Hi Usha, I would be happy to discuss the misinformed narrative about the Alzheimer’s field Piller is pushing. And perhaps you or he can explain why my ongoing work and that of thousands of others is part of a “Devastating Legacy of Lies.”

I fully agree. The term LLPS is probably not the correct one to describe what happens in cells. However, the formation of dynamic low-order condensates driven by low affinity multivalent proteins (often highly disordered) seems to occur in cells.

If not LLPS, what term would you use to describe these quick off-rate polyvalent structures that show rapid FRAP recovery, droplet-mixing, etc? QuORPS?

Well I see the appeal of using “liquid” as a term to describe a collection of polyvalent interactors, sliding along one another through rapid associations and dissociations. What would be a better term for this, distinct from aggregates with irreversible monovalent (oligovalent?) interactions?

Do you think it better to describe condensates as concentrations of disordered macromolecules with specific but polyvalent interactions and quick off-rates?

Thanks guys. To be clear, I still favor that antibody directly binding to CAA could be a cause of ARIA. We just found that the difference in ARIA-E between lec and adu can’t be fully explained by differences in CAA preference.
