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. In vitro results were then compared to CC patients' public databases.

Results: CC cells did not produce IL-1ß or IL-18 themselves, however, when in co-culture with HD monocytes, induced IL-1ß release in those leucocytes. Inflammasome activation appears to be partially dependent on the NLRP3 receptor. Public data analysis revealed that IL1B expression is increased in the CC compared to normal uterine cervix, and that patients with high IL1B expression had a shorter overall survival.

Conclusion: CC microenvironment can activate the inflammasome and IL-1ß release in surrounding monocytes, which could be detrimental for CC prognosis.

Ethnopharmacological Relevance: Mangifera indica (family Anacardiaceae), often acknowledged as mango and renowned for being a plant of diverse ethnopharmacological background since ancient times, harbors the polyphenolic bioactive constituent, mangiferin (MNG). MNG is a major phytochemical of Mangifera indica and other plants with a wide range of reported pharmacological activities, including antioxidant, anti-inflammatory, neuroprotective and hepatoprotective effects. MNG has also been utilized in traditional medicine; it is reportedly a major bioactive element in over 40 polyherbal products in traditional Chinese medicine (TCM), and two prominent anti-inflammatory, immunomodulatory and antiviral Cuban formulations.

Background: The spleen, as the body's largest peripheral immune organ and a crucial source of circulating monocytes, plays a significant role in the acute inflammatory response of spleen-derived macrophages to diseases. Therefore, studying the impact and mechanism of X-ray irradiation on spleen-derived macrophages' inflammatory responses is of great importance.

Method: Extracted and identified mice splenic macrophages were divided into four groups: control group, LPS and ATP co-stimulated non-irradiated group, LPS and ATP co-stimulated group irradiated after 6h, and LPS and ATP co-stimulated group irradiated after 12h.

Diabetes is associated with excessive inflammation, which negatively impacts the fracture healing process and delays bone repair. Previously, growing evidence indicated that activation of the nod-like receptor (NLR) family, such as nod-like receptor thermal protein domain-associated protein 3 (NLRP3) inflammasome induces a vicious cycle of chronic low-grade inflammatory responses in diabetic fracture. Here, we describe the synthesis of a bone adhesive hydrogel that can be locally injected into the fracture site and releases a natural inhibitor of NLRP3 (rutin) in response to pathological cue reactive oxygen species activity (ROS).

Fibrosis is the main pathological feature of aortic stiffness, which is a common extracardiac comorbidity of heart failure with preserved ejection fraction (HFpEF) and a contributor to left ventricular (LV) diastolic dysfunction. Systemic low-grade inflammation plays a crucial role in the pathogenesis of HFpEF and the development of vascular fibrosis. In this study, we investigate the inflammatory mechanism of aortic fibrosis in HFpEF using a novel mouse model.
