Abstract
Macrophages are critical in mediating immune and inflammatory responses, while monocyte-to-macrophage differentiation is one of the main macrophage resources that involves various matrix proteins. Matrix remodeling associated 7 (MXRA7) was recently discovered to affect a variety of physiological and pathological processes related to matrix biology. In the present study, we investigated the role of MXRA7 in monocyte-to-macrophage differentiation in vitro. We found that knockdown of MXRA7 inhibited the proliferation of THP-1 human monocytic cells. Knockdown of MXRA7 increased the adhesion ability of THP-1 cells through upregulation the expression of adhesion molecules VCAM-1 and ICAM1. Knockdown of MXRA7 alone could promoted the differentiation of THP-1 cells to macrophages. Furthermore, the MXRA7-knockdown THP-1 cells produced a more significant upregulation pattern with M1-type cytokines (TNF-α, IL-1β and IL-6) than with those M2-type molecules (TGF-β1 and IL-1RA) upon PMA stimulation, indicating that knockdown of MXRA7 facilitated THP-1 cells differentiation toward M1 macrophages. RNA sequencing analysis revealed the potential biological roles of MXRA7 in cell adhesion, macrophage and monocyte differentiation. Moreover, MXRA7 knockdown promoted the expression of NF-κB p52/p100, while PMA stimulation could increase the expression of NF-κB p52/p100 and activating MAPK signaling pathways in MXRA7 knockdown cells. In conclusion, MXRA7 affected the differentiation of THP-1 cells toward macrophages possibly through NF-κB signaling pathways.

Abstract
Mounting evidence underscores the intricate interplay between the immune system and skeletal muscles in Duchenne muscular dystrophy (DMD), as well as during regular muscle regeneration. While immune cell infiltration into skeletal muscles stands out as a prominent feature in the disease pathophysiology, a myriad of secondary defects involving metabolic and inflammatory pathways persist, with the key players yet to be fully elucidated. Steroids, currently the sole effective therapy for delaying onset and symptom control, come with adverse side effects, limiting their widespread use. Preliminary evidence spotlighting the distinctive features of T cell profiling in DMD prompts the immuno-characterization of circulating cells. A molecular analysis of their transcriptome and secretome holds the promise of identifying a subpopulation of cells suitable as disease biomarkers. Furthermore, it provides a gateway to unraveling new pathological pathways and pinpointing potential therapeutic targets. Simultaneously, the last decade has witnessed the emergence of novel approaches. The development and equilibrium of both innate and adaptive immune systems are intricately linked to the gut microbiota. Modulating microbiota-derived metabolites could potentially exacerbate muscle damage through immune system activation. Concurrently, genome sequencing has conferred clinical utility for rare disease diagnosis since innovative methodologies have been deployed to interpret the functional consequences of genomic variations. Despite numerous genes falling short as clinical targets for MD, the exploration of Tdark genes holds promise for unearthing novel and uncharted therapeutic insights. In the quest to expedite the translation of fundamental knowledge into clinical applications, the identification of novel biomarkers and disease targets is paramount. This initiative not only advances our understanding but also paves the way for the design of innovative therapeutic strategies, contributing to enhanced care for individuals grappling with these incapacitating diseases.

Abstract
The biology of the matrix remodeling-associated 7 (MXRA7) gene has been ill defined. Bioinformatic analysis of public data sets revealed that MXRA7 messenger RNA (mRNA) was highly expressed in acute myeloid leukemia (AML), especially acute promyelocytic leukemia (APL). High expression of MXRA7 was associated with poor overall survival of patients with AML. We confirmed that MXRA7 expression was upregulated in patients with APL and cell lines. Knockdown or overexpression of MXRA7 did not affect the proliferation of NB4 cells directly. Knockdown of MXRA7 in NB4 cells promoted drug-induced cell apoptosis, whereas overexpression of MXRA7 had no obvious influence on drug-induced cell apoptosis. Lowering MXRA7 protein levels in NB4 cells promoted all-trans retinoic acid (ATRA)-induced cell differentiation possibly through decreasing the PML-RARα level and increasing PML and RARα levels. Correspondingly, overexpression of MXRA7 showed consistent results. We also demonstrated that MXRA7 altered the expression of genes involved in leukemic cell differentiation and growth. Knockdown of MXRA7 upregulated the expression levels of C/EBPB, C/EBPD, and UBE2L6, and downregulated the expression levels of KDM5A, CCND2, and SPARC. Moreover, knockdown of MXRA7 inhibited the malignancy of NB4 cells in a non-obese diabetic-severe combined immune-deficient mice model. In conclusion, this study demonstrated that MXRA7 influences the pathogenesis of APL via regulation of cell differentiation. The novel findings about the role of MXRA7 in leukemia not only shed light on the biology of this gene but also proposed this gene as a new target for APL treatment.

