Protein loss promotes age-linked brain cell activation in mice

In experiments, aged mice lacking the protein showed stronger age-linked brain cell activation, but no obvious loss of nerve insulation or faster decline in movement.In experiments, aged mice lacking the protein showed stronger age-linked brain cell activation, but no obvious loss of nerve insulation or faster decline in movement.

Experiments in adult and aged mice, against aged control miceMechanisms

Limit: The experiments did not distinguish adaptive activation from early, compensated persistent activation
