Increased CD3 Immunoreactive Cells Persist Chronically in the Brain Parenchyma in Association with Focal Cortical Contusion following Experimental TBI

Kristen D Esannason Munroe, Alexandra V. Ulyanova, Rebecca Donahue…·John A. Wolf

This study shows that T-cell infiltration persists chronically in the brain after focal cortical contusion in swine, but not with inertial injury, suggesting an adaptive immune response to TBI.
