Research Interests
Ireland has one of the highest rates of childhood obesity in the world. One in four Irish school-going children are living with overweight or obesity, and as a result these children are at a higher risk of developing cardiovascular, metabolic and cancer related co-morbidities later in life. The purpose of our research is to understand how obesity drives this increased risk and aim to develop successful interventions to prevent the establishment of overt chronic disease.
The Obesity Immunology research programme aims to do this by investigating (1) how obesity impacts the immune system, driving inflammation and dysregulation, which underpins the development of the aforementioned diseases. (2) Our research also focuses on how the immune system regulates metabolism (from insulin signalling to adiposity), better understanding of these processes will allow us to identify new therapeutic strategies for obesity and its associated diseases.
To date we have published >60 peer reviewed papers in leading peer-reviewed journals including Nature Immunology, PNAS, Science Signaling, Obesity and The Journal of Immunology.

| Effect of Glucagon like peptide-1 therapy on obesity driven inflammation and co- morbid inflammatory conditions. | Scientific Lead | Obesity is a global epidemic and increases the risk of developing diseases such as type 2 diabetes mellitus (T2DM), heart disease and cancer. In lean healthy individuals the host immune system is equipped with mechanisms to deal with insults such as inflammation or malignant cells. Obese people are at greater risk of disease as their immune system is altered. Chronic inflammation plays a major role in obesity and is now seen in obese children. This results in inflamed tissues, exhausted immune cells and ultimately inflammatory disease. Glucagon like peptide-1 (GLP-1) is a gut hormone now used in the treatment of T2DM. We have reported that GLP-1 impacts inflammation and the immune system. In this study we will look in detail at how GLP-1 impacts inflammation in patients with T2DM and other inflammatory conditions including psoriasis, arthritis and asthma. We will also look in vitro at the effect of GLP-1 on cells from obese children. This will determine if GLP-1 therapy plays a role in treating the inflammation present in obesity and its co-morbid inflammatory diseases. This in turn could have major implications for practice, offering a new treatment pathway for those with T2DM and co-morbid inflammatory diseases. | 01/05/2015 | 30/04/2018 | ||
| Investigating MAIT cells in Hidradenitis Suppurativa | PI | Mucosal Associated Invariant T cells are a population of “innate” T cells, which express the invariant T cell receptor (TCR) a chain Va7.2-Ja33 and are capable of robust rapid cytokine secretion, producing a milieu of cytokines including IFN- and IL-17. MAIT cells have been reported in the gut, skin and periphery. Recent research has highlighted their involvement in numerous inflammatory diseases including rheumatoid arthritis, obesity and psoriasis. Hidradenitis Suppurativa (H.S) is a chronic inflammatory disease of the hair follicles, resulting in painful lesions of apocrine-bearing skin. Several inflammatory cytokines have been implicated in the pathogenesis of H.S including IL-17. The role of MAIT cells in H.S is currently unknown. In this study we aim to fully investigate MAIT cells in the lesions from patients with H.S. and adjacent skin. | 01/01/2020 | 31/12/2021 | 59910 | |

| Investigating the impact of childhood obesity on innate immune cell function & metabolism and their modulation by Metformin and Glucagon like peptide-1 | PI | Ireland has one of the highest rates of childhood obesity in the world. One in four Irish school-going children are either overweight or obese. These children are at a higher risk of developing cardiovascular, metabolic and cancer related co-morbidities. Furthermore, children who are obese are highly likely to be obese in adulthood. Obesity is associated with a state of chronic sterile low-level inflammation and immune dysregulation. Our group has recently reported the adverse influence of obesity and metabolic profile on innate immune cell populations, including invariant natural killer T cells (iNKT), macrophages and mucosal associated invariant T cells (MAIT) in childhood obesity. We have also described a proinflammatory adipocytokine profile in obese children. Innate cells such as iNKT cells are now highlighted as important metabolic regulators, while MAIT cells have been implicated in insulin resistance. However the mechanisms through which dysregulation occurs is largely unknown. We propose that the altered innate immune cell frequency and function in childhood obesity is due to dysregulated cell metabolism. This alteration in innate immunity ultimately increases susceptibility to metabolic disease, infection and cancer. We propose to further characterize innate immune cell populations (function and metabolism), in lean and obese cohorts of children aged between 6 and 16 years of age. We will focus on the iNKT cell, MAIT cell and Natural Killer (NK) cell. The observed immune profiling will be correlated with body weight, birth weight, systemic inflammation and metabolic syndrome status. Currently there is no protocol for targeting inflammation in childhood obesity, allowing the development of co-morbid diseases to go unchecked into adulthood. We aim to investigate the impact of the anti-diabetic agent metformin (in vivo) and the weight loss and immunomodulatory agent Glucagon Like Peptide-1 (GLP-1) (in vitro) on obesity driven inflammation in children. This will generate an expanded evidence base for potential therapeutic use in childhood obesity. | 01/08/2017 | 31/07/2020 | 275879 | |

