Immunocytochemical detection of vitamin D-dependent calcium-binding protein (CaBP-28K) in vestibular sensory hair cells and vestibular ganglion neurones of the cat.
Vestibular sensory hair cells, afferent fibres and vestibular ganglion neurones of the cat are intensely labelled by a specific antibody to rat kidney vitamin D-dependent calcium-binding protein (CaBP-28K). Type I hair cells are more weakly CaBP immunoreactive than type II hair cells. Ganglion neurones also present a differential staining. The presence of calcium-binding protein in sensory hair cells could be of interest for the understanding of transductional mechanisms.
