Trovò and colleagues find that aging is accompanied by a decrease in the levels of the phosphoinositide PI(4,5)P2, PLCγ activity and the PI(4,5)P2-clustering molecule MARCKS in mouse hippocampal synaptic membranes. Moreover, increasing MARCKS levels in old mice corrects some of the synaptic plasticity and memory deficits associated with aging.
