Special Issue Information
Dear Colleagues,
Mitochondria perform a multitude of essential functions within eukaryotic cells and engage in extensive communication with virtually all other cellular organelles. Their primary role is to generate cellular energy through the process of oxidative phosphorylation. This process is intrinsically linked to the production of reactive oxygen species (ROS), molecules that have a hormetic behaviour. While excessive ROS can damage cellular components, including the mitochondria themselves, at controlled levels they serve as important regulators of cellular function.
Mitochondria possess an efficient and adaptable antioxidant defence system able to not only neutralise mitochondrial-derived ROS but also contribute to the detoxification of ROS from other intracellular sources, positioning mitochondria as key regulators of cellular redox homeostasis.
Controlled ROS production plays a critical role in cell signalling, acting as secondary messengers in a range of physiological processes, including adaptation to hypoxia, autophagy regulation, immune response modulation, cellular differentiation, longevity, and metabolic adaptation to physical activity.
Under pathological or stress-related conditions, ROS production can become excessive. This disrupts mitochondrial integrity and initiates a deleterious cycle wherein oxidative damage to components of the respiratory chain, and the Krebs cycle leads to further ROS overproduction. This positive feedback loop amplifies oxidative stress, resulting in widespread cellular injury and functional decline. The progressive accumulation of oxidative damage and loss of mitochondrial integrity are central to the development of numerous non-communicable diseases. These insights underscore the urgent need for a deeper understanding of ROS-related signalling pathways and the identification of strategic molecular targets for effective therapeutic intervention.
We invite you to submit to this second edition of the Special Issue your latest research or a review article aimed at elucidating the fundamental role of mitochondria in modulating cellular ROS dynamics. In addition, the Special Issue’s scope has been broadened to encompass the identification and characterisation of natural bioactive compounds derived from plant and animal-based food matrices that exhibit the capacity of modulating mitochondrial function.

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. Antioxidants 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 2900 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.
