Activation of the Brain-Splenic Nerve Axis in Hypertension: The Cholinergic-Sympathetic-Immune System Connection

Activation of the Brain-Splenic Nerve Axis in Hypertension: The Cholinergic-Sympathetic-Immune System Connection

A recent Nature Communications study indicates that hypertension is linked to T cell activation and an egression of T-cells from the spleen, and that this process is dependent on a vagus-splenic nerve connection. Hypertension is a major risk factor for coronary heart diseases and stroke. Despite various therapeutic approaches 10-15% of the general hypertensive population […]

Influence of the Sympathetic Nervous System on Regulatory T cells: Another Link in Neuro-Immune Interactions

Influence of the Sympathetic Nervous System on Regulatory T cells: Another Link in Neuro-Immune Interactions

OVERVIEW ARTICLE Homeostatic control of the immune system is dependent on CD4, FoxP3+, NKT or antigen-specific CD4+ or CD8+ regulatory T cells. These regulatory T cells are essential to prevent or mitigate autoimmunity and the immune response to non-self antigens. Herein is an overview of our observations on the inhibition of the induction of splenic […]
