Abstract: Human or humanized tissues and organs suitable for transplant are disclosed herein. Gene editing of a host animal provides a niche for complementation of the missing genetic information by donor stem cells. Editing of a host genome to knock out or disrupt genes responsible for the growth and/or differentiation of a target organ and injecting that animal at an embryo stage with donor stem cells to complement the missing genetic information for the growth and development of the organ. The result is a chimeric animal in which the complemented tissue (human/humanized organ) matches the genotype and phenotype of the donor. Such organs may be made in a single generation and the stem cell may be taken or generated from the patient's own body. As disclosed herein, it is possible to do so by simultaneously editing multiple genes in a cell or embryo creating a “niche” for the complemented tissue.

Abstract: An optical fiber package is described comprising a light transmitting core having a core diameter, a coating layer surrounding the core, and wherein the amount of chlorine in the light transmitting core region is homogeneous and comprises at least 3000 ppm. The fiber package is such that the optical fiber core exhibits a reduction in the hydrogen induced attenuation losses. A method for fabricating the optical fiber package is also disclosed.

Abstract: The present invention is directed to mammalian bi-specific T cells and methods for using these bi-specific T cells. More specifically, the invention relates to a method of controlling administration of cancer antigen to a subject by providing bi-specific T cells that express a viral antigen T cell receptor and a cancer antigen-specific chimeric receptors and triggering their activation by also administering antigen-presenting T-cells which express viral antigen. These bi-specific T cell clones are a source of effector cells that persist in vivo in response to stimulation with viral antigen, leading to long-term function after their transfer to patients with cancer and autoimmune diseases.

Abstract: The present invention is directed to universal T cells and their use in treating diseases and other physiological conditions. More specifically, the present invention is directed to universal T cells and their use in treating treating B-lineage acute lymphoblastic leukemia (B-ALL) in particular and malignancy in general. The universal T cells contain (i) nucleic acid encoding a chimeric antigen receptor (CAR) to redirect their antigen specificity and effector function and (ii) nucleic acids encoding shRNA and/or siRNA molecules to down-regulate cell-surface expression of T cell classical HLA class I and/or II genes to avoid recognition by recipient T cells. The universal T cells may also contain a nucleic acid encoding a non-classical HLA gene, such as an HLA E gene to enforce expression of HLA E genes and/or an HLA G gene to enforce expression of HLA G genes, to avoid recognition by recipient NK cells. The universal T cells may further contain a nucleic acid encoding a selection-suicide gene.

Abstract: The present invention is directed to mammalian T cells and methods for using these T cells. More specifically, the invention relates to viral specific T cells that express an endogenous viral antigen receptor, a chimeric anti-tumor receptor and the chemokine receptor CCR7. These T cells are a source of effector cells that persist in vivo in response to stimulation with viral antigen, leading to long-term function after their transfer to patients with cancer and autoimmune diseases and that are able to traffic to lymph nodes and sites of minimal residual disease.

Abstract: Methods for amplifying expression of interfering RNA (RNAi), and preferably siRNA or shRNA, using a RNAi (si/shRNA)-expressing concatamer, are disclosed. The methods are useful for modulating, including down-regulating and/or inhibiting, expression of a target gene in cells, including mammalian cells.
