Untangling Alzheimer’s Disease — DNA Damage in Alzheimer’s

Drs. Hyundong Song and Yujun Hou, standing together here in their lab, are postdoctoral fellows working to find ways that doctors may one day effectively treat Alzheimer’s disease.

Given that Alzheimer’s is such a complex disease with many causes and pathways, it is not surprising that the search for effective treatments has proven difficult. So I spoke with Drs. Yujun Hou and Hyundong Song, postdoctoral fellows in the IRP’s Laboratory of Molecular Gerontology at the National Institute on Aging (NIA) to learn more about their approaches to meeting the challenge.

Exercise Releases Brain-Healthy Protein

Five images of different exercise activities

We all know that exercise is important for a strong and healthy body. Less appreciated is that exercise seems also to be important for a strong and healthy mind, boosting memory and learning, while possibly delaying age-related cognitive decline. How is this so? Researchers have assembled a growing body of evidence that suggests skeletal muscle cells secrete proteins and other factors into the blood during exercise that have a regenerative effect on the brain.

Neuronal Trees in Holiday Colors

These may remind you of trees on a winter day, but they are brain neurons grown in a special chamber that separates axons from dendrites.
