Journal ArticleDOI
Tumor-specific T cell activation by recombinant immunoreceptors: CD3 zeta signaling and CD28 costimulation are simultaneously required for efficient IL-2 secretion and can be integrated into one combined CD28/CD3 zeta signaling receptor molecule.

TL;DR: T cells grafted with the combined CD28/CD3ζ signaling receptor secreted high amounts of IL-2 upon Ag binding without exogenous B7/CD28 costimulation, demonstrating that both MHC-independent cellular activation and CD28costimulation for complete T cell activation can be delivered by one recombinant receptor molecule.
Journal ArticleDOI
T Cell Activation by Antibody-Like Immunoreceptors: Increase in Affinity of the Single-Chain Fragment Domain above Threshold Does Not Increase T Cell Activation against Antigen-Positive Target Cells but Decreases Selectivity
TL;DR: Rec recombinant immunoreceptors of higher affinity do not necessarily induce a more potent activation of T cells than low affinity immunoreCEPTors, but the higher affinity immunoresceptors exhibit less discrimination between target cells with high or low Ag expression levels.
Journal ArticleDOI
Epstein Barr virus–specific cytotoxic T lymphocytes expressing the anti-CD30ζ artificial chimeric T-cell receptor for immunotherapy of Hodgkin disease
Barbara Savoldo,Cliona M. Rooney,Cliona M. Rooney,Antonio Di Stasi,Hinrich Abken,Andreas Hombach,Aaron E. Foster,Lan Zhang,Helen E. Heslop,Helen E. Heslop,Malcolm K. Brenner,Malcolm K. Brenner,Gianpietro Dotti,Gianpietro Dotti +13 more
TL;DR: EBV-CTLs expressing both a native and a chimeric antigen receptor may have added value for treatment of HD, and could be costimulated by EBV-infected cells and produce antitumor effects even against EBV(-)/CD30(+) tumors.
Journal ArticleDOI
Adoptive immunotherapy with genetically engineered T cells: modification of the IgG1 Fc 'spacer' domain in the extracellular moiety of chimeric antigen receptors avoids 'off-target' activation and unintended initiation of an innate immune response.
TL;DR: It is revealed that CARs with Fc spacer domain bind to IgG Fc gamma receptors (FcγRs), thereby unintentionally activating innate immune cells, including monocytes and natural killer cells, which consequently secrete high amounts of pro-inflammatory cytokines.
Journal Article
Chronic inflammatory bowel disease and cancer
TL;DR: The histologic evidence of dysplasia was shown to be a strong indicator of underlying carcinoma or developing malignant transformation, and the role of surveillance programs for the early detection of ulcerative colitis associated colorectal cancer at a curable stage is still under debate.
