Description

General description

TAR DNA-binding protein 43 (TDP-43) plays a crucial role in regulating gene expression, RNA processing, and the transport of RNA within neurons. It is involved in maintaining neuronal health by facilitating the splicing of pre-mRNA and ensuring the stability of mRNA, which is essential for proper protein synthesis. When TDP-43 mislocalizes from the nucleus to the cytoplasm, it forms toxic aggregates that disrupt cellular function and contribute to neuronal degeneration. TDP-43 has become associated with conditions such as amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) as its abnormal accumulation often correlates with disease severity and progression. Investigation into the role of TDP-43 in neuroinflammation and neurodegeneration can help identify potential therapeutic targets that counteract its harmful effects on neuronal health and function in various neurodegenerative disorders.
