Pharmacological properties of homomeric and heteromeric pannexin hemichannels expressed in Xenopus oocytes

Several new findings have emphasized the role of neuron‐specific gap junction proteins (connexins) and electrical synapses in processing sensory information and in synchronizing the activity of neuronal networks. We have recently shown that pannexins constitute an additional family of proteins that can form gap junction channels in a heterologous expression system and are also widely expressed in distinct neuronal populations in the brain, where...
