  2. 1. An experimental study on the interaction between the neuro-endocrine and immune systems in the gastrointestinal tract

    Author : Bi-Feng Qian; Eva Ekblad; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gastrointestinal tract; neuro-endocrine system; substance P; vasoactive intestinal polypeptide; vagus nerves; mucosal immune system; T lymphocytes; cytokines; inflammation; mouse;

    Abstract : The mucosa lining of the gastrointestinal (GI) tract is in immediate contact with food nutrients to allow a rapid and efficient digestion and absorption and at the same time protects against the incessant risk of attack from pathogenic microbes. Maintenance of normal physiological activities in the GI tract is dependent on a number of regulatory interactions between the nervous, endocrine, and immune systems, as well as environmental and genetic factors.

    Abstract : Vagus nerve stimulation (VNS) is an adjunctive palliative neuromodulatory treatment for drug resistant epilepsy (DRE) and chronic depression. It has also been proposed as a treatment for many other conditions such as chronic pain, heart failure, and Alzheimer’s disease. READ MORE

  6. 4. Neuro-immune communication: role of the vagus nerve : an electrophysiological study

    Author : Violeta Bucinskaite; Karolinska Institutet; Karolinska Institutet; []
    Keywords : cholecystokinin; CCKA; CCKB; cytokines; IL-1[beta]; illness; nerve activity; NIDDM; OLETF; the vagus; vagotomy;

    Abstract : Defence mechanisms involve close interactions between the nervous and immune systems following an immune challenge. The vagal pathways which modulate major visceral functions under normal conditions are also important neural pathways for the transmission of information on peripheral conditions to the CNS.

  7. 5. Autonomic function and myocardial repolarisation. Studies in renal diseases and in spinal cord injury

    Author : Sinsia Gao; Göteborgs universitet; []
    Keywords : vagus; sympathetic nervous system; repolarisation; baroreflex; reproducibility; agreement; hypertension; spinal cord injury; autonomic dysreflexia; renal failure.;

    Abstract : Both experimental and clinical evidence indicates that cardiac parasympathetic markers such as baroreflex sensitivity (BRS) and heart rate variability (HRV) have significant prognostic value. Furthermore, increased myocardial repolarisation lability reflected by increased QT variability index (QTVI) has been identified as a predictor for sudden cardiac death. READ MORE
