A Non-canonical Role for Hepatocyte MLKL in Promoting Mitochondrial Dysfunction and Senescence in the Aging Liver

Sabira Mohammed, Chao Jiang, Travis Pennington, Shylesh Bhaskaran, Phoebe Ohene-Marfo, Kara F. Kneuper, Constantin Georgescu, Kamille Pitts, Albert Tran, Zongkai Peng, Amit Singh, Zhibo Yang, Tiangang Li, Bethany N. Hannafon, Courtney W. Houchen, , Sathyaseelan S. Deepa

This study shows that MLKL in hepatocytes promotes liver aging by inducing senescence and mitochondrial dysfunction without causing necroptosis.

Fis1 is required for the development of the dendritic mitochondrial network in pyramidal cortical neurons

Klaudia Strucinska, Parker Kneis, Travis Pennington, Katarzyna Cizio, Patrycja Emanuela Szybowska, Abigail Morgan, Joshua Weertman, Tommy L. Lewis

This study shows Fis1 depletion reduces dendritic mitochondrial length and alters mitochondrial function, leading to increased calcium levels and changes in dendritic branching and spine density.
