Cells of Deiters

Cells of Deiters also known as Deiters' cells are specialized cells found in the organ of Corti in the cochlea of the inner ear. They were first described by the German anatomist Otto Deiters, after whom they are named.

Function

Deiters' cells have a crucial role in the functioning of the inner ear. They provide physical support to the outer hair cells (OHCs), which are essential for the amplification and fine-tuning of sound signals. Deiters' cells also play a role in the maintenance of the ionic environment of the OHCs, which is necessary for their proper functioning.

Structure

Deiters' cells are characterized by a long, thin process that extends towards the reticular lamina, ending in a small footplate that is in contact with the OHCs. They also have a large, round nucleus located at the base of the cell.

Clinical significance

Damage to Deiters' cells can lead to hearing loss, as they are essential for the proper functioning of the OHCs. Certain ototoxic drugs and loud noise exposure can cause damage to these cells.

Research

Research on Deiters' cells is ongoing, with studies focusing on their role in hearing and the mechanisms of their damage and repair. Understanding these cells better could lead to new treatments for hearing loss.
