abstract：:HEL 92.1.7 cells were immobilized among nerve growth factor (NGF)-differentiated PC12 cells. Nicotine caused an immediate Ca2+ mobilisation in the PC12 cells followed by a delayed secondary Ca2+ response in the HEL 92.1.7 cells. The Ca2+ elevation in response to nicotine in PC12 cells was abolished by Na+ removal. The...
