K. Dekkerohno et al., ENDOPLASMIC-RETICULUM IS MISSING IN DENDRITIC SPINES OF PURKINJE-CELLS OF THE ATAXIC MUTANT RAT, Brain research, 714(1-2), 1996, pp. 226-230
Dilute-opisthotonus (dop) is a spontaneous ataxic mutation in the rat,
regulated by an autosomal recessive gene. Immunohistochemical stainin
g with anti-inositol 1,4,5-trisphosphate receptor antibody and electro
n microscopic examinations revealed that the endoplasmic reticulum in
dendritic spines of Purkinje cell was missing in the ataxic rat. This
could impair the intracellular signal transduction in the parallel fib
er-Purkinje cell synapse, and be a cause of the seven ataxic movement.
