Rohde Cells (Spinal) plays an important role in the study of neurodegenerative diseases. This page provides comprehensive information about this topic, including its mechanisms, significance in disease processes, and therapeutic implications.
Introduction
Spinal Rugosa Cells, also known as rugosa-like cells or substantia gelatinosa cells, are specialized [neurons](/entities/neurons) located in the dorsal horn of the spinal cord, particularly in laminae I-II (Rexed laminae). These cells play critical roles in pain processing, temperature sensation, and itch transmission. The term rugosa refers to their characteristic wrinkled or folded nuclear morphology observed in histological preparations. Recent research has demonstrated important connections between spinal cord dorsal horn dysfunction and neurodegenerative processes, with implications for understanding chronic pain conditions in neurodegenerative diseases.

Neuroanatomy
Location in Spinal Cord
Lamina I (Marginal Layer): Outer dorsal horn
Lamina II (Substantia Gelatinosa): Inner dorsal horn, highest density
Lamina III: Outer zone of nucleus proprius
Dorsal Root Entry Zone: Peripheral process termination
