In the evolutionary history of life, the ability of a cell to separate its inner world from the external environment was an important turning point. The so-called plasma membrane lets cells control ...

Far from a static barrier, the brain’s extensive interface with the blood is increasingly being appreciated as an active border, one that serves not only to keep some proteins out, but to let others ...

(89Stocker/Canva) Science is one step closer to cracking the code of longevity thanks to a new study that identified dozens of proteins linked with slower aging in the blood of centenarians.

Swiss researchers studying the blood of people who lived past 100 have pinpointed 37 proteins that appear to distinguish centenarians from both younger healthy adults and older hospitalized patients, ...

Blood-based plasma proteomics offers insights into systemic biology, but sample degradation can obscure critical signals. Preanalytical issues, such as delayed plasma processing, platelet activation, ...

Alzheimer's disease affects an estimated 7.2 million Americans age 65 and older, according to the Alzheimer's Association. Current tests often measure the levels of two proteins-amyloid beta (Aβ) and ...

Researchers developed a blood test that analyzes structural changes in three proteins linked to Alzheimer’s progression. Protein folding patterns distinguished healthy individuals, mild cognitive ...
