Special Issue Information

Dear Colleagues,

Metabolism is a crucial process for all living organisms. A rising body of information on the roles of metabolic pathways and metabolic sensors places immunometabolism as one of the main processes that dictates immune cell differentiation, activation, and function. Metabolic pathways, such as glycolysis, glutaminolysis, and fatty acid oxidation, as well as metabolic sensors such as mTOR, HIF, and others, have been shown to be crucial in these processes. More recently, it became clear that all these processes control physiological cell function, being extremely important in an array of diseases, such as cancer and obesity, among others. Despite being a fastgrowing field, important questions remain. Consequently, to better understand how metabolism influences cell fate in immune and non-immune cells in these different settings is of paramount interest. For instance, all these pathways can generate a lot of intermediates, also called secondary metabolites, but whether these molecules have any impact directly on cells function is just starting to be explored. At the same time, blocking these metabolic pathways and sensors could be beneficial in different immune-mediated diseases.

Thus, with this Special Issue we intend to attract original papers addressing questions that uncover the role of metabolic pathways/sensors dictating immune cells function and its impact in different diseases. Special attention will be devoted to metabolic intermediates from different metabolic pathways with the ability to influence immune cells, and the use of metabolic inhibitors to treat diseases. Outstanding reviews covering these new aspects of the immunometabolism field also will be considered in this new Special Issue. We hope this Issue contributes to a better understanding of the relationship between immune cells, metabolism, and diseases.

Potential topics include but are not limited to the following:

  • Metabolic pathways on immune differentiation and function;
  • Metabolic sensors on immune function;
  • Treatment of immune diseases with metabolic inhibitors;
  • Mechanisms of immune metabolism controlling adaptive and innate cells;
  • Metabolic intermediates and their roles on immune cell function and diseases;
  • Immunity and metabolism in plants.

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. 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

For patients with end-stage renal disease requiring hemodialysis, their vascular access is both their lifeline and their Achilles heel. Despite being recommended as primary vascular access, the arteriovenous fistula (AVF) shows sub-optimal results, with about 50% of patients needing a revision during the year following creation. After the AVF is created, the venous wall must adapt to new environment. While hemodynamic changes are responsible for the adaptation of the extracellular matrix and activation of the endothelium, surgical dissection and mobilization of the vein disrupt the vasa vasorum, causing wall ischemia and oxidative stress. As a consequence, migration and proliferation of vascular cells participate in venous wall thickening by a mechanism of neointimal hyperplasia (NH). When aggressive, NH causes stenosis and AVF dysfunction. In this review we show how hypoxia, metabolism, and flow parameters are intricate mechanisms responsible for the development of NH and stenosis during AVF maturation. Full article
