To define the inflammasome complexes that contribute to IL-1β secretion following infection with virulent IOE and regulated by MyD88, we further analyzed mRNA expression of several inflammasome complexes (NLRP3, NLRC4, AIM2) in the liver tissues of WT and MyD88-/- mice on day 7 p.i with IOE. The gene discussed is MYD88; the disease is infection.
