- The aim of the present work was to identify the characteristics of the control of apoptosis in neurosecretory centers of aged (18 months) mice on exposure to the immunomodulator interferon-alpha (IA) in comparison with young (two months) mice. Age-related activation of apoptosis in the supraoptic (SON) and paraventricular (PVN) nuclei was found to be mediated by different pathways and could result from changes in the ratio of synthesis of pro-(Bax) and antiapoptotic (Mcl-1, Bcl-2) molecules. In addition, the apoptosis signal cascade in young mice treated with IA was identical in both nuclei, while in aged mice there were differences between the SON and the PVN.
