Abstract:
:MDSCs, which are defined as a kind of negatively regulatory cells, could suppress T cell immune response in many tumor-bearing animal models and cancer patients. We supposed that MDSCs also contributed to the impaired antitumor immunity in MDS. Here we demonstrated that STAT3-ARG1 pathway could be a critical signal transduction pathway that regulated MDSCs-mediated immunosuppression. Increased MDSCs was revealed in MDS patients when compared to healthy controls. Especially, MDSCs performed higher activated STAT3 and CCR2 expression in high-risk MDS patients. The CCL2 and IL-6 levels in MDS patients were also higher than in healthy controls, which could drive recruitment and activation of MDSCs. Meanwhile, lower expression levels of CD3ζ chain, perforin and granzyme B were demonstrated in MDS patients, which were associated with downregulated activation of CD8+ T lymphocytes. The results were supported by the decreased perforin, granzyme B and IFN-γ levels in the mixed-culture system of MDSCs and CD8+ T lymphocytes in vitro. Notably, targeting STAT3 pathway by selective inhibitor could decrease ARG1 expression in MDSCs and partially reverse the lower expression levels of effector molecules on CD8+ T lymphocytes. Therefore, this study revealed the potential STAT3-ARG1 mechanism behind MDSCs and provided a promising STAT3 targeting strategy in MDS.
