Special Issue Information

Dear Colleagues,

Inflammatory bowel disease (IBD), including Crohn disease (CD) and ulcerative colitis (UC), is a multifactorial disorder characterized by chronic inflammation and altered gut barrier function. IBD etiopathogenesis is still debated, with several possible triggers converging to similar pathological effects. During the last few decades, numerous discoveries have contributed to elucidating the role of the mucosal immune response, the importance of the gut barrier and the mucus layer integrity and the role of the intestinal microbiota. Despite this progress and the increasing number of pharmacological options, IBD patients still suffer from frequent disease relapse and an important percentage of patients do not respond to treatment, including biological drugs. Increased reactive oxygen species generation (oxidative stress) is a condition associated with IBD pathogenesis and disease relapse. Adjuvant therapies targeting oxidative stress remain limited, despite the numerous reports suggesting their potential beneficial effects in preclinical and clinical research.

The purpose of this Special Issue is to review the current state of the art regarding antioxidant development and clinical/pre-clinical translation in the context of inflammatory bowel disease onset, treatment and remission maintenance. Prevention of IBD-related complication, particularly colon rectal cancer, will also be taken into deep consideration.

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.

The pathogenesis of Inflammatory Bowel Disease (IBD) involves complex mechanisms, including immune dysregulation, gut microbiota imbalances, oxidative stress, and defects in the gastrointestinal mucosal barrier. Current treatments for IBD often have significant limitations and adverse side effects, prompting a search for alternative therapeutic strategies. Natural products with anti-inflammatory and antioxidant properties have demonstrated potential for IBD management. There is increasing interest in exploring food industry waste as a source of bioactive molecules with healthcare applications. In this study, a co-culture system of Caco-2 cells and PMA-differentiated THP-1 macrophages was used to simulate the human intestinal microenvironment. Inflammation was induced using TNF-α and IFN-γ, followed by treatment with Saffron Petal Extract (SPE). The results demonstrated that SPE significantly attenuated oxidative stress and inflammation by downregulating the expression of pro-inflammatory mediators such as iNOS, COX-2, IL-1β, and IL-6 via modulation of the NF-κB pathway. Given that NF-κB is a key regulator of macrophage-driven inflammation, our findings support further investigation of SPE as a potential complementary therapeutic agent for IBD treatment. Full article
