Abstract

The invention provides an isolated, purified population of human cells comprising CD8+ T cells with reduced Cbl-b activity. The invention provides uses of such cells in methods for inducing or enhancing an anti-tumor immune response in a subject. These methods comprise: (a) providing a cell population, from a subject or from another source, which comprises CD8+ T cells, (b) reducing Cbl-b activity in the CD8+ T-cells, (c) administering the cells of step (b) to the subject. The invention provides methods for making CD8+ T cells that do not require stimulation through a co-receptor in order for the cell to become activated or proliferated in response to contact via its T cell receptor. Such methods are based upon reducing function of Cbl-b. The invention also provides methods for identifying agents which affect Cbl-b expression or activity.
