Furthermore, inhibition of GSDMD reduced the number of myeloid derived suppressor cells (MDSC) in the metastatic lung of breast cancer mouse model, while concurrently increasing both the percentage and total cell count of CD8<sup>+</sup> T cells, suggesting that mitochondrial dysfunction-dependent GSDMD activation promotes tumor microenvironment immunosuppression and NETs. The gene discussed is CD8A; the disease is breast cancer.
