Task: Question Generation
Input (English): Experimental autoimmune encephalomyelitis (EAE) is an animal model of autoimmune inflammatory demyelination that is mediated by Th1 and Th17 cells. The transcription factor interferon regulatory factor 3 (IRF3) is activated by pathogen recognition receptors and induces interferon-β production.', 'To determine the role of IRF3 in autoimmune inflammation, we immunised wild-type (WT) and irf3(-/-) mice to induce EAE. Splenocytes from WT and irf3(-/-) mice were also activated in vitro in Th17-polarising conditions.', 'Clinical signs of disease were significantly lower in mice lacking IRF3, with reduced Th1 and Th17 cells in the central nervous system. Peripheral T-cell responses were also diminished, including impaired proliferation and Th17 development in irf3(-/-) mice. Myelin-reactive CD4+ cells lacking IRF3 completely failed to transfer EAE in Th17-polarised models as did WT cells transferred into irf3(-/-) recipients. Furthermore, IRF3 deficiency in non-CD4+ cells conferred impairment of Th17 development in antigen-activated cultures.
Output (English): Is interferon regulatory factor ( IRF ) 3 critical for the development of experimental autoimmune encephalomyelitis?
