Anatomical mapping of choline acetyltransferase (ChAT)-like and glutamate decarboxylase (GAD)-like immunoreactivity in outer hair cell efferents in adult rats.

B J Dannhof1, B Roth, V Bruns.   

Abstract

The distribution of choline acetyltransferase (ChAT)-like and glutamate decarboxylase (GAD)-like immunoreactivity in the cochleae of 15 adult Wistar white rats was investigated using the peroxidase-antiperoxidase (PAP) technique. A monoclonal antibody to ChAT and a polyclonal antiserum to GAD were used. Immunoreaction was investigated quantitatively, in the electron microscope, on tangential sections of the tunnel of Corti and the rows of outer hair cells. ChAT-like and GAD-like immunoreactivity was found in all efferent nerve fibres in the tunnel of Corti and in all efferent synapses on the outer hair cells. A coexistence of ChAT and GAD in the efferent system to the outer hair cells of the rat is therefore assumed.
