I haven't been able to find a link to the full version, shame as sounds interesting - including the bit on the new data mining tool!

... ERVs exerted a significant influence on the immune response, a mechanism that may partially contribute to the heterogeneity seen in human immune responses to retroviral infections. Secondly, a requirement for specific antibodies was shown in the control of ERVs. In a range of mice displaying distinct deficiencies in antibody production, products from the intestinal microbiota potentially induce ERV expression. Subsequent recombinational correction of a defective murine leukaemia virus (MLV) results in the emergence of infectious virus. In the long term, this leads to retrovirus-induced lymphomas and morbidity. ERVs, therefore, provide a potential link between the intestinal microbiota and a range of pathologies, including cancer. Finally, a new computational tool, REquest, was developed for use in the above studies. REquest allows the mining of retroelement (RE) and ERV expression data from the majority of commercially available human and murine microarray platforms and allows rapid hypothesis testing with publicly available data.
