MSc in Applied Experimental and Clinical Immunology.

To effectively study antiviral immunity, we employ the use of multiple in vivo models of viral infection. Currently my research focuses on the pathogen Cytomegalovirus (CMV).

CMV is a fairly ubiquitous β-Herpesvirus infecting approximately 50-80% of the world's population where the infection will remain asymptomatic in immuno-competent individuals. However in immune-compromised individuals such as HIV and AIDS patients, post-transplant recipient patients and during pregnancy, infection can cause morbidity and mortality. Further congential CMV infection can result in infants born with blindness, mental retardation and is the leading cause of congenital deafness. The significant area of my research is to study the immune responses to the virus within the mucosa of infected individuals in organs such as the Salivary Glands, a key area which we have identified that allows the virus to persist and replicate, and how the virus has developed immune escape mechanisms that promotes persistent infection. We have recently discovered using the MCMV model of infection that the immune regulatory cytokine IL-10 (which has been shown to suppress antiviral immunity (Humphreys et al, J Exp Med, 2007, Jones et al, J Immunol, 2010)) is produced by T-cells in both mouse and human mucosa which in turn is induced by IL-27. This then promotes viral persistence and viral shedding as a result of a suppressive response upon antiviral immunity (Clement et al PLoS Pathogens 2016).

Another area of my research is to identify the exact mechanisms that drive this cytokine induced antiviral immunity and how these cytokines can have both protective and pathological effects during infection (Clement & Humphreys, Front Immunol, 2019). We have identified an immune protein interferon-induced transmembrane protein 3 (ifitm3) that can restrict viral pathogenensis. The absence of such protein dramatically impacts on organ pathology as driven by the inflammatory cytokine IL-6 (Stacey, Clement et al, J Clin Invest, 2017). This has important implications in understanding how you can therapeutically target infected individuals with anti-inflammatory agents. This is especially important in ifitm3 as natural genetic polymorphisms which reduce the protective function of ifitm3 have been identified within specific human subsets.
