GM-CSF AND/OR DEFENSIN PROTEIN EXPRESSION REGULATORS IN EPITHELIAL CELLS COMPRISING ETS TRANSCRIPTION FACTOR OR GENE ENCODING THE SAME

摘要

To solve the problem of drug tolerence and side effects in antiinflammatory agents, immunosuprressive agents and antiviral agents having been put into practical use, it is intended to provide a novel therapy for inflammation and novel antiinflammatory agents with the use of an ETS transcription factor which regulates the gene expression of an inflammartory cytokine GM-CSF and a bactericidal peptide beta -defensin. Namely, expression regulators for the inflammatory cytokine GM-CSF and /or beta -defensin in epithelial cells and antiinflammatory agents which comprise an ETS transcription factor having a gene transcription regulatory activity or a gene encoding the same, or a substance regulating the function of ETS transcription factor or a gene encoding the same, more specifically, a transcription regulatory protein myeloid Elf-1 like factor (MEF) or a gene encoding the same, or a substance regulating the function of the MEF protein or a gene encoding the same. More specifically, inflammatory cytokine GM-CSF production inhibitors, and /or regulators for beta -defensin expression due to overexpression, and antiinflammatory agents.
