Aging Cell
Aging shifts the brain’s natural glow toward red in mice
Experiments in 3- and 21-month-old female mice found larger clumps of fluorescent material in brain immune cells and age-related changes in emitted light.Experiments in 3- and 21-month-old female mice found larger clumps of fluorescent material in brain immune cells and age-related changes in emitted light.
Mouse studyBiomarkers
Who was studiedYoung and aged female C57BL/6 mice, against small aggregates in young brains
What changedLarge fluorescent aggregates in aged mouse brains emitted relatively more red light than small aggregates in young brains
The catchThe red-shift comparison also differed in aggregate size, mixing size with age
