    Role in Disease: Glial Dysfunction and Neurological Disorders

    Introduction

    Glial dysfunction has emerged as a critical factor in the pathophysiology of various neurological diseases, including multiple sclerosis, Alzheimer’s disease, and gliomas.

    Key Concepts

    The Role of Glial Cells

    Glial cells, which include astrocytes, microglia, and oligodendrocytes, are crucial in maintaining the central nervous system (CNS). They provide structural support, promote neuronal repair, and modulate synaptic function. Dysfunctional glial cells can lead to:

    • Increased neuroinflammation
    • Disruption of the blood-brain barrier
    • Impaired myelination in the case of multiple sclerosis
    • Accumulation of amyloid-beta in Alzheimer’s disease

    Biomechanics Perspective

    From a biomechanics perspective, the mechanical properties of the extracellular matrix and the biomechanical behavior of glial cells can significantly influence neuronal health and disease progression. Alterations in these biomechanical properties may affect how glial cells respond to injury and inflammation, highlighting the importance of biomechanics in understanding glial function in health and disease.
