Blood Plasma Protein Fibrinogen Interacts Directly with Nerve Cells to Cause Brain Inflammation

Interactions of blood plasma protein fibrinogen with its receptors, cellular prion protein (above) and intercellular adhesion molecule (below), on the surface of neurons are shown with red dots using a method called proximity ligation assay.  The presence of red dots indicates interaction of the target protein with its receptor. Neuronal nuclei are shown in blue.  — Microscopic images courtesy of Lominadze Laboratory, USF Health

Neuroinflammatory diseases, including Alzheimer’s disease and traumatic brain injury, have been linked to deposits of a tough protein known as fibrin, derived from the blood clotting factor fibrinogen. These mesh-like fibrin deposits occur outside blood vessels in the brain, contributing to the death of neurons that eventually leads to impaired memory.
