Nullizygous mice lack hippocampal fast nicotinic currents but show nicotine-induced seizures as well as altered anxiety behavior, fertility defects, airway basal cell hyperplasia. and higher TNF sythesis when endotoxemic. Newborns homozygous for a knock-in allele die with increased neuron apoptosis.
