Expression and localization of Nedd2/ICH-1 (caspase-2) were examined in the developing rat retina. The expression of Nedd2 mRNA was conspicuous in the prenatal period and down-regulated in the postnatal period. In contrast, the expression of an alternatively spliced form of Nedd2 encoding a truncated protein, which has been shown to protect against programed cell death (PCD), was faint in the prenatal period but increased gradually in the postnatal period. Nedd2 immunoreactivity was observed in almost all cells of the ganglion cell layer (GCL) during the perinatal period, when some nuclei in the GCL showed pyknosis or fragmentation. Nedd2-positive cells in the neuroblastic layer (NBL) were present in patches at embryonic day 19, and began to assume a stratified arrangement at postnatal day 3, when nuclei showing PCD were observed in places across the NBL. At postnatal day 14, only faint Nedd2 immunoreactivity was observed in the GCL and the inner nuclear layer, and no Nedd2 immunoreactivity was present in the outer nuclear layer. These findings demonstrate the cell type- and differentiation-specific patterns of the Nedd2 expression in the developing retina.
