AD/PD 2026: Brain Barrier Function Shapes NfL Levels in Blood

At the AD/PD 2026 Conference, Helena Sophia Gleerup presented a study that examines the relationship between the permeability of the blood–CSF barrier (BCB) and serum concentrations of NfL. The results emphasise the importance of considering the brain’s barrier function alongside neuronal damage in neurodegenerative diseases.