Abstract
An increasing number of patients develop an atherothrombotic myocardial infarction (MI) in the absence of standard modifiable risk factors (SMuRFs). Monocytes and macrophages regulate the development of atherosclerosis, and monocytes can adopt a long-term hyperinflammatory phenotype by epigenetic reprogramming, which can contribute to atherogenesis (called "trained immunity"). We assessed circulating monocyte phenotype and function and specific histone marks associated with trained immunity in SMuRFless patients with MI and matched healthy controls. Even in the absence of systemic inflammation, monocytes from SMuRFless patients with MI had an increased overall cytokine production capacity, with the strongest difference for LPS-induced interleukin-10 production, which was associated with an enrichment of the permissive histone marker H3K4me3 at the promoter region. Considering the lack of intervenable risk factors in these patients, trained immunity could be a promising target for future therapy.

Abstract
Matrix remodeling is a critical process in hematopoiesis. The biology of MXRA7, as a matrix remodeling associated gene, has still not been reported in hematopoietic process. Public databases showed that MXRA7 expressed in hematopoietic stem cells, suggesting that it may be involved in hematopoiesis. We found that the amounts of megakaryocytes were lower in bone marrow and spleen from Mxra7-/- mice compared with that from wild-type mice. Knock-out of MXRA7 also reduced the amount of platelet in peripheral blood and affected the function of platelets. Knock-out of MXRA7 inhibited hematopoietic stem/progenitor cells differentiate to megakaryocytes possibly through down-regulating the expression of GATA-1 and FOG-1. Moreover, knockdown of MXRA7 in MEG-01 cells could inhibit the cell proliferation and cell apoptosis. Knockdown of MXRA7 inhibited the differentiation of MEG-01 cells and proplatelet formation through suppressing the ERK/MAPK signaling pathway and the expression of β-tubulin. In conclusion, the current study demonstrated the potential significance of MXRA7 in megakaryocyte differentiation and platelet production. The novel findings proposed a new target for the treatment of platelet-related diseases, and much more investigations are guaranteed to dissect the mechanisms of MXRA7 in megakaryocyte differentiation and platelet production.

Stilbenes, a Versatile Class of Natural Metabolites for Inflammation-An Overview. Molecules 2023; 28:molecules28093786. [PMID: 37175197 PMCID: PMC10180133 DOI: 10.3390/molecules28093786] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2023] [Revised: 04/21/2023] [Accepted: 04/25/2023] [Indexed: 05/15/2023] Open
Abstract
Stilbenes are polyphenolic allelochemicals synthesized by plants, especially grapes, peanuts, rhubarb, berries, etc., to defend themselves under stressful conditions. They are now exploited in medicine for their antioxidant, anti-proliferative and anti-inflammatory properties. Inflammation is the immune system's response to invading bacteria, toxic chemicals or even nutrient-deprived conditions. It is characterized by the release of cytokines which can wreak havoc on healthy tissues, worsening the disease condition. Stilbenes modulate NF-κB, MAPK and JAK/STAT pathways, and reduce the transcription of inflammatory factors which result in maintenance of homeostatic conditions. Resveratrol, the most studied stilbene, lowers the Michaelis constant of SIRT1, and occupies the substrate binding pocket. Gigantol interferes with the complement system. Besides these, oxyresveratrol, pterostilbene, polydatin, viniferins, etc., are front runners as drug candidates due to their diverse effects from different functional groups that affect bioavailability and molecular interactions. However, they each have different thresholds for toxicity to various cells of the human body, and thus a careful review of their properties must be conducted. In animal models of autoinflammatory diseases, the mode of application of stilbenes is important to their absorption and curative effects, as seen with topical and microemulsion gel methods. This review covers the diversity seen among stilbenes in the plant kingdom and their mechanism of action on the different inflammatory pathways. In detail, macrophages' contribution to inflamed conditions in the liver, the cardiac, connective and neural tissues, in the nephrons, intestine, lungs and in myriad other body cells is explored, along with detailed explanation on how stilbenes alleviate the symptoms specific to body site. A section on the bioavailability of stilbenes is included for understanding the limitations of the natural compounds as directly used drugs due to their rapid metabolism. Current delivery mechanisms include sulphonamides, or using specially designed synthetic drugs. It is hoped that further research may be fueled by this comprehensive work that makes a compelling argument for the exploitation of these compounds in medicine.

