Dr Ann Vernallis studies small proteins called cytokines. Although most people will never have heard of them, abnormal increases or decreases in cytokine levels are associated with a variety of diseases. Researchers have been interested in them for years; medical interest really took off when anti-TNF (tumour necrosis factor) treatment was developed for rheumatoid arthritis — an example of the beneficial interplay of basic and clinical sciences.

Dr Ann Vernallis is a Lecturer in the School of Life and Health Sciences at the University of Aston. She’s interested in cell signalling. As a post-doctoral fellow, she studied cytokine receptor interactions in the IL-6 family. At Aston, she’s studied the secretion of Leukemia Inhibitory Factor (LIF), the pro-inflammatory activities of lipoteichoic acid from Gram-positive bacteria and cytokine levels in patients with infections. She’s currently working on the anti-inflammatory effects of tetracyclines, and she collaborates on studies of neuron/astrocyte interactions in a neuronal stem cell model.

The case for blue skies research is made passionately by Elizabeth Oliver-Jones in The New Optimists, and with due cause. Her particular research focuses around the study of early cell interactions in amphibians, about the little-known molecular mechanisms by which vertebrate embryos achieve the myriad complex patterns and cell types found in the adult animal.

Such work may seem a far cry from most of our lives, perhaps something even for the politician’s knife. But (and this is a big BUT), such seemingly esoteric research by Professor Oliver-Jones and other scientists on the Xenopus (a type of aquatic frog native to sub-Saharan Africa) has established gene expression and function in a number of human diseases such as colorectal cancer, and has also provided biochemical insight into important oncogenes. Indeed, her work on amphibians is important in understanding cell signalling, and in the relationships between genes and development in many other living organisms including ourselves.

Elizabeth Oliver-Jones is a Professor in the Department of Biological Sciences at the University of Warwick. Her work is funded by the BBRSC and the Wellcome Trust, including £1.5M from the Wellcome Trust for a Xenopus Stock Centre, 2006-2011 with Dr Matt Guile at the University of Portsmouth.
