TUMOR SUPPRESSION BY MODULATION OF NON-CANONICAL AUTOPHAGY (LAP) IN MYELOID CELLS

摘要

Compositions and methods are provided for suppressing tumors by modulating the LAP pathway. Targeting components of the LAP pathway for specific drug design can be used as n immunotherapy strategy that modulates the tumor microenvironment. It is well established that infiltrating monocytes and macrophages play a pivotal role in shaping an immunosuppressive tumor microenvironment. By modulating LAP in the innate immune cells, the function of effector T cells can be manipulated toward an effective, cytotoxic immune response that can eliminate tumor cells. Thus, methods are provided for reducing the size or number of tumor cells and for treating cancer or other cell proliferative disorders. Further provided are methods for increasing the Th1 response or increasing IFNγ and/or TNFα expression in the tumor microenvironment by administering a LAP inhibitor.
