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

Journal 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.

Mitochondrial Dysfunction Induced by a Novel Salicylate‐Based 1,2,3‐Triazole Salt With Potent Antileishmanial Activity

Chemical Biology &Drug Design, Volume 106, Issue 6, December 2025.
A novel salicylate‐based 1,2,3‐triazole salt was synthesized and demonstrated potent and selective activity against Leishmania amazonensis. The most active compound induced mitochondrial dysfunction without hemolytic effects. In silico analyses also suggested favorable pharmacokinetic properties and oral bioavailability.

Natural Leishmania (Viannia) infections of phlebotomines (Diptera: Psychodidae) indicate classical and alternative transmission cycles of American cutaneous leishmaniasis in the Guiana Shield, Brazil

Parasite, 2017
From 1996 to 1999 multi-trapping methods (Center of Diseases Control, CDC) light traps, light-baited Shannon traps, and aspiration on tree bases) were used to study the phlebotomine fauna of the “Serra do Navio” region of the Brazilian State of Amapá ...

Colonisation resistance in the sand fly gut:Leishmania protects Lutzomyia longipalpis from bacterial infection [PDF]

, 2014
BACKGROUND: Phlebotomine sand flies transmit the haemoflagellate Leishmania, the causative agent of human leishmaniasis. The Leishmania promastigotes are confined to the gut lumen and are exposed to the gut microbiota within female sand flies.

Quantitative phenetics and taxonomy of some phlebotomine taxa [PDF]

Memórias do Instituto Oswaldo Cruz, 1999
Elucidating the evolution of Phlebotominae is important not only to revise their taxonomy, but also to help understand the origin of the genus Leishmania and its relationship with humans. Our study is a phenetic portrayal of this history based on the genetic relationships among some New Word and Old Word taxa.

Establishment and characterization of a new continuous cell line from Lutzomyia longipalpis (Diptera: Psychodidae) and its susceptibility to infections with arboviruses and Leishmania chagasi

Memorias do Instituto Oswaldo Cruz, 2000
Embryonic tissue explants of the sand fly Lutzomyia longipalpis (Lutz & Neiva 1912) the main vector of Leishmania chagasi (Cunha and Chagas), were used to obtain a continuous cell line (Lulo).

[Phlebotomine sandflies of Southern Brazil].

Revista de saude publica, 2005
OBJECTIVE: To identify the sandfly fauna and some aspects of their behavior in forest and anthropic environments. METHODS: Sandfly captures were undertaken in farm (23º 6' S; 50º 22' W), in Southern Brazil. Falcão light traps were set in forest, domicile and domestic animal shelters and mosquitoes were collected monthly, between 17h and 7h, from March ...
