To clarify the mechanism underlying the process of degeneration of injured CNS neurons, we have immunohistochemically examined the distribution of cystatin C, apolipoprotein E, IgG, transferrin and ferritin in the hypophysectomized rat hypothalamus. Stainings for ferritin revealed that reactive microglial cells massed in the paraventricular and supraoptic nuclei 14 days after hypophysectomy, when the degeneration of vasopressin neuronal cell bodies was apparent. Cystatin C-positive magnocellular neurons first appeared at 4 days and the number of intensely-stained cells increased rapidly up to the 7th day of hypophysectomy, followed by a decrease thereafter. Most of such cystatin C-positive neurons were simultaneously stained with anti-vasopressin serum. Accumulation of apolipoprotein E in extracellular spaces was obvious in the both hypothalamic magnocellular nuclei at 7 days. Several apolipoprotein E-positive cells were localized in the supraoptic nucleus, although the number of apolipoprotein E-positive cells was much smaller than that of cystatin C-positive cells. The experiments performed with the transferrin and IgG antibodies showed undetectable levels of such molecules in and around the degenerating magnocellular neurons during whole experimental periods. These findings suggest the importance of cystatin C and apolipoprotein E in the process of degeneration and/or regeneration of magnocellular neurons after hypophysectomy.
