Inhibition1

  • A self-reinforcing pull between cells and tissue matrix sustains injury after clearance

    Where this hypothesis actsAfter injury and restored efferocytosis, with persistent matrix prestress and stromal traction

    What is proposedReduce traction-to-matrix coupling sufficiently to stabilize mechanical feedback

    With whatPhysical or surgical intervention

    HowUse tunable matrix anchoring and relaxation and controlled perturbations of stromal traction, leaving immune-cell history and matrix chemical composition unchanged

    Possible resultPossible decay of matrix prestress and stromal traction, with declining injury
