Comparing 2 hypotheses side-by-side
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
## Mechanistic Overview Cross-Seeding Prevention Strategy starts from the claim that modulating TARDBP within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "**Molecular Mechanism and Rationale** The cross-seeding prevention strategy targets the pathological interaction between TAR DNA-binding protein 43 (TDP-43), encoded by TARDBP, and classical neurodegenerative disease proteins such as amyloid-beta (Aβ), tau, and alpha-synucle
