Abstract
The distribution of immunoreactivity to the neurokinin3 receptor (NK3R) was examined in segments C7, T11-12, L1-2, and L4-6 of the rat spinal cord. NK3R immunoreactivity was visualized by using two antisera generated against sequences of amino acids contained in the C-terminal region of the NK3R. NK3R-immunoreactive cells were numerous in the substantia gelatinosa of all spinal segments examined as well as the dorsal commissural nucleus of spinal segments L1-2. Isolated, immunoreactive cells were scattered throughout other regions of the spinal cord. The relationship of NK3R-immunoreactivity with neurons was demonstrated by colocalization with microtubule associated protein 2-immunoreactivity in individual cells. Within neurons, NK3R- immunoreactivity was associated predominately with the plasma membrane of cell bodies and dendrites. Within the substantia gelatinosa, 86% of nitric oxide synthase (NOS)-immunoreactive neurons were also NK3R-immunoreactive. Although NOS-immunoreactive neurons were found throughout all other regions of the spinal cord in the segments examined, these were not NK3R- immunoreactive. When preganglionic sympathetic neurons in spinal segments T11-12 and L1-2 were visualized by intraperitoneal injection of Fluorogold, less than 1% of the Fluorogold-labeled neurons were also immunoreactive for NK3R. The large number of NK3R-immunoreactive neurons in the substantia gelatinosa suggests that some effects of tachykinins an somatosensation may be mediated by NK3R.
