Blockade5

  • Neutrophil movement may shift damage between organs and mimic lasting recovery

    Where this hypothesis actsDuring blockade of neutrophil engulfment, with prolonged assessment of muscle, lung and heart function

    What is proposedSuppress EP2 activity

    With whatNot stated in the record

    HowNot stated in the record

    Possible resultPossible local functional improvement with redistribution of neutrophils and delayed damage in other organs

  • Shared lipid synthesis in neutrophils and platelets may limit tissue damage

    Where this hypothesis actsResident macrophage environment and coordinated lipid synthesis by neutrophils and platelets

    What is proposedSuppress EP2 activity

    With whatNot stated in the record

    HowNot stated in the record

    Possible resultPossible reduction in SPV_3 and new damage across several tissues despite blocked neutrophil engulfment

  • Suppressing a prostaglandin receptor may curb ferroptosis through itaconate

    Where this hypothesis actsResident macrophages while neutrophil engulfment remains blocked

    What is proposedSuppress EP2 to promote itaconate-mediated protection of neighboring cells

    With whatNot stated in the record

    HowNot stated in the record

    Possible resultPossible functional improvement across organs despite persistent neutrophils and their damaging products

  • Vesicle removal may limit damage from elastase shielded against its natural inhibitor

    Where this hypothesis actsDuring blockade of whole-neutrophil engulfment

    What is proposedSuppress EP2 activity

    With whatNot stated in the record

    HowNot stated in the record

    Possible resultPossible restoration of vesicle uptake by macrophages and retention of multisystem benefits

  • Delaying neutrophil uptake may preserve vesicle-mediated complement inhibition

    Where this hypothesis actsDuring recovery from injury, alongside selective inhibition of neutrophil engulfment

    What is proposedSuppress EP2 receptor activity

    With whatNot stated in the record

    HowNot stated in the record

    Possible resultPossible multisystem recovery benefits enhanced by delaying neutrophil engulfment
