Targeting protein kinase C-α prolongs survival and restores liver function in sepsis: Evidence from preclinical models by Ling Xiong, Dustin Beyer, Na Liu, Tina Lehmann, Sophie Neugebauer, Sascha Schaeuble, Oliver Sommerfeld, Philipp Ernst, Carl-Magnus Svensson, Sandor Nietzsche, Sebastian Scholl, Tony Bruns, Nikolaus Gaßler, Markus H. Gräler, Marc Thilo Figge, Gianni Panagiotou, Michael Bauer, Adrian T. Press

“…Using a preclinical murine sepsis model, we found that both PKCα knockout and the use of a PKCα-inhibitor midostaurin successfully restored liver function without hindering the host’s response or ability to clear the pathogen, highlighting PKCα’s vital role in excretory liver failure. …”
