Apoptosis as a Potential Target in Therapeutic and Vaccine Interventions against Parasitic Diseases
Apoptosis is a physiological cell death that occurs under normal conditions in major biological processes, including the removal of old, damaged, extra, or harmful cells. It plays an important role in natural evolution, tissue homeostasis, removal of cells damaged or infected by viruses, and removal of immune cells activated against self-antigens. The purpose of this review was to examine the r...
متن کاملOverexpressed cyclophilin A in cancer cells renders resistance to hypoxia- and cisplatin-induced cell death.
Cyclophilin A (CypA) has been reported to be overexpressed in cancer cells, especially in solid tumors. To determine the role of CypA in tumorigenesis, we investigated the induction of CypA as well as the role it plays in cancer cells. Here, we have shown that induction of CypA is associated with hypoxia in a variety of cells, including DU145 human prostate cancer cell line. Our analysis of the...
متن کاملApoptosis-inducing factor is involved in the regulation of caspase-independent neuronal cell death
Caspase-independent death mechanisms have been shown to execute apoptosis in many types of neuronal injury. P53 has been identified as a key regulator of neuronal cell death after acute injury such as DNA damage, ischemia, and excitotoxicity. Here, we demonstrate that p53 can induce neuronal cell death via a caspase-mediated process activated by apoptotic activating factor-1 (Apaf1) and via a d...
متن کاملO 3:Therapeutic Potential of a Novel NMDA Receptor Subunit 2B Antagonist in a Mouse Model of Autoimmune Neuroinflammation
Glutamate-mediated excitotoxicity and neurodegeneration have been shown as pathophysiological hallmarks of multiple sclerosis (MS) and other autoimmune inflammatory CNS disorders. N‑Methyl‑D‑Aspartate (NMDA) receptors play a pivotal role in the mediation of neuronal glutamate excitotoxicity leading to cellular damage and apoptotic cell death. Current treatment approaches targeting glutamate exc...
متن کاملCyclophilin A participates in the nuclear translocation of apoptosis-inducing factor in neurons after cerebral hypoxia-ischemia
Upon cerebral hypoxia-ischemia (HI), apoptosis-inducing factor (AIF) can move from mitochondria to nuclei, participate in chromatinolysis, and contribute to the execution of cell death. Previous work (Cande, C., N. Vahsen, I. Kouranti, E. Schmitt, E. Daugas, C. Spahr, J. Luban, R.T. Kroemer, F. Giordanetto, C. Garrido, et al. 2004. Oncogene. 23:1514-1521) performed in vitro suggests that AIF mu...
