Modulating non-canonical autophagy (LAP) in myeloid cells to suppress tumors (SJ-17-0019)

St. Jude Reference #SJ-17-0019


Researchers at St. Jude have discovered a tumor suppressive effect by modulating non-canonical autophagy (LAP) in myeloid cells that may be useful in the development of new strategies for cancer immunotherapy by targeting components of LAP.

Targeting components of the LAP pathway for specific drug design can be used as an immunotherapy strategy that modulates the tumor microenvironment. It is well established in the literature that infiltrating monocytes and macrophages play a pivotal role in shaping the immunosuppressive tumor microenvironment. The researchers at St. Jude envision that, by modulating LAP in the innate immune cells, it will be possible to shape the function of effector T cell toward an effective, cytotoxic immune response that can eliminate human tumor cells.
