Scientists at the Jules Stein Eye Institute at the David Geffen School of Medicine at UCLA have discovered that certain retinal cells can rewire themselves when vision begins to deteriorate in ...

Perfect Vision But Blind To Light Date: June 17, 2008 Source: Salk Institute Summary: Mammals have two types of light-sensitive detectors in the retina. Known as rod and cone cells, they are both ...

Dr. Magdalena Renne, a leading expert in 3D organoid systems, details how her team has overcome longstanding barriers in ...

Here we show that at bright light levels, mouse rods act as relay cells for cone-driven horizontal cell–mediated surround inhibition. In response to large, bright stimuli that activate their ...

Differential composition of DHA and very-long-chain PUFAs in rod and cone photoreceptors. Journal of Lipid Research, 2018; 59 (9): 1586 DOI: 10.1194/jlr.M082495 ...

Rods and cones are cells that line the retina in our eyes. Rods are long and thin, and more sensitive to light than cones. However, cones, which are triangular, allow us to see in color.

In line with these findings, Ait-Ali et al. 12 recently showed that rod-derived cone viability factor promotes cone cell survival by stimulating the glucose uptake and glycolysis.

There’s only about one motion-sensing cell, called an upsilon cell, for every 10,000 rods and cones, he says. This scarcity is the main reason that upsilon cells have been so difficult to discover.

To determine whether Pias3 orchestrates rod cell development, the researchers used mice. First, they engineered mice to make more Pias3 than normal in the eye and counted rod and cone cells. Those ...

Unlike the millions of rod and cone cells imparting vision, melanopsin is only present in roughly 2,000 cells, which are known as melanopsin-expressing retinal ganglion cells or mRGCs. Embedded in ...
