Bile acid inhibits cell death in Huntington's disease

Researchers discovered that tauroursodeoxycholic acid (TUDCA) can cross the blood-brain barrier and reduce apoptosis in mice with the HD gene, improving neurological cell function. The bile acid's anti-apoptotic qualities may also have potential for treating other chronic neurodegenerative conditions.

Adult stem cells selectively delivered into the eye and used to control angiogenesis at TSRI

Researchers at TSRI have developed a technique to selectively deliver adult stem cells into the eye, which can stimulate vessel growth and address inherited retinal degenerations. The cells can incorporate into the vasculature and make it normal, or be loaded with antiangiogenics to selectively wipe out the formation of new blood vessels.
