Abstract
The field of the invention is generally related to methods used for the induction of T cells with suppressive activity. More specifically, the methods are used to generate professional regulatory T cells and cytokine-producing T cells with enhanced suppressive activity.
Claims15
A method for generating regulatory T cells comprising:
- treating a population of CD4+ T cells comprising conventional T cells and professional regulatory T cells with a regulatory composition comprising (i) at least one cytokine;
- (ii) at least one T cell activator;
- and (iii) at least one population of non T accessory cells for a period of time sufficient to increase the number of said professional regulatory T cells with suppressive activity in said population of CD4+ T cells.
A method for generating regulatory T cells comprising:
- a) treating conventional T cells with a regulatory composition comprising (i) at least one cytokine;
- (ii) at least one T cell activator;
- and (iii) at least one population of non T accessory T cells for a period of time sufficient generate a population of cytokine producing regulatory T cells.
A method for inducing the expression of CD122 on the surface of regulatory T cells comprising:
- treating a population of CD4+ T cells comprising conventional T cells and professional regulatory T cells with a regulatory composition comprising (i) at least one cytokine;
- (ii) at least one T cell activator;
- and (iii) at least one population of non T accessory cells for a period of time sufficient to generate regulatory T cells that express the CD122 marker on their surface.
A method for generating regulatory T cells comprising:
- a) making a CD4+ T cell population comprising activated professional regulatory T cells and a conventional T cells;
- and,
- b) adding at least one T cell activator to said CD4+ T cell population for a period of time sufficient to generate a regulatory cell population comprising professional regulatory T cells and cytokine producing regulatory T cells.