Abstract
Wound healing depends largely on the remodeling of the extracellular matrix around and reorganization of tissue-resident cells. Matrix remodeling associated 7 (MXRA7) is a member of the matrix remodeling-associated gene family and is involved in matrix remodeling-associated processes, such as inflammatory neovascularization, liver injury, and autoimmune skin disease. To investigate whether and how MXRA7 participate in cutaneous wound healing, an ear-punching model was utilized in wild-type (WT) and MXRA7-deficient mice, and the dermal fibroblasts from these mice were further studied in vitro. Results showed that the MXRA7 deficiency impaired the wound healing process in mice. Quantitative PCR indicated that lack of MXRA7 impaired the expression of several extracellular matrix genes (e.g., MMP-2) and inhibited signaling pathways (e.g., STAT3) in healing ear tissues. In in vitro culture system, migration, contraction, or proliferation of fibroblasts was impaired upon MXRA7 deficiency. Pull-down and mass spectrum assay revealed that vimentin was among the proteins that bound MXRA7 proteins in cells, and further investigations indicate MXRA7 was an autocrine factor in fibroblasts that involved vimentin in certain ways, such as JNK and STAT3/STAT5 signaling pathways in our study. In conclusion, MXRA7 proteins promote wound healing through vimentin in coordinating fibroblast functions.

Abstract
Background:Zornia diphylla (L.) Pers. (ZDP) is a traditional Chinese herbal medicine that has been used for several decades to treat patients with liver diseases. Whether ZDP is best administered as a single agent or adjunctive therapy has yet to be determined as does the mechanism whereby it exerts its effects on antagonizing acute liver injury (ALI). Aim of the study: To investigate the protective effects of ZDP on ALI induced by carbon tetrachloride (CCl4) and the potential underlying mechanisms. Materials and Methods: Sixty adult mice were randomized into six study groups (n = 10/group). Three groups were treated with different concentrations of ZDP (2.5, 1.25, 0.625 g/kg), one with bifendate (0.0075 g/kg) alone (positive control) and one with physiologic saline (normal, negative control). All groups were treated for 14 days. Two hours after the last administration, the normal group received an intraperitoneal injection of peanut oil, and the other five groups received an intraperitoneal injection of an equal dose of CCl4 peanut oil solution. At 24 h, the liver index, histology and serum or tissue levels and/or protein expression of aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin (TBIL), alkaline phosphatase (ALP), superoxide dismutase (SOD), malondialdehyde (MDA), catalase (CAT), glutathione (GSH), Akt, phosphorylated Akt (p-Akt), nuclear factor kappa B p65 (NF-κB p65), inhibitor of NF-κB α (IκB-α), interleukin-1 β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor α (TNF-α), E-cadherin and vimentin were determined. Results: Compared to the model controls, the degree of inflammatory cell infiltration and hepatocyte injury of liver tissue was relieved in the bifendate and three ZDP groups; liver index in the ZDP (2.5, 1.25 g/kg) groups and serum liver function indices in the ZDP (2.5, 1.25 and 0.625 g/kg) groups were decreased; antioxidants SOD, CAT and GSH in liver tissue were increased but the lipid peroxidation index MDA was decreased; protein expression of inflammatory cytokines Akt, p-Akt, NF-κB p65, IκB-α, IL-1β, IL-6 and TNF-α in the liver was ameliorated, and E-cadherin expression was increased. The results of liver histopathology also showed that ZDP had a significant effect on ALI. Conclusion: ZDP has obvious protective effects on CCl4-induced ALI as a single therapy and appears to act by inhibiting oxidation, reducing the release of inflammatory factors and promoting hepatocyte repair.

In-Depth Analysis of the Plasma Proteome in ME/CFS Exposes Disrupted Ephrin-Eph and Immune System Signaling. Proteomes 2021; 9:proteomes9010006.

Abstract
Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a disabling disease with worldwide prevalence and limited therapies exclusively aimed at treating symptoms. To gain insights into the molecular disruptions in ME/CFS, we utilized an aptamer-based technology that quantified 4790 unique human proteins, allowing us to obtain the largest proteomics dataset yet available for this disease, detecting highly abundant proteins as well as rare proteins over a nine-log dynamic range. We report a pilot study of 20 ME/CFS patients and 20 controls, all females. Significant differences in the levels of 19 proteins between cohorts implicate pathways related to the extracellular matrix, the immune system and cell-cell communication. Outputs of pathway and cluster analyses robustly highlight the ephrin pathway, which is involved in cell-cell signaling and regulation of an expansive variety of biological processes, including axon guidance, angiogenesis, epithelial cell migration, and immune response. Receiver Operating Characteristic (ROC) curve analyses distinguish the plasma proteomes of ME/CFS patients from controls with a high degree of accuracy (Area Under the Curve (AUC) > 0.85), and even higher when using protein ratios (AUC up to 0.95), that include some protein pairs with established biological relevance. Our results illustrate the promise of plasma proteomics for diagnosing and deciphering the molecular basis of ME/CFS.

