Special Issue Information
Dear Colleagues,
The purinergic signaling system comprises both adenosine receptors (ARs) and purinergic receptors (P2Rs), where adenosine and nucleotides act as extracellular messengers, respectively.
In particular, adenosine exerts its function through the activation of four AR subtypes, A1, A2A, A2B, and A3, which are G protein-coupled receptors, while P2Rs comprise both ionotropic receptors (P2X1-7R) and metabotropic receptors (P2Y1,2,4,6,11-14R). The signaling pathways activated by ligand–receptor interaction are cross-linked with other transmitter networks to regulate numerous key physiological processes like proliferation, differentiation, and apoptosis. Thus, the deregulation of the system establishes pathological conditions that include, but are not limited to, inflammation, cancer, and neurodegeneration. Few adenosinergic and purinergic drugs have been approved to date. Great efforts are still focused on the research and development of ligands, with emerging interest in the field of allosteric modulation, biased agonism, and bitopic ligands. On the other hand, even more efforts are ongoing in understanding the pathophysiological implications of the different receptors in order to validate them as targets in specific diseases.
With this Special Issue, we aim to shed light on the pharmacology of AR and P2R, as well as present the advancements in the development of ligands towards them. We look forward to receiving your contributions.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cells is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
