Despite the recent availability of gene-specific nucleases, such as zinc-finger nucleases (ZFNs) and transcription activator-like nucleases (TALENs), there is still a need for new tools to modify the genome of different species in an efficient, rapid, and less costly manner. One aim of this study was to apply, for the first time, engineered meganucleases to(More)
Mice transgenic for human Ig loci are an invaluable resource for the production of human Abs. However, such mice often do not yield human mAbs as effectively as conventional mice yield mouse mAbs. Suboptimal efficacy in delivery of human Abs might reflect imperfect interaction between the human membrane IgH chains and the mouse cellular signaling machinery.(More)
BACKGROUND There is an ever-increasing need of monoclonal antibodies (mAbs) for biomedical applications and fully human binders are particularly desirable due to their reduced immunogenicity in patients. We have applied a strategy for the isolation of antigen-specific B cells using tetramerized proteins and single-cell sorting followed by reconstruction of(More)
Expression of human antibody repertoires in transgenic animals has been accomplished by introducing large human Ig loci into mice and, more recently, a chimeric IgH locus into rats. With human VH, D and JH genes linked to the rat C-region antibody expression was significantly increased, similar to wild-type levels not found with fully human constructs. Here(More)
Melan-A/MART1 is a melanocytic differentiation antigen expressed by tumor cells of the majority of melanoma patients and, as such, is considered as a good target for melanoma immunotherapy. Nonetheless, the number of class I and II restricted Melan-A epitopes identified so far remains limited. Here we describe a new Melan-A/MART-1 epitope recognized in the(More)
High level of T-cell infiltration in colorectal carcinomas (CRCs) is a good prognostic indicator, but the tumor reactivity of this infiltrate (tumor infiltrating lymphocytes [TIL]) is poorly documented. This study examined the presence, phenotype and functional features of tumor-reactive lymphocytes in human CRC. Freshly dissociated TIL and T cell lines(More)
On June 7 2013 was held in Nantes, France, the international meeting ‘‘Technical advances in the generation of transgenic animals and in their applications’’ ( This biennial meeting is the fourth one of its kind to be organized by the Transgenic Rats Nantes facility (http:// The meeting was(More)
Studies have shown that an enhanced CD8+ T cell response and better tumor protection can be achieved by heterologous prime-boost vaccination in mice. Such heterologous vaccination can be more immunogenic than the homologous setting. We previously demonstrated that a listeriolysin-O (LLO)-expressing E. coli vaccine can enhance CD8-cytotoxic T cell (CTL)(More)
Recombinant, replication-deficient serotype 5 adenovirus infects the liver upon in vivo, systemic injection in rodents. This infection requires the binding of factor X to the capsid of this adenovirus. Another organ, the adrenal gland is also infected upon systemic administration of Ad, however, whether this infection is dependent on the cocksackie(More)
