We provide evidence that cocaine induces sigma-1 receptor-mediated inhibition of store-operated calcium entry (SOCE) in rat brain microvascular endothelial cells. Thus, we reveal sigma-1 receptors as SOCE blockers, adding novel insight regarding endothelial effects of cocaine and endogenous SOCE modulation.
