Scientists Identify 13 Proteins Linked to Brain Aging
Blood Test Could Predict Brain Aging Milestones, Study Suggests
new research identifies 13 proteins linked to brain aging, perhaps paving the way for early interventions.
Scientists in China have made a notable breakthrough in understanding how our brains age. By analyzing blood samples from over 4,500 people in Europe, the team identified 13 proteins that appear to be reliable biomarkers for brain aging.
Published in the prestigious journal Nature Aging, the study found that the concentration of these proteins in the blood tends to peak at specific ages: 57, 70, and 78.these milestones could represent critical transition points in brain health, offering valuable insights for developing interventions to slow down or even prevent age-related cognitive decline.
“although markers related to aging have been identified before, this study pinpoints specific moments that could be crucial for potential interventions,” says Wei-Shi Liu, lead author of the study and a neurologist at a leading research institution in Shanghai.
Among the 13 proteins, Brevican (BCAN) and Growth Differentiation Factor 15 (GDF15) stood out. Both have been linked not only to aging but also to dementia, stroke, and motor function.”These findings are particularly captivating because they connect these proteins to a range of age-related neurological conditions,” explains Inés Moreno gonzález, a professor specializing in neurodegenerative diseases at the University of Málaga.While the study focused on middle-aged and older adults, Moreno González suggests that longitudinal studies starting even earlier, perhaps in people under 40, could reveal even earlier warning signs of brain aging.
“This research provides critical information about key moments throughout the aging process,” she emphasizes. ”It opens up exciting possibilities for developing targeted strategies to promote healthy brain aging.”
Blood Test Could Predict Cognitive Decline, Study Suggests
New research indicates that a simple blood test may one day be able to predict an individual’s risk of cognitive decline. The study, published in the journal Nature Aging, analyzed blood samples from over 1,000 participants and identified specific molecular changes associated with aging and cognitive function.
“This is a good study that can complement previous research on blood samples, looking at epigenetic changes in DNA related to aging,” says Jesús Ávila, a professor at the Severo Ochoa Center for Molecular Biology.
The researchers focused on “peaks” of molecular aging, previously observed in other studies, and found that these peaks were also present in the blood and correlated with cognitive performance.
“The authors verify a recent finding related to these peaks of molecular aging discovered in other studies and applicable to the cognitive domain,” explains Xavier gallart, head of the +Pec Proteomics research group at the Biomedical Research Institute of Lleida. “At the same time, it verifies that pathological aging is molecularly identifiable in blood plasma, which opens windows for intervention to improve quality of life cognitively throughout the lifespan, and to objectively measure the effects of potential interventions on specific markers,” he adds.
While promising, the study has limitations. All participants were primarily of European descent, which may limit the generalizability of the findings.
“The viability of these specific markers needs to be measured in different cohorts that clearly take into account the effects of gender, culture, and race,” Gallart concludes. “these are crucial variables that can affect both the impact and range of some of the markers defined in the study.”
Further research with more diverse populations is needed to confirm these findings and develop a reliable blood test for predicting cognitive decline.
