Pathological blood vessel formation (angiogenesis), or the inability of endothelial cells to perform their physiological function (endothelial dysfunction), are defining features of disease. The endothelium actively controls vessel integrity, vascular growth and remodelling, tissue growth and metabolism, immune responses, cell adhesion, angiogenesis, haemostasis and vascular permeability. It is, therefore, a vital and largely unexploited target for novel therapies.
Prof Tracy Robson’s team have identified and characterised a novel anti-angiogenic protein, FK506 binding protein like – FKBPL, significantly advancing our understanding of the anti-angiogenic process, in particular, how tumours recruit blood vessels to support their growth. This led to a collaborative study with Almac Discovery to develop therapeutic peptides based on FKBPL’s active domain to explore their potential in cancer by targeting the ability of tumours to recruit blood vessels to grow, invade and metastasise beyond the site of the primary tumour. The team are also testing the ability of these peptides to sensitise tumours to current therapies and to target cancer stem cells that lead to the onset of resistance and/or recurrent disease. Importantly, these studies led to a ‘first in man’ phase I clinical in cancer patients where the clinical candidate drug, ALM201, was very well tolerated over a wide range of doses. Prof Robson’s team (Dr Stephanie Annett and Dr Gillian Moore) will discuss this data together with new data suggesting a strong role for FKBPL in vascular endothelial dysfunction and possible implications therefore in other diseases associated with vascular disease.

Sepsis is a major challenge in the intensive care unit, where it is one of the leading causes of death. It arises unpredictability and can progress rapidly. Globally there are an estimated 30 million cases of sepsis each year which results in more than 8 million deaths in adults and 5 million deaths in children. Of those who do survive a further one third will die in the following 12 months, those who survive often face life-long consequences, such as new physical, mental and cognitive problems. Although this number is gathered from several sources, all content to the fact that it is likely an underestimate and therefore may very well be the leading cause of mortality worldwide. Currently, there are no approved drugs on the market to control the underlying pathophysiology that triggers the dysregulated host response to sepsis and therefore the management plan focuses on reducing the infection through the use of aggressive intravenous antibiotic therapy and source control. Therefore the cardiovascular infection research group is investigating a therapeutic option that acts early to prevent bacteria binding to the host vascular endothelial cell in the first place would be commercially advantageous as it will prevent the infection from progressing to septic shock and a life-threatening situation as a result of multi-organ failure.

Did you ever wonder what was the significance of the white coat ceremony and what impact it can have on students and faculty who attend?
Dr. Orna Tighe, Dr. Judith Strawbridge, Dr. Alice McGarvey and Prof Hannah McGee explain the evolution of this ceremony at RCSI on the blog of Journal of Interprofessional Care. They touch on the history of the white coat ceremony, it’s associated symbolism, how this ceremony became a tradition in RCSI and has now developed into a unique interprofessional White Coat ceremony, offering an opportunity for multidisciplinary healthcare professionals to develop interprofessional socialization at an early point in their education. The philosophy and the value of this ceremony in RCSI are discussed.
Have a look at some messages from the story and read the original here.
“We recognized that the ceremony needed to be more than just bringing students together and consequently it was developed to ensure that student voice was central, while emphasizing institutional support for interprofessional collaboration”…
“In summary, our experience suggests that the initial power of the white coat metaphor has evolved within RCSI to deliver what is a novel inspirational Interprofessional Ceremony in the very first week of the students’ programs”
On Friday, March 23rd, MCT and the Department of Physiology hosted a Spinathon for Daffodil Day, the Irish Cancer Society’s biggest fundraising day of the year. The aim of the Spinathon was to cycle the same distance as the Ring of Kerry, a total of 170 km on each bike. A number of willing participants took part on the day, including Sudipto, Lisa, George and Tony from MCT. A total of €1966 between the JustGiving.ie fundraising page and bucket collections on the day.
The day began with myself (in the middle of the pic) and Brian O’Mahony (the CEO of the IHS) appearing on Ireland AM to speak about the development of Haemophilia care in Ireland over the last 50 years.
The celebrations continued with the revealing of a street art project reflecting the personal experience of patients and nurses from St James’s Hospital. The visual, commissioned by the Irish Haemophilia Society in partnership with Roche, was developed by artist Shane O’Malley and unveiled on Machen street and in St. James’s Hospital to coincide with World Haemophilia Week.
Brian O’Mahony and Dr. Michelle Lavin spoke at the Shire office about personalised treatment as well as the challenges that still need to be addressed to further our understanding of Haemophilia.
The Day concluded with the “light it up red” light show, a long list of landmarks including RCSI, Edinburgh castle and the convention Centre were among landmarks worldwide which were lit up red for the night.
Neuroblastoma is a cancer of the nervous system that primarily affects children aged 5 and younger. Although neuroblastoma accounts for only 5% of childhood cancers, it is responsible for approximately 15% of childhood cancer deaths. For children with high-risk neuroblastoma – children in which cancer has spread significantly – the outlook is extremely poor. Approximately 1 in 5 of these children will not respond to treatment, and of those that do, 50% will develop drug resistance leading, in many cases, to death.
Dr Olga Piskareva, an NCRC supported scientist and Honorary Lecturer at RCSI, has recently published a study describing a new way to grow cancer cells in the lab. Traditionally, researchers grow cancer cells in the flasks on the flat surface. This is not the way cells grow in the human body. Dr Piskareva in collaboration with Dr Curtin and Prof O’Brien has designed a new way to grow cancer cells that recreate their growth in 3 dimensions as in the human or mice body. They used special cotton wool like sponges as a new home for cancer cells and populated them with cancer cells. At the next step, they gave cells the drug at the different amount and checked what happened. In this system, cells responded only to the drug at doses used in the clinic or mice models.
This new strategy to grow cells on sponges should help to understand cancer cell behaviour better and accelerate the discovery and development of new effective drugs for neuroblastoma and other cancers. This, in turn, will make the outlook for little patients better and improve their quality of life.
Our group is a drug discovery lab currently working on the development of a novel Fc gamma receptor IIa inhibitors. FcgRIIa is a low affinity receptor for Fc portion of immunoglobulin G (IgG) and is implicated in a variety of conditions that are still mainly untreatable, such as rheumatoid arthritis, lupus, immune thrombocytopenia, sepsis. FcgRIIa is widely expressed by human innate immune cells, and is the only Fc gamma receptor found on human platelets.
Mainly over-stimulation of the FcgRIIa receptor in these conditions that leads to the progression of the disease. For example, in sepsis the platelets get activated via FcgRIIa in response to bacteria present in the blood, which results in thrombocytopenia and disseminated immune coagulopathy. This causes, not only internal haemorrhage but also formation of blood clots that block peripheral blood vessels leading to sepsis-associated limb loss, heart attacks and/or strokes. Using a targeted approach, such as pharmacophore modelling, our group has developed a small molecule compound that effectively blocks FcgRIIa-mediated platelet aggregation in vitro. In agreement with the chosen targeted approach, this compound was shown to bind to the FcgRIIa directly and possesses specificity for the FcgRII subgroup of the Fcg receptors.
Ultimately, this compound has a great potential to be used for treatment of other FcgRIIa-mediated auto-immune conditions, such as rheumatoid arthritis, lupus and an array of immune thrombocytopenia conditions.
