Characterization of hypothalamic neurons expressing a neuropeptide receptor, GALR2, using combined in situ hybridization-immunohistochemistry.

Our laboratory is interested in characterizing the neurotransmitter and hormonal phenotype of neurons in the rat hypothalamus expressing novel neuropeptide receptors of the neuropeptide Y and galanin families. In this review, we describe a technique combining nonradioactive in situ hybridization to detect mRNA and fluorescence immunohistochemistry to detect protein antigens. We examined paraffin sections of rat hypothalamus using confocal microscopy to determine whether mRNA for the galanin receptor, GALR2, was colocalized at the cellular level of resolution with somatostatin or tyrosine hydroxylase immunoreactivity. We found that many neurons in the hypothalamus expressed both GALR2 mRNA and either somatostatin or tyrosine hydroxylase immunoreactivity. The simultaneous detection of mRNA and protein immunoreactivity in individual neurons using the confocal microscope for visualization is an excellent tool for the analysis of newly characterized genes in the central nervous system.[1]
