Although local anesthetics (LA) are considered primarily Na+-channel blockers in the past decade, an alternative action of LA as inhibitors of fusion among compartments of the endocytic/exocytic pathways was described. In epimastigote forms of Trypanosoma cruzi, we observed that 50 mM dibucaine reduced the rates of uptake of bovine serum albumin (BSA) and immunoglobulin to 60% of control values in addition to the delay of exocytosis of cysteine proteases. Fusion among endocytic compartments was… 

Endocytosis and Exocytosis in Leishmania amazonensis Are Modulated by Bromoenol Lactone

The results suggested that the activity inhibited by BEL, which is one of the irreversible inhibitors of iPLA2, is required for both endocytosis and exocytotic in promastigotes of L. amazonensis.

Trypanosoma cruzi Peptidases: An Overview

The main T. cruzi peptidases are examined, focusing on their biological roles, especially concerning the parasite-mammalian host relations.

Synthesis and In Vitro Antibacterial Evaluation of Schiff Bases Derived FROM 2-Chloro-3-Quinolinecarboxaldehyde

Background: Design, identification, and synthesis of new antimicrobial agents along with preventive proceedings are essential to confront antibiotic-resistant pathogenic bacteria. Heterocyclic



Identification of a large pre-lysosomal compartment in the pathogenic protozoon Trypanosoma cruzi.

Immunocytochemical data from Lowicryl-embedded cells demonstrated that the reservosomes are acidic compartments with no acid phosphatase or typical lysosome-associated membrane proteins, but rich in cysteine proteinase, suggesting thatThe reservosome is a pre-lysosomal compartment.

Developmental and morphological regulation of clathrin-mediated endocytosis in Trypanosoma brucei.

Major endocytic coat proteins in T. brucei are described for the first time, andModulation of clathrin expression is likely to be an important factor in the developmental regulation of endocytosis and recycling in the African trypanosome.

Cysteine protease inhibitors alter Golgi complex ultrastructure and function in Trypanosoma cruzi.

It is suggested that cysteine protease inhibitors prevent the normal autocatalytic processing and trafficking of cruzain within the Golgi apparatus.

Endocytosis of gold-labeled proteins and LDL by Trypanosoma cruzi.

Although in amastigotes very few gold particles were seen bound to the cells, in trypomastigote they were observed bound toThe membrane that encloses the cell body, the flagellar pocket, and theFlagellum, suggesting that the receptors are more abundant in this form.

Receptor-mediated endocytosis in the bloodstream form of Trypanosoma brucei.

The uptake of various host plasma proteins by the bloodstream form of Trypanosoma brucei was studied both biochemically, using radiolabeled proteins, and with the electron microscope, using colloidal

Low temperature blocks fluid-phase pinocytosis and receptor-mediated endocytosis in Trypanosoma cruzi epimastigotes

The results suggest that low temperatures affect the transport and pinching of endocytic vesicles as well as the rate of delivery of transferrin to reservosomes.

Cysteine proteinase in Trypanosoma cruzi: immunocytochemical localization and involvement in parasite-host cell interaction.

A monospecific polyclonal antibody obtained against a cysteine proteinase isolated from epimastigotes of Trypanosoma cruzi was used for the immunocytochemical localization of the protein by electron

Endocytosis by African trypanosomes. II. Occurrence in different life-cycle stages and intracellular sorting.

Endocytosis of HRP, but not of protein-gold markers, occurred in procyclic (uncoated) forms of Trypanosoma brucei and T. congolense.
