1 Pre-incubation of the isolated mitochondria with nicotine prevented from dissipation of their membrane potential stimulated with 0.8 microM CaCl2 depending on the dose, and this effect was strengthened by the antagonist of alpha7 nicotinic receptors (alpha7 nAChR) methyllicaconitine. Nicotine cholinergic receptor, nicotinic, alpha polypeptide 7 Mus musculus
2 It is concluded that nicotine consumption worsens the functional state of mitochondria by affecting their membrane potential and granularity, and this effect, at least in part, is mediated by alpha7 nAChR desensitization. Nicotine cholinergic receptor, nicotinic, alpha polypeptide 7 Mus musculus
