Experimental transmission of Leishmania (Leishmania) amazonensis to immunosuppressed mice through the bite of Lutzomyia longipalpis (Diptera: Psychodidae) results in cutaneous leishmaniasis

Revista do Instituto de Medicina Tropical de São Paulo, 2021
Lutzomyia longipalpis is the natural vector of Leishmania (Leishmania) infantum, but it is also permissive for several Leishmania species that are related to cutaneous leishmaniasis (CL). Maranhao State (Northeast of Brazil) is endemic for CL and has the

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).

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 ...

Leishmania amazonensis: Characterization of an ecto-phosphatase activity [PDF]

Experimental Parasitology, 2006
We have characterized a phosphatase activity present on the external surface of Leishmania amazonensis, using intact living parasites. This enzyme hydrolyzes the substrate p-nitrophenylphosphate (p-NPP) at the rate of 25.70+/-1.17 nmol Pi x h(-1) x 10(-7)cells. The dependence on p-NPP concentration shows a normal Michaelis-Menten kinetics for this ecto-

Multifunctional Oregano‐Derived Plasma Polymer Coatings for Wound Healing Applications: An In Vitro Study

International Wound Journal, Volume 23, Issue 6, June 2026.
ABSTRACT Chronic wounds, exacerbated by infection, aging, diabetes, and oxidative stress, remain a significant challenge in clinical management and impose a substantial burden on healthcare systems. This study presents oregano‐derived plasma polymers (OPP) as a multifunctional surface coating for advanced wound healing applications.

Fusion between Leishmania amazonensis and Leishmania major parasitophorous vacuoles: live imaging of coinfected macrophages. [PDF]

PLoS Neglected Tropical Diseases, 2010
Protozoan parasites of the genus Leishmania alternate between flagellated, elongated extracellular promastigotes found in insect vectors, and round-shaped amastigotes enclosed in phagolysosome-like Parasitophorous Vacuoles (PVs) of infected mammalian ...
