detected within the nucleus 1 h after reperfusion and 45 min
of MCAo. AIF translocation synchronized with cytochrome c
release from mitochondria and preceded cell death as
indicated by apoptosis-related DNA fragmentation (Plesnila
et al., 2004). Further, microinjection of neutralizing antibodies
against AIF significantly decreased injury-induced neuronal
cell death in Apaf1-deficient neurons (Cregan et al., 2002) and
Harlequin mice, which bear a hypomorphic AIF mutation,
have reduced expression of AIF (Klein et al., 2002). Further
research on mechanism of caspase-independent cell death
may reveal novel therapeutic targets for the treatment of
stroke (Cregan et al., 2004).
