Myeloid-derived suppressor cell accumulation and function in patients with newly diagnosed glioblastoma

Estrogens drive myeloid-derived suppressor cell accumulation

Regulatory T Cells and Myeloid-Derived Suppressor Cells in Patients with Peptic Ulcer and Gastric Cancer

Background: Regulatory T Cells (Tregs) and Myeloid-Derived Suppressor Cells (MDSCs) are two main regulatory cells modulating the immune responses in inflammation and cancer. Objective: To investigate and compare Tregs and MDSCs in peptic ulcer and gastric cancer. Methods: Patients with dyspepsia were selected and divided into three groups of non-ulcer dyspepsia (NUD, n=22), peptic ulcer disease...

Myeloid-derived Suppressor Cells in Glioblastoma Patients - Phenotype, Function and Clinical Relevance

TNF signaling drives myeloid-derived suppressor cell accumulation.

TNF, an inflammatory cytokine that is enriched in the tumor microenvironment, promotes tumor growth and subverts innate immune responses to cancer cells. We previously reported that tumors implanted in TNF receptor-deficient (Tnfr-/-) mice are spontaneously rejected; however, the molecular mechanisms underlying this rejection are unclear. Here we report that TNF signaling drives the peripheral ...

Sunitinib mediates reversal of myeloid-derived suppressor cell accumulation in renal cell carcinoma patients.

PURPOSE Immune dysfunction reported in renal cell carcinoma (RCC) patients may contribute to tumor progression. Myeloid-derived suppressor cells (MDSC) represent one mechanism by which tumors induce T-cell suppression. Several factors pivotal to the accumulation of MDSC are targeted by the tyrosine kinase inhibitor, sunitinib. The effect of sunitinib on MDSC-mediated immunosuppression in RCC pa...
