leishmania (Leishmania) amazonensis [PDF]

Revista da Associação Médica Brasileira, 1999
To develop an animal model for studying mucocutaneous leishmaniasis.The hind footpad of C57Bl/6j inbred mice was experimentally infected with 10(7) Leishmania (Leishmania) amazonensis promastigote and the skin was studied through light and electron transmission microscopy and immunohistochemistry (PAP) techniques.There were morphological evidences of ...

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 ...

Cohabitation of Leishmania amazonensis and Coxiella burnetii [PDF]

Trends in Microbiology, 1996
Intracellular pathogens customize the composition and function of the vacuoles they occupy, and can arrest or distort vacuolar maturation. In doubly infected cells, vacuoles that contain two different parasites can be used to test for exclusionary mechanisms, for expression of vacuolar phenotypes that permit or restrict fusion, and for the survival of ...

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

, 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).
