cellular

abnormal mitochondrial morphology ( J:113147 )

• mitochondrial volume density in peripheral region of Purkinje cells within a subplasmalemmal cytoplasmic compartement of 1.5 microns is nearly double in mutant cells

• volume density of central mitochondria is not different from wild-type

• more mitochondria are present in the peripheral regions of Purkinje cells in mutants

abnormal Purkinje cell mitochondrial morphology ( J:113147 )

• total mitochondrial volume density in Purkinje cells of mutants is increased by ~40% compared to controls

• the surface of the membrane-enclosed cisternae just below the plasma membrane (sPL-sER) per surface of plasma membrane ratio is 30-40% smaller in Purkinje cells of mutants

nervous system

abnormal Purkinje cell mitochondrial morphology ( J:113147 )

• total mitochondrial volume density in Purkinje cells of mutants is increased by ~40% compared to controls

• the surface of the membrane-enclosed cisternae just below the plasma membrane (sPL-sER) per surface of plasma membrane ratio is 30-40% smaller in Purkinje cells of mutants
