1 Herein, we report that nicotine, an unselective alpha7-nAChR agonist, protects from morphological and synaptic impairments induced by Abeta oligomers. Nicotine cholinergic receptor, nicotinic, alpha polypeptide 7 Mus musculus
2 On the other hand, a cross-talk between alpha7-nAChR and the Wnt/beta-catenin signaling pathway was revealed by the following facts: (1) nicotine stabilizes beta-catenin, in a concentration-dependent manner; (2) nicotine prevents Abeta-induced loss of beta-catenin through the alpha7-nAChR; and (3) activation of canonical Wnt/beta-catenin signaling induces alpha7-nAChR expression. Nicotine cholinergic receptor, nicotinic, alpha polypeptide 7 Mus musculus
3 On the other hand, a cross-talk between alpha7-nAChR and the Wnt/beta-catenin signaling pathway was revealed by the following facts: (1) nicotine stabilizes beta-catenin, in a concentration-dependent manner; (2) nicotine prevents Abeta-induced loss of beta-catenin through the alpha7-nAChR; and (3) activation of canonical Wnt/beta-catenin signaling induces alpha7-nAChR expression. Nicotine cholinergic receptor, nicotinic, alpha polypeptide 7 Mus musculus
