Disclosed are invariant natural killer T (iNKT) cells engineered using hematopoietic stem and progenitor cells (HSPCs) and methods of making and using thereof. Specifically, the engineered cells iNKT are genetically modified to contain at least one exogenous invariant natural killer T cell receptor (iNKT TCR) nucleic acid molecule. Further disclosed are iNKT TCR nucleotide sequences and codon optimized sequences for expression.

The present disclosure relates to genetically modified T-cells to secrete broadly neutralizing antibodies against HIV, and methods of preparing and uses thereof.

The presently disclosed subject matter provides for methods and compositions for treating a neoplasia (e.g., multiple myeloma). It relates to chimeric antigen receptors (CARs) that specifically target Fc Receptor-like 5 (FcRL5), e.g., domain 9 of FcRL5, and immunoresponsive cells comprising such CARs. The presently disclosed FcRL5-targeted CARs have enhanced immune-activating properties, including anti-tumor activity.

This document provides methods and materials for generating GABAergic neurons in brains. For example, methods and materials for using nucleic acid encoding a NeuroD1 polypeptide and nucleic acid encoding a Dlx2 polypeptide to trigger glial cells (e.g., NG2 glial cells or astrocytes) within the brain (e.g., striatum) into forming GABAergic neurons (e.g., neurons resembling medium spiny neurons such as DARPP32-positive GABAergic neurons) that are functionally integrated into the brain of a living mammal (e.g., a human) are provided.

Provided herein is a modular polycistronic vector system, such as for the genetic reprogramming of cells to express one or more antigen receptors. The modular characteristic of the system allows for exchange of one or more cistrons in addition to one or more components within particular cistrons. In specific embodiments, the modularity of the system allows exchange of components of a chimeric antigen receptor, such as exchange of costimulatory domains, scFvs, hinges, signaling domains, and so forth.

This disclosure provides modified cytosine deaminases (CDs). The disclosure further relates to cells and vector expressing or comprising such modified CDs and methods of using such modified CDs in the treatment of disease and disorders.

The present invention contemplates mRNA, episomal and retroviral genomic gene therapy based short-term, intermediate or long-term vaccine, immunization, immune protection or cancer—that can also be administered as a retroviral genomic gene therapy both in vivo and ex vivo—method to provide epithelial and hematological protection to humans to protect against cancer especially carcinomas, pandemic and non-pandemic viruses, bacterial infections, allergens or the cause of allergic reactions, systemic pathological conditions, cancer and anti-biowarfare agents (e.g. natural and unnatural viruses and toxins) where mucosal immunity and for some diseases hematological immunity is achieved through mRNA, episomal or genomic integrated lentiviral and gammaretroviral vector expression of dimeric immunoglobulin A1 (dIgA1), dimeric immunoglobulin A2 (dIgA2) and engineered variants. Additionally, in some embodiments a method to agglutinate cancers including carcinomas and hematological cancers to prevent metastasis with polymeric immunoglobulin A and dimeric immunoglobulin A and engineered variants. The present invention provides methods, immunoglobulin compositions and vector constructs to express potent immunoglobulins that are derived from human blood of a human currently infected with, affected by, exposed to or recovered from any of a wide range of allergens or the cause of allergic reactions, pathogens (including, viruses, virus mutants, bacterial infections and fungi) and systemic pathological ailments (including cancer and other disorders), developed from phage display technology or mice or other non-human vertebrates with engineered immune systems or humanized immune systems, transgenic mice or chimeric antibodies a fusion of non-human vertebrates (e.g. mouse or rabbit), mouse antibody V-regions, human antibodies. The immunoglobulin compositions include the heavy chain variable, diversity and joining (VDJ or Variable Heavy Region genes) segment immunoglobulin DNA and/or polypeptide sequence from humans identified to have therapeutically relevant affinity immunoglobulins against the antigen, protein or proteins of interest and either to use the exact immunoglobulin heavy chain and light chain polypeptide sequences identified from the B-cell that produced them or to modify or engineer some of the immunoglobulin heavy chain and light chain constant domains to modulate effector functions. Although, ideally there are no changes made to the immunoglobulins light and heavy chains as identified from the B-cell that produced them. Modifications may occur at the Hinge region, Constant Heavy 2 (C.sub.H2) domain and Constant Heavy 3 (C.sub.H3) domain for the immunoglobul

A cell modified for obtaining increased proliferative capacity, decreased aging and enhanced regenerative capacity, its modification involving HOXB7 overexpression obtained using a gene vector that can insert the coding sequence into the cell, thereby affording increased protein production.

Methods for producing new neurons in the brain in vivo are provided according to aspects of the present invention which include introducing NeuroD1 into a glial cell, particularly into a reactive astrocyte or NG2 cell, thereby “converting” the reactive glial cell to a neuron. Methods of producing a neuronal phenotype in a glial cell are provided according to aspects of the present invention which include expressing exogenous NeuroD1 in the glial cell, wherein expressing exogenous NeuroD1 includes delivering an expression vector, such as a viral expression vector, including a nucleic acid encoding the exogenous NeuroD1 to the glial cell.

Provided herein are methods for transducing a plurality of cells in a composition of cells, such as a population of lymphocytes, containing viral particles. In some aspects, provided methods and reagents for the transduction of cell populations involve binding of agents to a molecule on the surface of the cells. In some cases, the reagents are multimerization reagents and the one or more agents are multimerized by reversibly binding to the reagent. In some aspects, the multimerized agent can provide for transduction and/or expansion or proliferation or other stimulation of a population of cells, and then such agents can be removed by disruption of the reversible bond. Also provided are compositions, apparatus and methods of use thereof.
