Does the autonomic nervous system control the immune system?

Central autonomic neural networks are informed of peripheral immune status via numerous communicating pathways, including neural and non-neural. Cytokines and other immune factors affect the level of activity and responsivity of discharges in sympathetic and parasympathetic nerves innervating diverse targets.

Does the brain control white blood cells?

The brain may not only control our thoughts and basic physical functions. Recent studies indicate that it also controls the way our body responds to the threat of bacterial infections. It does this by boosting the production of a protective molecule called PCTR1 that helps white blood cells kill the invading bacteria.
