Journal ArticleDOI
The PINK1 p.I368N mutation affects protein stability and ubiquitin kinase activity
Maya Ando,Fabienne C. Fiesel,Roman Hudec,Thomas R. Caulfield,Kotaro Ogaki,Paulina Górka-Skoczylas,Dariusz Koziorowski,Andrzej Friedman,Li Chen,Valina L. Dawson,Ted M. Dawson,Guojun Bu,Owen A. Ross,Zbigniew K. Wszolek,Wolfdieter Springer +14 more
TL;DR: It is demonstrated that mutant PINK1 p.I368N can not be stabilized on the OMM upon mitochondrial stress and due to conformational changes in the active site does not exert kinase activity towards Ub, highlighting potential strategies for future drug development.
Journal ArticleDOI
Neuroprotective FK506 Does Not Alter In Vivo Nitric Oxide Production During Ischemia and Early Reperfusion in Rats
Thomas J. K. Toung,Anish Bhardwaj,Valina L. Dawson,Ted M. Dawson,Richard J. Traystman,Patricia D. Hurn +5 more
TL;DR: These data demonstrate that FK506 provides robust neuroprotection against transient focal cerebral ischemia in the rat, and the mechanism of protection in vivo is not through attenuation of ischemic-evoked NO production during MCAO and early reperfusion.
Journal ArticleDOI
Conditional expression of Parkinson's disease-related R1441C LRRK2 in midbrain dopaminergic neurons of mice causes nuclear abnormalities without neurodegeneration
Elpida Tsika,Meghna Kannan,Caroline S. Foo,Dustin Dikeman,Liliane Glauser,Sandra Gellhaar,Dagmar Galter,Graham Knott,Ted M. Dawson,Valina L. Dawson,Darren J. Moore,Darren J. Moore +11 more
TL;DR: Conditional transgenic mice that selectively express human R1441C LRRK2 in dopaminergic neurons from the endogenous murine ROSA26 promoter reveal altered dopamine neuronal morphology with advancing age, and provide a useful tool for exploring the pathogenic mechanisms underlying the R14 41C L RRK2 mutation in PD.
Journal ArticleDOI
Nanozyme scavenging ROS for prevention of pathologic α-synuclein transmission in Parkinson’s disease
Yu Qing Liu,Yuanyang Mao,Enquan Xu,Huimin Jia,Shu Zhang,Valina L. Dawson,Ted M. Dawson,Yan-Mei Li,Zhi Zheng,Weiwei He,Xiaobo Mao +10 more
TL;DR: It is the first time to observe nanozyme can block prion-like spreading, which provides a proof of concept for nanozyme therapy, and it is anticipated that the biomedical application of nanozyme against prional spreading could be optimized and considered to be developed as a therapeutic strategy against Parkinson’s disease, Alzheimer's disease, and other prions-like proteinopathies.
Journal ArticleDOI
The cell biology of Parkinson’s disease
TL;DR: Parkinson's disease (PD) is a progressive neurodegenerative disorder resulting from the death of dopamine neurons in the substantia nigra pars compacta as discussed by the authors, which can cause monogenetic PD when mutated.
