11. These findings identify a vicious feedback cycle for dipeptide-repeat protein-mediated TDP-43 and subsequent KPNA pathology, which becomes self-sufficient of the initiating trigger and causes C9orf72-related neurodegeneration.

12. The TARDBP p.N267S heterozygous mutation was detected in one sporadic Parkinson's disease patient. The p.N267S mutation was not found in a control population of 450 healthy individuals and in our 165 familial Parkinson's disease.

13. Examined two specific C-terminal fragments of TDP43 (TDP43(219) and TDP43(247)), which are approximately 85% identical and differ at their N termini by 28 amino acids. We found that TDP43(247) is degraded primarily by the Arg/N-end rule pathway, whereas degradation of TDP43(219) continues in the absence of ATE1.

14. This study proposed that the presence of full-length TDP-43s in the matrix is a primary cause of mitochondrial damage.

15. protein interactors with TDP-43 did demonstrate differences between control and Amyotrophic Lateral Sclerosis Spinal-Cord Lysates, with the sALS and mtSOD1 harboring cases examined differing from the protein interactors identified in the FUS 3' UTR mutation and c9orf72 repeat-positive cases.

16. This study demonstrates that aggregates of phosphorylated TDP-43 may be identified in the skeletal muscle of both sALS and fALS patients

17. SGs form distinct cytoplasmic structures that can indirectly enhance TDP-43 aggregation

18. TDP-43 is an essential protein for normal skeletal muscle formation that unexpectedly forms cytoplasmic, amyloid-like oligomeric assemblies, which we call myo-granules, during regeneration of skeletal muscle in mice and humans; myo-granules bind to mRNAs that encode sarcomeric proteins and are cleared as myofibres mature

19. Ubiquitinylation at Lys-84 promotes nuclear import, while ubiquitinylation at Lys-95 or Lys-408 impairs phosphorylation of TDP-43 at Ser(409,410).

20. Using single-molecule fluorescence and ensemble biophysical techniques, and a wide range of pH and temperature conditions, this study shows that TDP-43(N-Terminal Domain ) is thermodynamically stable, well-folded and undergoes reversible oligomerization.

3. This study identifies TDP-43 misregulation as a pathogenic mechanism that may underpin ALS-FTD and exploits phenotypic heterogeneity to yield candidate suppressors of neurodegenerative disease

4. Study shows that TDP-43 interacts with mitochondrial proteins critical for mitophagy and mitochondrial dynamics. This suggest that TDP-43 processing may contribute to metabolism and mitochondrial function.

5. These results indicate that the local complement activation and increased expression of C5aR1 may contribute to motor neuron death and neuromuscular junction denervation in the TDP-43(Q331K) mouse ALS model.

6. This study demonstrated here that muscle-dominant TDP-43 transgenic mice had lower body weights and increased serum levels of myogenic enzymes

7. Our findings provide a novel pathogenic mechanism and highlight how TDP-43 gain of function and loss of function affect RNA processing differently, suggesting they may act at different disease stages.

8. Demonstrate that TDP-43 is indispensable for oligodendrocyte survival and myelination, and loss of TDP-43 in oligodendrocytes exerts no apparent toxicity on motor neurons.

9. morphologic alterations that were associated with the TDP-43(Q331K) mutation, such as aberrant innervation patterns and the distribution of synaptic vesicle-related proteins, which is indicative of a failing neuromuscular junction (NMJ) undergoing synaptic remodeling. These findings support a growing acceptance that dysregulation of the NMJ function is a key early event in the pathology of amyotrophic lateral sclerosis.

10. Findings highlight that the phosphatase regulator, GADD34, also functions as a kinase scaffold in response to chronic oxidative stress and recruits CK1 and oxidized TDP-43 to facilitate its phosphorylation, as seen in TDP-43 proteinopathies.

11. FUS and TAF15 exhibit similar global RNA interaction profiles in vivo, but affect a strikingly small subset of common genes. Unexpectedly, TAF15 influences a small fraction of amyotrophic lateral sclerosis events compared with TDP-43 and FUS in the mouse CNS.

12. Increased excitatory synaptic inputs and dendritic spine densities is associated with TDP-43(Q331K) mutation resulting in amyotrophic lateral sclerosis.

13. Given the close association of stress granules and TDP-43, we wondered whether internalisation of SOD1 aggregates stimulated TDP-43 cytosolic aggregate structures. Addition of recombinant mutant G93A SOD1 aggregates to NSC-34 cells was found to trigger a rapid shift of TDP-43 to the cytoplasm where it was still accumulated after 48 h.

14. The mutated TDP-43 has a significant pathological effect at the dendritic spine that is associated with attenuated neural transmission.

19. this study shows that HSF1 overexpression protects against TDP-43 pathology by upregulation of chaperones, especially HSP70, rather than enhancing autophagy

20. Acetylation of the protein triggers TDP-43 pathology in cultured cells and mouse skeletal muscle, which can be cleared through an HSF1-dependent chaperone mechanism that disaggregates the protein.
