Cervical carcinoma induces NLRP3 inflammasome activation and IL-1ß release in human peripheral blood monocytes affecting patients' overall survival.

Purpose: Our group previously demonstrated that genetic variants in inflammasome genes contribute to protection against the establishment of human papilloma virus (HPV)-associated cervical carcinoma (CC). The objective of this study was to better understand the contribution of inflammasome and its cytokines in the CC microenvironment.

Methods: The inflammasome activation was analyzed in CC tumoral cell lines and healthy donors (HD)' monocytes in co-culture.

Severe COVID-19 patients show a dysregulation of the NLRP3 inflammasome in circulating neutrophils.

SARS-CoV-2 triggers inflammasome-dependent release of pro-inflammatory cytokine IL-1β and pyroptosis, therefore, contributes to the huge inflammatory response observed in severe COVID-19 patients. Less is known about the engagement of inflammasome in neutrophils, main players in tissue injury and severe infection. We studied the activation of the inflammasome in neutrophils from severe COVID-19 patients and assessed its consequence in term of cells contribution to disease pathogenesis.

A common variant close to the "tripwire" linker region of NLRP1 contributes to severe COVID-19.

Objective And Design: The heterogeneity of response to SARS-CoV-2 infection is directly linked to the individual genetic background. Genetic variants of inflammasome-related genes have been pointed as risk factors for several inflammatory sterile and infectious disease. In the group of inflammasome receptors, NLRP1 stands out as a good novel candidate as severity factor for COVID-19 disease.

In-vitro NLRP3 functional test assists the diagnosis of cryopyrin-associated periodic syndrome (CAPS) patients: A Brazilian cooperation.

Objective: To report our five-years experience on the use of NLRP3 inflammasome functional assays in the differential diagnosis of Brazilian patients with a clinical suspicion of CAPS.

Patients And Methods: The study included 9 patients belonging to 2 families (I, II) and 7 unrelated patients with a clinical suspicion of AID according to Eurofever/PRINTO classification, recruited between 2017 and 2022. The control group for the NLRP3 functional assay consisted of 10 healthy donors and for the CBA cytokines measurement of 19 healthy controls.

Double-edged sword of inflammasome genetics in colorectal cancer prognosis.

Inflammation is a colorectal cancer (CRC) hallmark. Inflammasome-dependent cytokines IL-1ß and IL-18 can play a beneficial or detrimental role in tumorigenesis depending on cancer type. Variants in inflammasome genes were associated with tumor development and/or outcome, and have been proposed as potential biomarkers for population screening.
