Scientists have discovered another factor involved in the aging process: SGDGs (3-sulfogalactosyl diacylglycerols), a type of lipid that declines in the brain with age and may have anti-inflammatory properties. The study sheds light on the molecular basis of brain aging, reveals new mechanisms underlying age-related neurological diseases, and opens up new avenues for therapeutic intervention in the future. Aging has a complicated plot and a large cast of characters, including inflammation, stress, metabolism changes, and many others. SGDGs (3-sulfogalactosyl diacylglycerols) are a class of lipids that decline in the brain with age and may have anti-inflammatory effects, according to a
