Multiple sclerosis is a systemic venous vasculopathy: A single unifying mechanism

Medical Hypotheses

Abstract

Multiple sclerosis (MS) is a potentially debilitating disease affecting the central nervous system (CNS) clinically characterized by progressive neurological deterioration. It is the most common condition under the umbrella of demyelinating disease, thought to occur as a result of a primary autoimmune insult. Various genetic and environmental risk factors have been implicated as potential triggers and/or predisposing factors; however, the exact mechanism of disease remains elusive. Diagnosis and management are based on clinical presentation, with adjunct imaging and biochemical assessment. Since the 19th century anatomical distribution of lesions in MS have been observed to demonstrate a characteristic periventricular, perivenular distribution; spinal cord and cortical lesions also demonstrate this perivenous preponderance. Venous abnormalities have long been observed on pathology characterized by irregular narrowing and dilatation with associated venous wall and perivenous infiltrates. Active CNS lesions are characterized by perivenular inflammatory infiltrates. There is accompanying global dysfunction of the blood-brain barrier, even within normal appearing tissue, with low levels of inflammatory change and tissue injury seen...Continue Reading

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.

CSF & Lymphatic System

This feed focuses on Cerebral Spinal Fluid (CSF) and the lymphatic system. Discover the latest papers using imaging techniques to track CSF outflow into the lymphatic system in animal models.

Blood Brain Barrier Chips

The blood brain barrier (BBB) is comprised of endothelial cells that regulate the influx and outflux of plasma concentrations. Lab-on-a-chip devices allow scientists to model diseases and mechanisms such as the passage of therapeutic antibodies across the BBB. Discover the latest research on BBB chips here.

Blood Brain Barrier

The blood brain barrier is a border that separates blood from cerebrospinal fluid. Discover the latest search on this highly selective semipermeable membrane here.
