Proteomic Mapping of Multifunctional Complexes Within Triatomine Saliva [PDF]

Frontiers in Cellular and Infection Microbiology, 2020
Triatomines are hematophagous insects that transmit Trypanosoma cruzi, the etiological agent of Chagas disease. This neglected tropical disease represents a global health issue as it is spreading worldwide. The saliva of Triatominae contains miscellaneous proteins crucial for blood feeding acquisition, counteracting host's hemostasis while performing ...

Effect of blood components, abdominal distension, and ecdysone therapy on the ultrastructural organization of posterior midgut epithelial cells and perimicrovillar membranes in Rhodnius prolixus

Memorias do Instituto Oswaldo Cruz, 2004
The effects of blood components, nerve-cord severance, and ecdysone therapy on the posterior midgut epithelial cells of 5th-instar Rhodnius prolixus nymphs 10 days after feeding were analyzed by transmission electron microscopy. Cutting the nerve-cord of

DmCatD, a cathepsin D-like peptidase of the hematophagous insect Dipetalogaster maxima (Hemiptera: Reduviidae): Purification, bioinformatic analyses and the significance of its interaction with lipophorin in the internalization by developing oocytes [PDF]

, 2018
DmCatD, a cathepsin D-like peptidase of the hematophagous insect Dipetalogaster maxima, is synthesized by the fat body and the ovary and functions as yolk protein precursor. Functionally, DmCatD is involved in vitellin proteolysis.

Expression of Fluorescent Genes in Trypanosoma cruzi and Trypanosoma rangeli (Kinetoplastida: Trypanosomatidae): Its Application to Parasite-Vector Biology [PDF]

, 2005
Two Trypanosoma cruzi-derived cloning vectors, pTREX-n and pBs:CalB1/CUB01, were used to drive the expression of green fluorescent protein (GFP) and DsRed in Trypanosoma rangeli Tejera, 1920, and Trypanosoma cruzi Chagas, 1909, isolates, respectively ...

Scalable Access to N‑Acylindole Linkages: Enabling the Synthesis of Antitrypanosomal Noncanonical Cyclic Peptides for Chagas Disease

Angewandte Chemie, Volume 138, Issue 15, 6 April 2026.
A gram‐scale supply of bulbiferamide A, which features a rare N‐acylindole linkage and possesses potent inhibitory activity against Trypanosoma cruzi epimastigotes (IC50 = 4.1 µM)—the causative parasite of Chagas disease—was successfully achieved. Moreover, the cyclization strategy developed in this study facilitated the synthesis of noncanonical ...

Molecular epidemiology of domestic and sylvatic Trypanosoma cruzi infection in rural northwestern Argentina [PDF]

, 2008
Genetic diversity of Trypanosoma cruzi populations and parasite transmission dynamics have been well documented throughout the Americas, but few studies have been conducted in the Gran Chaco ecoregion, one of the most highly endemic areas for Chagas ...

'It is like a tomato stall where someone can pick what he likes': structure and practices of female sex work in Kampala, Uganda. [PDF]

, 2013
BACKGROUND: Effective interventions among female sex workers require a thorough knowledge of the context of local sex industries. We explore the organisation of female sex work in a low socio-economic setting in Kampala, Uganda.

Rapid detection of human blood in triatomines (kissing bugs) utilizing a lateral flow immunochromatographic assay - A pilot study

Memorias do Instituto Oswaldo Cruz
BACKGROUND DNA- and proteomics-based techniques are currently used to identify a triatomine human blood meal. These methods are time consuming, require access to laboratories with sophisticated equipment, and trained personnel.
