Article Abstract

Background: Ischemic stroke, a major cause of disability and the second leading cause of death, poses a significant public health challenge. Post-stroke inflammation can harm the blood-brain barrier and worsen neurological deficits, which are key factors in neuronal damage in patients with ischemic stroke. Microglia are crucial in the central nervous system, involved in inflammation, neuronal damage, and repair after cerebral ischemia. While cellular immune metabolism has been widely studied, its role in ischamic stroke remains unclear.

Aim: This review aims to examine how inflammation affects the phenotypic characteristics of immune cells after ischemic stroke and to explore the effects of the immune metabolic microenvironment on the phenotypic profiles and functions of microglia in ischemic stroke.

Method: The review refers to the available literature in PubMed, searching for critical terms related to Ischemic stroke, neuroinflammation, microglia, and immunometabolism.

Result: In this review, we found that during stroke progression, microglia can dynamically switch between pro-inflammatory and anti-inflammatory phenotypes. Microglial glycometabolism includes oxidative phosphorylation and glycolysis, and lipid metabolism involves lipid synthesis and breakdown. Modulating the production of inflammatory mediator precursors can induce an anti-inflammatory phenotype in microglia.

Conclusion: Thus, studying microglial metabolic pathways and their products may offer new insights for ischemic stroke treatment.

Endovascular therapy (EVT) is standard care for acute ischemic stroke due to large vessel occlusion, but its availability is limited in areas with long distances. It has also been demonstrated that there are differences in the utilization of thrombectomy related to socioeconomic factors. The aim of this study is to examine regional differences in the utilization of mechanical thrombectomy and outcome within one comprehensive stroke center district in terms of distance and income.

20(R)-ginsenoside Rg3 can reduce the effects of oxidative stress and cell death in cerebral ischemia‒reperfusion injury (CIRI). Neuroinflammation is crucial post-CIRI, but how 20(R)-Rg3 affects ischemia‒reperfusion-induced neuroinflammation is unclear. To study 20(R)-Rg3's effects on neuroinflammation and neuronal preservation in stroke models and explore toll-like receptor 4/myeloid differentiation factor-88/nuclear factor kappa B (TLR4/MyD88/NF-κB) pathway mechanisms.

Introduction: Kidney stone disease is associated with numerous cardiovascular risk factors. However, the findings across studies are non-uniformly consistent, and the control of confounding variables remains suboptimal. This study aimed to investigate the association between kidney stone and cardiovascular disease.
