Inflammatory bowel disease (IBD) is characterized by very severe intestinal inflammation associated with extra-intestinal manifestations. One of the most critical ones is bone destruction, which remains a major cause of morbidity and a risk factor for osteopenia and osteoporosis in IBD patients. In various mouse models of IBD, we and other have demonstrated concomitant bone loss due to a significant increase in osteoclast activity.

Whole-genome analysis of azoospermic men has identified a number of candidate genes, such as the X-linked testis-expressed 11 (TEX11) gene.

Methods: To investigate this unexplained Th17-biased differentiation, we focused on understanding the immunobiology of B27-rat naive CD4 T cells (Tn).
Results: We observed that neutrally stimulated B27-rat Tn developed heightened Th17 profile even before disease onset, suggesting an intrinsic proinflammatory predisposition.
