Secondary messenger signalling influences Pseudomonas aeruginosa adaptation to sinus and lung environments
(2024)Pseudomonas aeruginosa is a cause of chronic respiratory tract infections in people with cystic fibrosis (CF), non-CF bronchiectasis, and chronic obstructive pulmonary disease. Prolonged infection allows the accumulation ... -
The role of non-coding regulatory elements and PRC2 proteins in disease and development
(Trinity College Dublin. School of Genetics & Microbiology. Discipline of Genetics, 2024)Nucleosomes are the basic repeating units of chromatin. Not only do they provide a way to package the DNA into a tight nucleus, but they also contribute to the regulation of our genome. Composed of histone proteins, ... -
Understanding Tolerance to Biocides and its Consequences in Clinical Isolates of Klebsiella pneumoniae - How to Treat an ESKAPE Pathogen
(Trinity College Dublin. School of Genetics & Microbiology. Discipline of Microbiology, 2024)Biocides such as Triclosan, Benzalkonium Chloride, and Chlorhexidine have been used as disinfectants for many years, however the effects of their use and the subsequent selective pressures applied to microbial populations ... -
The transcriptional landscape and small RNAs in Acinetobacter baumannii AB5075 during antibiotic and environmental stress.
(Trinity College Dublin. School of Genetics & Microbiology. Discipline of Microbiology, 2024)Multi-drug resistant Acinetobacter baumannii is considered a major challenge because it causes a variety of serious infections. Studying these bacteria at the level of their genetic response could facilitate finding a way ... -
Understanding benzalkonium chloride tolerance and its implications in antibiotic resistance and other phenotypes in clinical isolates of Klebsiella pneumoniae
(Trinity College Dublin. School of Genetics & Microbiology. Discipline of Microbiology, 2024)In this study, clinical isolates of Klebsiella pneumoniae, a Gram-negative pathogen associated with hospital acquired infections, were tested for both phenotypic and genotypic changes following adaptation to the commonly ... -
Myeloid cell-derived proteases produce a proinflammatory form of IL-37 that signals via IL-36 receptor engagement
(2022)Interleukin-1 (IL-1) family cytokines are key barrier cytokines that are typically expressed as inactive, or partially active, precursors that require proteolysis within their amino termini for activation. IL-37 is an ... -
Ancient Genomics and Human Health
(Trinity College Dublin. School of Genetics & Microbiology. Discipline of Genetics, 2024)Studies of ancient DNA over the last decade have been pivotal in answering archaeological, evolutionary and ecological questions. More recently, this data has also been used in the analysis of human health in the past, in ... -
Investigating the roles of SMARCA4 and EP300 in synovial sarcoma
(Trinity College Dublin. School of Genetics & Microbiology. Discipline of Genetics, 2024)Synovial sarcoma is a rare and aggressive cancer that accounts for approximately 10% of all soft tissue sarcomas diagnosed annually. This malignancy is caused by a characteristic fusion protein known as SS18- SSX and is ... -
Using Micro-Synteny for Phylogenetic Inference and Analysis
(Trinity College Dublin. School of Genetics & Microbiology. Discipline of Genetics, 2024)Phylogenetics is the study of the evolutionary relationships and history of groups of organisms. Over the past twenty years, the burgeoning number of sequenced genomes has revolutionised the field of phylogenetics taking ... -
Modulation of mitochondrial function as a therapeutic strategy for Stargardt disease and an exploration of the genetic architecture of Stargardt disease in Ireland
(Trinity College Dublin. School of Genetics & Microbiology. Discipline of Genetics, 2024)Inherited retinal degenerations (IRDs) are an extremely heterogeneous group of disorders, together representing the most common cause for vision loss in young people. An estimated 5.5 million people globally are living ... -
Investigating the potential to source novel postbiotics with anti-microbial or immune-modulatory activity from distillery waste
(Trinity College Dublin. School of Genetics & Microbiology. Discipline of Microbiology, 2024)The purpose of this project is to find a novel source for antimicrobial and immunomodulatory compounds. Here we investigate the antimicrobial and immunomodulatory potential of postbiotics sourced from whisky distillation. ... -
Preventing protein-dependent biofilm formation in Staphylococcus aureus by targeting the serine aspartate repeat protein C and fibronectin binding proteins
(Trinity College (Dublin, Ireland). Department of Microbiology, 2017)Staphylococcus aureus is a leading cause of biofilm infections on indwelling medical devices. S. aureus biofilm infections are intrinsically difficult to treat. They are recalcitrant to conventional antibiotics and resistant ... -
Ecological dependencies and the illusion of cooperation in microbial communities
(2024)Ecological dependencies - where organisms rely on other organisms for survival - are a ubiquitous feature of life on earth. Multicellular hosts rely on symbionts to provide essential vitamins and amino acids. Legume plants ... -
Gene duplication in the coral genus Acropora
(Trinity College Dublin. School of Genetics & Microbiology. Discipline of Genetics, 2024)Whole Genome Duplications (WGD) pose major evolutionary events, giving rise to increased gene diversity. They have often been associated with major changes e.g. mass extinctions. The coral genus Acropora is a reef-building ... -
Targeted sequencing and in vitro splice assays shed light on ABCA4-associated retinopathies missing heritability
(2023)The ABCA4 gene is the most frequently mutated Mendelian retinopathy-associated gene. Biallelic variants lead to a variety of pheno types, however, for thousands of cases the underlying variants remain unknown. Here, we aim ... -
Detailed analysis of an enriched deep intronic ABCA4 variant in Irish Stargardt disease patients
(2023)Over 15% of probands in a large cohort of more than 1500 inherited retinal degeneration patients present with a clinical diagnosis of Stargardt disease (STGD1), a recessive form of macular dystrophy caused by biallelic ... -
Detection of pleiotropic repeat expansions and their oligogenic contribution to amyotrophic lateral sclerosis
(Trinity College Dublin. School of Genetics & Microbiology. Discipline of Genetics, 2023)This thesis aims to advance our understanding of the genetic mechanisms that contribute to amyotrophic lateral sclerosis (ALS). The focus is on investigating pleiotropy in genetic contributors to ALS by examining the ... -
Characterisation of the Genetic Mechanism Behind Floral Trichomes in Brassica rapa
(Trinity College Dublin. School of Genetics & Microbiology. Discipline of Genetics, 2023)In his seminal essay ?The Metamorphosis of Plants?, published in the 18th century, Johann Wolfgang von Goethe hypothesized that all above-ground organs of a plant, including floral organs, are derived from leaf-like ... -
Community composition drives siderophore dynamics in multispecies bacterial communities.
(2023)Background Intraspecific public goods are commonly shared within microbial populations, where the benefits of public goods are largely limited to closely related conspecifics. One example is the production of iron-scave ... -
Ecological selection of siderophore-producing microbial taxa in response to heavy metal contamination
(2018)Some microbial public goods can provide both individual and community-wide benefits, and are open to exploitation by non-producing species. One such example is the production of metaldetoxifying siderophores. Here, we ...
