Compositions and methods for the therapy and diagnosis of Inflammatory Bowel Disease (IBD), including Crohn's Disease and Ulcerative Colitis, are disclosed. Illustrative compositions comprise one or more bacterial polypeptides, immunogenic portions thereof, polynucleotides that encode such polypeptides, antigen presenting cell that expresses such polypeptides, and T cells that are specific for cells expressing such polypeptides. The disclosed compositions are useful, for example, in the diagnosis, prevention and/or treatment of IBD.

T-cells useful in T-cell immunotherapy comprise a CAR, TCR and/or nucleic acid sequence(s) encoding a CAR and/or a TCR. The T-cells also comprise HP-NAP, an immunological equivalent fragment thereof and/or nucleic acid sequence(s) encoding HAP-NAP and/or an immunological equivalent fragment thereof. The T-cells have improved effects in immunotherapy including improved cytotoxicity, stimulation of chemokine and cytokine secretion, promoting dendritic cell maturation and recruitment and activation of innate immune cells.

The invention relates to an adenovirus comprising a nucleic acid sequence encoding a Helicobacter pylori neutrophil-activating protein (NAP) and/or a nucleic acid sequence encoding an immunologically equivalent fragment of NAP and a nucleic acid sequence encoding an immunomodulator capable of inducing an immune response in a subject. The adenovirus has enhanced clinical effects in terms of delaying tumor growth and prolonging survival.

There is provided novel peptides for use in diagnosis of CagA+ H. pylori infection or the prediction of risk for gastric cancer. The peptides bind antibodies from CagA+ H. pylori patients with high specificity and sensitivity, and can be used for example in a diagnostic kit.
