Dhaka, Oct. 17 -- Scientists have identified an enzyme that breaks down fatty compounds as a possible shield for ageing memory and brain cells, drawing on mice, human brain samples and laboratory cells, Nature reports.

The study, published in Nature Neuroscience on Oct 15, identified the phospholipase enzyme, encoded by the PLA2G2F gene, as a potential contributor to cognitive resilience -- the ability to maintain memory and thinking skills despite age-related brain changes.

Researchers found that older mice lacking the gene developed greater brain inflammation and more severe neuron deterioration than unaltered mice.

Animals with increased gene activity, meanwhile, showed less inflammation and better-connected neurons, according to th...
