Identification and distribution of alpha-melanotropin in discrete regions of the cat brain.
The distribution of alpha-melantropin-like material (alpha-MSH) was demonstrated in rat brain using a microdissection technique combined with radioimmunoassay. Highest concentrations of alpha-MSH were noted in the hypothalamus and preoptic area. Particularly high concentrations were observed in the arcuate nucleus, median eminence, suprachiasmatic nucleus, periventricular nucleus and the medial preoptic nucleus. The thalamic paraventricular nucleus also contained high alpha-MSH concentrations. Moderate to low concentrations were noted in other thalamic, septal, amygdaloid and midbrain nuclei. Low concentrations were observed in cortical and striatal regions.
