Description

The abstract shows insulin promotes TDP-43 cytoplasmic redistribution with altered phosphorylation, and links this to tau isoform changes, but the mechanistic connection is unclear. This gap is critical since both TDP-43 mislocalization and tau isoform imbalances are hallmarks of neurodegeneration.
