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

open access: yesThe 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.

The P2X7 Receptor and Its Relation to Neglected Tropical Diseases: Focusing on Chagas Disease

open access: yesJournal of Tropical Medicine, Volume 2026, Issue 1, 2026.
Chagas disease, caused by Trypanosoma cruzi, is a neglected tropical disease (NTD) that can lead to severe cardiac complications, including chronic Chagas cardiomyopathy. While NTDs are caused by a variety of pathogens—such as protozoa, bacteria, viruses, and helminths, Chagas disease remains underexplored, particularly regarding host immune responses.

Oxidative Stress Modulation and Antileishmanial Activity of Salvinia auriculata

open access: yesChemistry &Biodiversity, Volume 22, Issue 12, December 2025.
Ethanolic extract of Salvinia auriculata showed significant antioxidant and antileishmanial activities. Salviniside II, the major metabolite, was isolated, structurally characterized, and evaluated, but exhibited weaker antiparasitic effects when compared to the whole extract.

DPPH‐based Antioxidant Screening and Cellulase‐assisted Hydrodistillation of Matourea azurea: Improved Essential Oil Yield and Density Functional Theory Insights Into a Rare Terpene

open access: yesChemistry &Biodiversity, Volume 22, Issue 12, December 2025.
ABSTRACT Essential oils are rich in bioactive molecules like terpenes and phenolic compounds, but have low yields, making process efficiency crucial. Enzyme‐assisted hydrodistillation is a sustainable alternative, enhancing oil release by degrading the cell wall.

Fungal Biodiversity From the Atlantic Forest With Bioactive Metabolites Against Cutaneous Leishmaniasis

open access: yesChemistry &Biodiversity, Volume 22, Issue 12, December 2025.
ABSTRACT Biodiversity offers a rich source of bioactive compounds for drug discovery. We isolated Aspergillus fumigatus from compost in the Atlantic Forest and found its extract active against Leishmania (Leishmania) amazonensis. Two crude extracts, I06 and I75, were selected for further study.
