Neuroprotection by salubrinal treatment in global cerebral ischemia

Most common cerebrovascular accidents （CVAs） result from the occlusion of a blood vessel and are called ischemic stroke. The interruption of the blood flow reduces the oxygen and glucose levels in the neural pareuchyma, which in turn decreases the energy of the cells and compromises their homeostasis. This condition has to be reverted for cell survival. One of the homeostatic processes impaired by cerebral ischemia is protein folding in the endoplasmic reticulum （ER） lumen where unfolded proteins are accumulated （Degracia and Monti, 2004）. This situation, known as ER stress, elicits the so called unfolded protein response （UPR）,
