van Noort, J.M. (author), Bajramovic, J.J. (author), Plomp, A.C. (author), van Stipdonk, M.J.B. (author)Several findings indicate that infectious events play a role in the pathogenesis of multiple sclerosis (MS). At the same time, T-cell autoimmunity to myelin antigens is widely believed to be crucial to the development of MS lesions. Several mechanisms have been put forward to explain the presumed link between microbial infections and myelin...article 2000

(author)The host-immune response against adenoviruses forms a major obstacle for their use as gene therapy vectors for treatment of genetic defects. None the less, they are the preferred vectors for in vivo gene transfer in experimental gene therapy protocols for cancer. In this article we demonstrate the antitumor efficacy of adenovirus-mediated...article 2000
