The present invention provides an agent comprising a cyclic peptide comprising a T cell antigen peptide, wherein the T cell antigen peptide cannot elicit a T cell response in a cyclized form, and one or more of said cyclic peptides By selectively cleaving these cleavage sites, the T cell antigen peptide can elicit a T cell response. The agent can be used to prevent or treat conditions characterized by the presence of unwanted cells. [Selection] Figure 7 |
