研究目的:

探索AS微环境中的IFN-γ和ox-LDL协同调控APC-N分化的具体分子机制,揭示APC-N促进AS进展的关键作用,以期为AS的治疗提供药物作用靶点,为AS的预后提供预测指标。  

Objectives of Study:

This study aims to investigate the specific molecular mechanisms through which IFN-γ and ox-LDL synergistically regulate the differentiation of APC-N within the atherosclerotic microenvironment, and to elucidate the critical role of APC-N in promoting the progression of atherosclerosis (AS). The ultimate objectives are to identify potential therapeutic targets for AS intervention and to establish prognostic biomarkers for the disease.

Inclusion criteria

1. Confirmed diagnosis: Patients (aged 18–80 years) diagnosed with ischemic stroke (IS) through clinical assessment (NIHSS score) and imaging (cranial CT/MRI-DWI), and who agree to participate in this clinical trial; 2. Large vessel occlusion (internal carotid artery, M1/M2 segment of the middle cerebral artery, basilar artery) confirmed by cerebrovascular angiography (DSA/CTA); 3. Sample collection: Patients undergoing mechanical thrombectomy (stent retrieval and/or aspiration catheter) with successful intraoperative acquisition of intact thrombus specimens (>=1 fragment, diameter >2 mm). The neurointerventional team must assess sample eligibility in real time in the catheterization laboratory; 4. For cardioembolic stroke (e.g., atrial fibrillation, valvular disease, intracardiac thrombus), a history of anticoagulant therapy (INR value/duration of anticoagulant use) must be documented; 5. For large artery atherosclerosis with vascular stenosis >=50% or vulnerable plaque (confirmed by HR-MRI), the intensity of lipid-lowering therapy (LDL-C level) must be recorded; 6. Key time points: Time from symptom onset to femoral artery puncture <=24 hours (anterior circulation) or <=12 hours (posterior circulation); 7. Post-thrombectomy cranial imaging review completed within 24 hours (to exclude hemorrhagic transformation).

Pre-existing Severe Disability: Pre-stroke modified Rankin Scale (mRS) score ≥ 2, indicating significant pre-existing neurological disability. 3.

Exceeding Time Window: Time from symptom onset to femoral artery puncture exceeds the specified windows (>24 hours for anterior circulation or >12 hours for posterior circulation). 12. Inability to Complete Follow-up: Inability to complete the clinical and imaging follow-ups as required by the study protocol due to geographical, social, or psychological reasons. 13. Pregnancy or Lactation: Pregnancy, lactation, or intention to become pregnant within the next 6 months for women of childbearing potential (unless a negative blood/urine pregnancy test is confirmed). 14. Allergy: Documented history of allergy to contrast agents, anesthetics used in the study, or drugs that may be used in subsequent analyses. 15. Participation in Other Clinical Trials: Concurrent participation in another interventional clinical trial that may interfere with the outcome assessment of this study. 16.
