    Human papilloma virus positive (HPV+) tumors represent a large proportion of anal, vulvar, vaginal, cervical and head and neck squamous carcinomas (HNSCC) and late stage invasive disease is thought to originate from a premalignant state. Cyclic dinucleotides that activate STimulator of INterferon Genes (STING) have been shown to cause rapid regression of a range of advanced tumors. We aimed to investigate STING ligands as a novel treatment for papilloma. We tested therapies in a spontaneous mouse model of papilloma of the face and anogenital region that histologically resembles human HPV-associated papilloma. We demonstrate that STING ligands cause rapid regression of papilloma, associated with T cell infiltration, and are significantly more effective than Imiquimod, a current immunotherapy for papilloma. In humans, we show that STING is expressed in the basal layer of normal skin and lost during keratinocyte differentiation. We found STING was expressed in all HPV-associated cervical and anal dysplasia and was strongly expressed in the cancer cells of HPV+ HNSCC but not in HPV-unrelated HNSCC. We found no strong association between STING expression and progressive disease in non-HPV oral dysplasia and oral pre-malignancies that are not HPV-related. These data demonstrate that STING is expressed in basal cells of the skin and is retained in HPV+ pre-malignancies and advanced cancers, but not in HPV-unrelated HNSCC. However, using a murine HNSCC model that does not express STING, we demonstrate that STING ligands are an effective therapy regardless of expression of STING by the cancer cells

    Sacred turf: the Wimbledon tennis championships and the changing politics of Englishness

    © 2015 Taylor & Francis. This article is about ‘Wimbledon’, widely celebrated – not least in its own publicity material – as the world’s premier tennis tournament. It examines ‘Wimbledon’ essentially as a text (hence the inverted commas), viewed politically and historically. In this context, ‘Wimbledon’ is seen as a signifier of a certain kind of Englishness, carefully adapted to meet changing social and economic circumstance. Loose parallels are drawn between the cultural trajectory of ‘Wimbledon’ and that of the British royal family. The transmutations of ‘Wimbledon’ as a tennis championship are also seen as reflecting Britain’s decline as a world power during the twentieth century

    Translating FSP into LOTOS and Networks of Automata

    International audienceMany process calculi have been proposed since Robin Milner and Tony Hoare opened the way more than 25 years ago. Although they are based on the same kernel of operators, most of them are incompatible in practice. We aim at reducing the gap between process calculi, and especially making possible the joint use of underlying tool support. FSP is a widely-used calculus equipped with LTSA, a graphical and user-friendly tool. LOTOS is the only process calculus that has led to an international standard, and is supported by the CADP verification toolbox. We propose a translation from FSP to LOTOS. Since FSP composite processes are hard to encode into LOTOS, they are translated into networks of automata which are another input language accepted by CADP. Hence, it is possible to use jointly LTSA and CADP to validate FSP specifications. Our approach is completely automated by a translator tool we implemented
