The effect of the pneumococcal toxin, pneumolysin on brain ependymal cilia.

Abstract excerpt

Densely ciliated ependymal cells cover the ventricular surface of the brain and cerebral aqueducts separating cerebrospinal fluid, which is infected in meningitis, from neuronal tissue. We have established an ex vivo model that allows measurement of ependymal ciliary beat frequency, using high-speed video analysis, during incubation with bacterial toxins. Ciliated ependyma, from Wistar rats, was exposed to the...
