The present invention relates to the treatment of autoimmune and allergic diseases by mucosal delivery by micro-organism, in particular Lactococcus lactic, of secreted immunodominant antigens.

A method of treating a T cell-mediated inflammatory autoimmune disease by administering to an individual in need thereof an immunogenic composition comprising a recombinant construct of a nucleic acid sequence encoding heat shock protein 90 (HSP 90), or an active fragment thereof, wherein the nucleic acid sequence is operatively linked to one or more transcription control sequences. The disease is other than insulin dependent diabetes mellitus (IDDM) or rheumatoid arthritis. The administering of the immunogenic composition results in a shift of the immune response to a Th2 response, thereby treating the disease.

The present invention provides an immunoconjugate having the formula:
T-c-E.sub.n-c-Fc.sub.n or T-c-Fc.sub.n-c-E.sub.n;
wherein, T is a single chain variable portion fragment of a monoclonal antibody (scFv) directed to a target protein, polypeptide, or fragment thereof, which is highly expressed on cancer cells; E is two or more foreign immunogenic CD8.sup.+ T cell antigenic epitopes; c is a peptide or polypeptide fragment thereof, capable of being cleaved by a specific protease; and Fc is two or more Fc portions of an IgG antibody. Nucleic acid sequences encoding the same and vectors containing said nucleic acid sequences are also provided. Methods of making the immunoconjugate, along with methods of making target cells susceptible to CTL mediated cell killing, and methods for treatment of cancers are also provided.

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.

In certain aspects, provided herein are compositions and methods for treating cancer. The methods of the present disclosure comprise administering to a subject in need thereof a NK cell expressing a CAR in combination with an antigen-binding molecule that binds to a tumor antigen, wherein the CAR-NK cell targets tumor cells through binding to the antigen-binding molecule.

The methods of the present disclosure comprise administering to a subject in need thereof a NK cell expressing a CAR in combination with an antigen-binding molecule that binds to a tumor antigen, wherein the CAR-NK cell targets tumor cells through binding to the antigen-binding molecule.

Provided are methods for activating an antigen-presenting cell and eliciting an immune response by inducing an inducible pattern recognition receptor adapter, or adapter fragment, and CD40 activity. Also provided are nucleic acid compositions comprising sequences coding for chimeric proteins that include an inducible CD40 peptide and an inducible pattern recognition receptor adapter or adapter fragment.

The invention described herein relates to methods and compositions for treating cancer in a patient, or a tumor cell, by administering an effective amount of an antibody-anti-fugetactic agent complex.
