Human TDP43 is required for ALS‑related annexin A11 toxicity in .

Genomics allows identification of genes and mutations associated with amyotrophic lateral sclerosis (ALS). Mutations in annexin A11 (ANXA11) are responsible for ~1% of all familial ALS and fronto-temporal dementia cases. The present study used the fruit fly, , to assess the mechanism of toxicity of ANXA11 mutants in residues that are conserved in the fly ANXB11 protein, the closest homolog to human ANXA11.

Clemastine and metformin extend the window of NMDA receptor surface expression in ageing oligodendrocyte precursor cells.

In the central nervous system, oligodendrocyte precursor cells (OPCs) proliferate and differentiate into myelinating oligodendrocytes throughout life, allowing for ongoing myelination and myelin repair. With age, differentiation efficacy decreases and myelin repair fails; therefore, recent therapeutic efforts have focused on enhancing differentiation. Many cues are thought to regulate OPC differentiation, including neuronal activity, which OPCs can sense and respond to via their voltage-gated ion channels and glutamate receptors.
