The effect of low-energy laser irradiation on apoptotic factors following experimentally induced transient cerebral ischemia

▶Laser may protect the brain by upregulating Akt, pAkt, pBAD, and Bcl-2 expression following transient cerebral ischemia. ▶Laser may protect the brain by downregulating caspase 9 and caspase 3 expression. ▶The neuroprotective effect of laser appears to be dosage independent.
