Trosolwyg
I am part of the Tissue Microenvironment Group, School of Medicine, Cardiff University which is a collection of diverse and international researchers with a multidisciplinary approach to science.
My own specialist insterst involves studies of cell-derived vesicles. This is now a rapidly growing and exciting area of biology, but we have been able to establish some expertiese in this field since the early 2000's. The group has published well over 90 papers, most in relation to vesicles, and their roles in subverting immune responses, in controlling the cancer microenvironment and as potential disease biomarkers.
I am interested in understanding the mechanisms by which vesicle biogenesis and secretion is controlled, and the impact such vesicles have on the development and progression of cancer; particularly focussing on prostate cancer. Developing tools and assays to quantify nano-vesicles in biological fluid specimens is also an important aspect of the group's activities.
Although my main focus is in cancer biology, I collaborate broadly with researchers in Cardiff including those in the schools of dentistry, engineering and optometry, and interact with other Universities, on aspects including cardiovascular disease, neurodegenerative diseases and other conditions that impact our society in significant ways.

Ymchwil
We are interested in understanding how cells produce small fat-bubbles (vesicles), and why they seem to do this so extensively. Our studies focus on the role of such bubbles in changing the immediate surroundings of the cancer tissue. it seems these bubbles (exosomes) can interfere with the correct function of immune cells, they can encourage formation of blood vessels, and can hijack other neighbouring cells to behave abnormally- all of these effects assist the growth and ultimate spread of the tumour.
We can also detect exosomes in the urine and blood of cancer patients, and we are working hard on developing new methods to isolate exosomes from biological fluids, and to use these as means of discovering new indicators of disease. We have examined the complex array of protein molecules on the vesicles, and are beginning to also look at RNA-molecules, which hide inside the bubble.
Together, these studies will provide much needed information about how the cancer cells can dominate and take-over their microenvironments. Learning how to block these effects is likely to be very useful therapeutically. Pperhaps we can also use the presence of exosomes in urine/blood as future tests to support diagnoses and monitoring of cancer.
