(Submitter supplied) Multiple sclerosis (MS) is a demyelinating disease causing major neurological disability in young adults. We characterized the transcriptome of the choroid plexus (CP), which is part of the blood-brain barriers and the major site of cerebrospinal fluid (CSF) production, in the experimental autoimmune encephalomyelitis mouse model of MS. Genes encoding for adhesion molecules, chemokines and cytokines displayed the most altered expression, supporting the CP as a site of immune-brain interaction in MS. more...

(Submitter supplied) Precise control of the innate immune response is required for resistance to microbial infections and maintenance of normal tissue homeostasis. Because this response involves coordinate regulation of hundreds of genes, it provides a powerful biological system to elucidate the molecular strategies that underlie signal- and time-dependent transitions of gene expression. Using a combination of genome-wide and gene-specific approaches, we provide evidence that rather than representing off/on transitions, Toll-like receptor 4 (TLR4)-dependent activation of nearly all immediate/early (I/E) and late response genes results from a sequential process in which signal-independent factors, exemplified by Gabpa, initially establish basal levels of gene expression that are then amplified by signal-dependent transcription factors. more...

(Submitter supplied) The choroid plexus (CP) constitutes one of the blood–brain barriers – the blood cerebrospinal fluid barrier. It is formed by a monolayer of epithelial cells located within the brain ventricles and in addition to be responsible for the formation of the cerebrospinal fluid (CSF) is ideally positioned to transmit signals into and out of the brain. Specifically, here, we evaluated the overall kinetic response of the mouse CP to peripheral administration of lipopolysaccharide (LPS) that is the Gram-negative bacteria cell wall. more...

(Submitter supplied) Functional genomic analysis of frataxin deficiency reveals tissue-specific alterations and identifies the PPARγ pathway as a therapeutic target in Friedreich's ataxia Friedreich's ataxia (FRDA), the most common inherited ataxia, is characterized by focal neurodegeneration, diabetes mellitus, and life-threatening cardiomyopathy. Frataxin, which is significantly reduced in patients with this recessive disorder, is a mitochondrial iron-binding protein, but how its deficiency leads to neurodegeneration and metabolic derangements is not known. more...

(Submitter supplied) Oxidative stress is pathogenic in neurological diseases including stroke. The identity of oxidative stress-inducible transcription factors and their role(s) in propagating the death cascade are poorly understood. Microarray analysis of neurons undergoing oxidative stress showed significant induction of prodeath genes. These genes have been shown to be regulated by the bZip transcription factor, ATF4. more...
