Oral infection with Toxoplasma gondii leads to transient systemic hyporesponsiveness. In this report, we characterized the presence in the lungs of GR1(+) CD11b(+) myeloid cells that have potent nitric oxide-dependent immunoregulatory properties. We also demonstrated the interleukin 2-reversible anergy of both pulmonary CD8(+) and CD4(+) activated T lymphocytes with infection.

The heterogeneous form of malignancy in the myeloid lineage of normal hematopoietic stem cells (HSCs) is characterized as acute myeloid leukemia (AML). The t(9;11) reciprocal translocation (p22;q23) generates MLL-AF9 oncogene, which results in myeloid-based monoblastic AML with frequent relapse and poor survival. MLL-AF9 binds with the C-Myb promoter and regulates AML onset, maintenance, and survival.

Background: Ablation is one of the main methods for local treatment of hepatocellular carcinoma (HCC). Different from radiofrequency ablation (RFA), microwave ablation (MWA) is not limited by tissue conductivity, and can use multiple electrodes at the same time to improve ablation efficiency. In addition, MWA can form a larger ablation area, which makes it possible to completely ablate large HCC.

Background: Myeloid Derived Suppressor Cells (MDSCs) are capable of inhibiting both innate and adaptive immune responses and accumulate in the microenvironment of breast tumors. Hence, MDSC depletion by chemotherapeutic agents can improve clinical efficacy of cancer immunotherapy. The effects of 5-FU and doxorubicin agents on MDSC reduction in 4T1 breast cancer murine model were evaluated.

To date, there is no licensed vaccine against the protozoan parasite (, the etiological agent of Chagas Disease. has evolved numerous mechanisms to evade and manipulate the host immune system. Among the subversive strategies employed by the parasite, marked increases in CD11b+ Gr-1+ myeloid-derived suppressor cells (MDSCs) in several organs have been described.
