Dr Dombrowski’s research focuses on immune mechanisms in tissue damage and repair. Tissue damage can occur in infectious (e.g. bacteria, virus, fungi) or sterile settings (e.g. trauma, autoimmune attack). The Dombrowski group is primarily interested in the underlying immunological mechanisms that direct tissue repair and regeneration with the goal to identify novel therapeutic targets for immune-mediated diseases such as Multiple Sclerosis (MS).
Despite driving pathology in many diseases, the immune system is required for tissue regeneration. Innate immune receptors sense disruption of tissue homeostasis initiating a regenerative immune response that leads to the repair of the damaged tissue. Our central goal is to elucidate the mechanisms of regenerative inflammation, in particular, the role of the innate immune system in myelin regeneration in MS.
In MS the myelin sheath that covers nerve fibres is damaged due to an autoimmune attack against proteins in the myelin sheath. As a result, the nerve fibres die leading to a loss of function, which can result in paralysis and other neurodegenerative symptoms. There is no cure for MS to date and there are no therapies that can restore damaged myelin in order to prevent nerve loss.
Current projects of the group investigate the function of inflammasomes during myelin damage and regeneration in the central nervous system (CNS) and the effects of IL-1 cytokines on oligodendrocyte progenitor cells, stem cell-like cells in the CNS that produce myelin. Other projects in the group investigate the role of inflammasomes in regenerative inflammation after infectious tissue damage and the role of e-cigarette vapour as an inflammasome activator. Dr Dombrowski has published her work in high-impact journals (e.g. Nature Neuroscience 2017) and her research has been recognized in prestigious awards including an Early Career Fellowship from The Leverhulme Trust and the invitation to the 64th Lindau Nobel Laureate Meeting for Physiology and Medicine as one of ten UK representatives.

Last week was another superb week for circadian research in the Molecular and Cellular Therapeutics Department. The Curtis Laboratory published our first big paper on the immune body clock in Nature Communications. This study originated back in 2013. I was still a postdoc in Prof. Luke O’Neills laboratory at Trinity College and was intrigued by some of the studies that showed that multiple sclerosis (MS) was affected by the circadian disruption. A key study showed that teenagers who work shift work before the age of 18 are more susceptible to multiple sclerosis in later life. I wondered if we would see any differences in multiple sclerosis if we disturbed the immune body clock. I approached Prof. Kingston Mills also at Trinity College, who is one of the world leaders of multiple sclerosis and has a key mouse model that recapitulates certain features of MS, called experimental autoimmune encephalomyelitis (EAE). The first experiment we conducted was to see if a mouse which does not have the molecular clock in macrophages was more susceptible to disease, and low and behold it was! This project was driven by one of the most talented researchers that I have ever had the pleasure of working with, Dr. Caroline Sutton, who is a senior postdoctoral fellow in Prof. Mills lab. This project is a great example of collaboration between multiple labs, Mills, O’Neill and my own new group here at RCSI.
And if that wasn’t enough! We also hosted the circadian expert Prof. Qing-jun Meng for our second institutional seminar series on Thursday. Prof. Meng is a world expert on clocks in the musculoskeletal system at University of Manchester. I met Qing-jun in 2013, and have followed his research intensely. He has made seminal discoveries on the impact of the clock on cartilage and invertebral disk function and how this leads to diseases of ageing, such as osteoarthritis and lower back pain. He had the audience enthralled for an hour with his rhythmic images of cells glowing with 24-hour rhythms, and his use of Google searches. It was an absolute pleasure to have Qing-jun with us for the day, and I hope that we can have him back again in the near future.
