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

open access: yesJournal 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.

Bidirectional Regulation of NLRP3 Inflammasome and Mitochondrial Quality Control in Sepsis: Mechanisms and Therapeutic Implications

open access: yesMediators of Inflammation, Volume 2026, Issue 1, 2026.
Characterized by its capacity to induce organ failure, sepsis constitutes a life‐threatening pathological state with high incidence and mortality rates. Current treatments primarily focus on antimicrobial therapy and organ support, lacking direct interventions targeting the restoration of cellular or organelle function.

An Assay for the Seeding of Homotypic Pyrin Domain Filament Transitions

2022
Pattern recognition receptors of innate immune cells allow the recognition of invariant microbial structures. The nucleotide-binding oligomerization domain-like receptors (NLRs) comprise 22 members, divided into 3 subfamilies. Homotypic pyrin domain (PYD) interactions were shown to mediate the interaction of inflammasome forming NLRPs with the adaptor ...

Pyrin N-Terminal Homology Domain- and Caspase Recruitment Domain-Dependent Oligomerization of ASC

Biochemical and Biophysical Research Communications, 2001
ASC was first identified as a caspase recruitment domain (CARD)-containing proapoptotic molecule that forms insoluble aggregates during apoptosis. Here, we report both the pyrin N-terminal homology domain (PYD) and CARD domains are involved in the aggregation of ASC.

Structural and Functional Analysis of Mutated Human Pyrin B30.2 Domain

Current Proteomics, 2020
Background: Familial Mediterranean Fever (FMF) is a prototypical hereditary autoinflammatory disease affecting principally Mediterranean populations and characterized by recurrent frequent fever and inflammation. The disease is essentially caused by inherited mutations in the MEFV gene which encodes pyrin protein.
