As part of theADVANCE Distinguished Lecture Seriesand theDivision of Biology SeminarSeries, Mary O'Riordan, professor of microbiology and immunology at the 1xbet best casino website of Michigan, will present "STRESSing Out Over Infection — How Cellular Stress Shapes Innate Immunity" at 3:30 p.m. Monday, Oct. 25, in 221 Ackert Hall.
Innate immune cells are wired to sense danger and 1xbet best casino website , using existing organelle 1xbet best casino website circuits to amplify pro-inflammatory signaling. We explore mechanisms of innate immune responses to bacterial infection, focusing on 1xbet best casino website sensing and signaling in the ER, mitochondria and cytosol. Our previous studies have identified the ER 1xbet best casino website sensor IRE1 as a critical regulator of macrophage and neutrophil innate immune signaling. Moreover, IRE1 acts to control pro-inflammatory through multiple pathways, including programming mitochondrial 1xbet best casino website . Infection or Toll-like receptor engagement signals profound changes in mitochondrial metabolism, signaling and architecture. Our current studies are elucidating the contribution of key mitochondrial components, such as the phospholipid cardiolipin, to switching mitochondrial function from homeostasis to supporting pro-inflammatory signaling. Collectively, our data support a model where regulators of ER and mitochondrial 1xbet best casino website shape and scaffold the innate immune response to infection.
