**4.8 Gene therapy**

Genes are promising research targets to delay the aging process and extend longevity (**Figure 15**) [24]. Gene therapy allows the modulation of the genome architecture using both direct (by gene editing) and indirect (by viral or non-viral vectors) approaches. However, these genetic interventions may be difficult to implement in humans without knowing all the potential health consequences during an entire life.
