The invention provides anti-LgR5 antibodies and methods of using the same.

Synthetic bacterial messenger RNA can be used to prepare autologous, allogenic or direct nucleic acid cancer vaccines. Cancer cells are transfected either in vitro or in vivo with mRNA obtained from DNA that encodes an immunogenic bacterial protein. An immune response to the cancer is generated from direct administration of the mRNA in vivo or administration of vaccines prepared from cancer cells in vitro.

The present disclosure provides a modified cell of leukemic origin comprising a downregulated CD47 pathway. Methods for using the modified cells in treating cancer alone, or in combination with CD47 blockade are also provided. Also provided are compositions comprising a modified cell of leukemic origin, pharmaceutical compositions and formulations thereof, and methods of producing the modified cells.

Disclosed herein are materials and methods for treating cancer. In particular, compositions for stimulating tumor immunity through modulation of MFG-E8 are provided.

A method to treat an autoimmune disease is provided. The method involves administration of interleukin-15 receptor (IL-15R) agonists in an amount effective to ameliorate a symptom of the autoimmune disease. The invention also involves a method to treat an autoimmune disease by ex-vivo expansion of CD44+CD122+Kir+ CD8+ Treg cells and administration of the CD44+CD122+Kir+ CD8+ Treg cells. Compositions comprising CD44+CD122+Kir+ CD8+ Treg cells are also provided. Methods for stimulating an immune response to an antigen are also provided.

Adenocarcinoma antigenic determinants, methods for their production and use, and broadly-specific human monoclonal antibodies reactive to the epitopes. These epitopes, which can be physically recapitulated, are conserved across a range of adenocarcinomas and are capable of eliciting an immune response in humans.

The present invention is based, in part, on cancer vaccine compositions that comprise PTEN- and p53-deficient cancer cells with activated TGFβ-Smad/p63 signaling pathway, and methods for using same to prevent and/or treat cancer.

Disclosed herein are methods for selecting cancer patients for autologous cancer vaccine therapy and methods for predicting survival of cancer patients after autologous cancer vaccine therapy comprising, measuring the level of soluble programmed cell death protein-1 (sPD-1) in the blood of the patient.

The present invention discloses immunomodulating compositions. More particularly, the present invention discloses compositions comprising an immune-modulating agent and a lectin-interactive agent, which are useful for stimulating and prolonging host immune cell responses. The compositions of the present invention are particularly useful in the treatment and/or prophylaxis of a range of conditions including pathogenic infections, autoimmune diseases, transplant rejection, graft versus host disease, allergies, inflammatory disease, as well as cancers and tumors.

The present disclosure relates to compositions and methods for treating or preventing a disease or disorder of immunoprivileged tissue. It is described herein that an immunogenic composition which induces production of memory CD4 T cells allows for the access of a therapeutic antibody to the immunoprivileged tissue.
