The coronavirus disease 2019 (COVID-19) pandemic has been linked to long-term neurological effects with multifaceted complications of neurodegenerative diseases. Several studies have found that pathological changes in transactive response DNA-binding protein 43 kDa (TDP-43) are involved these cases. This review explores the causal interactions between severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and TDP-43 from multiple perspectives. Some viral proteins SARS-CoV-2 shown induce through its cleavage, aggregation, mislocalization. infection can cause liquid−liquid phase separation stress granule formation, which accelerate condensation TDP-43, resulting host RNA metabolism disruption. proposed interact RNA, though role replication remains be fully elucidated. interaction potentially facilitates replication, while viral-induced oxidative protease activity pathology. Evidence both clinical experimental indicates may contribute sequelae, including amyotrophic lateral sclerosis-like frontotemporal dementia-like features, as well increased phosphorylated deposition central nervous system. Biomarker further support link dysregulation COVID-19 (long COVID). In this review, we presented a novel integrative framework pathology, bridging gap mechanisms neurodegeneration. These findings underscore need for research clarify TDP-43-related neurodegeneration underlying develop therapeutic strategies aimed at mitigating patients long COVID.
