The invention relates to a method comprising a step of determining the number, concentration and/or proportion of T lymphocytes with a CD4.sup.+ CD8.sup.low phenotype and further expressing CCR6 and/or CXCR6, for (i) diagnosing, (ii) prognosing outcome of, or (iii) predicting the risk of developing a disease related to a decrease of F. prau. The invention also concerns the treatment of said disease by administering a population of these specific T lymphocytes. The Inventors have indeed identified two markers, CCR6 and CXCR6, enabling to select a population of F. prau-specific cells among CD4.sup.+ CD8.sup.low T lymphocytes, from a blood sample and without needing to assess their F. prau specificity. T lymphocytes with a CD4.sup.+ CD8.sup.low CCR6+ CXCR6+ phenotype are for example significantly decreased in IBD patients. The disease related to a decrease of F. prau is particularly an inflammatory bowel disease (IBD), such as Crohn's disease.

Provided herein are methods of stimulating or increasing the proliferation of a T.sub.reg cell, compositions including a population of T.sub.reg cells generated by these methods, and methods of treating a subject using these compositions.

Chimeric autoantibody receptors (CAARs) can include separate signaling and recognition constructs that are able to bind ligands that target autoantigens made of conventional amino acids, non-conventional amino acids, carbohydrates, or nucleic acids. Additionally, the present disclosure describes cells modified to express such constructs and the use of such constructs and/or cells in the treatment of autoimmune disease.

The present invention relates to augmenting the effects of adoptive T cell therapy, such as TVAX Immunotherapy, using adjunct treatment with an oncolytic virus, such as a vaccinia virus, to treat various types of cancer or other proliferative disorders. Immunomodulatory compounds can be used to further augment to effects of the therapy.
