Pacinian Corpuscle Cells is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes. [1]
Pacinian corpuscles (also called lamellar corpuscles) are encapsulated mechanoreceptors located deep in the dermis and subcutaneous tissue that detect high-frequency vibration and pressure. These rapidly adapting receptors are among the largest sensory receptors in the human body and play critical roles in detecting fine vibrations essential for tactile perception and object manipulation.

Pacinian corpuscles are deep, rapidly adapting mechanoreceptors specialized for high-frequency vibration detection. Their function is impaired in Parkinson's disease, diabetic neuropathy, and chemotherapy-induced neuropathy, contributing to sensory deficits and functional limitations. These corpuscles work with Merkel cells and Meissner corpuscles to provide comprehensive tactile information for fine motor control and perception.
