Exposure to blast overpressure (BOP) is associated with behavioral, cognitive,
and neuroimaging abnormalities. We investigated the dynamic responses of cortical
vasculature and its relation to microglia/macrophage activation in mice using
intravital two-photon microscopy following mild blast exposure. We found that
blast caused vascular dysfunction evidenced by microdomains of aberrant vascular
permeability. Microglial/macrophage activation was specifically associated with
these restricted microdomains, as evidenced by rapid microglial process
retraction, increased ameboid morphology, and escape of blood-borne Q-dot tracers
that were internalized in microglial/macrophage cell bodies and phagosome-like
compartments. Microdomains of cortical vascular disruption and
microglial/macrophage activation were also associated with aberrant tight
junction morphology that was more prominent after repetitive (3×) blast exposure.
Repetitive, but not single, BOPs also caused TNF? elevation two weeks post-blast.
In addition, following a single BOP we found that aberrantly phosphorylated tau
rapidly accumulated in perivascular domains, but cleared within four hours,
suggesting it was removed from the perivascular area, degraded, and/or
dephosphorylated. Taken together these findings argue that mild blast exposure
causes an evolving CNS insult that is initiated by discrete disturbances of
vascular function, thereby setting the stage for more protracted and more
widespread neuroinflammatory responses.
