Special Issue "PD-L1, A Master Regulator of Immunity 2.0"
Deadline for manuscript submissions: 30 September 2021.
Programmed cell death ligand (PD-L1) is a co-inhibitory molecule that is expressed on immune cells and cancer cells. Through binding with its receptor, programmed death 1 (PD-1) on the T cell surface, regulates their activity. In that way, adaptive immune responses mediated by T cells against invading pathogens are strictly regulated, thereby avoiding collateral damage to the host. However, this regulatory circuit is dysregulated in several diseases as chronic infection, transplantation immunity, autoimmunity, and cancer to dampen immune responses prematurely. Blocking the PD-1:PD-L1 immune checkpoint axis has, therefore, garnered substantial interest especially in oncology. In cancer, PD-1:PD-L1 blockade has resulted in unprecedented successes in individual patients across a variety of cancer types. However, a large number of patients fail to respond to PD-1:PD-L1 blockade. Insights into different mechanisms underlying this therapy failure are gradually being gained. These insights highlight the complexity of the immune system regulatory interaction with cancer cells. Numerous studies have begun to shed light on how combination with other therapies could enhance the response rates to PD-1:PD-L1 blockade.

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 papers will be 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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.
