With a growing aging population, clinical and medical science is challenged with a range of age-related diseases, which it is compelled to try to address. These diseases include particular manifestations of infections, neurodegeneration, cancer, autoimmunity and other immunopathologies. At the heart of these diseases is aberrant immunity, in the form of excessive inflammation and immune dysregulation which culminate in inefficiency of both active immunity and immune homeostasis. Chronic stimulation of the adaptive immune response (T and B cells) by persistent infections including cytomegalovirus and Epstein-Barr virus, and a resulting systemic (often low-grade) inflammatory response, gives rise to populations of cells that function incorrectly (being terminally-differentiated and/or senescent) and are less easily switched off when no longer required. Being able to identify such cell populations in aging individuals at risk of such diseases would allow treatments to be better designed, targeted and tailored. These treatments include vaccination, immunotherapies (such as for cancer), and homeostatic cytokines. This project will examine human T and B cells, and their responses to a panel of key antigens, across a wide range of ages. The antigens include those from viruses, bacteria, fungi, and tumours, as well autoantigens. The methods to be undertaken include: 1.ELIspot assays to enumerate cells responding by cytokine secretion (gamma-interferon, IL-17, IL-5) at the single cell level, to antigenic stimuli, 2.multiparameter flow cytometry for surface and intracellular markers of phenotype and activation, 3.ELISA to measure antibody levels .The study will be highly collaborative, involving clinicians and scientists across Newcastle. An extensive training package is provided, together with specialist supervisory support, in a great research environment.
