Mechanistic description

Specific lipid perturbations (bis(monoacylglycero)phosphate enrichment, cardiolipin externalization) create membrane microenvironments that expose distinct amyloid-competent conformers, allowing one misfolded protein to template another’s beta-sheet formation with lipid-mediated specificity.

Mechanism / pathway

  1. PLD3
  2. neurodegeneration
