Recent studies indicate impaired calcium regulation of striatal neurons in Huntington's disease, due to excessive activation of the neuronal store-controlled calcium entry in this cell type, which leads to the elimination of synaptic connections between neurons of the cortex and striatum. In the present work, it has been demonstrated that activation of the sigma 1 receptor by a selective agonist decreases the activity of store-controlled calcium entry in striatal neurons, which in turn prevents dendritic spine loss in a cellular model of Huntington's disease. Thus, the sigma 1 receptor can be considered as a therapeutic target for the treatment of Huntington's disease.
