Comparing 2 hypotheses side-by-side
Synthetic RNA aptamers designed to competitively bind TDP-43's RNA recognition motifs could prevent its interaction with tau and α-synuclein mRNAs, thereby blocking the RNA-mediated cross-seeding mechanism. This approach targets the unique ability of TDP-43 to recruit other proteins through RNA scaffolding.
Loss of nuclear TDP-43 in ALS motor neurons first manifests as aberrant inclusion of the STMN2 cryptic exon 2a, producing a truncated non-functional STMN2 protein that impairs microtubule repair at the axon. This splicing defect precedes detectable cytoplasmic TDP-43 aggregation by at least 48h in iPSC motor neurons subjected to TDP-43 depletion, establishing STMN2 cryptic exon inclusion as the earliest measurable loss-of-function event. Restoring STMN2 function with antisense oligonucleotides s
