Retinitis Pigmentosa :: Green Algae may be helpful in retinitis pigmentosa

Nerve cells that normally are not light sensitive in the retinas of blind mice can respond to light when a green algae protein called channelrhodopsin-2 (ChR2) is inserted into the cell membranes, according to a National Institutes of Health (NIH)-supported study published in the April 6, 2006 issue of the journal Neuron. The study was conducted with mice that had been genetically bred to lose rods and cones, the light-sensitive cells in the retina. This condition is similar to the blinding disease retinitis pigmentosa (RP) in humans.
