Simple Summary: Pancreatic cancer is one of the most lethal forms of malignancies; therefore, new treatment strategies are required to increase the patients' survival. It has been established that different cell types that surround pancreatic cancer cells, thus forming the tumor microenvironment, are responsible for tumorigenicity and inefficacy of treatments, including immunotherapy. In the present review, we aim to summarize current knowledge regarding the molecular mechanisms underpinning the interaction of cancer cells with cells of their microenvironment and discuss associated strategies to improve treatment results. Pancreatic cancer demonstrates an ever-increasing incidence over the last years and represents one of the top causes of cancer-associated mortality. Cells of the tumor microenvironment (TME) interact with cancer cells in pancreatic ductal adenocarcinoma (PDAC) tumors to preserve cancer cells' metabolism, inhibit drug delivery, enhance immune suppression mechanisms and finally develop resistance to chemotherapy and immunotherapy. New strategies target TME genetic alterations and specific pathways in cell populations of the TME. Complex molecular interactions develop between PDAC cells and TME cell populations including cancer-associated fibroblasts, myeloid-derived suppressor cells, pancreatic stellate cells, tumor-associated macrophages, tumor-associated neutrophils, and regulatory T cells. In the present review, we aim to fully explore the molecular landscape of the pancreatic cancer TME cell populations and discuss current TME targeting strategies to provide thoughts for further research and preclinical testing.
