Anti-Cachexia Effect Of Polymorphonuclear Myeloid-Derived Suppressor Cell Depletion Therapy Is Not Present In Tumor-Bearing Mice Lacking T And B Cells, Hailey K. Gorman, Jonathan Specht, Michael Deyhle

International Journal of Exercise Science: Conference Proceedings

Polymorphonuclear (PMN) Myeloid-derived suppressor cells (MDSCs), are associated with poor cancer prognosis, partly due to their immunosuppressive effects on anti-cancer immunity. Cancer cachexia, characterized by debilitating skeletal muscle wasting, further reduces patient survival. Previously, antibody-mediated (anti-Ly6G) depletion of PMN-MDSCs attenuated skeletal muscle loss in mouse model of cancer cachexia. The mechanism by which PMN-MDSCs contribute to cachexia is unclear. Given the role that PMN-MDSCs play in supporting cancer disease progression depends on inhibiting anti-cancer adaptive immunity, we tested if the beneficial effects of PMN-MDSCs depletion on cachexia depend on the presence of adaptive immune cells. PURPOSE: We hypothesize that the …
