In Vitro and In Vivo Activity of a Palladacycle Complex on Leishmania (Leishmania) amazonensis

PLoS Neglected Tropical Diseases, 2012
Antitumor cyclopalladated complexes with low toxicity to laboratory animals have shown leishmanicidal effect. These findings stimulated us to test the leishmanicidal property of one palladacycle compound called DPPE 1.2 on Leishmania (Leishmania) amazonensis, an agent of simple and diffuse forms of cutaneous leishmaniasis in the Amazon region, Brazil ...

Effects of Brazilian propolis on Leishmania amazonensis [PDF]

Memórias do Instituto Oswaldo Cruz, 2007
Leishmaniasis, an endemic parasitosis that leads to chronic cutaneous, mucocutaneous or visceral lesions, is part of those diseases, which still requires improved control tools. Propolis has shown activities against different bacteria, fungi, and parasites.

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 ...

In vitro leishmanicidal effect of Yangambin and Epi-yangambin lignans isolated from Ocotea fasciculata (Nees) Mez

Frontiers in Cellular and Infection Microbiology, 2023
IntroductionYangambin and epi-yangambin are the main lignans found in Louro-de-Cheiro [Ocotea fasciculata (Nees) Mez], a tree native to the Atlantic forests of northeastern Brazil whose leaves and bark are widely used in folk medicine.

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 ...

Leishmania amazonensis promastigotes in 3D Collagen I culture: an in vitro physiological environment for the study of extracellular matrix and host cell interactions [PDF]

PeerJ, 2014
Leishmania amazonensis is the causative agent of American cutaneous leishmaniasis, an important neglected tropical disease. Once Leishmania amazonensis is inoculated into the human host, promastigotes are exposed to the extracellular matrix (ECM) of the ...

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 ...

Immune responses induced by a Leishmania (Leishmania) amazonensis recombinant antigen in mice and lymphocytes from vaccinated subjects

Revista do Instituto de Medicina Tropical de São Paulo, 1997
In the search for Leishmania recombinant antigens that can be used as a vaccine against American Cutaneous Leishmaniasis, we identified a Leishmania (Leishmania) amazonensis recombinant protein of 33 kD (Larp33) which is recognized by antibodies and ...

Murine T Cell‐Dependent Response Affects Leishmania amazonensis Amastigote Survival and Virulence

Cell Biology International, Volume 50, Issue 8, August 2026.
ABSTRACT Our group has previously described the infection course of Leishmania amazonensis in BALB/c and BALB/cnu/nu mice, which have distinct T‐cell dependent responses. In this study, lesion‐derived amastigotes exhibited differential protein expression in a host‐dependent manner.
