Article Abstract
Background: Rupture of vulnerable plaque with subsequent thrombus formation has been implicated as the most common pathogenic mechanism responsible for acute coronary syndrome (ACS). Angiographic coronary lesion complexity has been reported to reflect plaque vulnerability. Macrophage migration inhibitory factor (MIF) is a proinflammatory cytokine and might be involved in the pathophysiology of atherosclerotic plaque destabilization.
Objective: This study was designed to investigate if serum MIF levels are associated with angiographic coronary lesion complexity in patients with coronary artery disease (CAD).
Materials And Methods: A total of 232 consecutive CAD patients and 76 controls were recruited. CAD patients were subdivided according to the presence of ACS (n=138) or stable angina pectoris (SAP) (n=98). Coronary lesion morphology was assessed by coronary angiography. Serum MIF levels were measured by an enzyme-linked immunosorbent assay.
Results: SAP patients had significantly higher serum MIF levels compared with healthy controls, and ACS patients had significantly higher serum MIF levels compared with SAP patients. In SAP patients, serum MIF levels were independently associated with the presence of complex coronary lesion. In ACS patients, serum MIF levels increased in conjunction with the extent of complex lesions.
Conclusions: Serum MIF levels are a potential biomarker for reflecting the presence and severity of angiographically complex coronary lesion in CAD patients.

Macrophage Migration Inhibitory Factor (MIF) is a pleiotropic cytokine that acts as a central regulator of inflammation and immune responses across diverse organ systems. Functioning upstream in immune activation cascades, MIF influences macrophage polarization, T and B cell differentiation, and cytokine expression through CD74, CXCR2/4/7, and downstream signaling via NF-κB, ERK1/2, and PI3K/AKT pathways. This review provides a comprehensive analysis of MIF's mechanistic functions under both physiological and pathological conditions, highlighting its dual role as a protective mediator during acute stress and as a pro-inflammatory amplifier in chronic disease.

Hydrogen-rich water (HRW) has shown neuroprotective effects in acute brain injury, but its role in chronic radiation-induced brain injury (RIBI) remains unclear. This study investigated the long-term efficacy of HRW in mitigating cognitive impairment and neuronal damage caused by chronic RIBI. Fifty male Sprague Dawley rats were randomly divided into five groups: control, irradiation (IR), IR with memantine, IR with HRW, and IR with combined treatment.

Abstract: The aim of this study was to investigate the mechanism by which chronic stress (CS) induces non-alcoholic fatty liver disease (NAFLD)-like changes, and the role of oxidative stress and the NLRP3 inflammasome in this mechanism. Transcriptomic data extracted from the Sequence Read Archive (SRA) at the NCBI were employed to identify the molecular targets of CS-induced NAFLD. Fifty 8-week-old healthy male Wistar rats were divided into five groups (n = 10 each) as follows: control, CS, CS + mifepristone (CS + Mif), CS + metyrapone (CS + Met), and corticosterone (Cort).

Endometriosis is the extrauterine engraftment of endometrium-like tissue, causing chronic pain. Complex sensory-vascular-immune interactions, including growth factors, cytokines, and neuropeptides, are implicated in its pathophysiology, but the mechanisms remain unknown. Here, epidermal growth factor (EGF), vascular endothelial growth factor, interleukins (IL-1β, IL-6, IL-8), macrophage migration inhibitory factor (MIF), calcitonin gene-related peptide, and somatostatin were measured in the serum of endometriosis patients with different disease severities, menstruation cycle- and pharmacotherapy-related hormonal status compared with controls.
