A credible refinement is that any true amplification is not universal across cell types, but emerges most strongly in professional phagocytes with high endogenous LRRK2 activity, chronic cargo load, and active endolysosomal remodeling. This would reconcile modest blood-cell baseline effects with larger functional consequences in microglia/macrophages relevant to inflammatory and trafficking phenotypes.
The most supported model is that pathogenic G2019S shifts the basal catalytic set-point upward, producing higher baseline phospho-Rab output while leaving the core lysosomal volume-sensing response architecture largely intact. In this view, mutant cells begin from a higher activity floor, and the key experimental discriminator is whether baseline-normalized EC50, slope, or Emax materially increase during graded swelling.
