Abstract

The transcription factor Rel/nuclear factor (NF)-κB is known for its fundamental role in regulating immune and inflammatory responses. In the brain, constitutive NF-κB activity has been detected exclusively in neurons, and a large diversity of stimuli have been reported to induce NF-κB activity. Yet the function of this transcription factor in the nervous system remains unclear, and its role in neuroprotection or neurodegeneration is open to debate. Recently it was suggested that κB-driven gene expression in neurons is controlled by Sp1-like factors. To clarify such controversy, we have characterized here a novel mouse model in which the entire NF-κB-dependent transcriptional response is abolished in the forebrain. Calcium-calmodulin-dependent kinase II α promoter-driven tetracycline transactivator was used for regulated expression of a transdominant negative mutant of inhibitor κBα (super-repressor) together with a green fluorescent protein tracer. Inhibition of expression of a κB-dependent lacZ transgene was shown in triple transgenic mice, which correlated with the loss of κB-specific DNA binding. In transgenic organotypic hippocampal slice cultures, expression of the super-repressor led to strong cell death after neurotoxic insults. These data demonstrate for the first time that neuron-restricted ablation of NF-κB-driven gene expression increases neurodegeneration. This might lead to the path for new treatments of neurodegenerative diseases.

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.
