In recent years, neurovascular unit (NVU) which is composed of neurons, astrocytes (Ast), microglia (MG), vascular cells and extracellular matrix (ECM), has become an attractive field in ischemic stroke. As the important component of NVU, Ast closely interacts with other constituents, which has been playing double-edged sword roles, beneficial or detrimental after ischemic stroke. Based on the pathophysiological changes, we evaluated some strategies for targeting Ast in treating ischemic stroke. The present review is focused on the roles of Ast in NVU and its complex signaling molecular network after ischemic stroke, which may be a prospective approach to the treatment of ischemic diseases in central nervous system.

Growth-differentiation factor 15 (GDF-15) is a cytokine involved in cellular stress responses and inflammation. This meta-analysis evaluates the association between circulating GDF-15 levels and functional outcomes in patients with acute ischemic stroke (AIS). A comprehensive search of Medline, Web of Science, Embase, Wanfang, and CNKI was conducted up to July 15, 2024.

Impact of percutaneous left atrial appendage occlusion on the severity of ischemic stroke.

Cardiovasc Revasc Med

December 2024

Division of Cardiovascular Medicine, University of Toledo Medical Center, Toledo, OH, United States of America. Electronic address:

Background: Percutaneous left atrial appendage occlusion (pLAAO) presents an alternative to anticoagulation (AC) for stroke prophylaxis in atrial fibrillation (Afib) patients with high bleeding risk. pLAAO was associated with lower rates of disabling stroke which was mainly attributed to the reduction of hemorrhagic stroke (HS). Little is known about the impact of pLAAO on the severity of ischemic strokes which we sought to study.

Objectives: Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive neurostimulation technique that uses magnetic field to comprehensively influence events in the brain. Its use in patients after stroke focuses mainly on influencing brain neuroplasticity and therefore has the potential to improve motor functions in these patients. This study investigates the effect of rTMS on motor function recovery in patients in the acute stage of ischemic stroke.

Early neurological deterioration in acute ischemic minor stroke patients with large vessel occlusion following intravenous thrombolysis.

World Neurosurg

December 2024

Department of Neurology, Nanjing Pukou People's Hospital, No. 166 Shanghe Street, Jiangpu Subdistrict, Pukou District, Nanjing, 210000, China. Electronic address:

Objective: Early identification of risk factors associated with early neurological deterioration (END) in patients with acute minor stroke and large vessel occlusion (LVO) receiving intravenous thrombolysis (IVT) could assist in formulating treatment decisions.

Methods: Consecutive patients with acute minor stroke and LVO were extracted from a single-center prospective database spanning January 2020 to December 2023. END was defined as an increase of ≥ 4 points in the National Institutes of Health Stroke Scale (NIHSS) score from baseline, or ≥ 2 points in any single NIHSS item, within 24 hours of the IVT.

Current state of epigenetics in giant cell arteritis: Focus on microRNA dysregulation.

Autoimmun Rev

December 2024

Institute of Pathology, Faculty of Medicine, University of Ljubljana, Ljubljana, Slovenia. Electronic address:

Giant cell arteritis (GCA) is a primary systemic vasculitis affecting the elderly, characterized by a granulomatous vessel wall inflammation of large- and medium-sized arteries. The immunopathology of GCA is complex, involving both the innate and adaptive arms of the immune system, where a maladaptive inflammatory-driven vascular repair process ultimately results in vessel wall thickening, intramural vascular smooth muscle cell proliferation, neovascularization and vessel lumen occlusion, which can lead to serious ischemic complications such as visual loss and ischemic stroke. Over the past decade, microRNA (miRNA) dysregulation has been highlighted as an important contributing factor underlying the pathogenesis of GCA.
