Disclosed are an antibody combination for one-step screening and/or diagnosis of clonal diseases and application thereof. The antibody combination includes eight groups of antibodies, and is a set of flow cytometry detection panels for one-step screening and/or diagnosis of clonal diseases, and 5-tube parallel is used for one sample, the first group of antibodies and the second group of antibodies are used for samples in different flow cytometry tubes, the third group of antibodies and the sixth group of antibodies are used for samples in the same flow cytometry tube, the fourth group of antibodies and the seventh group of antibodies are used for samples in the same flow cytometry tube, and the fifth group of antibodies and the eighth group of antibodies are used for samples in the same flow cytometry tube.

The application is to antibodies which have been labelled with polyenzymes (multiple enzymes), specifically polyperoxidases, for use in direct immunohistochemical assays of tissues. The antibodies used diagnostically may also be antibodies which are used therapeutically.

Immunostimulatory fusion molecules that include an immune cell targeting moiety and a cytokine molecule, pharmaceutical and formulations thereof, and methods of using and making the same, are disclosed.

The present invention relates to improved methods of suppressing and/or preventing an undesired immune response comprising the use of CD83. In some embodiments, CD83 is coadministered to a subject with at least one other immunosuppressive compound. Methods are also provided for generating tolerogenic dendritic cells and regulatory T cells. These cells can be used in vitro to produce additional cells for therapeutic purposes or they can be used in vivo to suppress and/or prevent an undesired immune response. Methods of the invention can be used to prevent or reduce the severity of autoimmune diseases and can also be used to induce tolerance to at least one therapeutic composition, such as a therapeutic protein or transplanted tissue.

The present invention relates to compositions and methods relating to chimeric antigen receptor (CAR) polypeptides and methods relating thereto. In one embodiment, the present invention relates to engineered cells having chimeric antigen receptor polypeptides directed to at least two targets. In another embodiment, the present invention relates to engineered cells having chimeric antigen receptor polypeptides and an enhancer moiety.

In the field of immunotherapy, a chimeric antigen receptor (CAR) specific for-human CD45RC. Also, the immune cells expressing this CAR and the use thereof as a medicament. In particular, the use of this CAR for preventing or treating CD45RC.sup.high-related diseases (including autoimmune diseases, undesired immune responses, monogenic diseases, lymphoma or cancer), or graft-versus-host disease (GVHD).

The present invention relates to a method of using a receptor (e.g., chimeric antigen receptor—CAR) that activates an immune response upon binding a cancer cell ligand in conjunction with a target-binding molecule that targets a protein or molecule for removal or neutralization to generate enhanced anti-cancer immune cells. The present invention also relates to engineered immune cells having enhanced therapeutic efficacy and uses thereof.

Compositions and methods are described for stabilizing a radio-iodinated monoclonal IgG antibody for up to 17 days against radiolytic decomposition. The stabilized radiolabeled murine antibody binding the CD45 antigen expressed on various forms of lymphomas is useful as a radio-therapeutic and diagnostic agent in the treatment of human malignancies of hematopoietic origin, including lymphomas.

The present disclosure is directed, in some embodiments, to methods and compositions of comprising a cell having a non-internalizing receptor, and a nanoparticle surface-modified with a ligand that binds to the non-internalizing receptor.

Synthesis and pharmaceutical compositions of antibody-functionalized nanovesicles encapsulating ion channel knockout siRNA, and methods of treating autoimmune diseases associated with increased expression and/or hyperactivity of T cells by selectively targeting memory T cells with the nanoparticles, which deliver their siRNA cargo into the cytosol of the T.sub.M cell thus reducing ion channel expression and decreasing Ca.sup.2+ influx.
