Harnessing serotonergic and dopaminergic pathways for lymphoma therapy: evidence and aspirations.

Growing evidence supports the notion that pharmaceutical targeting of the 5-hydroxytryptamine (5-HT) and dopamine (DA) systems offers the potential to treat human immune system disorders. This review describes this emerging area of research, which has the benefit of being supported by a relatively detailed understanding of these monoamine systems within other tissues of the body. Furthermore, the availability of a number of pharmaceutical agents originally developed to manipulate central monoamine function, offer many suitable drug candidates to test their therapeutic potential in the immune pathology arena.
