Biosynthesis of vitamins and cofactors in bacterium-harbouring trypanosomatids depends on the symbiotic association as revealed by genomic analyses. [PDF]

PLoS ONE, 2013
Some non-pathogenic trypanosomatids maintain a mutualistic relationship with a betaproteobacterium of the Alcaligenaceae family. Intensive nutritional exchanges have been reported between the two partners, indicating that these protozoa are excellent ...

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).

Polyamine Metabolism for Drug Intervention in Trypanosomatids

Pathogens
Neglected tropical diseases transmitted by trypanosomatids include three major human scourges that globally affect the world’s poorest people: African trypanosomiasis or sleeping sickness, American trypanosomiasis or Chagas disease and different types of

Peptides as a Therapeutic Alternative Against Leishmaniasis: A Scoping Review

Chemical Biology &Drug Design, Volume 107, Issue 5, May 2026.
This scoping review of 79 studies identified 231 antimicrobial peptides with anti‐Leishmania activity, including natural‐derived and synthetic peptides (inspired by natural sources or developed through rational design). Most were evaluated in vitro against promastigote and/or amastigote forms, with synthetic peptides showing a more promising effect ...

Comparative analysis of the mobilome yields new insights into its diversity, dynamics and evolution in parasites of the Trypanosomatidae family

Parasitology
Transposable elements (TEs) have the ability to move and amplify inside the host genome, making them a pivotal source of genome plasticity. Presently, only 4 TE clades (all classified as Class I retrotransposons) have been identified in trypanosomatids ...

Apoptosis in parasites and parasite-induced apoptosis in the host immune system: a new approach to parasitic diseases

Brazilian Journal of Medical and Biological Research, 1999
Apoptosis, a form of programmed cell death (PCD), has been described as essential for normal organogenesis and tissue development, as well as for the proper function of cell-renewal systems in adult organisms.

Glycosomal Phosphoenolpyruvate Carboxykinase CRISPR/Cas9‐Deletion and Its Role in Trypanosoma cruzi Metacyclogenesis and Infectivity in Mammalian Host

The FASEB Journal, Volume 40, Issue 6, 31 March 2026.
Effects of PEPCK deficiency in Trypanosoma cruzi bioenergetics and life stages. ABSTRACT Trypanosoma cruzi, the causative agent of Chagas disease, possesses glycosomes—unique organelles that house key metabolic enzymes, several of which are promising therapeutic targets.

Leptoconops nosopheris sp. n. (Diptera: Ceratopogonidae) and Paleotrypanosoma burmanicus gen. n., sp. n. (Kinetoplastida: Trypanosomatidae), a biting midge - trypanosome vector association from the Early Cretaceous

Memorias do Instituto Oswaldo Cruz, 2008
Leptoconops nosopheris sp. n. (Diptera: Ceratopogonidae) is described from a blood-filled female biting midge in Early Cretaceous Burmese amber. The new species is characterized by a very elongate terminal flagellomere, elongate cerci, and an indistinct ...

Repurposing of Inhibitors of Plasmodial Aspartate Transcarbamoylase Toward Trypanosoma Cruzi

ChemMedChem, Volume 21, Issue 6, 27 March 2026.
Aspartate transcarbamoylase (ATC) catalyzes the committed and rate‐limiting step in the pyrimidine de novo biosynthesis pathway. While previously suggested to be a potential target for antimalarial, antitubercular, and antioncologic drug discovery, we hypothesized that an existing compound library of ATC inhibitors designed from one scaffold by ...

Exploring Novel Nitrofuryl‐1,3,4‐Thiadiazole‐Based Derivatives: Design, Synthesis, and Evaluation of In Vitro Leishmanicidal and Trypanocidal Activity

Archiv der Pharmazie, Volume 359, Issue 3, March 2026.
In a series of substituted 1‐[5‐(5‐nitrofuran‐2‐yl)‐1,3,4‐thiadiazol‐2‐yl]piperidine‐4‐carboxamides evaluated for in vitro antileishmanial and antitrypanosomal activity, compound 18 emerged as the most promising derivative, showing submicromolar anti‐parasitic effects targeting diverse Leishmania and Trypanosoma species and acceptable selectivity ...
