Selective effects of Euterpe oleracea (açai) on Leishmania (Leishmania) amazonensis and Leishmania infantum

Biomedicine & Pharmacotherapy, 2018
Leishmania (Leishmania) amazonensis and Leishmania infantum (=Leishmania chagasi) are protozoa that cause American cutaneous and visceral leishmaniasis, respectively. These diseases show a high incidence in developing countries such as Brazil. The treatments used for leishmaniasis are still limited due to their high cost and toxicity.

The Regulatory Effect of Histone Deacetylase (HDAC) 1 and 2 on iNOS, IL‐6, TNF‐α and IL‐10 Expression in Canine Macrophages Infected With Leishmania infantum

Parasite Immunology, Volume 48, Issue 4, April 2026.
ABSTRACT Zoonotic visceral leishmaniasis is caused by Leishmania (Leishmania) infantum. Dogs are considered the most critical urban reservoirs of L. (L.) infantum due to their high infection rate and direct transmission to humans. The parasite has developed mechanisms to evade the host's defence system by inhibiting macrophage activation, thereby ...

Heparin modulates the endopeptidase activity of Leishmania mexicana cysteine protease cathepsin L-Like rCPB2.8

, 2013
Cysteine protease B is considered crucial for the survival and infectivity of the Leishmania in its human host. Several microorganism pathogens bind to the heparin-like glycosaminoglycans chains of proteoglycans at host-cell surface to promote their ...

Phytochemical and Biological Evaluation of Leaves, Stems, and Roots of Schinus weinmanniifolia Mart. Ex Engl.

Chemistry &Biodiversity, Volume 23, Issue 3, March 2026.
Ethanolic extracts from leaves, stems, and roots of Schinus weinmanniifolia Mart. ex Engl. were evaluated for phytochemical composition and biological activities. The extracts exhibited antioxidant, photoprotective, and antimicrobial activity, without hemolytic effects or cytotoxicity at active concentrations. Syringic acid, epicatechin, and rutin were

Evolutionary divergence and functional insights into the heteromeric cis‐prenyltransferase of Paramecium tetraurelia

The FEBS Journal, Volume 293, Issue 6, Page 1681-1707, March 2026.
Heteromeric cis‐prenyltransferases (CPT) are indispensable for dolichol synthesis and protein N‐glycosylation in most eukaryotes. The catalytic subunits are strongly conserved throughout evolution, in contrast to the evolutionarily variable accessory subunits. The POC1 protein from Paramecium tetraurelia is the smallest identified CPT‐accessory subunit

Developing giant plasma membrane vesicles from Leishmania cells to investigate the role of membrane proteins in photodynamic inactivation

Photochemistry and Photobiology, Volume 102, Issue 2, Page 480-488, March/April 2026.
In this study, we developed giant plasma membrane vesicles (GPMVs) from Leishmania amazonensis promastigote membranes to investigate the role of protein‐embedded membranes in methylene blue (MB) photooxidation. Upon MB photoactivation in model lipid membranes (giant unilamellar vesicles, GUVs), a distinct photooxidation effect was observed, marked by ...
