TREM2 microglial receptors can be engineered with synthetic recognition domains to selectively bind and clear cross-seeded protein aggregates while sparing monomeric forms. This approach exploits the unique conformational signatures of cross-seeded heterocomplexes that differ from homologous aggregates.
