The invention features compositions and methods useful in treating inflammation of the gut, such as inflammation associated with inflammatory bowel disease, by modulating ?? T cells (e.g., V?4+ cells). Particular embodiments include V?4+ cells expressing heterologous protein; polynucleotides containing genes contributing to functional expression of BTNL3, BTNL8, and HNF4A; methods of treating a subject using V?4+ cells or gene therapy; and methods of identifying a subject having imitations associated with inflammation of the gut. Compositions and methods of the invention can be used in the treatment of inflammation and cancer of the gut.

Compositions and methods of selectively activating Akt3 are provided.

Provided is an GARP protein antibody, and a cell comprising or expressing the GA RP protein antibody. The GARP protein antibody binds to human GARP/human TGF-?1 complex with a K.sub.D value of about 1.0E-12 or less. Also provided are a pharmaceutical combination comprising the GARP protein antibody and an immune checkpoint inhibitor and use thereof.

The disclosure provides methods for improved hematopoietic stem cell transplantations, including methods to enhance protection from graft versus host disease while maintaining effective immune responses such as graft versus tumor immune responses. The disclosure provides methods for administering, for example, hematopoietic stem and progenitor cells, regulatory T cells, and conventional T cells, wherein the conventional T cells are administered after the hematopoietic stem and progenitor cells and regulatory T cells. The disclosure also provides methods for administering, for example, hematopoietic stem and progenitor cells, regulatory T cells, and conventional T cells, wherein the regulatory T cells have not been cryopreserved prior to administration.

The present application provides antibody-TCR chimeric constructs comprising an antibody moiety that specifically binds to a target antigen fused to a TCRM capable of recruiting at least one TCR-associated signaling module. Also provided are methods of making and using these constructs.

The present disclosure relates to the in vivo prevention or treatment of hematologic malignancy relapse using a TNFR2 antagonist (an anti TNFR2 antagonist antibody) (i) for use in the prevention or treatment of hematologic malignancy relapse after allogeneic hematopoietic stem cell transplantation (AHCT) or after a treatment with lymphocytes and (ii) for use in enhancing the graft-versus-leukemia-activity (GVL activity) of a hematopoietic stem cell transplantation (HCT) or a treatment with lymphocytes.

The present invention relates to the identification of novel peptides derived from aberrant proteins involved in Type 1 Diabetes mellitus (T1D), also known as defective ribosomal products (DRiPs). In particular the invention relates to epitopes present in DRiPs of the human preproinsulin (PPI) mRNA, its representative peptides and the use thereof in diagnosis, prevention and/or treatment of T1D. Moreover, the inventions relate to antibodies and antisera against the identified epitopes and the use thereof in the diagnosis of T1D.

The present invention relates to tolerogenic mammalian dendritic cells (iDCs) and methods for the production of tolerogenic DCs. In addition, the present invention provides methods for administration of tolerogenic dendritic cells as well as particles containing oligonucleotides to mammalian subjects. Enhanced tolerogenicity in a host can be useful for treating inflammatory and autoimmune related diseases, such as type 1 diabetes.

A non-human mammalian model for human diseases or disorders comprising a non-human neutrophil depleted mammalian host engrafted with a human skin equivalent (huSE) and human immune cells.

The present invention provides, among other things, methods and compositions for modulating or treating inflammatory and autoimmune diseases, disorders, and conditions. The present invention is based, in part, on the surprising discovery that engineered regulatory T-cells characterized by constitutive STAT activity are efficacious in treating disease.
