| 摘要 |
Described herein are novel compositions comprising MT1 and/or MT2 modulators (i.e., inhibitors or activators), and methods using these agents for targeting different T-cell populations, for example, type 1 regulatory (Tr1) CD4+ cells and exhausted CD8+ T-cells cells. Aspects of the invention relate to inhibitors of MT1 and/or MT2 to increase the differentiation of CD4+ cell Trl1 CD4+ cells and increase in the activity of Tr1 cells, e.g., to increase IL-10 production. In alternative embodiments, MT1 and/MT1 inhibitors can be used to increase proliferation and/or activity of exhausted CD8+ T-cells and to decrease CD8+ T-cell exhaustion (e.g., decrease functionally exhausted or unresponsive CD8+ immune cells). Accordingly, aspects of the present invention relate to compositions and methods comprising inhibitors of MT1 and/or MT2 useful in the treatment of chronic immune conditions, such as persistent infections, cancer, and autoimmune disease. |
