Special Issue Information
Dear Colleagues,
Innate immune cells have been shown to be able to articulate non-specific memory-like responses known as trained immunity (or innate memory; abb. TRIM), manifested with increased responsiveness against secondary pathogenic insults. Contrary to trained immunity, endotoxin tolerance is a well-known immune reaction characterized by declined responsiveness and increased repairing/anti-inflammatory reactions. Both of these opposing adaptive features of the innate immune system are shaped by different external and internal stressors, promoted mainly by epigenetic changes (including histone methylation or acetylation) with resulting changes in metabolism (glycolysis, glutaminolysis, the accumulation of fumarate, fatty acid oxidation, or itaconate pathway) and mediated particularly by the phosphoinositide 3-kinase (PI3K)/mechanistic target of the rapamycin (mTOR) pathway. Recent advances have revealed that trained memory as well as tolerance may alter several cellular functions such as migration, phagocytosis, killing abilities, and anti-microbial properties. This then has a major impact on the progression or suppression of different inflammatory diseases (i.e., allergies, atherosclerosis, asthma, obesity, sepsis, autoimmune diseases, transplant rejection, multi-system inflammatory syndrome (COVID-19)). The inappropriate induction of one of these antagonistic adaptive manners may result in maladaptive reactions which trigger life-threating events. As such, we invite all the colleagues to submit their findings in this Special Issue to further provide more insights on the role of the trained immunity and tolerance development in inflammatory disorders.

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. Biomedicines is an international peer-reviewed open access monthly 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 2600 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.
