Ectonucleotidases in Tumor Cells and Tumor‐Associated Immune Cells: An Overview

BioMed Research International, Volume 2012, Issue 1, 2012., 2012
Increasing evidence points out that genetic alteration does not guarantee the development of a tumor and indicates that complex interactions of tumor cells with the microenvironment are fundamental to tumorigenesis. Among the pathological alterations that give tumor cells invasive potential, disruption of inflammatory response and the purinergic ...
