Special Issue Information
Dear Colleagues,
The environmental impact of micro- and nanoplastics (MNPs) has dramatically increased, representing a major global concern in virtue of their persistence and bodily accumulation. Recently, dietary nutrients have gained considerable attention for enhancing resilience to MNPs and overall human health. Dietary nutrients including food extracts, polyphenols, and more bioavailable polyphenol-combined nanoparticles, as well as vitamin C, vitamin E, vitamin D, and omega-3 fatty acids, have been shown to improve the permeability of the blood–brain barrier (BBB), intestinal epithelial barrier (IEB), and blood retinal barrier (BRB) and ultimately brain function, thus inhibiting apoptosis, inflammation, intestinal, and neuronal toxicity due to the presence of MNPs in various organs. Interestingly, dietary nutrients display biphasic dose–response effects by activating, at the minimum dose, anti-apoptotic pathways such as Bcl-2, tight junction proteins (e.g., claudins, occludins, and ZO‐1), the Nrf2 pathway, and antioxidant proteins (e.g., heme oxygenase-1 upregulated by curcumin and sirtuin-1 activated by resveratrol) to block reactive oxygen species (ROS) and restore barrier integrity. The impairment of tight junctions due to environmental pollutants and deregulation of Nrf2 signaling may exacerbate selective susceptibility under neuroinflammatory conditions to the onset and progression of metabolic and brain disorders such as diabetes, anxiety, depression, and autism as well as neurodegeneration due to the vulnerability of sensory neurons to apoptosis and oxidative stress. The Special Issue focuses on nutrition targeting several cellular and molecular pathways to block MNP-induced toxicity and regulate impaired tight junctions and epigenetic alterations and explores the underlying mechanisms using innovative in vitro and in vivo technologies for the development of promising protective strategies and personalized nutritional therapies in order to prevent or attenuate oxidative stress, apoptosis, and inflammation and, consequently, promote human health.

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. Toxics 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.
