3. Study confirms the high expression of hTDP-43 in the CNS, increased microgliosis and motor deficits, exhibiting further prominent ALS/FTLD pathologies, such as cytoplasmic and insoluble TDP-43 in TAR6/6 mice. This model represents not only pathological TDP-43 expression but also disease-relevant posttranslational changes. PMID: 29787578
4. The relevance of contact-independent cell-to-cell transfer of TDP-43 and SOD1 in amyotrophic lateral sclerosis. PMID: 28711596

11. Study demonstrated TDP-43/pTDP-43 deposition in skin nerves in ALS patients. Although the mechanisms underlying TDP-43 in ALS are currently unknown, its detection is of interest, and the deposition may occur not only in ALS but also during the aging process which is based on observations of the present study. PMID: 29804146
12. Both ALS and FTD patients presented with higher TDP-43 and tauT levels compared to the control group.

23. SOD1 mutations were present in 20% of familial amyotrophic lateral sclerosis (ALS) patients and 1.9% of sporadic ALS patients, while FUS mutations were responsible for 13.3% of familial ALS cases, and TARDBP mutations were rare in either familial or sporadic ALS cases. PMID: 27604643
24. an alpha-helical component in the centre (residues 320-340) of the C-terminal domain is related to the protein's self-association and LLPS. Systematically analysing ALS-related TDP-43 mutants (G298S, M337V, and Q331K) in different buffer conditions at different temperatures, we prove that this phase separation is driven by hydrophobic interactions but is inhibited by electrostatic repulsion.

26. both FUS and TDP43 colocalize with active RNA polymerase II at sites of DNA damage along with the DNA damage repair protein, BRCA1, and FUS and TDP43 participate in the prevention or repair of R loop-associated DNA damage, a manifestation of aberrant transcription and/or RNA processing PMID: 27849576
27. The data of this study suggest that TDP-43 pathology is associated with age and exacerbated by the presence of concomitant Alzheimer's disease pathology. PMID: 27495267
28. The A382T mutation in TARDBP caused a reduction in the ability of cells to respond to stress through loss of TDP-43 function in stress granule nucleation.

31. ALS-mutant linked TDP-43 mutations expressed at moderate levels in a pattern mimicking endogenous TDP-43 also cause toxicity in a non-cell autonomous manner. Eliminating mutant TDP-43Q331K synthesis in a proportion of motor neurons delayed disease onset, reduced aberrant nuclear morphology in those neurons at early disease stages, and almost eliminated age-dependent accelerated death of those motor neurons. PMID: 28357566
32. Study reports that cryptic exon incorporation occurred not only in Alzheimer' disease brains exhibiting TDP-43 pathology, but also in neurons lacking cytoplasmic inclusion but exhibiting nuclear clearance of TDP-43. PMID: 28332094
33. 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. PMID: 28724966

38. Authors observed impaired levels of glutathione (downstream Nrf2 antioxidant) in TDP-43M337V patient fibroblasts and astrocyte cultures from TDP-43Q331K mice, indicative of elevated oxidative stress and failure of some upregulated antioxidant genes to be translated into protein. PMID: 28334913

47. The present study, based on 15 cases staged for pTDP-43 pathology, reports the finding that pathologically altered TDP-43 in Betz cells reacts differently than that in bulbar or spinal alpha-motoneurons. The major differences between the two types of histological profiles are discussed within the context of their possible consequences and implications for the potential further progression or spread of the pTDP-43 lesions.
