The NLRP3 Inflammasome as a Central Driver of Mastitis Pathogenesis: A Review
AI summary Read the abstract
This review pulls together recent research on udder infections (mastitis) in dairy cows, finding that many different triggers—including bacteria, heat stress, and even nanoplastics—seem to activate the same internal "alarm system" in cells that drives inflammation and damage. This matters because it points scientists toward treatments like selenium, probiotics, and plant compounds that could fight mastitis without antibiotics, though most evidence so far comes from lab and mouse studies rather than actual dairy cattle. The nanoplastics angle is also a reminder that these tiny plastic particles—found throughout our environment—may trigger infl
Mastitis remains the most economically damaging disease of dairy production, and recent molecular work has converged on the NLRP3 inflammasome as a key integrative node of its pathogenesis. This narrative review integrates evidence published largely between 2015 and 2026 to show how diverse triggers—Staphylococcus aureus and Escherichia coli, lipopolysaccharide (LPS) and lipoteichoic acid (LTA), non-esterified fatty acids (NEFA), heat stress, environmental xenobiotics including nanoplastics, and microbiota-derived signals—may funnel into a common NLRP3–ASC–caspase-1–GSDMD axis that drives pyroptosis, blood–milk barrier disruption, and clinical disease. The review examines the potential obligatory role of reactive oxygen species (ROS), mitochondrial dysfunction, and selenoprotein-mediated redox control in licensing inflammasome assembly. It further evaluates the emerging gut–mammary and rumen–mammary axes that operate upstream of local epithelial activation. We survey a structurally diverse therapeutic landscape encompassing dietary selenium, probiotics, microbial metabolites, plant-derived nanovesicles, polyphenols, ginsenosides, and small-molecule NLRP3 antagonists, identifying recurring mechanistic motifs that suggest combinatorial regimens may yield additive benefit. Importantly, much of the evidence derives from in vitro and murine models, and we highlight the translational gaps that must be bridged before clinical application in dairy cattle. Finally, we map outstanding research gaps and propose priorities for translational work aimed at sustainable, antibiotic-sparing management of bovine mastitis.

NLRP3 inflammasome as a sensor of micro- and nanoplastics immunotoxicity
AI summary Read the abstract
This review examines how micro and nanoplastics may trigger the NLRP3 inflammasome, a key part of the human immune system that activates inflammatory responses when it detects harmful particles. Evidence suggests that plastic particles can penetrate tissue barriers and set off inflammation cascades similar to those caused by other known toxic particulates. Understanding this immune pathway is important for assessing the potential health effects of microplastic exposure in people.
Assessing the NLRP3 Inflammasome Activating Potential of a Large Panel of Micro- and Nanoplastics in THP-1 Cells
AI summary Read the abstract
Researchers developed an in vitro screening system using immune cells to assess whether various micro- and nanoplastics can activate the NLRP3 inflammasome, a key component of the innate immune system involved in inflammatory responses. The study tested a large panel of plastic particles of different sizes, shapes, and polymer types, providing insights into which characteristics may trigger inflammatory responses.

This review examined how micro- and nano-plastics trigger inflammatory responses through interactions with immune cells, finding that particles activate multiple signaling pathways including NF-kB and NLRP3 inflammasome, potentially contributing to chronic low-grade inflammation linked to cardiovascular disease, autoimmune disorders, and cancer.
NLRP3 inflammasome activation by particles and fibers: implications for human hazard assessment
AI summary Read the abstract
When your body encounters tiny particles—like asbestos, quartz dust, or even microplastics—it can trigger an internal "alarm system" (called the NLRP3 inflammasome) that causes inflammation, which over time may contribute to disease. This review pulls together decades of research showing this link is well-proven for workplace dusts, but says scientists still don't fully know how risky everyday exposure to things like microplastics or air pollution really is. The authors argue that testing new materials for this inflammation trigger should become a standard safety check before they end up in products or the environment.
Sterile inflammation induced by respirable micro and nano polystyrene particles in the pathogenesis of pulmonary diseases
AI summary Read the abstract
Researchers exposed human lung and immune cells to polystyrene micro and nanoparticles and found they triggered a type of inflammation that does not require infection, called sterile inflammation. Aged (oxidized) particles and those that interacted with immune cells were especially potent at activating inflammatory pathways including the NLRP3 inflammasome. This suggests that breathing in airborne microplastics could cause chronic lung inflammation over time.
