Special Issue Information

Dear Colleagues,

This is to announce a forthcoming Special Issue of the journal Antioxidants on the topic “Nrf2 in Dermatological Pathologies”. Skin diseases, such as psoriasis, skin cancers, or chronic wounds, affects millions of people worldwide, and are strong burdens to patients and health care systems. Skin as the largest body organ serve as important environmental and protection barrier against noxae. A broad spectrum of insults are dermatological toxic by catalyzing the production of reactive oxygen species (ROS) and induction of detrimental redox signaling. An overproduction of ROS can mediate cellular damage of biomolecules, opening of cell junctions, inhibition of migration, alteration of survival and apoptotic signals, and activation of pro-inflammatory responses which are mostly contra-protective for a therapeutic intervention. However, ROS also display hormesis like effects in physiological processes, cellular signal transduction, and immune responses. Essential functions are linked to the activation of the transcription factor Nrf2. Numerous studies show its crucial role in skin protection under oxidative conditions. Further exploration of detailed mechanisms of Nrf2 and down-stream signaling and its therapeutic consequences are the subject of intensive research and will be the content of the forthcoming Special Issue.

We invite both high-quality original articles, as well as reviews, from the whole research area that stimulate and contribute to a deeper understanding of Nrf2 in skin diseases, as well as of biochemical and molecular processes in living systems. Potential topics include, but are not limited to the following:

  • Dermatological diseases, cancers, chronic wounds etc.
  • Pharmacological use of Nrf2 activators
  • Structural, functional, biochemical, and molecular oxidative stress-related effects in in vitro and in vivo studies
  • Influence of reactive species on cellular and molecular responses during therapeutic processes
  • Role of stimuli showing anti-oxidant characteristics
  • Mechanisms of action of novel therapeutics
  • Prevention and management of diseases

Authors can submit their manuscripts through the Manuscript Tracking System at https://susy.mdpi.com/user/manuscripts/upload?journal=antioxidants. Manuscripts are published upon acceptance, regardless of the Special Issue publication date.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Increasing numbers of cancer deaths worldwide demand for new treatment avenues. Cold physical plasma is a partially ionized gas expelling a variety of reactive oxygen and nitrogen species, which can be harnesses therapeutically. Plasmas and plasma-treated liquids have antitumor properties in vitro and in vivo. Yet, global response signatures to plasma treatment have not yet been identified. To this end, we screened eight human cancer cell lines to investigate effects of low-dose, tumor-static plasma-treated medium (PTM) on cellular activity, immune-modulatory properties, and transcriptional levels of 22 redox-related genes. With PTM, a moderate reduction of metabolic activity and modest modulation of chemokine/cytokine pattern and markers of immunogenic cell death was observed. Strikingly, the Nuclear factor (erythroid-derived 2)-like 2 (nrf2) target heme oxygenase 1 (hmox1) was upregulated in all cell lines 4 h post PTM-treatment. nrf2 was not changed, but its baseline expression inversely and significantly correlated with hmox1 expression after exposure to PTM. Besides awarding hmox1 a central role with plasma-derived oxidants, we present a transcriptional redox map of 22 targets and chemokine/cytokine secretion map of 13 targets across eight different human tumor cell lines of four tumor entities at baseline activity that are useful for future studies in this field.

Chronic wounds and ulcers are major public health threats. Being a substantial burden for patients and health care systems alike, better understanding of wound pathophysiology and new avenues in the therapy of chronic wounds are urgently needed. Cold physical plasmas are particularly effective in promoting wound closure, irrespective of its etiology. These partially ionized gases deliver a therapeutic cocktail of reactive oxygen and nitrogen species safely at body temperature and without genotoxic side effects. This field of plasma medicine reanimates the idea of redox repair in physiological healing. This review compiles previous findings of plasma effects in wound healing. It discusses new links between plasma treatment of cells and tissues, and the perception and intracellular translation of plasma-derived reactive species via redox signaling pathways. Specifically, (i) molecular switches governing redox-mediated tissue response; (ii) the activation of the nuclear E2-related factor (Nrf2) signaling, together with antioxidative and immunomodulatory responses; and (iii) the stabilization of the scaffolding function and actin network in dermal fibroblasts are emphasized in the light of wound healing.

by Masutaka Furue, Yoko Fuyuno, Chikage Mitoma, Hiroshi Uchi and Gaku Tsuji

Abstract
Chloracne is the major skin symptom caused by dioxin intoxication. Dioxin activates the aryl hydrocarbon receptor (AHR)–cytochrome p450 1A1 (CYP1A1) system, generates oxidative stress, and induces hyperkeratinization of keratinocytes and sebocytes leading to chloracne. Nuclear factor-erythroid 2-related factor-2 (NRF2) is a master switch [...] Read more.
Chloracne is the major skin symptom caused by dioxin intoxication. Dioxin activates the aryl hydrocarbon receptor (AHR)–cytochrome p450 1A1 (CYP1A1) system, generates oxidative stress, and induces hyperkeratinization of keratinocytes and sebocytes leading to chloracne. Nuclear factor-erythroid 2-related factor-2 (NRF2) is a master switch that induces the expression of various antioxidative enzymes, such as heme oxygenase-1. Cinnamaldehyde is an antioxidant phytochemical that inhibits AHR–CYP1A1 signaling and activates the NRF2–antioxidative axis. The cinnamaldehyde-containing Kampo herbal medicine Keishibukuryogan is capable of improving chloracne in Yusho patients who are highly contaminated with dioxin. Agents with dual functions in promoting AHR–CYP1A1 inhibition and NRF2 activation may be useful for managing dioxin-related health hazards. Full article
