Rb-deficient mice produce more type I IFN with resistance to virus infection.
Rb selectively inhibits the innate IFN-β production in macrophages.
Rb binds Ifnb1 enhancer region through c-Jun and suppresses Ifnb1 gene transcription.
Rb recruits HDAC1 and HDAC8 to Ifnb1 promoter to induce histone H3/H4 deacetylation
