Special Issue Information

Dear Colleagues,

Metabolic syndrome (MetS) is a multifactorial condition characterized by a constellation of risk factors—including central obesity, dyslipidemia, insulin resistance, and hypertension—which predispose individuals to cardiovascular diseases, type 2 diabetes, and increased susceptibility to infections. Emerging molecular research has revealed intricate links between MetS and sepsis, highlighting how chronic metabolic inflammation compromises immune responses. Intriguingly, the so-called “obesity paradox”—where obese patients sometimes exhibit better outcomes in acute illnesses such as sepsis—adds a layer of complexity to our understanding of metabolic–immune interactions. This Special Issue aims to gather high-quality studies that delve into the molecular mechanisms underlying MetS, with a focus on inflammation, mitochondrial dysfunction, immune–metabolic crosstalk, and therapeutic interventions. Both experimental (animal and cellular models) and clinical research studies are welcome. We encourage contributions that challenge conventional views and provide novel insights into the paradoxes and pathophysiology of MetS in diverse disease contexts.

Original research papers and comprehensive, up-to-date review articles are welcome.

I look forward to receiving your contributions.

Prof. Dr. Phileno Pinge-Filho

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 250 words) can be sent to the Editorial Office for assessment.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.

Abstract
Secondary bile acids are generated from the metabolism of primary bile acids by intestinal flora and play important roles in lipid digestion, regulation of metabolic homeostasis, and intestinal-hepatic axis signaling.

Secondary bile acids are generated from the metabolism of primary bile acids by intestinal flora and play important roles in lipid digestion, regulation of metabolic homeostasis, and intestinal-hepatic axis signaling. Recent studies indicate that lithocholic acid (LCA) and its derivatives (e.g., 3-oxoLCA and isoLCA) are significantly dysregulated in inflammatory bowel disease, nonalcoholic fatty liver disease, and hepatocellular carcinoma. Consequently, LCA species are emerging as promising biomarkers and potential targets for early diagnosis. This review systematically summarizes the metabolic pathways of LCA species, their distribution and concentrations in human blood, urine, and fecal samples, as well as the progress of recent research studies on enterohepatic disorders, which will serve as a reference for the development of new diagnostic and therapeutic methods in the future.
