Nuclear inclusions in paraventricular nucleus neurons of the rat hypothalamus

Nuclear inclusions in paraventricular nucleus neurons of the rat hypothalamus

M Lafarga et al. Cell Tissue Res. 1979.

Abstract

This paper deals with the ultrastructure of two types of intranuclear inclusions, "microfilamentous spindle-shaped" and "crystalloid", present in paraventricular nucleus neurons of adult normal rats. These inclusions appear occasionally in some non-secretory neurons of the parvocellular system, but have never been seen in neurosecretory cells of the magnocellular system. The microfilamentous spindle-shaped inclusions show a close spatial relationship with the granulofibrillar body and interchromatin granules. The distribution and functional significance of such structures are discussed in the light of recent ultrastructural and biochemical studies on nuclear inclusions.
