Abstract: The present invention relates to immunoglobulin single variable domain sequences that are directed against (as defined herein) OX40L, as well as to compounds or constructs, and in particular proteins and polypeptides, that comprise or essentially consist of one or more such immunoglobulin single variable domain sequences. In particular these immunoglobulin single variable domain sequences can block binding of OX40L to OX40. The immunoglobulin single variable domains, compounds and constructs can be used for prophylactic, therapeutic or diagnostic purposes, such as for the treatment of inflammatory disease and/or disorder such as e.g. asthma, allergic asthma, chronic colitis, Crohn's disease, inflammatory bowel disease, and/or arthrosclerosis.

Abstract: The present invention relates to a chimeric receptor capable of signaling both a primary and a co-stimulatory pathway, thus allowing activation of the co-stimulatory pathway without binding to the natural ligand. The cytoplasmic domain of the receptor contains a portion of the 4-1BB signaling domain. Embodiments of the invention relate to polynucleotides that encode the receptor, vectors and host cells encoding a chimeric receptor, particularly including T cells and natural killer (NK) cells and methods of use.

Abstract: The present invention relates to a substance specific to human PD-1 comprising a part that recognizes human PD-1, a part that recognizes a membrane protein in cell membrane of human PD-1-expressing cells, and linkers. Since the substance specific to human PD-1 selectively can recognize human PD-1 and a membrane protein on cell membrane of human PD-1-expressing cells and can transmit inhibitory signal of human PD-1, it is useful for therapy and/or prevention of diseases caused by immunopathy.

Abstract: The present invention relates to an ICOS binding protein, or antigen binding portion thereof that is an agonist human ICOS and does not induce complement, ADCC, or CDC when placed in contact with a T cell in vivo and methods of treating cancer, infectious disease and/or sepsis with said ICOS binding protein or antigen binding portion thereof. Further the ICOS binding proteins or antigen binding portions thereof of the present invention are capable of activating a T cell when placed in contact with said T cell; stimulating T cell proliferation when placed in contact with said T cell and/or inducing cytokine production when placed in contact with said T cell. The present invention relates to ICOS binding proteins or antigen binding portions thereof comprising one or more of: SEQ ID NO:1; SEQ ID NO:2; SEQ ID NO:3; SEQ ID NO:4; SEQ ID NO:5; and/or SEQ ID NO:6.

Abstract: The invention provides an isolated and purified nucleic acid sequence encoding a chimeric antigen receptor (CAR) directed against B-cell Maturation Antigen (BCMA). The invention also provides host cells, such as T-cells or natural killer (NK) cells, expressing the CAR and methods for destroying multiple myeloma cells.

Abstract: Methods are provided to enhance the efficacy of antibody therapy directed to tumor cells.

Abstract: The present invention provides soluble CTLA4 mutant molecules which bind with greater avidity to the CD80 and/or CD86 antigen than wild type CTLA4 or non-mutated CTLA4Ig. The soluble CTLA4 molecules have a first amino acid sequence comprising the extracellular domain of CTLA4, where certain amino acid residues within the S25-R33 region and M97-G107 region are mutated. The mutant molecules of the invention may also include a second amino acid sequence which increases the solubility of the mutant molecule.

Abstract: This invention relates to recombinant CTLA-4 proteins, e.g., soluble CTLA-4 or CTLA-4 fusion toxins, and methods for making and using them.

Abstract: The present invention provides compositions and methods for regulating the specificity and activity of T cells. In one embodiment, the invention provides a type of chimeric antigen receptor (CAR) wherein the CAR is termed a “KIR-CAR” which is a CAR design comprising a component of a receptor naturally found on natural killer (NK) cells. In one embodiment, the NK receptor includes but is not limited to a naturally occurring activating and inhibitory receptor of NK cells known as a killer cell immunoglobulin-like receptor (KIR).

Abstract: The present invention relates to an ICOS binding protein or antigen binding portion thereof that is an agonist to human ICOS and does not induce complement, ADCC, or CDC when placed in contact with a T cell in vivo and methods of treating cancer, infectious disease and/or sepsis with said ICOS binding protein or antigen binding portion thereof. Further the ICOS binding proteins or antigen binding portions thereof of the present invention are capable of activating a T cell when placed in contact with said T cell; stimulating T cell proliferation when placed in contact with said T cell and/or inducing cytokine production when placed in contact with said T cell.

Abstract: The invention provides an anti-CTLA4 antibody which inhibits the binding of CTLA4 to human B7, in particular, it inhibits binding of CTLA4 to human B7.1 and/or human B7.2. Specific antibodies are provided with specific variable region sequences as well as compositions comprising such antibodies for use in treating disease.

Abstract: Provided is a prophylactic, symptom progress-suppressive, and/or therapeutic agent for an autoimmune disease. The agent lowers the risk of infections and reduces the burden of administration to patients. The prophylactic, symptom progress-suppressive, and/or therapeutic agent includes a PD-1 agonist as an active ingredient and is administered (a) 1 to 10 times within one month from the first administration, (b) in a total PD-1 agonist dose of 20 to 1250 ?g/kg, and (c) without requiring administration for at least 3 months after the last administration.

Abstract: Human antibodies, preferably recombinant human antibodies, both humanized and chimeric, which specifically bind to human OX40 are disclosed. Preferred antibodies have high affinity for OX40 receptor and activate the receptor in vitro and in vivo. The antibody can be a full-length antibody or an antigen-binding portion thereof.
