The invention provides methods and compositions for the modulation of systemic immune responses by transplantation of hematopoietic stem cells transduced with genes encoding antigens and antigen presenting cell regulatory molecules. The invention includes bi-cistronic lentiviral expression vectors adapted for antigen expression in antigen presenting cells for use in DNA vaccines directed against pathogens and tumor antigens as well as for the treatment of autoimmune disease and for the establishment of antigen tolerance.

Disclosed herein are antigen-binding molecules, such as antibodies, that specifically recognize a portion of the EGFR C-terminal (intracellular) regulatory domain that interacts with one or more regulatory molecules (such as Suppressor of Cytokine Signaling (“SOCS”) proteins). In certain normal or neoplastic cells and / or tissues, this region is inaccessible to the disclosed antigen-binding molecules. Thus, such antigen-binding molecules are useful at least to interrogate the regulated state of EGFR, predict the response of a cancer patient to EGFR inhibitor therapies, and / or predict the aggressiveness of neoplasms.

The present invention relates to a novel isolated whitefly ecdysone receptor polypeptide. The invention also relates to an isolated nucleic acid encoding the whitefly ecdysone receptor polypeptide, to vectors comprising them and to their uses, in particular in methods for modulating gene expression in an ecdysone receptor-based gene expression modulation system and methods for identifying molecules that modulate whitefly ecdysone receptor activity.

A targeted composition comprising a modulation molecule, such as an siRNA oligo or a small molecule, and a translocation peptide is disclosed. Methods of making and using the composition are also disclosed. The disclosed composition can be employed in a variety of therapeutic and research applications, in which it is desirable to deliver a modulation molecule, such as an siRNA oligo or a small molecule, to a particular site, such as a site of vascularization. In one aspect of a composition of the invention, a translocation peptide directs the modulation molecule to a selected location, and a modulation molecule modulates the expression or activity of a selected target disposed at or near the selected location.

The invention relates to methods and compositions for transferring genetic material into a cell and regulating expression of the transferred genetic material. Included in the invention are methods for inducing the regulated expression of an exogenous nucleic acid introduced in a cell by the use of a regulator molecule that binds to a protein encoded by a second nucleic acid that has also been introduced into the cell.

Disclosed is agroup of chimeric antigen receptors (CARs) consisting of two, three or four CAR molecules, wherein the members of the group of CARs can be different or identical in their amino acid sequences to one another, and wherein each of the CAR molecules of the group comprise at least a transmembrane domain and an ectodomain comprising either an antigen binding moiety or a binding site to which another polypeptide is able to bind, wherein the another polypeptide comprises an antigen binding moiety; wherein each CAR molecule of the group comprises at least one dimerization domain, wherein this dimerization of a pair of dimerization domains is either induced by a regulating molecule and optionally reduced by another regulating molecule, or occurs in the absence of a regulating molecule and is reduced by a regulating molecule, and wherein the ectodomain of each CAR molecule of the group in its prevalent conformation is free of cysteine amino acid moieties which are able to form intermolecular disulphide bonds with other CAR molecules of the group, respectively, and wherein the antigen binding moieties of the CAR molecules of the group and of the other polypeptides being able to bind to the CAR molecules of the group are either specific for one target antigen or for a non-covalent or a covalent complex of different target antigens.

Application to an allograft or xenograft of a low strength electric field network (LSEN) together with an immuno-suppressive drug, gene and siRNA or other gene-based therapy is used to mediate the immune responses within an donor organ, tissue or cells, to prevent the acute and chronic rejection and to induce true tolerance, The gene(s) is locally transferred ex vivo in the time interval between harvest and implantation of allografts or xenografts before the implantation to introduce the long-term over expression of immunosuppressive and / or modulative molecules, or for down regulating alloreactive molecules in the donor organ, tissue or cells only and not in the recipient's whole body system.

The invention provides human regulatory molecules and the polynucleotides which identify and encode them. The invention also provides expression vectors, host cells, agonists, antibodies and antagonists. The invention further provides methods for diagnosing and treating disorders associated with expression of human regulatory molecules.

Provided are a modified laminin having a cell-growth regulatory molecule bound to at least one site selected from the α chain N-terminus, the α chain C-terminus, the β chain N-terminus and the γ chain N-terminus of laminin or a heterotrimeric laminin fragment, a method for culturing cells in the presence of the modified laminin, a method for establishing iPS cells in the presence of the modified laminin, and a culture substrate coated with the modified laminin. Human stem cells cultured in a xeno-free environment with the use of the modified laminin of the present invention can be provided as highly safe human stem cells applicable to regenerative medicine.

The present invention relates to a gene regulating the number of nodules of nodule plants and its application in efficient nitrogen fixation. The inventors cloned a new gene for the first time: Rac1 gene. Functional analysis showed that the gene or its regulatory molecules were closely related to the number of nodules in rooted plants. Therefore, the gene can be applied to plant improvement to obtain plants with altered root nodule traits and nitrogen fixation traits.

A group of chimeric antigen receptors (CARs) having two, three or four CAR molecules,wherein the members of the group of CARs can be different in their amino acid sequences, andwherein each of the CAR molecules of the group includes at least a transmembrane domain and an ectodomain comprising either an antigen binding moiety or a binding site to which another polypeptide is able to bind, wherein the polypeptide comprises an antigen binding moiety;wherein each CAR molecule of the group includes at least one dimerization domain, wherein this dimerization of a pair of dimerization domains is either induced by a regulating molecule and optionally reduced by another regulating molecule, or occurs in the absence of a regulating molecule and is reduced by a regulating molecule, andwherein the antigen binding moieties of the CAR molecules of the group specific for one target antigen.
