Anne Op de beeck obtained a PhD degree at the Universit\u00e9 Libre de Bruxelles in 1996. During her PhD, she was the first to describe the cytostatic property of the parvoviral protein NS1 and to unravel the underlying mechanisms, paving the way in the emerging field of viral interference with the cell cycle. She further worked as a postdoctoral fellow in the laboratory of Jean Dubuisson at the Institut de Biologie de Lille\/Institut Pasteur de Lille, France. Her post doc was devoted to the characterization of the process of assembly of the envelope of Hepatitis C and of Yellow Fever Viruses and to the study of the complex process of entry of hepatitis C virus. In 2004, she obtained a tenured position as researcher at the Centre National de la Recherche Scientifique (CNRS), France.<\/p>

She is currently detached from the CNRS and holds an appointment as Professor of the Faculty of Medicine, Universit\u00e9 Libre de Bruxelles.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

The triggering of type 1 diabetes depends on environmental factors that interact with predisposing genes to induce the autoimmune assault against \u03b2-cells. Among the potential environmental factors, epidemiological, clinical and pathology studies in humans support the implication of viral infections, particularly by enteroviruses (for example, Coxsackievirus), as triggers for the development of type 1 diabetes. In line with this, many candidate genes for type 1 diabetes regulate antiviral responses in both \u03b2-cells and the immune system.<\/p>

\u00a0The main research focus of the Op de beeck group are the characterization of virus-induced \u03b2-cell dysfunction and death and the identification of factors involved in \u03b2-cell permissiveness to viral infection.<\/p>

\u00a0In collaboration with Eizirik, Op de beeck unveiled the mechanisms of Coxsackieviruses induced beta cell death, the powerful antiviral response of pancreatic alpha cells to viral infection and the key role played by IFN-alpha in the early steps of type 1 diabetes. She also recently described that Coxsackievirus tailors the unfolded protein response to ER stress to favor viral amplification in pancreatic \u03b2-cells.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
