cells communication found immune involving normally novelty potential reveal
The novelty is that we reveal a potential communication, involving the transmitter serotonin, between immune cells that is normally only found between neurons.
addition additional appears behind cells entirely immune machinery physical point surprised
In addition to the physical contact, it surprised us to find that these immune cells also have machinery to take up serotonin and to secrete it in an excitatory manner. The point behind this transmission is not entirely clear, but it appears to be an additional way of stimulating a T cell response.
commonly health immune impact target wider
The wider health implication is that commonly used SSRI antidepressants, which target the uptake of serotonin into neurons, may also impact the uptake in immune cells.
