  • TRPV1 is known to be expressed in peripheral structures and the spinal cord, especially for pain processing. Here the authors show that in the brain, in particular the anterior cingulate cortex, TRPV1 is functionally expressed in microglia; stimulation of TRPV1 activates microglia, which in turn affects glutamatergic neurotransmission.
