Abstract

Insights

High adiponectin levels may protect against cerebral microbleeds (CMBs), while soluble E-selectin is linked to their increased prevalence. This suggests endothelial dysfunction plays a role in CMBs.

Area of Science:

  • Neurology
  • Vascular Biology
  • Biomarkers

Background:

  • Cerebral microbleeds (CMBs) are key indicators of cerebral small vessel disease.
  • The role of endothelial dysfunction in CMB development remains unclear.
  • This study investigates the relationship between specific biomarkers and CMB prevalence.

Purpose of the Study:

  • To explore the correlation between serum levels of adiponectin and soluble E-selectin (sE-selectin) and the presence of CMBs.
  • To assess the potential role of endothelial dysfunction in the pathogenesis of CMBs.

Main Methods:

  • Prospective study of 126 patients with first-ever ischemic stroke.
  • Detection and evaluation of CMBs using susceptibility-weighted magnetic resonance imaging.
  • Measurement of serum adiponectin and sE-selectin levels.

Main Results:

  • CMBs were detected in 50% of patients, more common in mixed brain regions.
  • Increased adiponectin levels showed a significant inverse association with CMB prevalence (OR = 0.55).
  • Elevated sE-selectin levels demonstrated a significant positive association with CMB prevalence (OR = 1.09).
  • sE-selectin and adiponectin levels were inversely correlated (r = -0.452, p = 0.001).

Conclusions:

  • Endothelial injury is implicated in the pathogenesis of CMBs.
  • Serum adiponectin and sE-selectin levels are closely associated with CMBs.
  • Adiponectin may exert a protective effect against the prevalence of CMBs.

Ischemic Stroke l: Introduction

Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
Ischemic Stroke ll: Pathophysiology01:15

Ischemic Stroke ll: Pathophysiology

An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
Hemorrhagic Stroke l: Introduction01:17

Hemorrhagic Stroke l: Introduction

A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...

Hemorrhagic Stroke ll: Pathophysiology

A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
Selectins01:25

Selectins

Cell adhesion is  an essential aspect of multicellularity. While stable cell interactions usually occur between cells of the same type, transient cell interactions occur between cells of different tissue types, such as between neutrophils and endothelial cells. Selectins are one class of cell adhesion molecules (CAMs) that bind carbohydrate ligands to form transient cell adhesion. They are rod-like proteins with a long extracellular part of variable length ending with the lectin domain, which...

Blood Studies for Cardiovascular System III: Serum Lipid Profile

Understanding serum lipids is crucial for maintaining cardiovascular health and preventing heart disease and stroke.
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
