Satellite Glial Cells (PNS)

Introduction

Satellite Glial Cells (Pns) is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.

Overview

Satellite Glial Cells (PNS) are a specialized cell type classified within the Glial > Peripheral > Satellite lineage. These cells are primarily found in Dorsal root ganglia, Sensory ganglia and are characterized by expression of marker genes including [GFAP](/entities/gfap), S100B, EGFR, NG2 (CSPG4). They are selectively vulnerable in Chronic pain, Guillain-Barre Syndrome.

Morphology and Markers

Satellite Glial Cells (PNS) are identified by the expression of the following key marker genes:

• [GFAP](/genes/gfap)
• S100B
• EGFR
• NG2 (CSPG4)
• PLP1

These markers are used for immunohistochemical identification and single-cell RNA sequencing classification, as catalogued in the [Allen Cell Type Atlas](https://portal.brain-map.org/atlases-and-data/rnaseq).

Normal Function

Satellite Glial Cells (PNS) play essential roles in neural circuits and brain function. They are found in the following brain regions:

• Dorsal root ganglia
• Sensory ganglia

Their normal functions include maintaining neural circuit integrity, signal processing, and contributing to the homeostasis of their local microenvironment.

Vulnerability in Disease

Satellite Glial Cells (PNS) show selective vulnerability in the following neurodegenerative conditions:

• Chronic pain
• Guillain-Barre Syndrome

The selective vulnerability of these cells is an active area of research, with factors including metabolic demands, calcium handling, exposure to toxic protein aggregates, and cell-autonomous gene expression programs contributing to their susceptibility.
