Summary
Platelet endothelial cell adhesion molecule-1 (PECAM-1) is crucial in neuroinflammation and blood-brain barrier function. Elevated PECAM-1 levels indicate disease activity in neurological disorders like multiple sclerosis and stroke.
Area of Science:
- Neuroscience
- Immunology
- Cell Biology
Background:
- Platelet endothelial cell adhesion molecule-1 (PECAM-1, CD31) is a key adhesion molecule involved in leukocyte-endothelium interactions and inflammation.
- Neuroinflammation and blood-brain barrier disruption are central to many neurological disorders.
Purpose of the Study:
- To review recent investigations on PECAM-1 biology and its role in neuroinflammation.
- To discuss PECAM-1 as a potential biomarker, therapeutic target, and prognostic factor in neurological conditions.
Main Methods:
- Review of recent scientific literature and experimental findings.
- Multidisciplinary discussion of PECAM-1's involvement in various neurological diseases.
Main Results:
- PECAM-1 and its soluble form (sPECAM-1) are elevated in active multiple sclerosis and after ischemic stroke.
- PECAM-1 is implicated in Alzheimer's disease, paraneoplastic neurological disorders, NeuroAIDS, brain trauma, and nerve root injury.
Conclusions:
- PECAM-1 plays a significant role in neuroinflammation and neurological disease pathogenesis.
- PECAM-1 and sPECAM-1 show potential as biomarkers and therapeutic targets for neurological disorders.

Overview
01:28Inflammation: Introduction
Inflammation is a fundamental, protective biological response of vascularized tissues to cellular injury, infection, or harmful stimuli. Its primary function is to eliminate the initial cause of injury, clear necrotic cells and damaged tissue, and initiate the necessary repair processes.Cardinal SignsAcute inflammation presents with classic signs. Redness results from vasodilation and increased blood flow. Heat is due to increased metabolism and circulation. Swelling results from the...
01:12Chronic Inflammation: Introduction
Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
01:28Inflammatory Response
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

01:27Psychoneuroimmunology: Cardiovascular Disease
Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...
