Download: Nerve cell death, by either necrosis or apoptosis, is a common feature of many neurological diseases including AIDS-associated dementia and Alzheimer's disease. The roles of adenosine triphosphate (ATP) in the induction of apoptosis are well established. However, the possible role of adenosine diphosphate (ADP) in cell death induction has not been studied. We have shown that ATP is an effective inducer of necrosis in human peripheral blood lymphocytes (HPBL) and in the human neuroblastoma cell line BE(2)C, but that ADP is significantly less effective. This observation has been extended to the RBL-2H3 mast cell line, where ADP-induced necrosis was found to be mediated by the P2Y12 receptor. In addition, we have found that the P2X1 receptor mediates a non- apoptotic form of cell death in BE(2)C cells. Our preliminary data also show that the P2X7 receptor mediates ADP-induced apoptosis in HPBL. The molecular mechanisms underlying the roles of ATP and ADP in cell death induction are not well defined. We propose to characterize further the apoptotic and necrotic mechanisms induced by ADP and ATP in lymphocytes and mast cells. We will test the hypothesis that the effect of ADP on cell death is mediated by ADP receptors other than P2Y12. We will determine the involvement of the P2X1 receptor, the P2X7 receptor, or both receptors in ADP-induced apoptosis and necrosis. We will also determine the involvement of phosphatidylinositol 3 kinase (PI3K), phosphatase and tensin homologue deleted on chromosome 10 (PTEN) or Akt in ADP-induced apoptosis and necrosis. Finally, we will determine whether the necrotic responses in mast cells and HPBL are mediated by PI3K, Akt, or a protein kinase C-like kinase. In addition, we will determine the roles of cysteine proteases, high-molecular-weight neurofilament proteins and NADPH oxidase in ADP-induced apoptosis and necrosis in mast cells and in HPBL. The proposed studies will provide new information on the molecular mechanisms involved in ADP-induced cell death. These studies will also help identify novel targets in the treatment of neurological diseases associated with
