KITLG and infection: Consistent with these results, TUNEL assays showed a cell death rate of 40.6 ± 8.2% in Kit+/+ albino mice and 78 ± 11.4% in KitWps/Wps albino mice (n = 4) after control infection, while infection with AAV8-KITL significantly reduced the death rate of photoreceptor cells to 8.9 ± 2.1% in Kit+/+ albino mice but not in KitWps/Wps albino mice, where it remained high (75.9 ± 8.2%, n = 4) (Figure 4H,J).
