Potential vectors of Leishmaniases in the Environmental Protection Area and Tinguá Federal Biological Reserve, Municipality of Nova Iguaçu, Rio de Janeiro, Brazil

Medical and Veterinary Entomology, Volume 40, Issue 2, Page 246-259, June 2026.
This study was to describe the composition of sand fly fauna, detect potential vectors of Leishmania spp. in the Tinguá district, an ATL endemic, Rio de Janeiro, Brazil. Seven species of vectorial importance in the epidemiological cycle of leishmaniasis was observed: Nyssomyia intermedia, Migonemyia migonei, Pintomyia fischeri, Psychodopygus hirsutus ...

Efficacy of a diarylheptanoid derivative against Leishmania amazonensis [PDF]

Memórias do Instituto Oswaldo Cruz, 2003
The activity of several diarylheptanoid derivatives (curcuminoids) was previously evaluated against Leishmania amazonensis promastigotes and among them the most active compound was the [1-(4-methoxy-phenyl)-7-(3,4-methoxy-4-hydroxy-phenyl)-1,6-heptadien-3, 5-dione]. This derivative was chosen to be assayed in vivo in a treatment trial.

Real-time imaging of Leishmania mexicana-infected early phagosomes: a study using primary macrophages generated from green fluorescent protein-Rab5 transgenic mice

, 2009
The small GTPase Rab5 is a key regulator of endosome/phagosome maturation and in intravesicular infections marks a phagosome stage at which decisions over pathogen replication or destruction are integrated.

Canine Leishmaniasis in Rio de Janeiro, Brazil (2000–2015): Taxonomic Characterisation of Etiological Agents and Geospatial Case Analysis

Zoonoses and Public Health, Volume 73, Issue 4, Page 314-325, June 2026.
ABSTRACT Introduction Canine Leishmaniasis is a vector‐borne zoonotic disease caused by several species of protozoa of the genus Leishmania. In the state of Rio de Janeiro (RJ), Leishmania braziliensis is the most prevalent species causing tegumentary leishmaniasis (TL) and Leishmania infantum is the main causative agent of visceral leishmaniasis (VL).

DC-SIGN Mediates the Interaction Between Neutrophils and Leishmania amazonensis-Infected Dendritic Cells to Promote DC Maturation and Parasite Elimination

Frontiers in Immunology, 2021
BackgroundLeishmaniasis is a neglected arthropod-borne disease that affects millions of people worldwide. Successful Leishmania infections require the mitigation of immune cell functions leading to parasite survival and proliferation.

Visceral leishmaniasis caused by Leishmania (Leishmania) amazonensis associated with Hodgkin’s lymphoma

Revista do Instituto de Medicina Tropical de São Paulo, 2022
Visceral leishmaniasis (VL) is mainly caused by Leishmania (Leishmania) donovani and Leishmania (L.) infantum; however, other Leishmania species have been associated with VL. We report a case of a patient simultaneously diagnosed with VL caused by Leishmania (L.) amazonensis and Hodgkin's lymphoma.

Structural basis of secreted acid phosphatase polymerization in the Leishmania parasite

Protein Science, Volume 35, Issue 5, May 2026.
Abstract Enzymes that assemble into filaments typically transition between protomeric and polymeric states in response to cellular conditions. In contrast, the secreted acid phosphatase (SAP) of Leishmania, one of the most abundant extracellular glycoproteins produced by the parasite and regarded as a major virulence factor in the neglected tropical ...

Cinnamides Target Leishmania amazonensis Arginase Selectively [PDF]

Molecules, 2020
Caffeic acid and related natural compounds were previously described as Leishmania amazonensis arginase (L-ARG) inhibitors, and against the whole parasite in vitro. In this study, we tested cinnamides that were previously synthesized to target human arginase.
