Scientists at UCSF and the University of New Mexico have independently identified two proteins — FTL1 (ferritin light chain 1) and OTULIN — that appear to drive brain aging and cognitive decline, with early experiments showing that blocking them can restore neuronal function in mice and cell cultures. While both discoveries represent genuine advances in understanding the molecular mechanisms of brain aging, they remain years from human application, face significant safety questions, and must contend with the field's long history of promising targets that failed in clinical trials.
