Cryoablation combined with programmed cell death protein 1 (PD-1) inhibitors regulates myeloid-derived suppressor cells (MDSCs) through the JAK2-STAT3-S100A8/A9 axis in mice with Lewis lung carcinoma

Cryo + PD-1 inhibitor treatment can significantly delay tumor growth in mice and inhibit the proliferation and function of MDSCs through the JAK2-STAT3-S100A8/A9 axis, thereby improving the immunosuppressive tumor microenvironment.
