Myelomonocytic cell recruitment causes fatal CNS vascular injury during acute viral meningitis


Lymphocytic choriomeningitis virus1 infection of the mouse central nervous system (CNS) elicits fatal immunopathology through blood–brain barrier breakdown2 and convulsive seizures3. Although lymphocytic-choriomeningitis-virus-specific cytotoxic T lymphocytes (CTLs) are essential for disease4, their mechanism of action is not known. To gain insights into disease pathogenesis, we observed the dynamics of immune cells in the meninges by two-photon microscopy. Here we report visualization of motile CTLs and massive secondary recruitment of pathogenic monocytes and neutrophils that were required for vascular leakage and acute lethality. CTLs expressed multiple chemoattractants capable of recruiting myelomonocytic cells. We conclude that a CD8+ T-cell-dependent disorder can proceed in the absence of direct T-cell effector mechanisms and rely instead on CTL-recruited myelomonocytic cells.
