Article Research Highlights:

The highly specific expression of growth differentiation factor 11 (GDF11) in the central nervous system, especially in excitatory neurons, was confirmed, and the expression pattern of GDF11 was found to be significantly conserved in mouse, marmosets and human brains.

Knockout of GDF11 in excitatory neurons at the local and whole brain levels weakened the cognitive and memory functions of mice, suggesting that GDF11 plays an important role in the maintenance of neurological function.

The knockdown of GDF11 leads to the upregulation of PSMAD2 and SMAD3, which in turn promotes the increase of P21 expression, which may induce cells to enter a senescent state.

GDF11 is able to delay the aging process of excitatory neurons and the brain by inhibiting the expression of P21, improve the aging of cognitive function, and maintain the lifespan of mice. This finding provides important clues for understanding the mechanisms of brain aging and finding potential anti-aging** strategies.
