Necrotic cell death and neurodegeneration
Necrosis, one of the two main types of cell death, contributes critically in many devastating pathological conditions in human, including stroke, ischemia, trauma and neurodegenerative diseases. However, unlike apoptosis, the molecular mechanisms underlying necrotic cell death and neurodegeneration are poorly understood. Caenorhabditis elegans offers a powerful platform for a thorough and syste...
متن کاملProblems of cell death in neurodegeneration and Alzheimer's Disease.
Progressive cell loss in specific neuronal populations is a pathological hallmark of neurodegenerative diseases, but its mechanisms remain unresolved. Apoptosis or alternative pathways of neuronal death have been discussed in Alzheimer disease (AD) and other disorders. However, DNA fragmentation in human brain as a sign of neuronal injury is too frequent to account for the continuous loss in th...
متن کاملNeurodegeneration in Lurcher mice occurs via multiple cell death pathways.
Lurcher (Lc) is a gain-of-function mutation in the delta2 glutamate receptor (GRID2) that results in the cell-autonomous death of cerebellar Purkinje cells in heterozygous lurcher (+/Lc) mice. This in turn triggers the massive loss of afferent granule cells during the first few postnatal weeks. Evidence suggests that the death of Purkinje cells as a direct consequence of GRID2(Lc) activation an...
متن کاملMolecular basis of programmed cell death involved in neurodegeneration.
Rapid progress in understanding the molecular basis of neurodegeneration has been tightly linked with recent discoveries in the field of programmed cell death (PCD). Analysis of PCD in neuronal demise has led to identification of several associated phenomena, such as re-initiation of the cell cycle and the key role of oxidative stress, although putative causal relationships between these events...
متن کاملMitochondrial dynamics in neurodegeneration: from cell death to energetic states
From Parkinson’s disease to an ischemic stroke, a consistently reoccurring theme in the context of neuronal degeneration is the dysfunction of mitochondria as the underlying factor. Insight into the mechanistic basis for mitochondrial dysfunction in neurodegenerative disorders has allowed the theme of mitochondrial dynamics to be highlighted as a central player. The precise balance of mitochond...
