Figure 4From: Divergent effects of norepinephrine, dopamine and substance P on the activation, differentiation and effector functions of human cytotoxic T lymphocytesMigratory activity of activated CD8+ T lymphocytes. Each graph shows on the left side the time-course of the mean migratory activity and on the right side the time-average of the migratory activity as mean value and standard deviation of the same experiments. Three experiments were performed with each neurotransmitter: (A) 10 ÎĽM norepinephrine, (B) 1 ÎĽM dopamine, (C) 1 ÎĽM substance P. For each experiment, blood from different donors was used. Asterisks mark statistically significant changes (p < 0.05).Back to article page
