MUSCLE BIOPSIES OF OLDER PEOPLE

Study reveals how specific lipids indicate tissue ageing, decreases through exercise

In order to add this new chapter, the research team investigated how the composition of fats changes in mice. They looked at ten different tissues, including muscles, kidneys, liver and heart. It was noticed that one type of lipid, the bis(monoacylglycero)phosphates (or BMPs), were elevated in all tissues from the older animals. Suggesting an accumulation of these lipids during aging. They then investigated whether this also happens in humans.
