| Research Abstract |
It seems critically useful to develop the visible system how the retinal ganglion cells (RGCs) suffer from its damages and proceed into neuropathy under relative high intraocular pressures in vivo, although serious ocular disease like glaucoma, exists itself in optic neuropathy. Therefore we generate cyan fluorescein protein (CFP) expressed Vav2-deficient (CFP/Vav2) mice and Vav2, 3-deficient (CFP/Vav2, 3) mice respectively that only RGCs express CFP in those mice. First, we examined and proved that CFP/Vav2 mice system allows us to evaluate the RGCs damages quantitatively and paternally in vivo on the time course. This innovation is promising because the results obtained from RGCs examination are available for the neural cells of the brain.
