Abstract

Although fractalkine is one of chemokines involved in mediation of neuronal/microglial interaction, it is not known whether fractalkine/CX3CR1-mediated pathogenesis occurs in the rat brain following epileptogenic insults. In order to elucidate the roles of the fractalkine/CX3CR1 system in microglial activation and neurodegeneration induced by status epilepticus (SE), we investigated changes in fractalkine/CX3CR1 system within the rat hippocampus following SE. In non-SE induced animals, fractalkine and CX3CR1 immunoreactivity was detected in neurons and microglia, respectively. Following SE, fractalkine immunoreactivity was transiently increased in neurons and astrocytes. CX3CR1 immunoreactivity was also transiently detected in neurons (particularly in CA1 pyramidal cells). Intracerebroventricular infusions of recombinant rat fractalkine aggravated SE-induced neuronal damage, while fractalkine IgG or CX3CR1 IgG infusion alleviated it, compared to saline-infused animals. These findings suggest that fractalkine/CX3CR1 system may play an important role in SE-induced neuronal damages via neuron-microglial interactions.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
