Figure 1.New hallmarks of ageing. The figure enumerates the original hallmarks of ageing plus the five new proposed hallmarks that were discussed in the symposium. To qualify as a hallmark, the processes should change with biological age not simply in a correlative manner, but have a causal role. Hence interventions that address the hallmarks should, at the very least, halt further detrimental aspects of ageing, and preferably improve phenotypes associated with ageing.
