Endothelial dysfunction, characterized by a decline in endothelial physiological functions, is a significant aspect of cardiovascular aging, contributing notably to arterial stiffness, atherosclerosis, and hypertension. Transient receptor potential channel V4 (TRPV4), a key member of Ca-permeable channels, plays a crucial role in maintaining vascular functions. However, the role and mechanisms of TRPV4 in aging-related endothelial dysfunction remain incompletely understood.

Endothelial-to-mesenchymal transition (EndMT) is a cellular reprogramming mechanism by which endothelial cells acquire a mesenchymal phenotype. Endothelial cell dysfunction is the initiating factor of atherosclerosis (AS). Increasing evidence suggests that EndMT contributes to the occurrence and progression of atherosclerotic lesions and plaque instability.

The persistence or emergence of long-term symptoms following resolution of primary SARS-CoV-2 infection is referred to as long COVID or post-acute sequelae of COVID-19 (PASC). PASC predominantly affects the cardiovascular, neurological, respiratory, gastrointestinal, reproductive, and immune systems. Among these, the central nervous system (CNS) is significantly impacted, leading to a spectrum of symptoms, including fatigue, headaches, brain fog, cognitive impairment, anosmia, hypogeusia, neuropsychiatric symptoms, and peripheral neuropathy (neuro-PASC).

Introduction: Apolipoprotein E (ApoE) plays a crucial role in lipid homeostasis, predominantly expressed in astrocytes and to a lesser extent in microglia within the central nervous system (CNS). While the allele is the strongest genetic risk factor for late-onset Alzheimer's disease (AD), its precise role in AD pathogenesis remains elusive. -knockout (-ko) mice, mice expressing human , and human carriers exhibit similar deficits in lipid metabolism, cognitive and behavioral functions, and neurodegeneration.

The close interaction of mitochondrial fission and mitophagy, two crucial mechanisms, is key in the progression of myocardial ischemia-reperfusion (IR) injury. However, the upstream regulatory mechanisms governing these processes remain poorly understood. Here, we demonstrate a marked elevation in Nr4a1 expression following myocardial IR injury, which is associated with impaired cardiac function, heightened cardiomyocyte apoptosis, exacerbated inflammatory responses, and endothelial dysfunction.
