Regulation of Immunoproteasome Subunit Expression In Vivo Following Pathogenic Fungal Infection

Abstract excerpt

The proteasome catalytic beta subunits LMP2, LMP7, and MECL-1 and two proteasome activator proteins, PA28 alpha and beta, are induced following exposure to IFN-gamma in vitro. Induction of these immunosubunits and the PA28 alpha/beta hetero-oligomer alters proteasome catalytic functions and specificity and enhances production of certain MHC class I epitopes. We sought to determine whether and to what extent...
