Neurotensin attenuates dopamine D2 agonist quinpirole-induced inhibition of midbrain dopamine neurons.

abstract：:Painful nerve injury disrupts Ca2+ signaling in primary sensory neurons by elevating plasma membrane Ca2+-ATPase (PMCA) function and depressing sarco-endoplasmic reticulum Ca2+-ATPase (SERCA) function, which decreases endoplasmic reticulum (ER) Ca2+ stores and stimulates store-operated Ca2+ entry (SOCE). The extracell...

abstract：:Recent evidence suggests an early involvement of dopaminergic (DA) processes and terminals in Parkinson's disease (PD). The arborization of neurons depends on the actin cytoskeleton, which in turn is regulated by small GTPases of the Rho family, encompassing Rho, Rac and Cdc42 subfamilies. Indeed, some reports point t...
