Treatment of stroke and intracerebral hemorrhage with cellular and pharmacological restorative therapies.
We describe some of our studies on use of neuro-restorative agents for treatment of neural injury. We focus on cell-based therapies and select from a variety of statins. In addition, we show that cell-based and pharmacological-based therapies enhance brain plasticity and promote recovery of function after stroke and intracerebral hemorrhage (ICH). Injured brain recapitulates ontogeny. Cerebral tissue around the infarction expresses developmental genes, many of which are present only during embryonic or neonatal stages of development. Brain response to injury undergoes remodeling with induction of angiogenesis, neurogenesis, and synaptogenesis. The attempt at remodeling, although expressed as a partial improvement in patients with stroke and ICH, is clearly insufficient to promote substantial recovery in many patients. The goal of restorative therapies should be to activate and amplify this endogenous restorative brain plasticity process to potentiate functional recovery. The logic of restorative therapy is to treat intact or marginally compromised tissue and not injured or dying tissue. Thus, these treatments can be made available for all neurological injury. Once demonstrated to be effective for treatment of a large middle cerebral artery occlusion (MCAo), these restorative treatments can be applied to many types of injury, including ICH, traumatic brain injury, and neurodegenerative disease such as experimental autoimmune encephalomyelitis and multiple sclerosis.
