Autonomic nervous system regulation of murine immune responses as assessed by local surgical sympathetic and parasympathetic denervation.
The effect of local sympathetic denervation on immune responses of submaxillary lymph nodes (SmLN) of mice was examined in animals subjected to unilateral superior cervical ganglionectomy (SCGx). Norepinephrine (NE) content in ipsilateral SmLN decreased by 90% 7-20 days after SCGx, while bilateral S...
