Ferroptosis, a novel form of cell death driven by iron and characterized by the accumulation of reactive oxygen species (ROS), has been associated with the progression of IDD. Nicotinamide adenine dinucleotide phosphate oxidase 4 (NOX4) has been widely recognized as a pivotal factor promoting ferroptosis across various diseases; however, its precise role in the pathogenesis of IDD remains incompletely understood. Our experimental findings demonstrated a marked upregulation of NOX4 in degenerated cells, accompanied by elevated ROS levels and a diminished mitochondrial membrane potential, indicating the participation of ferroptosis. Furthermore, the expression of the critical regulatory factor GPX4 was reduced, while ACSL4 levels were significantly increased, further corroborating the involvement of ferroptosis. Functional loss and gain experiments revealed that NOX4 overexpression augmented ferroptosis and ROS production while promoting the secretion of inflammatory cytokines. Subsequent studies indicated that the knockdown of NOX4 could reverse tert-butyl hydroperoxide (TBHP)-induced ferroptosis. Mass spectrometry analysis identified leucine-rich repeat-containing 8A (LRRC8A) as an interacting protein of NOX4, and further validation confirmed that they co-regulate Nod-like receptor pyrin domain-3 (NLRP3) activation through their interaction.

These bioreactors allow researchers to recreate specific vascular environments, providing a controlled setting for studying the effects of blood flow, mechanical stress, and biochemical factors on vascular tissues. Through these systems, researchers can explore how physical and chemical cues contribute to disease processes and cellular responses, enhancing our understanding of disease progression. Bioreactor studies have demonstrated that hemodynamic forces, particularly shear stress, influence endothelial cell behavior and play a role in vascular pathologies. For instance, in atherosclerosis, disturbed flow patterns are associated with endothelial dysfunction and plaque development. By simulating these conditions, bioreactors provide insight into the effects of mechanical forces on vascular wall biology, highlighting how altered flow can contribute to disease. Bioreactors also support studies on the impacts of pulsatile flow and circumferential stress, allowing a closer approximation of physiological environments. Beyond flow dynamics, these systems facilitate investigation into how vascular cells respond to biochemical signals, inflammatory markers, and therapeutic interventions. This integrated approach allows for a more complete picture of the factors involved in vascular disease. Recent advancements, such as vessel-on-a-chip models and artery-mimicking setups, extend the capabilities of bioreactors by enabling researchers to model a broader range of conditions relevant to human physiology. In vasculitis studies, bioreactors help explore immune interactions with endothelial cells, especially with stem cell-derived cells that replicate patient-specific responses. Bioreactors also play a role in vascular tissue engineering, particularly in assessing materials and scaffold-free designs that may reduce inflammation in vascular grafts. These efforts contribute to the ongoing search for more compatible graft materials, with the potential to improve outcomes in clinical applications.

NLRP3 inflammasome activation was examined mechanistically in the context of different nicotine dosages. We show NLRP3 inflammasome activation, apoptosis-associated speck-like protein (ASC) expression, caspase-1 activity and subsequent IL-1β secretion were positively correlated with nicotine in a dose-dependent relationship, and destabilization of lysosomes and ROS production were also involved. At high concentrations of nicotine surpassing 0.25 mM, NLRP3 inflammasome activity declined, along with increased expression of the anti-inflammatory Alpha7 nicotinic acetylcholine receptor (α7nAChR) and the inhibition of TLR4/NF-κB signaling. Consequently, high doses of nicotine also reduced ASC expression, caspase-1 activity and IL-1β secretion in macrophages.
