a) contacting a population of CD4+ T cells with:\n\n(1) an agent which provides a primary activation signal to the CD4+ T cells thereby activating the CD4+ T cells, wherein the agent is selected from the group consisting of an anti-CD3 antibody or a CD3-binding fragment thereof, an anti-CD2 antibody or a CD2-binding fragment thereof, and an antigen in a form suitable to trigger a primary activation signal in the CD4+T cell when complexed with the TCR/CD3 complex; and\n(2) an anti-CD28 antibody or a CD28-binding fragment thereof, thereby stimulating the activated CD4+ T cells, such that the CD4+ T cells are stimulated to proliferate and produce at least one TH1 cytokine selected from the group consisting of IL-2 and IFN-γ,\n
the agent which provides a primary activation signal and the anti-CD28 antibody or CD28-binding fragment thereof being attached to the same surface,\n
wherein an increase in the amount of the at least one TH1 cytokine following activation and stimulation of the CD4+ T cells compared to the amount of the at least one TH1 cytokine produced by CD4+ T cells that have not been activated as in (1) and stimulated in (2), indicates selective expansion of the TH1 cells."],"number":1,"annotation":false,"title":false,"claim":true},{"lines":["The method of claim 1, further comprising:\n
