Pyroptosis is a form of inflammatory programmed cell death activated by caspase-1 and caspase-4/5/11, and involves in the pathogenesis of infectious diseases and nervous system diseases. Pyroptosis is mediated by canonical inflammasome pathway and non-canonical inflammasome pathway. The canonical inflammasome pathway is activated in stroke and aggravates brain injury. Inhibition of inflammasome, caspase-1, IL-1β and IL-18 ameliorates brain injury. These studies indicate that canonical inflammasome pathway contributes to post-stroke brain injury, therefore, pyroptosis has become a potential therapeutic target for preventing excessive cell death during stroke. We reviewed the relationship between pyroptosis and stroke to provide some perspectives on future researches in this field.

Asthma is a chronic airway inflammatory disease that affects millions globally. Although glucocorticoids are a mainstay of asthma treatment, a subset of patients show resistance to these therapies, resulting in poor disease control and increased morbidity. The complex mechanisms underlying steroid-resistant asthma (SRA) involve Th1 and Th17 lymphocyte activity, neutrophil recruitment, and NLRP3 inflammasome activation.

Depression is a common and complex neuropsychiatric disorder affecting people of all ages worldwide, associated with high rates of relapse and disability. Neohesperidin (NEO) is a dietary flavonoid with applications in therapeutics; however, its effects on depressive-like behavior remain unknown. Here, we evaluated the effects of NEO on depressive-like behavior induced by chronic and unpredictable mild stress (CUMS).

Background: The misfolding and aggregation of the tau protein into neurofibrillary tangles constitute a central feature of tauopathies. Traumatic brain injury (TBI) has emerged as a potential risk factor, triggering the onset and progression of tauopathies. Our previous research revealed distinct polymorphisms in soluble tau oligomers originating from single versus repetitive mild TBIs.

Background: The connection between inflammasomes and Alzheimer's disease (AD) has garnered significant interest, with emerging evidence suggesting genetic associations and functional implications. Notably, studies have reported the upregulation of inflammasome components like NLRP1, NLRP3, and Caspase-1 in AD patients. Moreover, genetic polymorphisms in inflammasome-related genes are linked to increased AD risk.

Background: Alzheimer's disease (AD), also known as senile dementia, is the most common degenerative disease of the central nervous system. Neuroinflammation is currently believed to be a crucial factor in the progression of AD, while its exact mechanism remains unclear.
Method: APP/PS1 AD mice were treated with a natural active ingredient tetrahydroxy stilbene glucoside (TSG) at 40 mg/kg/day and 80 mg/kg/day respectively for 5 consecutive months, and then the Morris water maze test (MWM) and the novel object recognition test were performed to assess the effect of TSG on the cognitive and memory ability of AD mice.
