Effect of genetic depletion of 11-cis-retinal production (Lrattm1Kpal/Lrattm1Kpal) on retinal degeneration in Rhotm1.1Kpal/Rho+ mice

vision/eye
decreased retina photoreceptor cell number ( J:170648 )
• dramatically reduced at P36
abnormal retina rod cell outer segment morphology ( J:170648 )
• less than in Rhotm1.1Kpal heterozygotes
retina photoreceptor degeneration ( J:170648 )
• due to increased apoptosis
retina rod cell degeneration ( J:170648 )
• less than in Rhotm1.1Kpal heterozygotes

nervous system
