DEEP DIVE · CHAPTER 13
The Immune Messenger
Yes, dopamine acts on the immune system. It is a messenger between immune cells, not only between nerve cells.
I filed this work away as a curiosity the first time I read it, and I was wrong. Every one of your white blood cells carries dopamine receptors, and they build the molecule themselves. Here is what that conversation does in real disease, and the one cheap blood test I can order this week because of it.

Frequently asked questions
Does dopamine affect the immune system?
Yes. Dopamine acts on the immune system. It is a messenger between immune cells, not only between nerve cells. Dr. Padda filed this work away as a curiosity the first time he read it, and says he was wrong. Chapter 13 of The Dopamine Brain explains what that conversation does in real disease.
Do white blood cells have dopamine receptors?
Yes. Every one of your white blood cells carries dopamine receptors, and they build the molecule themselves. That means dopamine is not only a brain chemical. The Chapter 13 Deep Dive sets out the 20 verified references behind this, who was in each study, and what each study does not show.
Is there a blood test connected to dopamine and immunity?
Yes. Because white blood cells carry dopamine receptors and make dopamine themselves, Dr. Padda points to one cheap blood test he can order this week because of this research. The Chapter 13 Deep Dive covers it, and it is written to be shared with your own physician, along with the questions to bring to that visit.
