How is the membrane protein folded?

A key factor in the biosynthesis and stable expression of multi-pass transmembrane proteins was discovered, and its loss is thought to cause retinal degeneration. The factor works especially for multi-pass membrane proteins, ...

Nanotubes may restore sight to blind retinas

The aging process affects everything from cardiovascular function to memory to sexuality. Most worrisome for many, however, is the potential loss of eyesight due to retinal degeneration.

Artificial retina could someday help restore vision

The loss of eyesight, often caused by retinal degeneration, is a life-altering health issue for many people, especially as they age. But a new development toward a prosthetic retina could help counter conditions that result ...

Japan govt approves stem cell clinical trials

Japan's government on Friday gave its seal of approval to the world's first clinical trials using stem cells harvested from a patient's own body.

Scientists model human disease in stem cells

Many scientists use animals to model human diseases. Mice can be obese or display symptoms of Parkinson's disease. Rats get Alzheimer's and diabetes.

Japan researchers close in on stem cell trial

Researchers in Japan have moved one step closer to clinical trials using adult stem cells in a therapy they hope will prove a cure for common sight problems, an official said Thursday.

Nanoparticles help researchers deliver steroids to retina

Hitching a ride into the retina on nanoparticles called dendrimers offers a new way to treat age-related macular degeneration and retinitis pigmentosa. A collaborative research study among investigators at Wayne State University, ...

Melanopsin looks on the bright side of life

Better known as the light sensor that sets the body's biological clock, melanopsin also plays an important role in vision: Via its messengers-so-called melanopsin-expressing retinal ganglion cells, or mRGCs-it forwards information ...
