Rho GTPases are key regulators of the activity-dependent changes of neural circuits. Besides being involved in nervous system development and repair, this neural structural plasticity is believed to constitute the cellular basis of learning and memory. Here we report that concurrent modulation of cerebral Rho GTPases, including Rac, Rho and Cdc42 subfamilies, by Cytotoxic Necrotizing Factor 1 (CNF1,...
Cerebral Rho GTPases are crucially involved in cognitive abilities. This activity is thought to be related to the regulation of actin polymerization and, thereby, of the shape of the dendritic tree. Here we report that Cytotoxic Necrotizing Factor 1 (CNF1, 1fmol/kgicv), a bacterial protein endowed with Rho GTPase activating properties, enhances working memory for object location/discrimination in...
