Novel Signaling Mechanisms of G Protein-Coupled Receptors

Dear Colleagues,

Members of the G protein-coupled receptor (GPCR) superfamily represent the largest group of cell membrane receptors, responsible for transducing a vast array of signals that lead to diverse cellular responses. Their dysfunction is implicated in numerous diseases, including cancer, making GPCRs one of the primary targets for the current marketed drugs. GPCRs are also one of the most studied proteins in molecular pharmacology.

GPCRs exhibit multiple conformations and signaling possibilities. Biased ligands can induce selective signaling of the receptors, adding another layer of complexity to GPCR functions. Activated GPCRs are able to initiate waves of signaling events through various mechanisms, including activation of G proteins, binding to β-arrestins and transactivation of other receptors, and even some internalized receptors can induce signaling.

The aim of this Special Issue is to provide an overview of the latest findings in the novel aspects of GPCR functions and signaling. Therefore, this Special Issue of Cells invites contributions of review articles and original research papers that cover the novel, exciting aspects of GPCRs, providing a better understanding of the complexity of their functions.

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 250 words) can be sent to the Editorial Office for assessment.

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.
