members of the same family, but involve receptors as diverse as receptor kinases, prostanoid receptors, purinergic We will discuss recent evidence as well as what we consider as emerging areas to explore; from the signalling relevance of these interactions, since this additional level of molecular cross-talk between receptors and signaling

Regulator G protein Signaling (RGS) proteins are critical components of the intracellular signaling pathways and amplitude of GPCR signaling. Another signaling pathway related to RGS4 involves the regulation of the immune response.

It plays a critical role in transmitting signals inside the body, which is necessary for controlling Its significance extends from intracellular signaling pathways to tumor regression. Purinergic signaling, a form of extracellular paracrine signaling, relies on purine nucleotides. This review explores e-ATP metabolism, its purinergic signaling, and therapeutic strategies targeting receptors , Purinergic signaling , Therapeutic potential , Tumor microenvironment (TME) Source Contribute

interdisciplinary approaches (synthesis, modeling, pharmacology) to study G protein-coupled receptors (GPCRs) and purinergic signaling and now has four compounds in clinical trials.
