Researchers at Stanford University have established that humans age in many stages. Their conclusions are based on the study of changes in plasma proteins.
A team of researchers from Stanford University analyzed 2,925 plasma proteins of 4,263 people aged 18 to 95, reports Nature Medicine.
Thanks to a new bioinformatics approach, they revealed non-linear alterations of the human plasma proteome with age.
Three decades subject to major alterations
The researchers concluded that major alterations occur during the fourth, seventh and eighth decades of life, more specifically at 34, 60 and 78 years of age.
According to the review, this new approach to the study of aging has identified signatures and unexpected pathways that could target the potential reasons for age-related diseases.
