FRET-based cAMP sensors (Epac1-camps) targeted to primary cilium (ARL13B anchor) and synaptic compartment (PSD95 anchor) provide ratiometric read-out of compartmentalized signaling. SMO agonist pharmacological challenge tests reserve capacity. Critical weakness: ciliary signaling evidence base concerns Huntington's disease and neurodevelopmental disorders—not adult-onset ALS/AD. Mechanistic link from developmental ciliary defects to progressive adult neurodegeneration is unsubstantiated.
FRAP-based measurement of TDP-43 liquid-liquid phase separation state provides a continuous biomarker of nuclear-cytoplasmic compartmentalization. Endogenous TDP-43-eGFP knock-in in iPSC neurons enables longitudinal monitoring; orthogonal validation via mAb414 nuclear pore integrity anchors imaging to ultrastructure. Primary constraint is imaging endpoint gap—two-photon FRAP is not deployable in standard trials; PET ligand development is the critical path to clinical utility.
