WebApr 6, 2024 · TDP-43, a protein that is known to have toxic effects in amyotrophic lateral sclerosis (ALS), is able to interact with RNA molecules carrying a chemical modification called m6A, and this chemical modification is increased in ALS nerve cells, a new study shows. The findings add to a growing body of evidence suggesting that abnormal RNA ... 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 ...
