Pressure pain thresholds increase after preconditioning 1 Hz repetitive transcranial magnetic stimulation with transcranial direct current stimulation.
(2014)BACKGROUND: The primary motor cortex (M1) is an effective target of non-invasive cortical stimulation (NICS) for pain threshold modulation. It has been suggested that the initial level of cortical excitability of M1 plays ... -
Bone marrow-derived macrophages from aged rats are more responsive to inflammatory stimuli
(2015)Background Lipopolysaccharide (LPS) and interferon-γ (IFNγ) increase expression of tumour necrosis factor-α (TNFα) that characterizes the M1 activation state of macrophages. Whereas it is accepted that the immune system ... -
Inhibition of JAK2 attenuates the increase in inflammatory markers in microglia from APP/PS1 mice
(2015)There is a wealth of evidence indicating that macrophages adopt distinct phenotypes when exposed to specific stimuli and, in the past few years, accumulating data suggest that microglia behave somewhat similarly. Therefore, ... -
Cardiovascular Control during Exercise in Type 2 Diabetes Mellitus
(2015)Controlled studies of male and female subjects with type 2 diabetes mellitus (DM) of short duration (~3–5 years) show that DM reduces peak (L·min−1 and mL·kg−1·min−1) by an average of 12–15% and induces a greater slowing ... -
Beta-amyloid-mediated inhibition of NMDA receptor-dependent long-term potentiation induction involves activation of microglia and stimulation of inducible nitric oxide synthase and superoxide
(2004)The mechanisms underlying the inhibition of long-term potentiation (LTP) induction by amyloid -peptide (A ) were investigated in the medial perforant path of the rat and mouse dentate gyrus in vitro . Evidence ... -
α-TLR2 antibody attenuates the Aβ-mediated inflammatory response in microglia through enhanced expression of SIGIRR.
(2015)The immunoregulatory function of single-Ig-interleukin-1 related receptor (SIGIRR) is derived from its ability to constrain the inflammatory consequences of interleukin (IL)-1R and toll-like receptor (TLR)4 activation. ... -
Bone Marrow-Derived Macrophages from AβPP/PS1 Mice are Sensitized to the Effects of Inflammatory Stimuli.
(2015)Macrophages are key cells in tissue defense in the periphery and, under certain circumstances, infiltrate the central nervous system, where they may play a similar role in the brain, perhaps supporting the function of ... -
Differential role of Dok1 and Dok2 in TLR2-induced inflammatory signaling in glia.
(2013)Accumulating evidence continues to underpin the role of the innate immune system in pathologies associated with neuroinflammation. Innate immunity is regulated by pattern recognition receptors that detect pathogens, and ... -
Chronic pre-treatment with memantine prevents amyloid-beta protein-mediated long-term potentiation disruption.
(2013)Previous studies indicate that memantine, a low-affinity N-methyl-D-aspartate receptor antagonist, exerted acute protective effects against amyloid-β protein-induced neurotoxicity. In the present study, the chronic effects ... -
The cannabinoid receptor type 1 is essential for mesenchymal stem cell survival and differentiation: implications for bone health.
(2013)Significant loss of bone due to trauma, underlying metabolic disease, or lack of repair due to old age surpasses the body’s endogenous bone repair mechanisms. Mesenchymal stem cells (MSCs) are adult stem cells which may ... -
Dietary quality in a sample of adults with type 2 diabetes mellitus in Ireland; a cross-sectional case control study
(2013)BACKGROUND: A number of dietary quality indices (DQIs) have been developed to assess the quality of dietary intake. Analysis of the intake of individual nutrients does not reflect the complexity of dietary behaviours ... -
Enhanced motor learning following task-concurrent dual transcranial direct current stimulation.
(2013)OBJECTIVE: Transcranial direct current stimulation (tDCS) of the primary motor cortex (M1) has beneficial effects on motor performance and motor learning in healthy subjects and is emerging as a promising tool for motor ... -
How dependent is synaptic plasticity on microglial phenotype?
(2015)Microglia are particularly plastic cells which can be shifted from their resting state by numerous factors and adopt distinct phenotypes. The cells are multifunctional, though their main role is probably maintenance of ... -
Identifying Early Inflammatory Changes in Monocyte-Derived Macrophages from a Population with IQ-Discrepant Episodic Memory
(2013)Background Cells of the innate immune system including monocytes and macrophages are the first line of defence against infections and are critical regulators of the inflammatory response. These cells express toll-like ... -
Neuroinflammatory changes negatively impact on LTP: a focus on IL-1β
(2015)In recent years it has become clear that neuroinflammatory changes develop in the brain with age and that similar, though more profound changes, occur in neurodegenerative conditions and in animal models of neurodegeneration. ... -
Pathway specific modulation of S1P1 receptor signalling in rat and human astrocytes.
(2013)BACKGROUND AND PURPOSE: The sphingosine 1-phosphate receptor subtype 1 (S1P1R) is modulated by phosphorylated FTY720 (pFTY720), which causes S1P1R internalization preventing lymphocyte migration thus limiting autoimmune ... -
Identification of Novel Genes and Pathways Regulating SREBP Transcriptional Activity.
(2009)Background Lipid metabolism in mammals is orchestrated by a family of transcription factors called sterol regulatory element-binding proteins (SREBPs) that control the expression of genes required for the uptake and ... -
SCFCdc4 acts antagonistically to the PGC-1alpha transcriptional coactivator by targeting it for ubiquitin-mediated proteolysis.
(2008)Peroxisome proliferator-activated receptor gamma (PPARgamma) coactivator-1alpha (PGC-1alpha) is a highly regulated transcriptional coactivator that coordinates energy metabolism in mammals. Misregulation of PGC-1alpha has ... -
The Schizophrenic Faces of PICK1
(2006)Schizophrenia is a grave psychiatric disorder with psychotic symptoms and an enigmatic etiology. Family studies have strongly indicated that genetic risk factors have a role in this disease. Recent findings, together ...
