Sigma receptors, particularly the sigma-1 receptor subtype, which are expressed in both neurons and glia of multiple regions within the central nervous system, are a unique class of intracellular proteins that can modulate many biological mechanisms associated with neurodegeneration.  Therefore the sigma-1 receptor is attracting great interest as a potential target for neuroprotective treatments. Now, researchers from the Georgia Regents University report the sigma-1 receptor also … Continue reading Neuroprotective receptor found to have important role in support cells for the retina.