| Investigating MAIT cell function & metabolism in Malignant Melanoma | PI | MAIT cells are a population of “innate” T cells, which can recognize bacteria-derived metabolites presented by MR1. A feature of their innateness is the ability to be activated independently of their TCR via cytokines such as IL-18. MAIT cells are involved in immunity against pathogens and are capable of robust rapid cytokine secretion, producing a milieu of cytokines including IFN-, TNF- and IL-17. MAIT cells are among the most abundant T cell subsets in humans, and have been reported in the gut, liver, skin and periphery (Godfrey et al, Nat Imm 2019). In addition to their role in host protection against bacteria, fungi and viruses, MAIT cells have also been implicated in anti-tumour responses. MAIT cells possess a full complement of cytolytic molecules, including granzyme B and perforin, and are capable of rapidly killing infected or transformed cells (Provine & Klenerman, Ann Rev Imm, 2020). MAIT cells have been investigated in numerous human cancers, with opposing beneficial and pathogenic roles reported. On one hand, MAIT cells can home to the site of the tumor in many human cancers and can produce anti-tumor molecules. On the other, MAIT cells can display defective phenotypes in certain cancer and can produce pro-tumor molecules (O’Neill et al, Cancers 2021). To date a single study has investigated MAIT cells in Malignant Melanoma (MM), highlighting them as a strong predictor of responsiveness to anti-PD-1 therapy (De Biasi et al, Nat Comm 2021). One major gap in the knowledge base is the understanding of the mechanisms underpinning cancer-related alterations in MAIT cells. Understanding how MAIT cells are regulated and how cancer modulates them will reveal novel therapeutic approaches to harness or target MAIT cells in cancer. | 01/01/2022 | 31/12/2022 | 75627 | |

| NK cell RESTORE | PI | Natural Killer (NK) cells are a population of lymphocytes which classically form part of the innate immune system, due to their ability to kill transformed cells without prior activation. NK cells are also rapid producers of lytic molecules and inflammatory cytokines such as IFN-, and are therefore a critical component of early immune responses in cancer. Obesity is a worldwide epidemic, with over 600 million adults and 124 million children now classified as obese. It is well established that individuals who are obese are at a higher risk of many acute and chronic conditions, including many cancers. Over the past 10 years many studies including ours have detailed obesity induced systemic dysregulation of NK cell functions. This ultimately increases the risk of cancer in the most severely obese patients, and decreases their prognosis. GLP-1 analogue therapy is the current gold-standard in weight loss pharmacology. We have previously reported that GLP-1 therapy can also modulate the immune system in obese patients, independent of weight loss. We have preliminary data which suggests that GLP-1 analogue therapy can restore NK cell numbers and functions in severely obese patients. The mechanisms through how this happen are unknown. In this project we propose to investigate if GLP-1 can restore NK cell number and function in a cohort of obese patients, we will elucidate the mechanisms driving restoration, and determine if the benefits independent of weight loss. Collectively these studies will identify novel benefits for GLP-1 therapy in a cohort of at-risk obese patients. Furthermore, it may identify novel pathways regulating NK cell functions which could extend beyond obesity. UCD Lead- unclear budget coming to MU. | 01/11/2019 | 31/10/2022 | 70200 | |
