Remodelling1

  • Wider cell contacts may prevent enzyme exclusion, impair clearance and renew inflammation

    Where this hypothesis actsContacts between macrophages and tissue cells or their remnants after prior damage

    What is proposedRestore intermembrane spacing that permits complete engulfment

    With whatPhysical or surgical intervention

    HowChange the length of an inert molecular linker while keeping ligand density, receptor affinity, cell composition and the current environment constant

    Possible resultPossible restoration of clearance and prevention of recurrent inflammation without changing nuclear programmes
