Neurotransmission of Immune Cells

For decades, the interactions between the peripheral immune system and the brain have played a key role in disease. However, the molecular, biochemical, and cellular interactions that affect neuroimmune responses remain under investigation. Only in the last two decades has it become evident that the neuroimmune axis is reciprocal to maintaining health. When it becomes dysfunctional, it can underline disease pathobiology. This chapter focuses on what is known and what still remains to unravel the neuroimmune axis.
