COMMENT Evidence exists that cell death seen in AD arises from neurons attempting to divide, and this is why researchers working in the field believe that AD therapy might benefit from drugs able to arrest cell division in neurons. Until this paper by Varvel and ...
COMMENT This paper by He and Shen is of great interest for several reasons. The first is that the authors address the link between neurogenesis and Alzheimer disease (AD) by studying the cell fate of neural progenitors isolated from AD autopsy specimens. The ...
COMMENT By using the p25 transgenic model of neurodegeneration, Kim and colleagues provide convincing evidence that DNA breakage and cell cycle reactivation coexist prior to neuronal death. New in the study is the demonstration that the underlying link between ...
COMMENT This interesting paper continues the series of studies suggesting that cell cycle reactivation in neurons is causally related to death. Hoeglinger and colleagues show that the injection of MPTP into mice, or the application of MPP+ to dopaminergic neurons ...
COMMENT Surely, the paper by Khurana et al. supports the hypothesis that cell cycle reactivation in postmitotic neurons leads to death. In particular, the paper shows that 1. tau-induced neurodegeneration in Drosophila is partially prevented by cell cycle ...
COMMENT The canonical Wnt signaling pathway has multiple roles in stem/progenitor cells. In embryonic stem cells, activation of Wnt promotes self-renewal and inhibits neural differentiation (1,2). In the central nervous system, Wnt3a is required for neural ...
COMMENT Cell Cycle Signaling, DNA Damage and Neuronal Apoptosis Three years ago, following an extensive review of the literature, my colleagues and I came to a hypothetical model on the relationship among cell cycle signaling, DNA damage, and neuronal apoptosis ...
