Abstract

Official abstract text for this publication.

The present invention relates generally to methods for stimulating T cells, and more particularly, to methods to eliminate undesired (e.g., autoreactive, alloreactive, pathogenic) subpopulations of T cells from a mixed population of T cells, thereby restoring the normal immune repertoire of said T cells. The present invention also relates to compositions of cells, including stimulated T cells having restored immune repertoire and uses thereof.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for activating and expanding naïve T cells present in a mixed population of T cells comprising naïve T cells and antigen-specific memory T cells, the method comprising: contacting the mixed population of T cells with a surface having attached thereto agents with binding activity to cell surface moieties on the surfaces of T cells in the mixed population, thereby (a) expanding naïve T cells, and (b) deleting antigen-specific memory T cells present in the mixed population of T cells, wherein the agents having binding affinity for CD3 protein complexes and CD28 proteins, and wherein the ratio of surface to cells is at least 5:1. 2. The method of claim 1 , wherein one or both of the agents are antibodies or an antibody fragments. 3. The method of claim 1 , wherein one of the agents is an anti-CD3 antibody or an anti-CD3 antibody fragment. 4. The method of claim 1 , wherein one of the agents is an anti-CD28 antibody or an anti-CD28 antibody fragment. 5. The method of claim 1 , wherein an anti-CD3 antibody or an anti-CD3 antibody fragment and an anti-CD28 antibody or an anti-CD28 antibody fragment are co-localized on the same surface. 6. The method of claim 1 , wherein the ratio of surface to cells is between 5:1 and 10:1.
