Cop-1-reactive T cells protect RGCs from glutamate toxicity.
Immediately after injection of glutamate (200 nmol), mice were injected
with Cop-1-reactive T cells or with PBS. Dye application, preparation,
and counting of RGCs and calculation of RGC survival were as described
for Fig. 1. Significantly more labeled RGCs were seen in the retinas of
mice injected with Cop-1-reactive T cells than in the retinas of
PBS-injected control mice (**, P <
0.0007, Student's t test).
