Special Issue Information

Dear Colleagues,

Liver functions are finely tuned by environmental stimuli, which translate into adaptative cellular behaviors partly through modulation of their transcriptome. While these mechanisms have historically been studied in detail in hepatocytes, current efforts also aim to better define how the activities of additional liver cell types are controlled. Indeed, cells of the non-parenchymal fraction and their inter-cellular cross-talks with hepatocytes are increasingly being defined as central components in healthy and injured livers. In this context, liver physiological activities, regenerative capacity, and alterations in acute or chronic conditions are driven by coordinated molecular changes in the different liver cell types. These mechanisms are now investigated at (multi-)omics levels, allowing us to obtain novel insights into the molecular control of liver cells’ activities. A previous Special Issue, entitled “Cellular and Molecular Mechanisms Governing Liver Pathophysiology”, was very successful, comprising 10 papers and reviews concerning various aspects of liver pathophysiology. However, mechanisms related to liver pathophysiology are complicated and dynamic, making them difficult to cover in one Special Issue. Therefore, we aim to work towards creating an additional Special Issue on this topic.

The purpose of this Special Issue is to highlight recent findings that shed light on how the functions of hepatocytes and non-parenchymal cells are controlled at the molecular level to trigger adaptative or maladaptive responses in liver pathophysiology. We welcome the submission of both original research articles and reviews. All scientists working in these fields are cordially invited to submit their manuscripts.

All papers will be published on an ongoing basis with full open access. We look forward to receiving your interesting contributions.

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. Cells is an international peer-reviewed open access semimonthly 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.

Treatment strategies for steatohepatitis are of special interest given the high prevalence of obesity and fatty liver disease worldwide. This study aimed to investigate the potential therapeutic mechanism of L-carnitine (LC) and Ginkgo biloba leaf extract (GB) supplementation in ameliorating the adverse effects of hyperlipidemia and hepatosteatosis induced by a high-cholesterol diet (HCD) in an animal model. The study involved 50 rats divided into five groups, including a control group, a group receiving only an HCD, and three groups receiving an HCD along with either LC (300 mg LC/kg bw), GB (100 mg GB/kg bw), or both. After eight weeks, various parameters related to lipid and glucose metabolism, antioxidant capacity, histopathology, immune reactivity, and liver ultrastructure were measured. LC + GB supplementation reduced serum total cholesterol, triglyceride, low-density lipoprotein cholesterol, glucose, insulin, HOMA-IR, alanine transaminase, and aspartate transaminase levels and increased high-density lipoprotein cholesterol levels compared with those in the HCD group. Additionally, treatment with both supplements improved antioxidant ability and reduced lipid peroxidation. The histological examination confirmed that the combination therapy reduced liver steatosis and fibrosis while also improving the appearance of cell organelles in the ultrastructural hepatocytes. Finally, the immunohistochemical analysis indicated that cotreatment with LC + GB upregulated the immune expression of GLP-1 and β-Cat in liver sections that were similar to those of the control animals. Mono-treatment with LC or GB alone substantially but not completely protected the liver tissue, while the combined use of LC and GB may be more effective in treating liver damage caused by high cholesterol than either supplement alone by regulating hepatic oxidative stress and the protein expression of GLP-1 and β-Cat.
