Genetic diversity impacts disease severity

New research offers clues as to why some diseases are highly variable between individuals. The phenomenon is apparent in people with retinitis pigmentosa, a condition that causes the light-sensing cells in the eye to degenerate. ...

Scientists deploy CRISPR to preserve photoreceptors in mice

Silencing a gene called Nrl in mice prevents the loss of cells from degenerative diseases of the retina, according to a new study. The findings could lead to novel therapies for preventing vision loss from human diseases ...

Visual pigment rhodopsin forms two-molecule complexes in vivo

The study of rhodopsin—the molecule that allows the eye to detect dim light—has a long and well-recognized history of more than 100 years. Nevertheless, there is still controversy about the structure in which the molecule ...
