A biochemical oscillator : experimental and theoretical studies of the peroxidase-oxidase reaction
(Trinity College (Dublin, Ireland). School of Biochemistry and Immunology, 2000)The peroxidase-oxidase (PO) reaction is the haem-peroxidase catalysed reaction of molecular oxygen with NADH, and has been shown previously to behave in an oscillatory fashion. It has been used here as a useful laboratory ... -
A comparative genomics analysis of the vertebrate immune system : genes, pathways and evolution
(Trinity College (Dublin, Ireland). School of Biochemistry and Immunology, 2009)All species possess a selection-honed collection of genes whose products function in unison to form a barricade to invading pathogens. The exponential increase in publicly available sequence data has allowed the application ... -
A role for eIF4A1 in IL-10 induction by LPS
(Trinity College (Dublin, Ireland). School of Biochemistry and Immunology, 2014)microRNAs are a family of short non-coding RNAs that act as fine tuners of gene expression by controlling mRNAs. They have been implicated in numerous diseases including inflammatory diseases. A number of studies have ... -
A role for microRNA-21 in the regulation of gastrointestinal health and disease
(Trinity College (Dublin, Ireland). School of Biochemistry and Immunology, 2017)The gastrointestinal (GI) tract is a crucial site of innate and adaptive immune regulation, balancing tolerance of beneficial commensal microorganisms and reaction to invading pathgens. Pattern recognition receptors (PRRs), ... -
A role for type 111 interferons in the natural killer cell immune response to virus
(Trinity College (Dublin, Ireland). School of Biochemistry and Immunology, 2012)Natural Killer (NK) cells are fundamental effector cells of the innate immune system that function to eliminate virally infected and transformed cells. One key way in which they do this is through the production of cytokines, ... -
A structural study of ALgE, transporter of alginate from Pseudomonas aeruginosa PAOI
(Trinity College (Dublin, Ireland). School of Biochemistry and Immunology, 2013)Pseudomonas aeruginosa is an opportunistic human pathogen that causes serious diseases in humans with immune system deficiencies, such as cystic fibrosis, wound infections, urinary tract infections, and blood stream ... -
A study of the effects of neurotoxins on the activity and copper of Ceruloplasmin
(Trinity College (Dublin, Ireland). School of Biochemistry and Immunology, 2006)This thesis focuses on the ability of neurotoxins to affect the activity of the copper transport protein ceruloplasmin (EC 1.16.3.1; ferroxidase) and its intrinsic oxidase activities. The protective properties of taurine ... -
A study of the glycosylphosphatidylinositol phospholipase C in Trypanosoma brucei
(Trinity College (Dublin, Ireland). School of Biochemistry and Immunology, 2013)Trypanosoma brucei represents a clade of flagellated parasites that cause human and animal trypanosomiases in sub-Saharan Africa. The glycosylphosphatidylinositol phospholipase C (GPI-PLC) is an endogenous enzyme that has ... -
A study of the multiple functions and interactions of semicarbazide sensitive amine oxidase
(Trinity College (Dublin, Ireland). School of Biochemistry and Immunology, 2005)This thesis focuses on three of the recognised multiple functions of mammalian semicarbazide sensitive amine oxid ase (SSAO) and the contribution of monoamine oxidase (MAO) to some of these. SSAO is a vascular-adhesion ... -
A46R and A52R from vaccinia virus are antagonists of host IL-1 and toll-like receptor signaling
(2000)Poxviruses employ many strategies to evade and neutralize the host immune response. In this study, we have identified two vaccinia virus ORFs, termed A46R and A52R, that share amino acid sequence similarity with the Toll/IL-1 ... -
Absence of Mitochondrial Uncoupling Protein 1 Affects Apoptosis in Thymocytes, Thymocyte/T-Cell profile and Peripheral T-Cell Number
(Elsevier, 2010)Our laboratory has previously demonstrated the presence of constitutively expressed mitochondrial uncoupling protein 1 in mouse thymocytes. In our endeavours to understand the role of mitochondrial uncoupling protein 1 in ... -
Absence of mitochondrial uncoupling protein 3: Effect on thymus and spleen in the fed and fasted mice
(2011)Mitochondrial uncoupling protein 3 (UCP3) is consituitively expressed in mitochondria from thymus and spleen of mice, and confocal microscopy has been used to visualize UCP3 in situ in mouse thymocytes. UCP3 is present ... -
Activation and function of mucosal gamma delta T cells
(Trinity College (Dublin, Ireland). School of Biochemistry and Immunology, 2015)γδ T cells are innate-like lymphocytes characterised by rapid activation following infection or tissue injury. They are enriched in the skin and epitheliae of various organs, where breach of the barrier is likely to occur. ... -
Activation of biliverdin-IXα reductase by inorganic phosphate and related anions
(2007)The effect of pH on the initial-rate kinetic behaviour of BVR-A (biliverdin-IX? reductase) exhibits an alkaline optimum with NADPH as cofactor, but a neutral optimum with NADH as cofactor. This has been described as dual ... -
Activation of host pattern recognition receptors by viruses
(2010)Viral recognition by the host innate immune system has become an exciting and growing area of research focus in recent years. It is now apparent that multiple pattern recognition receptor (PRR) families, including Toll-like ... -
Activation of human invariant natural killer T cells with a thioglycoside analogue of ?-galactosylceramide
(2011)Activation of CD1d-restricted invariant NKT (iNKT) cells with the glycolipid ?-galactosylceramide (?-GalCer) confers protection against disease in murine models, however, clinical trials in humans have had limited impact. ... -
Activation of innate immunity by Bordetella pertussis
(Trinity College (Dublin, Ireland). School of Biochemistry and Immunology, 2005)Respiratory infection with Bordetella pertussis is associated with the induction of Th1 cells and these cells, as well as antibody and cells of the innate immune system mediate the clearance of bacteria from the lungs. ... -
Activation of mixed glia by A-beta-specific Th1 and Th17 cells and its regulation by Th2 cells
(2010)Microglia are innate immune cells of the CNS, that act as antigen-presenting cells (APC) for antigen-specific T cells and respond to inflammatory stimuli, such as amyloid-beta (A?), resulting in the release of neurotoxic ... -
The activation of unconventional T cells by Staphylococcus aureus
