Over the past 5 years, experimental data have emerged that ischemia-induced cell death pathways may differ in males and females. Cell death in males is triggered by poly(ADP-ribose) polymerase activation and nuclear translocation of apoptosis-inducing factor. We have previously shown

The present study evaluated whether nuclear factor-kappaB (NF-kappaB) activation contributes to the apoptotic-like death of striatal neurons induced by kainic acid (KA) receptor stimulation. Intrastriatally infused KA (1.25-5.0 nmol) produced substantial neuronal loss as indicated by an 8-73% decrease in
