Special Issue Information

Dear Colleagues,

There are enormous discoveries in lipid biology, thanks to the development of lipidomics and "the large-scale study of pathways of cellular lipids in biological systems”. This has clarified the regulatory mechanisms of lipids and facilitated research on lipid-metabolizing enzymes, as well as the role of lipids in energy metabolism and metabolic homeostasis. Besides their role in energy production and storage, fats also influence processes such as cardiovascular disease, thermogenesis, insulin sensitivity, glucose homeostasis, inflammation, and redox status. Authors are invited to submit their original research within and beyond this frame.

  • Nuclear or membrane-bound receptors have been identified as omega-3 and omega-6 (polyunsaturated fatty acids) PUFA-specific receptors. However, this field remains underexplored. Omega-3 deals with key metabolic processes like immunomodulation, regulation of inflammation, cardiovascular diseases, insulin sensitivity, and lipid metabolism. Omega-3 has enormous positive functions in the organism. The potential therapeutic use of these fatty acids in disease treatment is an active area of research. Overall, this is an immensely intriguing field, marked by uncertainties.
  • Omega-6 PUFAs are significant because there is no scientific consensus regarding their beneficial or harmful effects on human health. Examples include omega-6, gamma-linolenic acid (GLA), which may play a role in resolving certain inflammatory processes, while some authors consider linoleic acid as a proinflammatory FA.
  • Oxylipins are bioactive lipid mediators derived from PUFA via enzymatic or non-enzymatic pathways in all aerobic organisms. This broad group of molecules encompasses well-known families, including prostaglandins, prostacyclins, thromboxanes, leukotrienes, lipoxins, as well as specialized pro-resolving mediators such as resolvins, protectins, and maresins, along with isoprostanes and several smaller subclasses. Their effects—pro or anti-inflammatory—depend on the PUFA source and production pathway. Oxylipins regulate inflammation and homeostasis, but many of their specific roles, especially within certain subclasses, remain unclear, underscoring the need for further study.
  • Lipid peroxidation is linked to cancer development, representing another important aspect to reconsider. A new marker for cancer biogenesis could be endogenously synthesized oleic acid (monounsaturated FA) (MUFA), though more data is needed. Some lipids could be used as markers of cancer emergence (plasma lipid species as promising diagnostic markers for prostate cancer, cancer-associated glycosphingolipids as tumor markers, and a combination of serum lipids and cancer antigens as a novel marker for the diagnosis of colon cancers). Emerging therapies, such as lipid nanoparticle synthesis, show promise for targeted drug delivery and disease resolution. A lot to think about.
  • Future research aims to create personalized lipid-based therapies by gaining a profound understanding of lipid interplay with different cellular components. The essential is to study lipids within a modern interdisciplinary scientific framework, integrating insights from multiple fields to decipher their many vital functions in biology.
  • There are many themes to explore. We provided some examples to inspire you, but you are also welcome to submit your original research or comprehensive review articles within this broad area.

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. Biology 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 2700 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.
