Project description:Cancer types with lower mutational load and a non-permissive tumor microenvironment are intrinsically resistant to immune checkpoint blockade. While the combination of cytostatic drugs and immunostimulatory antibodies constitutes an attractive concept for overcoming this refractoriness, suppression of immune cell function by cytostatic drugs may limit therapeutic efficacy. Here we show that targeted inhibition of mitogen-activated protein kinase (MAPK) kinase (MEK) does not impair dendritic cell-mediated T-cell priming and activation. Accordingly, combining MEK inhibitors (MEKi) with agonist antibodies (Abs) targeting the immunostimulatory CD40 receptor resulted in potent synergistic anti-tumor efficacy. Detailed analysis of the mechanism of action of MEKi GDC-0623 by means of flow cytometric analysis of the tumor immune infiltrate and whole tumor transcriptomics showed that, in addition to its cytostatic impact on tumor cells, this drug exerts multiple pro-immunogenic effects, including the suppression of M2-type macrophages, myeloid derived suppressor cells and CD4+ T-regulatory cells. In addition, MEKi was found to induce tumor-cell intrinsic interferon signaling, which contributed to antigen presentation by tumor cells. Finally, the tumoridical impact of MEKi involves the activation of multiple pro-inflammatory pathways involved in immune cell effector function in the tumor microenvironment. Our data therefore indicate that the combination of MEK inhibition with agonist anti-CD40 Ab is a promising therapeutic concept, especially for the treatment of mutant Kras-driven tumors such as pancreatic ductal adenocarcinoma. We used microarrays to monitor transcriptional and cell-type composition changes in murine transplantable tumor models of pancreatic ductal adenocarcinoma (PDA30364), colon cancer (MC38) and melanoma (B16-OVA) upon treatment with MEK inhibitor (GDC-0623), anti-CD40 antibody or the combination of GDC-0623 and anti-CD40 antibody.

Project description:The interaction between the transmembrane glycoprotein surface receptor CD40 expressed by skin keratinocytes (KCs) and its T cell-expressed ligand CD154 was suggested to exacerbate inflammatory skin diseases. However, the full spectrum of CD40-mediated effects by KCs underlying this observation is unknown. Therefore, changes in gene expression after CD40 ligation of KCs were studied by microarrays. CD40-mediated activation for 2 hours stimulated the expression of a coordinated network of immune-involved genes strongly interconnected by IL8 and TNF, while after 24 hours anti-proliferative and anti-apoptotic genes were upregulated. CD40 ligation stimulated the production of chemokines that attracted lymphocytes and myeloid cells from peripheral blood mononuclear cells (PBMCs). Thus, CD40-mediated activation of KCs resulted in a highly coordinated response of genes required for the local development and sustainment of adaptive immune responses. The importance of this process was confirmed by a study on the effects of human papilloma virus (HPV) infection to the KCâs response to CD40 ligation. HPV infection clearly attenuated the magnitude of the response to CD40 ligation and consequently the KCâs capacity to attract PBMCs. The fact that HPV attenuates CD40 signalling in KCs indicates the importance of the CD40-CD154 immune pathway in boosting cellular immunity within epithelia. Total RNA from eight 72 hours 50 IU/ml IFNgamma pre-stimulated primary undifferentiated keratinocyte cultures, four uninfected and four HPV-positive, that were either left unstimulated, or stimulated for 2 hours with IFNgamma and Control- or CD40L-expressing L-cells (mouse fibroblasts), or stimulated for 24 hours with IFNgamma and Control- or CD40L-expressing L-cells. The stimulated samples were generated in duplo. 72 samples were generated in total.
