Abstract

Increased serum levels of S100B are positively correlated with multiple forms of CNS damage, such as stroke, CNS trauma and neurodegenerative diseases, but also in psychiatric disorders. However, it is currently not known whether increased serum levels of S100B reflect a neuroregenerative or neurodegenerative response. Since glutamate receptor overactivation (excitotoxicity) may contribute to neuronal pathology in psychiatric disorders, we investigated the effect of S100B on N-methyl-d-aspartate (NMDA)-induced neuronal cell death. Here we demonstrate that very low concentrations of S100B significantly protect primary rat hippocampal neurons against NMDA toxicity by activation of transcription factors of the Rel/nuclear factor kappaB (NF-kappaB) family. Further experiments suggest that i) S100B activated expression of the receptor of advanced glycation products (RAGE) gene in neurons and ii) S100B induced a unique composition of the active NF-kappaB complex consisting of the p65 and c-Rel subunits suggesting a novel mechanism for NF-kappaB activation involved in S100B-mediated neuroprotection. Our data suggest that S100B secreted during the glial response to brain injury potently activates p65/c-Rel in a RAGE-dependent manner and may exert neuroprotective and neuroregenerative effects in psychiatric disorders.

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.
