Special Issue Information

Dear Colleagues,

Lipid peroxidation is a fundamental biological process that has both physiological and pathological implications. Under controlled conditions, lipid peroxidation products act as signaling molecules involved in cellular homeostasis, immune responses, and redox regulation. However, excessive oxidative stress disrupts this balance, leading to the accumulation of reactive lipid species that drive chronic inflammation, thus causing tissue damage. The imbalance between oxidative insult and antioxidant defenses plays a crucial role in the pathogenesis of various conditions, including cardiovascular diseases, neurodegenerative disorders, cutaneous diseases, metabolic syndrome, and autoimmune diseases.

This Special Issue aims to explore both the beneficial and detrimental aspects of lipid peroxidation, particularly its contribution to chronic inflammatory diseases. 

We welcome original research articles, reviews, and clinical studies that investigate the following:

  • The physiological roles of lipid peroxidation-derived molecules in cellular signaling and homeostasis.
  • The molecular mechanisms linking excessive lipid peroxidation to chronic inflammation.
  • Biomarkers of lipid peroxidation as potential diagnostic or prognostic tools.
  • The role of antioxidant defense systems in maintaining lipid peroxidation homeostasis.
  • Therapeutic strategies targeting lipid peroxidation to mitigate inflammation and disease progression.
  • The crosstalk between lipid peroxidation, immune responses, and metabolic dysfunction.

By gathering cutting-edge research from various disciplines—including biochemistry, molecular biology, pharmacology, and clinical sciences—this Special Issue will provide a comprehensive understanding of lipid peroxidation's dual role in physiology and pathology, with implications for the development of novel therapeutic strategies.

Lipid peroxidation (LPO) is a biochemical process through which lipids are subjected to a peroxidation reaction in the presence of free radicals. The process can cause alterations in biological membranes and the formation of substances harmful to the body that can form aggregates with proteins and nucleic acids. Malondialdehyde (MDA) and 4-hydroxynonenal (4-HNE) are the main products of LPO. These compounds have cytotoxic and genotoxic properties and contribute to the pathogenesis of various diseases. This research focuses on the correlation between LPO and skin diseases. For some skin diseases, such as psoriasis, vitiligo, and alopecia, LPO products have been shown to have a clear role in the pathogenesis of the disease. Lipid aldehydic products like MDA and 4-HNE can enhance inflammation by stimulating pro-inflammatory genes and producing cytokines. Furthermore, these products can stimulate cell death and increase oxidative stress. For other diseases (atopic dermatitis, urticaria, pemphigus, and melanoma), the role of LPO is unclear, even if the levels of LPO biomarkers are elevated in proportion to the severity of the disease. LPO can also be exploited to counteract the proliferation of neoplastic cells. Therefore, enhancing LPO would play an adjuvant role in the therapy of neoplastic diseases such as melanoma. In particular, the therapeutic implication resulting from the role of LPO products in the cytotoxicity induced by photodynamic therapy used for the adjuvant treatment of melanoma could be of interest in the future.
