Transneuronal Degeneration in Different Inbred Strains of Mice: A Preliminary Study of Olfactory Bulb Events After Olfactory Nerve Lesion

Abstract

Cytological analysis of the olfactory bulb was performed in two inbred strains of mice SEC/1 ReJ and C57/B16J after the lesion of the olfactory nerve. The data show an enhanced transneural degeneration in C57 mice as compared to the controls, while in the SEC mice this phenomenon did not exceed the level of spontaneous degeneration previously described by other authors. On the basis of our findings two different genetically adaptive systems are hypothesized and correlated with onto-genetical data.
