Activation1

  • Queuosine modification may separate antimicrobial protection from inflammatory damage

    Where this hypothesis actsMyeloid descendants of blood-forming stem cells with inflammatory memory before repeated infections

    What is proposedRestore tRNA queuosine modification

    With whatNot stated in the record

    HowAlter QTRT1/QTRT2 complex activity; the record also proposes that environmental queuine availability sets the modification state in newly formed cells

    Possible resultPossible reduction in chronic inflammatory transcription while preserving rapid synthesis of protective proteins
