Figure 5From: Nicotine signals through muscle-type and neuronal nicotinic acetylcholine receptors in both human bronchial epithelial cells and airway fibroblastsCalcium influx after exposure of BEAS2B cells in the presence of antagonist. BEAS2B cell were exposed to 1 μM nicotine in the presence or absence of nAChR antagonist. Intracellular calcium-45 was measured after exposure to nicotine for 5 minutes. * statistically significant as compared to untreated control.Back to article page
