Abstract: | The ontogeny of cell adhesion molecule L1 in cerebellum was quantitatively assessed in weaver and reeler mutant mice and in heterozygous litter-mate controls. In the latter the concentration and the amount of L1 both increased from the first postnatal week to become maximum at the second. In contrast, in the weaver and reeler neurologic mutant mice, L1 decreased steadily. The L1 concentration and the amount of L1 was lower in the cerebellum of homozygous mutant mice than in litter-mate controls. The findings are consistent with L1 being a component of axonal plasma membranes. However, no evidence was found of any direct effect of thewv andrl phenotypes on L1 expression. |
