Adenosine A(2A) receptors control neuroinflammation and consequent hippocampal neuronal dysfunction.
(2011)The blockade of adenosine A2A receptors (A2AR) affords a robust neuroprotection in different noxious brain conditions. However, the mechanisms underlying this general neuroprotection are unknown. One possible mechanism ... -
Atorvastatin prevents age-related and amyloid-beta-induced microglial activation by blocking interferon-gamma release from natural killer cells in the brain
(2011)Abstract: Background: Microglial function is modulated by several factors reflecting the numerous receptors expressed on the cell surface, however endogenous factors which contribute to the age-related increase in microglial ... -
Effects of high -intensity interval vs moderate-intensity continous training on the time course adapations in cardiovascular fitness and oxygen uptake kinetics in type 2 diabetes
(Trinity College Dublin. School of Medicine. Discipline of Physiology, 2019)Individuals with type 2 diabetes mellitus (T2DM) present with significant impairments in the dynamic and peak responses of pulmonary oxygen uptake (V̇O2) during exercise. Both low-volume high-intensity interval training ... -
Immunology meets neuroscience - opportunities for immune intervention in neurodegenerative diseases
(2011)Neuroinflammatory changes are characteristic of many, if not all, neurodegenerative diseases but the extent to which the immune system is involved in the pathogenesis of these diseases is unclear. The findings of several ... -
Investigating the Effects of FTY720 on Spatial Memory and Neuroinflammation in a Rodent Model of Alzheimer's Disease
(Trinity College Dublin. School of Medicine. Discipline of Physiology, 2020)Alzheimer's disease (AD) is a progressive, age-related neurodegenerative disorder characterized by memory loss and cognitive decline, with loss of global functioning over time eventually leading to death. At the molecular ... -
Long-term potentiation is impaired in CD200-deficient mice: a role for Toll-like receptor activation.
(2011)The membrane glycoprotein CD200 is expressed on several cell types including neurons whereas expression of its receptor, CD200R, is restricted principally to cells of the myeloid lineage, including microglia. The interaction ... -
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. ... -
Priming exercise accelerates pulmonary oxygen uptake kinetics during "work-to-work" cycle exercise in middle-aged individuals with type 2 diabetes
(2021)Purpose: The time constant of phase II pulmonary oxygen uptake kinetics ([Formula: see text]) is increased when high-intensity exercise is initiated from an elevated baseline (work-to-work). A high-intensity priming exercise ... -
Pulmonary oxygen uptake and muscle deoxygenation responses during ramp incremental exercise and moderate- and heavy-intensity exercise subsequent to priming exercise in type 2 diabetes.
(Trinity College Dublin. School of Medicine. Discipline of Physiology, 2017)Middle-aged and young individuals with uncomplicated type 2 diabetes mellitus (T2DM) consistently demonstrate impairments in submaximal and maximal exercise performance, which are independent of obesity, and present in the ... -
Removal of Synaptic Ca2+-Permeable AMPA Receptors during Sleep.
(2011)here is accumulating evidence that sleep contributes to memory formation and learning, but the underlying cellular mechanisms are incompletely understood. To investigate the impact of sleep on excitatory synaptic transmission, ... -
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 ... -
Targeting the Sphingosine 1-Phosphate Axis as a Therapeutic Strategy in Krabbe's Disease: A Pre-Clinical Study.
(Trinity College Dublin. School of Medicine. Discipline of Physiology, 2020)Krabbe's disease (KD, globoid cell leukodystrophy) is a rare infantile neurodegenerative disorder, caused by the defective gene galc encoding the lysosomal hydrolase galactosylceramidase (GALC). A subsequent decreased ...
