Innate Immune Signaling Organelles Display Natural and Programmable Signaling Flexibility.

ABSTRACT: The signaling organelles of the innate immune system consist of oligomeric protein complexes known as supramolecular organizing centers (SMOCs). Examples of SMOCs include myddosomes and inflammasomes, which respectively induce transcription-dependent and -independent inflammatory responses. The common use of oligomeric structures as signaling platforms suggests multifunctionality, but each SMOC has a singular biochemically defined function. Here, we report that the myddosome is a multifunctional organizing center. In addition to promoting inflammatory transcription factor activation, the myddosome drives the rapid induction of glycolysis. We identify the kinase TBK1 as a myddosome component that promotes glycolysis, but not nuclear factor κB (NF-κB) activation. Synthetic immunology approac
