| Sumario: | Cancer comprises a group of entities characterized by uncontrolled growth of abnormal cells, which have different morphology, clinical manifestations and prognosis. The tumor microenvironment (TME) is the cell environment in which the tumor develops. In addition to tumor cells, TME includes surrounding blood vessels, extracellular matrix (ECM), stromal cells, tumor-associated fibroblasts, cells of the immune system and also signaling molecules. By using specific markers, different cell types that make up the TME can be identified. Within the cells of the immune system, T lymphocytes, B lymphocytes, natural killer cells (NK), macrophages and dendritic cells (DC) among others can be identified. Different DC subpopulations have been identified, including myeloid or conventional DC`s that initiate T cell immunity and antibody production, and plasma DC cells that play an important role in antiviral immunity and immune tolerance. The mutual interaction between the tumor cells and the infiltrates play a decisive role in the progression and metastasis of the tumor. It is important to understand the tumor microenvironment and to characterize the location and state of immune cells and their interaction with tumor cells. In line with this idea, a deeper understanding of the different populations of dendritic cells present in tumors is crucial, which will make it possible to propose new therapeutic alternatives within the framework of cancer immunotherapy and also to develop biomarkers to apply in the management of cancer patients . We believe that the DCs found in the TME have a fundamental role in the development of the mammary tumor, that is why we ask ourselves: What is the profile of maturation / activation of the dendritic cells present in the tumor microenvironment of human mammary carcinomas? |
