Acute Inflammation Alters Brain Energy Metabolism in Mice and Humans: Role in Suppressed Spontaneous Activity, Impaired Cognition, and Delirium
(2020)Systemic infection triggers a spectrum of metabolic and behavioral changes, collectively termed sickness behavior, which while adaptive, can affect mood and cognition. In vulnerable individuals, acute illness can also ... -
Acute transient cognitive dysfunction and acute brain injury induced by systemic inflammation occur by dissociable IL-1-dependent mechanisms
(2018)Systemic inflammation can impair cognition with relevance to dementia, delirium and post-operative cognitive dysfunction. Episodes of delirium also contribute to rates of long-term cognitive decline, implying that these ... -
The Adam family metalloprotease Kuzbanian regulates the cleavage of the roundabout receptor to control axon repulsion at the midline.
(2010)Slits and their Roundabout (Robo) receptors mediate repulsive axon guidance at the Drosophila ventral midline and in the vertebrate spinal cord. Slit is cleaved to produce fragments with distinct signaling properties. In ... -
Altered Expression of Caspases-4 and -5 during Inflammatory Bowel Disease and Colorectal Cancer - Novel Diagnostic and Therapeutic Potential.
(2015)Caspases are a group of proteolytic enzymes involved in the co-ordination of cellular processes, including cellular homeostasis, inflammation and apoptosis. Altered activity of caspases, particularly caspase-1, has ... -
Amyotrophic lateral sclerosis mutant vesicle-associated membrane protein-associated protein-B transgenic mice develop TAR-DNA-binding protein-43 pathology.
(2010)Cytoplasmic ubiquitin-positive inclusions containing TAR-DNA-binding protein-43 (TDP-43) within motor neurons are the hallmark pathology of sporadic amyotrophic lateral sclerosis (ALS). TDP-43 is a nuclear protein and the ... -
An analysis platform and tools to understand the dynamics of neuronal encoding in rodents
(Trinity College Dublin. School of Psychology. Discipline of Psychology, 2019)The principal goal of the proposed project is to develop a data analysis framework that incorporates analytical methods for the study of cognitive map represented by neurons in vivo recorded from chronically implanted ... -
The anterior thalamus provides a subcortical circuit supporting memory and spatial navigation.
(2013)The anterior thalamic nuclei (ATN), a central component of Papez' circuit, are generally assumed to be key constituents of the neural circuits responsible for certain categories of learning and memory. Supporting evidence ... -
At the extreme end of the psychoneuroimmunological spectrum: delirium as a maladaptive sickness behaviour response
(2013)Delirium is a common and severe neuropsychiatric syndrome characterised by acute deterioration and fluctuations in mental status. It is precipitated mainly by acute illness, trauma, surgery, or drugs. Delirium affects ... -
Atypical disease after Bordetella pertussis respiratory infection of mice with targeted disruptions in Interferon- Receptor or Immunoglobulin ? Chain Genes
(The Rockefeller University Press, 1997)Using a murine respiratory challenge model we have previously demonstrated a role for Th1 cells in natural immunity against Bordetella pertussis, but could not rule out a role for antibody. Here we have demonstrated that ... -
Biophysical stimuli induced by passive movements compensate for lack of skeletal muscle during embryonic skeletogenesis
(University of Edinburgh (datashare), 2011)In genetically modified mice with abnormal skeletal muscle development, bones and joints are differentially affected by the lack of skeletal muscle.We hypothesise that unequal levels of biophysical stimuli in the ... -
Bipolar affective puerperal psychosis- genome-wide significant evidence for linkage to chromosome 16.
(American Psychiatric Publishing, 2007)OBJECTIVE: Vulnerability to the triggering of bipolar episodes by childbirth aggregates in families and may define a genetically relevant subtype of bipolar disorder. The authors conducted a search by systematic whole ... -
The c-Abl tyrosine kinase phosphorylates the Fe65 adaptor protein to stimulate Fe65/amyloid precursor protein nuclear signaling.
(American Society for Biochemistry and Molecular Biology, 2004)The amyloid precursor protein (APP) is proteolytically processed to release a C-terminal domain that signals to the nucleus to regulate transcription of responsive genes. The APP C terminus binds to a number of phosphotyrosine ... -
CARDINAL, a novel caspase recruitment domain protein, is an inhibitor of multiple NF-kappa B activation pathways.
(2001)Proteins possessing the caspase recruitment domain (CARD) motif have been implicated in pathways leading to activation of caspases or NF-kappaB in the context of apoptosis or inflammation, respectively. Here we report the ... -
Caspase-1 promiscuity is counterbalanced by rapid inactivation of the processed enzyme.
(2011)Members of the caspase family of cysteine proteases coordinate the highly disparate processes of apoptosis and inflammation. However, while hundreds of substrates for the apoptosis effector caspases (caspase-3 and caspase-7) ... -
CD4+ T-lymphocyte telomere length is related to fibrosis stage, clinical outcome and treatment response in chronic hepatitis C virus infection.
(Elsevier, 2010)BACKGROUND & AIMS: Increasing age is associated with impaired immune function and in chronic HCV infection specifically, with progressive fibrosis, liver failure, HCC and impaired responses to antiviral therapy. T-lymphocyte ... -
Characterization of two protein disulphide iosmerases from the endocytic pathway of Trypanosoma brucei
(American Society for Biochemistry and Molecular Biology, 2005)Proteins from the endocytic pathway in bloodstream forms of Trypanosome brucei are modified by the addition of linear poly-N-acetyllactosamine side chains, which permits their isolation by tomato lectin affinity chromatography. ... -
Citrate, oxaloacetate and 2-hydroxyglutarate in the control of inflammatory macrophage activation
(Trinity College Dublin. School of Biochemistry & Immunology. Discipline of Biochemistry, 2020)Immunometabolism is the study of changes that occur in the metabolic pathways of an immune cell during its activation. For macrophages, the remodelling of their metabolism following activation supports the adoption of ...
