WebOct 22, 2024 · TDP-43 pathology in ALS/FTD also associates with loss-of-function variants in TBK1, a kinase involved in autophagy, as well as endosomal function ( Hao et al., 2024 ). How these mutations dovetail with TDP-43 pathology is also unclear. Both causal and risk variants have been identified for TBK1, and some studies have suggested that some of ... WebMay 5, 2024 · TDP-43 is predominantly nuclear, but it translocates to the cytoplasm under pathological conditions. Cytoplasmic accumulation, phosphorylation, ubiquitination and truncation of TDP-43 are the main hallmarks of TDP-43 proteinopathies. Among these processes, the pathways leading to TDP-43 fragmentation remain poorly understood.
