Comparative study of the ability of Leishmania mexicana promastigotes and amastigotes to alter macrophage signalling and functions

, 2010
Leishmania alternates between two morphologically different stages: promastigotes and amastigotes. While the majority of reports focused on how the promastigote form can alter macrophage signalling and function, fewer reports investigated signalling ...

Cell migration induced by Leishmania (Leishmania) amazonensis, Leishmania (Leishmania) major and Leishmania (Viannia) braziliensis into the peritoneal cavity of BALB/c mice

Journal of Venomous Animals and Toxins including Tropical Diseases, 2010
In American cutaneous leishmaniasis, the initial infection phase is characterized by recruitment of neutrophils and monocytes. The migration of these cells in response to the presence of Leishmania in the peritoneum of affected animals remains unclear ...

Impacto del volumen del fagosoma en los niveles de ARNm de IL-12 en infección por Leishmania amazonensis [PDF]

, 2015
La interacción entre macrófago y patógeno es la responsable de modular la respuesta adaptativa mediada por linfocitos T como células efectoras. En la infección por Leishmania se ha establecido una clara relación entre la secreción de citoquinas pro ...

Comparative two-dimensional gel electrophoresis maps for promastigotes of Leishmania amazonensis and Leishmania major

Brazilian Journal of Infectious Diseases
The outcome of Leishmania infections is determined by both the parasite species and the host genetic makeup. While much has been learned regarding immune responses to this parasite, our knowledge on parasite-derived factors is limited.

CENTRAL NERVOUS SYSTEM INVOLVEMENT IN EXPERIMENTAL INFECTION WITH LEISHMANIA (LEISHMANIA) AMAZONENSIS

The American Journal of Tropical Medicine and Hygiene, 2003
We describe the pathologic alterations of the central nervous system (CNS) observed in experimental tegumentary leishmaniasis in BALB/c and Swiss mice. The mice were subcutaneously infected with 104 amastigotes of Leishmania (Leishmania) amazonensis. Animals were killed and brains were removed for histologic and immunocytochemical studies.

Immunogold labeling and cerium cytochemistry of the enzyme ecto-5'-nucleotidase in promastigote forms of Leishmania species

Memorias do Instituto Oswaldo Cruz, 1993
We have applied both enzyme cytochemistry and immunological labeling techniques to characterize the enzyme 5'-nucleotidase (5'-Nase), at the ultrastructural level, in promastigote forms of four Leishmania species: Leishmania amazonensis, Leishmania ...

Verbascoside Inhibits Promastigote Growth and Arginase Activity of Leishmania amazonensis [PDF]

, 2016
Verbascoside (1) is a phenylethanoid glycoside that has antileishmanial activity against Leishmania infantum and Leishmania donovani. In this study, we verified the activity of 1 on Leishmania amazonensis and arginase inhibition.
