Special Issue Information

Dear Colleagues,

This Special Issue, “Recent Advances in Adipokines (3nd Edition)”, will cover a selection of original research articles and review articles related to adipokines.

Soluble proteins produced from adipose tissue are referred to as adipokines irrespective of their cellular source. White fat tissue is organized into different depots in the body. Subcutaneous and visceral adipose tissues are the best-studied compartments. Adipose tissues are also localized around organs, such as the heart and kidneys. Brown adipose tissue differs greatly from white fat and has its own set of secreted hormones, the so-called “brown adipokines”.

To date, more than 500 adipokines have been described, and most of them are associated with overweight/obesity. Whilst levels of various adipokines are increased in the serum of the obese, others decline. Associations between adipokines and cardiovascular diseases, insulin resistance, different types of cancers, and many more diseases have been identified. Further research has focused on the role of these proteins in immune responses, in autoimmune diseases, and as antimicrobial peptides. Adipokines in serum, plasma, saliva, or urine may emerge as diagnostic and/or prognostic biomarkers for various diseases.

Adipokine receptors are mostly not well characterized. Cell type and tissue expression, regulation using different metabolites, and signalling pathways have to be studied in more detail. Adipokine receptor agonists/antagonists may finally become new therapeutic targets.

Abstract
Background/Objectives: C1q/TNF-related protein 3 (CTRP3), progranulin (PGRN), and chemerin are adipokines that participate in systemic inflammation. This study systematically examined adipokine levels in cystic fibrosis patients of different ages to evaluate their role in inflammatory, metabolic, and hepatic processes. Thirty-seven pediatric and [...] Read more.
Background/Objectives: C1q/TNF-related protein 3 (CTRP3), progranulin (PGRN), and chemerin are adipokines that participate in systemic inflammation. This study systematically examined adipokine levels in cystic fibrosis patients of different ages to evaluate their role in inflammatory, metabolic, and hepatic processes. Thirty-seven pediatric and thirty-three adult CF patients were enrolled to assess the potential of these adipokines as biomarkers. Methods: Anthropometric and physiological data, pulmonary function (forced expiratory volume, FEV1; vital capacity, VC), and liver fibrosis score FIB-4 were assessed. Liver stiffness was measured by transient elastography. Serum samples from 40 healthy adult volunteers served as the control group. Serum concentrations of chemerin, CTRP3, and PGRN were quantified by enzyme-linked immunosorbent assay (ELISA). Results: Compared with healthy controls, adults with CF had markedly lower circulating CTRP3 levels, whereas PGRN concentrations were significantly higher. Among CF patients, both CTRP3 and PGRN were higher in the pediatric group than in adults, while chemerin did not vary with age. The presence of cystic fibrosis-related liver disease (CFLD) did not significantly alter adipokine levels relative to CF patients without liver disease. Receiver operator characteristic (ROC) analysis showed that circulating PGRN could reliably differentiate CF patients from controls; none of the three adipokines predicted the presence of CFLD. CTRP3 and PGRN were inversely correlated with age, BMI, and pulmonary function. Conclusions: Overall, our data support systemic PGRN as a potential biomarker for CF and indicate an age-dependent regulation of circulating CTRP3 and PGRN. Both proteins were inversely associated with BMI, inflammatory markers, liver fibrosis, and pulmonary capacity. Full article

Background/Objectives: Resistin is an adipokine involved in obesity pathogenesis, but its effects on blood and colostrum immune cells from obese mothers remain unclear. This study evaluated the functional activity of phagocytes modulated by resistin in blood and colostrum from overweight and obese mothers. Methods: An observational study was conducted with 82 postpartum women divided according to pregestational BMI into control, overweight, and obese groups. Blood and colostrum samples were collected to determine resistin levels and assess the functional activity of mononuclear (MN) cells. Results: Plasma resistin levels were higher in overweight mothers, whereas colostrum levels were lower in obese mothers. Resistin treatment enhanced superoxide release in both colostrum and blood phagocytes, independent of maternal weight status. In the presence of enteropathogenic Escherichia coli (EPEC), resistin-treated phagocytes from both colostrum and maternal blood showed increased superoxide production. In blood cells from overweight mothers, resistin reduced superoxide dismutase (SOD) concentration, while in colostrum, the highest SOD levels were observed in cultures of resistin-treated cells from mothers with altered weight, regardless of weight status. Blood and colostrum cells treated with resistin increased phagocytosis rates. In colostrum, resistin-treated cells from eutrophic mothers showed high microbicidal indices, whereas cells from mothers with altered weight showed reduced microbicidal indices. In colostrum cells, adipokine levels were reduced in the obesity group. Conclusions: Resistin modulates oxidative metabolism and the functional activity of blood and colostrum phagocytes across all maternal weight statuses, suggesting a possible role for resistin in the maternal immune response associated with obesity.

Background/objectives: Endostatin is a cleavage product of collagen XVIII and a potent anti-angiogenic factor. Angiogenesis is essential for adipose tissue growth and contributes to liver fibrosis and cancer, suggesting a potential therapeutic role for endostatin in obesity, chronic liver diseases, and hepatocellular carcinoma (HCC). This review article summarises published data on the role and expression of endostatin in obesity, liver injury, and HCC. Methods: PubMed and Google databases were searched using the terms “endostatin and liver”, “endostatin and HCC”, “endostatin and obesity”, and “endostatin and adipose”. Studies published in peer-reviewed journals relevant to this review were considered and reviewed for valuable insights. Results: Endostatin is much more than an inhibitor of angiogenesis; it exerts direct effects on adipocytes and myofibroblasts. Endostatin inhibits adipose tissue growth, and studies using Endostar—a modified form of endostatin approved in China for treating lung cancer—have demonstrated its protective effect in liver fibrosis. However, other studies have shown that endostatin activates hepatic stellate cells, indicating a role in tissue regeneration. Most research on endostatin has focused on cancer, and animal and human studies have shown the benefits of Endostar therapy in HCC. Conclusions: Endostar is a promising treatment for HCC and may also become an attractive drug for liver fibrosis. Hence, angiostatic therapy is not without risks and may only be suitable for selected patients. Full article

Adipose tissue is characterized by specialized lipid handling cells called adipocytes, which function as the primary energy reservoir. Like many other cell types, adipocytes have highly plastic properties, such as the conversion of white adipocytes into brown or beige adipocytes, which produce heat, and pink adipocytes into mammary cells synthesizing and secreting milk. Highly specialized adipose tissue depots are present in various species, such as male orangutans with prominent fat-filled facial flanges indicating hierarchical status, or cetaceans with the melon, a specialized adipose tissue for echolocation. Adipose tissue is now considered a true endocrine organ that regulates various physiological mechanisms through the hormonal secretion of adipokines, which modulate systemic metabolism and physiological processes. In particular, the role of adipokines in the control of the reproductive axis and their participation in the regulation of fertility have been widely reported. This review summarizes the current state of research on the effects of adipose-specific cytokines on the male and female reproductive systems. Full article
