Function preservation2

  • Carbamylation may turn protective cathelicidins into tissue-damaging molecules

    Where this hypothesis actsHaematopoietic stem cell inflammatory memory before repeated infectious episodes

    What is proposedPreserve protective memory while limiting cathelicidin carbamylation

    With whatNot stated in the record

    HowKeep memory intact while restricting the subsequent chemical modification of its peptide products

    Possible resultPossible retention of antimicrobial protection with less tissue damage

  • Interleukin-6 from blood-forming stem cells may sustain organ damage while preserving defense

    Where this hypothesis actsDescendants of hematopoietic stem cells with inflammatory memory, during repeated infection episodes

    What is proposedPreserve the descendants' protective antimicrobial memory

    With whatNot stated in the record

    HowRestrict interleukin-6 suppression to stem cells while retaining mature myeloid cell abundance, chromatin state and early antimicrobial activity

    Possible resultPossible preservation of rapid antimicrobial protection while chronic organ damage decreases
