Journal ArticleDOI
Neurotoxic reactive astrocytes are induced by activated microglia
Shane A. Liddelow,Kevin A. Guttenplan,Laura E. Clarke,Frederick C. Bennett,Christopher J. Bohlen,Lucas Schirmer,Mariko L. Bennett,Alexandra E. Münch,Won-Suk Chung,Todd C. Peterson,Daniel K. Wilton,Arnaud Frouin,Brooke A. Napier,Nikhil Panicker,Manoj Kumar,Marion S. Buckwalter,David H. Rowitch,Valina L. Dawson,Ted M. Dawson,Beth Stevens,Ben A. Barres +20 more
TL;DR: It is shown that activated microglia induce A1 astrocytes by secreting Il-1α, TNF and C1q, and that these cytokines together are necessary and sufficient to induce A2 astroCytes, which are abundant in various human neurodegenerative diseases.
Journal ArticleDOI
Block of A1 astrocyte conversion by microglia is neuroprotective in models of Parkinson's disease

TL;DR: It is found that NLY01 is a potent GLP1R agonist with favorable properties that is neuroprotective through the direct prevention of microglia-mediated conversion of astrocytes to an A1 neurotoxic phenotype and should be evaluated in the treatment of Parkinson’s disease and related neurologic disorders characterized by microglial activation.

A disk access method for delivering multimedia and video information on demand over wide area networks
Jack L. Kouloheris,Manoj Kumar +1 more
TL;DR: In this paper, the disks in the array are accessed simultaneously so that at any given instance, different disks are accessing the video or multimedia data for different streams, and access to the disks for reading the continuous media files is scheduled periodically, with the period equal to the back time of the stripes.
Journal ArticleDOI
Ribosomal protein s15 phosphorylation mediates LRRK2 neurodegeneration in Parkinson's disease.
Ian Martin,Jungwoo Wren Kim,Byoung Dae Lee,Ho Chul Kang,Jinchong Xu,Hao Jia,Jeannette N. Stankowski,Min-Sik Kim,Jun Zhong,Manoj Kumar,Shaida A. Andrabi,Yulan Xiong,Dennis W. Dickson,Zbigniew K. Wszolek,Akhilesh Pandey,Ted M. Dawson,Valina L. Dawson +16 more
TL;DR: It is shown that ribosomal protein s15 is a key pathogenic LRRK2 substrate in Drosophila and human neuron PD models and can be prevented by phosphodeficient T136A s15, revealing a novel mechanism of PD pathogenesis linked to elevated L RRK2 kinase activity and aberrant protein synthesis in vivo.
Proceedings ArticleDOI
Mathematical foundations of the GraphBLAS
Jeremy Kepner,Peter Aaltonen,David A. Bader,Aydin Buluc,Franz Franchetti,John R. Gilbert,Dylan Hutchison,Manoj Kumar,Andrew Lumsdaine,Henning Meyerhenke,Scott McMillan,Carl Yang,John D. Owens,Marcin Zalewski,Timothy G. Mattson,José E. Moreira +15 more
TL;DR: The GraphBLAS standard as discussed by the authors defines a core set of matrix-based graph operations that can be used to implement a wide class of graph algorithms in a wide range of programming environments.
