Reacción a "Study identifies proteins linked to brain ageing"

The study highlights the potential of omics sciences, in this case proteomics, and the reuse of data generated in different studies, as well as the importance of making data openly available in specialised repositories for the advancement of research in different clinical areas.

The authors verify a recent novelty related to the molecular ageing peaks discovered in other studies and applicable to the cognitive field. At the same time, it verifies that pathological ageing is molecularly identifiable in blood plasma, which provides windows for intervention to improve cognitive quality of life throughout the life cycle, and at the same time objectively measure the effects of potential interventions on specific markers.

This study generates important clinical knowledge and verifies a number of factors, but the feasibility of these specific markers must be measured in different cohorts that clearly take into account the effects of gender, culture and race, important variables that can affect both the impact and range of some markers defined in the study.
