A Sympathetic-Adrenal Neuroimmune Reflex Linked to the Immunosuppressive Effects of Spinal Cord Injury

A Sympathetic-Adrenal Neuroimmune Reflex Linked to the Immunosuppressive Effects of Spinal Cord Injury

A recent study published in Nature Neuroscience indicates that the increased susceptibility to life-threatening infections in spinal cord injury (SCI) patients may result from the disruption of the physiological interactions within a neuroendocrine reflex involving the sympathetic nervous system (SNS) and the adrenal glands. The control of the immune system by the peripheral autonomic nervous […]

Sympathetic Nerves via β2-adrenoceptor Signaling Generate Circadian Rhythms and Govern Lymphocyte Recirculation in Lymph Nodes

A new study, published in the Journal of Experimental Medicine (JEM), indicates that in mice, the sympathetic nervous system (SNS) innervation, through β2-adrenergic receptors activation controls the circadian dynamics and traffic of lymphocytes through the lymph nodes (LNs). Both primary and secondary lymphoid organs are heavily innervated, mostly by the peripheral sympathetic nerves. Thus, locally […]
