Mechanisms of Immune Evasion, Dissemination, and Persistence in Leishmania amazonensis Infection

Parasite Immunology, Volume 48, Issue 1, January 2026.
ABSTRACT Leishmania amazonensis is one of the etiological agents of cutaneous leishmaniasis in its localised form. Moreover, this parasite can cause more severe disease conditions, such as diffuse and disseminated cutaneous leishmaniasis. The development of more severe clinical manifestations is associated with the parasite's ability to establish a ...

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.
