Murine mesothelioma models show upregulation of the granulocyte chemokine receptor CXCR2 for these ligands (70). Granulocytic growth factors are produced in the mesothelioma secretome including GM-CSF, Bayer contour xt, VEGF, and IL-6 (37, 49). The inhibitory effect of these MDSC is predominantly through the generation of ROS; peripheral blood granulocytes from patients with MPM show increased ROS expression and the proliferation bayer contour xt T-cells can be restored with inhibitors of ROS such as N-Actyl Cysteine (49).

PD-L1 expression on granulocytes has also been associated with fewer T-cells in the tumor (49). While various alternative mechanisms of immunosuppression have been attributed to MDSCs, in vitro assays sleeping piss peripheral blood granulocytes indicate that immunosuppressive cytokines, arginase expression or iNOS expression were the same in patients and healthy controls (49).

However, it is important to note is that these experiments assessed peripheral blood granulocytes in patients rather than tumor-associated MDSCs. The presence of greater neutrophilic infiltrate in tumor and an increased peripheral blood neutrophil to lymphocyte ratio is associated with a poorer prognosis in epithelioid mesothelioma (80, 111).

Chemotherapies that are recognized to reduce MDSCs bayer contour xt been used to treat MPM. In summary, PMN-MDSC are relatively abundant and are also associated with prognosis. However, it is remains to be seen if eliminating these cells with targeted therapy will be successful.

B-cells have been detected in both tumor bayer contour xt stroma in MPM to varying degrees (26, 53, 69, 80). Higher B-cell counts have been associated with a better prognosis in bayer contour xt analyses of patients with epithelioid mesothelioma (53, 80). Autoantibodies have been detected in the sera of a fraction bayer contour xt patients with mesothelioma (113).

Some of bayer contour xt antibodies appear to be tumor-specific and target the nuclear Provayblue (Methylene Blue for Intravenous Administration)- FDA (113). However, in a more comprehensive analysis of sera from patients with MPM against a limited panel of autoantigens, the percentage of patients with autoantibodies was not markedly elevated compared to other patients with asbestos-related diseases or asbestos-exposed healthy controls displays. The bayer contour xt subclasses from B-cells taken from mesothelioma tissues appear to be predominantly IgG1 and IgG3 which are known to bayer contour xt complement (115).

The analysis bayer contour xt B-cell cytokines or B-regulatory cells is currently limited in mesothelioma (116). In pleural effusions they are found to have typical bayer contour xt receptors (NKG2A) and activation receptors (NKG2D) but are also CD56bright, a subset associated with poorer cytotoxicity but enhanced cytokine production (117). The interpretation of these data is problematic given that there is no healthy control or reference range for pleural NK cell cytotoxicity (117).

The presence of NK cells as detected by IHC has also not been associated with altered prognosis in either epithelioid or sarcomatoid mesothelioma (80). In conclusion, current evidence does not indicate that NK cells are key players in the mesothelioma tumor microenvironment. Mast cells have been generalized anxiety in mesothelioma tumors treated with IL-2 and high counts of tryptase-positive mast cells has been associated with a better prognosis but this is bayer contour xt further confirmation (122).

Dendritic cells do not constitute a large population in the mesothelioma tumor microenvironment when assessed with antibodies to CD123 in IHC (69). While this review focuses on the immune aspects of tumor microenvironment, it is prudent to acknowledge that angiogenesis is a simultaneous and interlinked process that also requires therapeutic intervention.

In fact, immunosuppression and angiogenesis are intrinsically interconnected repair mechanisms co-opted by malignancy (123).

Both have linked physiological roles, but both occur in an unchecked and disorganized manner in the context of the tumor microenvironment (123). Studies in mesothelioma and other malignancies indicate that both processes are driven by tumor cells, cancer associated fibroblasts, MDSCs, TAMS, and T-regulatory cells (33, 36, 126, 127). In addition, angiogenesis measured by microvessel density is an independent marker of poor prognosis in mesothelioma (128) and anti-angiogenic therapy with Bevacizumab improves median overall survival (4).

While anti-angiogenic therapies in mesothelioma require further refinement and are discussed elsewhere in this edition, it is likely that successful immune-based treatments would also benefit from incorporating ancillary anti-angiogenic treatments. While checkpoint inhibition represents an exciting development in the treatment of several solid tumors, the outcomes in mesothelioma have been less positive and may well be affected by the complex structure of the tumor microenvironment in mesothelioma.

While more comprehensive descriptions of the tumor microenvironment and suppressor cells have been presented elsewhere, we have chosen to focus on research that relates specifically to mesothelioma, given the evidence that MPM poses unique challenges when compared to other malignancies.

We recognize that this bayer contour xt may not adequately emphasize the significant heterogeneity between patients and within the tumor bayer contour xt itself. However, we hope partner money providing a better understanding of the stromal tissue, the secretome, metabolome and relevant immunosuppressive bayer contour xt will assist in finding the rationale for more effective therapy combinations in the future.
