title: Purinergic signaling at immunological synapses.
abstract: The early studies and hypotheses of Geoffrey Burnstock catalyzed intensive characterization of roles for nucleotides and P2 nucleotide receptors in neurotransmission and neuromodulation. These latter analyses have focused on the mechanisms of nucleotide release and action in the microenvironments of nerve endings and synapses. However, studies of various white blood cells, such as monocytes, neutrophils, and lymphocytes, suggest that locally released nucleotides also modulate intercellular signaling at so-called 'immunological synapses'. This communication describes recent findings and speculations regarding nucleotide release and signaling in several key phases of the immune and inflammatory responses.
