Regenerative Medicine as an Approach to Treat Alzheimer's Disease
Share

The authors of this open access paper consider the potential for regenerative medicine to treat Alzheimer’s disease, such as by increasing production of new neurons, or delivering neurons via transplantation. While there has been something of an exodus from the amyloid hypothesis of late, given the litany of failure in clinical trials aiming to reduce amyloid in the brain, it still seems clear that protein aggregates (amyloid and tau) occupy a central position in the progression of neurodegeneration. Spurring greater brain tissue maintenance via generation of neurons is a beneficial goal in and of itself, but as a compensatory treatment, it can’t be enough on its own to turn back neurodegeneration primarily caused by factors such as metabolic waste and chronic inflammation.

Alzheimer’s disease (AD) is a chronic neurodegenerative disorder characterized by progressive cognitive decline. Tremendous efforts have been made to develop novel therapeutics to potentially reverse disease progression. Substantial neuronal loss is observed even in mild AD patients. Intuitively, increasing the number of neurons or replacing lost neurons are potential therapeutic strategies for AD. Stem cells are capable of renewing themselves continuously and differentiating into specialized cells, including neurons.
