Introduction
Meissner 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. [@abraira2021]
Meissner corpuscles (also called tactile corpuscles or Merkel cell-neurite complexes in some contexts) are specialized mechanoreceptor cells in the skin responsible for detecting light touch, vibration, and texture. These encapsulated nerve endings are essential for fine tactile discrimination and have been implicated in neurodegenerative diseases through their connection to sensory neuropathy.
