On the development of molecular approaches to therapy for retinitis pigmentosa
(Trinity College (Dublin, Ireland). Department of Genetics, 2013)Endothelial cells lining the microvasculature of the retina have highly evolved “tight junctions” reducing the space between adjacent cells to form a selective and highly regulatable barrier called the inner blood-retina ... -
The interaction of clumping factor B and iron-regulated surface determinant protein A of Staphylococcus aureus with the squamous epithelial cell envelope protein loricrin
(Trinity College (Dublin, Ireland). Department of Microbiology, 2013)Staphylococcus aureus permanently colonises the anterior nares of 20% of the human population while the remainder is colonised intermittently. Clumping factor B (ClfB) is a surface-expressed staphylococcal protein that ... -
Identification and characterization of novel Plasmodium falciparum cyclophilins and their roles in the antimalarial actions of cyclosporin A
(Trinity College (Dublin, Ireland). Department of Microbiology, 2011)Malaria is a parasitic infection of immense global importance. The most common and severe form of the disease is caused by the blood-borne apicomplexan Plasmodium falcipanim. The lack of an effective vaccine coupled with ... -
Antimicrobial peptide preventing beer spoilage
(Trinity College (Dublin, Ireland). Department of Microbiology, 2012)Beer spoilage micro-organisms (BSMs) are a common threat to Master Brewers worldwide. Numerous studies have been carried out to date to overcome this problem, yet the most common preventative measure is the addition of ... -
Construction and development of simliki forest virus vectors for transient gene therapy of model tumours in mice
(Trinity College (Dublin, Ireland). Department of Microbiology, 2010)Cancer is a molecular and genetic disease that results from multiple alterations of genes, including proto-oncogenes and tumour-suppressor genes. Virotherapy is a branch of cancer gene therapy where oncolytic viruses are ... -
Modulation of the blood-brain barrier for therapeutic benefit
(Trinity College (Dublin, Ireland). Department of Genetics, 2014)To date this lab has carried out novel work in the area of low-molecular weight (<1 kDa) drug delivery to the retina (Campbell, Nguyen et al. 2009; Tam, Kiang et al. 2010). This work was carried by suppression of claudin-5 ... -
Transcriptional regulation by the ubiquitin system in model plant Arabidopsis thaliana
(Trinity College (Dublin, Ireland). Department of Genetics, 2014)In eukaryotes, the ubiquitin (Ub) system controls protein stability and regulates many developmental and physiological processes, in part through the regulation of transcription. Recent data show that some components of ... -
Biomass to biofuel : towards the bioengineering of Saccharomyces species for cellulose degradation
(Trinity College (Dublin, Ireland). Department of Microbiology, 2011)Cellulose is the most abundant polysaccharide on earth and therefore represents a major reservoir of sugar that could be potentially converted to alcohol and used as a fuel source. The filamentous fungus Trichoderma reesei ... -
Fibronectin-binding protein B variation in straphylococcus aureus
(Trinity College (Dublin, Ireland). Department of Microbiology, 2010)The surface-expressed fibronectin-binding proteins FnBPA and FnBPB of Staphylococcus aureus mediate attachment to immobilised fibronectin, fibrinogen and elastin. These proteins are encoded by two closely linked but ... -
Identification of factors involved in 3' end processing and transcription termination of histone mRNAs
(Trinity College (Dublin, Ireland). Department of Microbiology, 2011)The production of core histone mRNAs is tightly regulated during the cell cycle in all eukaryotic cells. Histone mRNAs accumulate during the S-phase and are subsequently degraded upon entry into G2-phase of the cell cycle. ... -
Investigation of herbicide-based compounds as novel anti-malarial agents
(Trinity College (Dublin, Ireland). Department of Microbiology, 2010)Plasmodium falciparum causes the most severe form of malaria in humans. Currently, no effective vaccine exists and the emergence of widespread drug resistance in the parasite has further increased the necessity for novel ... -
Biasing switching outcomes in the Escherichia coli fim site-specific recombination system through DNA supercoiling and nucleoid-associated proteins
(Trinity College (Dublin, Ireland). Department of Microbiology, 2010)Type 1 fimbriae are typically expressed in nutrient poor environments and facilitate colonization through attachment when the bacterium can no longer support a motile lifestyle that demands a high metabolic flux. They play ... -
Mechanical strength and inhibition of the Staphylococcus aureus collagen-binding protein Cna
(2016)The bacterial pathogen Staphylococcus aureus expresses a variety of cell surface adhesion proteins that bind to host extracellular matrix proteins. Among these, the collagen (Cn)-binding protein Cna plays important roles ... -
Molecular Interactions of Human Plasminogen with Fibronectin-binding Protein B (FnBPB), a Fibrinogen/Fibronectin-binding Protein from Staphylococcus aureus.
(2016)Staphylococcus aureus is a commensal bacterium that has the ability to cause superficial and deep-seated infections. Like several other invasive pathogens, S. aureus can capture plasminogen from the human host where it can ... -
Competing for Iron: Duplication and Amplification of the isd Locus in Staphylococcus lugdunensis HKU09-01 Provides a Competitive Advantage to Overcome Nutritional Limitation
(2016)Staphylococcus lugdunensis is a coagulase negative bacterial pathogen that is particularly associated with severe cases of infectious endocarditis. Unique amongst the coagulase-negative staphylococci, S. lugdunensis harbors ... -
Staphylococcus aureus Fibronectin-Binding Protein A Mediates Cell-Cell Adhesion through Low-Affinity Homophilic Bonds.
(2015)Staphylococcus aureus is an important opportunistic pathogen which is a leading cause of biofilm-associated infections on indwelling medical devices. The cell surface-located fibronectin-binding protein A (FnBPA) plays an ... -
Staphylokinase Control of Staphylococcus aureus Biofilm Formation and Detachment Through Host Plasminogen Activation.
(2015)Staphylococcus aureus biofilms, a leading cause of persistent infections, are highly resistant to immune defenses and antimicrobial therapies. In the present study, we investigated the contribution of fibrin and staphylokinase ... -
Engineering Saccharomyces pastorianus for the co-utilisation of xylose and cellulose from biomass.
(2015)Background Lignocellulosic biomass is a viable source of renewable energy for bioethanol production. For the efficient conversion of biomass into bioethanol, it is essential that sugars from both the cellulose and ... -
Structure-function analyses of the interactions between Rab11 and Rab14 small GTPases with their shared effector Rab coupling protein (RCP)
(2015)Rab GTPases recruit effector proteins, via their GTP-dependent switch regions, to distinct subcellular compartments. Rab11 and Rab25 are closely related small GTPases that bind to common effectors termed the Rab11 family ... -
Early farmers from across Europe directly descended from Neolithic Aegeans
(2016)One of the most enduring and widely debated questions in prehistoric archaeology concerns the origins of Europe’s earliest farmers: Were they the descendants of local hunter-gatherers, or did they migrate from southwestern ...
