Reduced adolescent risk-assessment and lower nicotinic beta-2 expression in rats exposed to nicotine through lactation by forcedly drinking dams
Few animal studies focus on consequences of nicotine postnatal exposure, particularly through lactation. We have recently shown that forced nicotine drinking elevates maternal care, paradoxically provoking arousal and stress in pups. Present work aimed to evaluate the specific contribution of altered maternal cares, compared to the sequelae merely due to nicotine effects.
