Special Issue Information
Dear Colleagues,
The cellular microenvironment governs tissue development and homeostasis through multiple regulatory mechanisms, including soluble ligand–receptor interactions, extracellular vesicle release, and cell–cell- and cell–matrix-mediated intercellular communication. In addition, the physicochemical properties of the microenvironment, such as the local stiffness, viscosity, osmolarity and diffusion properties, can critically affect cellular physiology.
The cellular microenvironment changes during aging and disease. During the progression of joint diseases, such as osteoarthritis, inflammation drives the active remodeling of the extracellular matrix (ECM). ECM alterations, in turn, change the biomechanical environment of cells, which leads to metabolic changes and further drives the pathologic cascades. In cancer, ECM remodeling promotes immune escape, tumor survival and metastasis. In the brain, alterations in ECM composition and integrity contribute to the pathophysiology of epilepsy, dementia and psychiatric disorders. In neurological conditions such as stroke, multiple sclerosis and neurodegenerative diseases, EVs and the ECM regulate neuroplasticity.
In this Special Issue, we aim to explore how the cellular microenvironment can be targeted to prevent or modify the time course of diseases in different organs, including the brain, cartilage, skin, liver, lung, kidney and cardiovascular system. Particularly, but not exclusively, we expect to collect reviews, as well as experimental and bioinformatic studies focusing on the following:
- New mechanisms of extracellular signaling, particularly “vicious cycles” linking impaired proteostasis, aggregation of peptides/proteins, extracellular vesicle release and inflammation with ECM and tissue remodeling;
- Cellular dysfunctions during acute and chronic phases of tissue repair triggered by the dysregulation of extracellular proteases and their tissue inhibitors;
- Role of extracellular vesicles in pathophysiological and recovery mechanisms;
- Novel antifibrotic strategies;
- Drugs targeting biosynthesis, glycosylation, proteolysis and other posttranslational modifications of ECM molecules and their receptors, and related biomarkers;
- Emerging gene therapies targeting the regulation of ECM abundance and composition.

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.
