Lurcher (Lc) is a gain-of-function mutation in the delta2 glutamate receptor gene that results in a large, constitutive inward current in the cerebellar Purkinje cells of +/Lc mice. +/Lc Purkinje cells fail to differentiate fully and die during postnatal development. In normal mice, interactions with granule cells promote Purkinje cell dendritic differentiation. Partial destruction of the granule cell population in young +/Lc mice by x irradiation resulted in a significant increase in Purkinje cell dendritic growth and improved cytoplasmic structure but did not prevent Purkinje cell death. These results indicate two components to Purkinje cell abnormalities in +/Lc mice: a retardation/blockade of dendritic development that is mediated by interactions with granule cells and the death of the cell. Thus, the normal trophic effects of granule cell interaction on Purkinje cell development are absent in the +/Lc cerebellum, suggesting that granule cells are powerful regulators of Purkinje cell differentiation.
