Ze-Qi-Tang Formula Induces Granulocytic Myeloid-Derived Suppressor Cell Apoptosis via STAT3/S100A9/Bcl-2/Caspase-3 Signaling to Prolong the Survival of Mice with Orthotopic Lung Cancer

The immune regulatory activity of TCM formula ZQT in TME. ZQT induces the apoptosis of G-MDSCs via the STAT3/S100A9/Bcl-2/caspase-3 signaling pathway, resulting in a significant decrease in G-MDSCs and their immunosuppressive activity, consequently promoting the infiltration and killing activity of CD8⁺ T cells, leading to the inhibition of the proliferation of tumor cells.
