摘要:
Methods for inducing a population of T cells to proliferate by activating the population of T cells and stimulating an accessory molecule on the surface of the T cells with a ligand which binds the accessory molecule are described. T cell proliferation occurs in the absence of exogenous growth factors or accessory cells. T cell activation is accomplished by stimulating the T cell receptor (TCR)/CD3 complex or the CD2 surface protein. To induce proliferation of an activated population T cells, an accessory molecule on the surface of the T cells, such as CD28, is stimulated with a ligand which binds the accessory molecule. The T cell population expanded by the method of the invention can be genetically transduced and used for immunotherapy or can be used in methods of diagnosis.

Compositions for inducing a population of T cells to proliferate in vitro by activating the population of T cells and stimulating an accessory molecule on the surface of the T cells with a ligand which binds the accessory molecule are described. T cell proliferation occurs in the absence of exogenous growth factors or accessory cells. T cell activation is accomplished by stimulating the T cell receptor (TCR)/CD3 complex or the CD2 surface protein. To induce proliferation of an activated population of T cells, an accessory molecule on the surface of the T cells, such as CD28, is stimulated with a ligand which binds the accessory molecule. The T cell population expanded by the composition of the invention can be genetically transduced and used for immunotherapy or can be used in methods of diagnosis
摘要:
A method for transfecting T cells with a nucleic acid molecule comprising a gene such that the gene is expressed in the T cells is described. The T cells are stimulated and proliferating prior to introduction of the nucleic acid molecule.
摘要:
Methods for protecting a T cell from cell death are described. The methods involve contacting the T cell with an agent which augments the bcl-XL protein level in the T cell such that it is protected from cell death. The invention further pertains to methods for increasing the susceptibility of a T cell to cell death, comprising contacting the T cell with at least one agent which decreases bcl-XL protein level in the T cell. Both in vivo and in vitro methods are described.

摘要:
Methods for generating highly enriched Th1/Tc1 and Th2/Tc2 functions are described. In particular, the generation of these functions are attained by the addition of an immune suppression drug, rapamycin or a rapamycin derivative compound. In addition to enhanced purity of T cell function, the T cells generated in rapamycin also express molecules that improve immune T cell function such as CD28 and CD62L. Such rapamycin generated functional T cell subsets may have application in the prevention or treatment of GVHD after allogeneic hematopoietic stem cell transplantation, the treatment of autoimmunity, or the therapy of infection or cancer.

The present invention relates generally to methods for activating and expanding cells, and more particularly, to a novel method to activate and/or stimulate cells using an engineered multivalent signaling platform. Compositions of cells activated and expanded by the methods herein are further provided.
摘要:
The invention relates to a method for modulating HIV-1 fusion cofactor expression by manipulating CTLA-4 on the surface of T cells. The invention encompasses methods for modulating HIV-1 fusion cofactor expression by inhibiting one or more intracellular signals resulting from stimulation of CTLA-4. In one embodiment, expression of the HIV-1 fusion cofactor, CCR5, is downregulated by binding of anti-CTLA-4 antibody to CTLA-4.
