How does mind affect the Immune System?

As an immunologist and student of psychology I summarize the mind-body connection as follows:

We are born with a genetic tendency to perceive life-events differently.
Perception is influenced by our past experience (child abuse etc.). Stressors affect the limbic system – the emotional part of the brain. That leads to activation of autonomic system (increased heart, diarrhea, sweating, head ache etc.).
Increased stressors lead to increased production of cortisol, and adrenalin etc.
Increased chronic cortisol levels lead to decreased immune function (recurrent colds etc.,)
Increased stressors diminish DNA duplication of nerve cells of a certain part of the brain – hippocampus and atrophy of that part of the brain.

We need duplication of DNA to produce dopamine etc. to prevent depression.
Reduced levels of dopamine and other neurochemicals lead to diminished cognitive abilities and reduced memory and depression.

We need normal mind for normal function of the body!
