Acute systemic inflammation exacerbates neuroinflammation in Alzheimer's disease: IL-1?? drives amplified responses in primed astrocytes and neuronal network dysfunction
(2021)Neuroinflammation contributes to Alzheimer’s disease (AD) progression. Secondary inflammatory insults trigger delirium and can accelerate cognitive decline. Individual cellular contributors to this vulnerability require ... -
Anti-TLR2 antibody triggers oxidative phosphorylation in microglia and increases phagocytosis of β-amyloid
(2018)Background: Microglia are multifunctional cells that are primarily neuroprotective and a deficit in their functional integrity is likely to be a contributory factor in the deteriorating neuronal function that occurs with ... -
Biomarkers of delirium risk in older adults: a systematic review and meta-analysis
(2023)Delirium is a neuropsychiatric syndrome associated with increased morbidity and mortality in older patients. The aim of this study was to review predictive biomarkers of delirium in older patients to gain insights into ... -
Chronic neurodegeneration induces Type I interferon synthesis via STING, shaping microglial phenotype and accelerating disease progression
(2019)Type I interferons (IFN‐I) are the principal antiviral molecules of the innate immune system and can be made by most cell types, including central nervous system cells. IFN‐I has been implicated in neuroinflammation during ... -
Double stranded RNA drives anti-viral innate immune responses, sickness behavior and cognitive dysfunction dependent on dsRNA length, IFNAR1 expression and age
(2021)Double stranded RNA is generated during viral replication. The synthetic analogue poly I:C is frequently used to mimic anti-viral innate immune responses in models of psychiatric and neurodegenerative disorders ... -
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 ... -
Interactions Between Systemic Inflammation, Frailty And Neuroinflammation In Ageing And Neurodegeneration
(Trinity College Dublin. School of Biochemistry & Immunology. Discipline of Biochemistry, 2022)Compelling evidence continues to define the pivotal role which inflammation plays in the progression of neurodegenerative diseases and ageing. It has emerged that inflammation outside the brain significantly contributes ... -
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 ... -
Iron accumulation in microglia triggers a cascade of events that leads to altered metabolism and compromised function in APP/PS1 mice.
(2019)Among the changes that typify Alzheimer’s disease (AD) are neuroinflammation and microglial activation, amyloid deposition perhaps resulting from compromised microglial function and iron accumulation. Data from Genome Wide ... -
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. ... -
A population of proinflammatory T cells coexpresses αβ and γο T cell receptors in mice and humans
(2020)T cells are classically recognized as distinct subsets that express αβ or γδ TCRs. We identify a novel population of T cells that coexpress αβ and γδ TCRs in mice and humans. These hybrid αβ-γδ T cells arose in the murine ... -
The role of GPR55 in neuronal and immune cell signalling and function
(Trinity College Dublin. School of Medicine. Discipline of Physiology, 2019)The orphan G-protein coupled receptor, GPR55, is widely expressed throughout the body and is responsive to cannabinoids. However, its endogenous ligand is believed to be L-a-lysophosphatidylinositol (LPI). GPR55 is expressed ... -
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 ...
