P2 receptors in cancer progression and metastatic spreading.
Tumor microenvironment is nucleoside and nucleotide rich. Adenosine is a key determinant of the highly immunosuppressive tumor interstitium. Extracellular ATP also affects anti-tumor immunity, albeit its effects on host-tumor interaction are incompletely understood. We give here an overview of recent literature covering the role of nucleotide-selective (P2) plasma membrane receptors in tumor growth and progression. P2 receptors are expressed on both host and cancer cells, where depending on the receptor subtype, the inflammatory infiltrate and the tumor cell type they may drive an anti-tumor response or promote tumor progression. It is anticipated that knowledge of the pharmacology, biochemistry and functional activity of the P2 receptors will allow a better understanding of host-tumor interaction and the development of innovative anti-cancer therapy.
