Theme 3: Inflammation and the tumor immune microenvironment
Overview: Since chronic inflammation is associated with the formation of several types of cancer, several CCIR members study the physiological versus pathological roles of NF-kB signaling pathways, Th17 cells and the IL-17 family of pro-inflammatory cytokines (IL-17A – IL-17F) in preventing/forming cancer and autoimmune disease. Several CCIR members are investigating how the local tumor stroma influences mast cell function in terms of promoting or suppressing tumor cell growth and survival based on previous observations that an influx of mast cells in tumors can be either a good or poor prognostic indicator, depending on the type of cancer. And finally, CCIR members are investigating mechanisms by which tumor cells induce T cell tolerance or responses. Results of these studies will be translated to find ways enabling immunotherapy to induce, restore or boost anti-tumor immunity in cancer patients.
