Abstract excerpt
More than 60% of STAT6(-/-) mice immunologically reject spontaneous metastatic mammary carcinoma and survive indefinitely if their primary tumors are removed, whereas 95% of STAT6-competent BALB/c mice succumb to metastatic disease. BALB/c and STAT6-deficient mice with primary tumors have elevated levels of Gr1(+)CD11b(+) myeloid suppressor cells (MSCs), which inhibit T cell activation. After removal of primary...
