So, your presentation will perfectly reach your audience. It doesn't have too busy graphics and distracting colors. It has twelve textboxes placed neatly in the fishbone to make your presentation easy to follow. ![]() ![]() These cells were named MDSCs in 2007 to reflect their origin and major functional trait, i.e., the ability to suppress T cell activation and function. The Best Ishikawa Template PPT Slide includes a simple fishbone diagram with twelve nodes. MDSCs were studied initially in the context of cancer. In recent years, it has become clear that these cells also play an important role in the regulation of immune responses in chronic infections, inflammation, autoimmune diseases, and other pathologic conditions. MSDC frequency has also been reported to increase with aging. MDSCs are phenotypically distinct from terminally differentiated DCs and MΦ and represent a heterogeneous population of immature myeloid cells that include cells with granulocytic and monocytic morphology and phenotype. MDSCs are known for their ability to suppress immune responses and to promote tumor growth by supporting angiogenesis, tumor cell survival, metastases, and formation of premetastatic niches. MDSCs are now divided into 2 major populations: granulocytic or PMN-MDSC and mononuclear or M-MDSC.Įxtensive studies in recent years have provided ample evidence of the clinical relevance of MDSCs. In most types of cancer, PMN-MDSCs represent 70–80% of the total MDSC population, whereas M-MDSCs usually represent no more than 20%. In some chronic infections, M-MDSCs are predominant population of MDSCs. In mice, PMN-MDSCs are commonly defined as CD11b +Ly6G +Ly6C lo cells and M-MDSCs as CD11b +Ly6G −Ly6C hi. In humans, MDSCs are purified from the mononuclear fraction after Ficoll gradient cenrifugation. PMN-MDSCs are defined as CD11b +CD33 +CD14 −CD15 + cells and M-MDSC as CD14 +HLA-DR −/lo or as CD11b +CD33 +CD15 −CD14 −. Another commonly used combination of markers includes lineage (CD3, CD14, CD19, CD56) −HLA-DR −CD33 +. These cells represent a mixed population of PMN-MDSCs and M-MDSCs, as well as early myeloid progenitors.