Abstract
Arachidonic acid (AA) signaling pathway is an important constituent of inflammatory processes. In our previous study, it was found that dihydro-stilbene gigantol relieved hepatic inflammation in mice with CCl4-induced acute liver injury. This study aimed to investigate the involvement of arachidonate metabolic cascade in this process. Our results showed CCl4 activated AA metabolism with the evidence of cPLA2 phosphorylation, which was dependent on the MAPK/JNK activation. Pretreatment with JNK inhibitor SU3327 or gigantol abolished the cPLA2 activation, along with the attenuation of liver damage. Besides, gigantol markedly decreased immune cells activation. Metabolomic analysis revealed that gigantol universally reversed the upregulation of major AA metabolites in injured mouse livers induced by CCl4, especially 12-hydroxyeicosatetraenoic acid (12-HETE). Gigantol also decreased the mRNA and protein expression of platelet-, and leukocyte-type 12-lipoxxygenase (LOX) in the liver. Furthermore, pan-LOX inhibitor nordihydroguaiaretic acid (NDGA) and specific 12-LOX inhibitors baicalein and ML351 attenuated the liver injury to the same extent as gigantol. Overall, our study elucidated a comprehensive profile of AA metabolites during hepatic inflammation caused by CCl4, highlighting the role of 12-LOX-12-HETE pathway in this process. And gigantol alleviated liver inflammation partly through inhibiting the JNK/cPLA2/12-LOX pathway.

Abstract
Cholestatic liver disease affects millions of people worldwide and stems from a plethora of causes such as immune dysfunction, genetics, cancerous growths, and lifestyle choices. While not considered a classical lymphatic organ, the liver plays a vital role in the lymph system producing up to half of the body's lymph per day. The lymphatic system is critical to the health of an organism with its networks of vessels that provide drainage for lymphatic fluid and routes for surveilling immune cells. Cholestasis results in an increase of inflammatory cytokines, growth factors, and inflammatory infiltrate. Left unchecked, further disease progression will include collagen deposition which impedes both the hepatic and lymphatic ducts, eventually resulting in an increase in hepatic decompensation, increasing portal pressures, and accumulation of fluid within the abdominal cavity (ascites). Despite the documented interplay between these vital systems, little is known about the effect of liver disease on the lymph system and its biological response. This review looks at the current cholestatic literature from the perspective of the lymphatic system and summarizes what is known about the role of the lymph system in liver pathogenesis during hepatic injury and remodeling, immune-modulating events, or variations in interstitial pressures.

Abstract
People with HIV (PWH) are at increased risk for atherosclerotic cardiovascular disease (ASCVD). Proportions of vascular homing monocytes are enriched in PWH; however, little is known regarding monocyte-derived macrophages (MDMs) that may drive atherosclerosis in this population. We isolated PBMCs from people with and without HIV, and cultured these cells for 5 days in medium containing autologous serum to generate MDMs. Differential gene expression (DGE) analysis of MDMs from PWH identified broad alterations in innate immune signaling (IL-1β, TLR expression, PPAR βδ) and lipid processing (LXR/RXR, ACPP, SREBP1). Transcriptional changes aligned with the functional capabilities of these cells. Expression of activation markers and innate immune receptors (CD163, TLR4, and CD300e) was altered on MDMs from PWH, and these cells produced more TNFα, reactive oxygen species (ROS), and matrix metalloproteinases (MMPs) than did cells from people without HIV. MDMs from PWH also had greater lipid accumulation and uptake of oxidized LDL. PWH had increased serum levels of free fatty acids (FFAs) and ceramides, with enrichment of saturated FAs and a reduction in polyunsaturated FAs. Levels of lipid classes and species that are associated with CVD correlated with unique DGE signatures and altered metabolic pathway activation in MDMs from PWH. Here, we show that MDMs from PWH display a pro-atherogenic phenotype; they readily form foam cells, have altered transcriptional profiles, and produce mediators that likely contribute to accelerated ASCVD. People with HIV (PWH) are at greater risk for developing cardiovascular disease (CVD) than the general public, but the mechanisms underlying this increased risk are poorly understood. Macrophages play key roles in the pathogenesis of atherosclerosis, and are potential targets for therapeutic intervention. Here, we investigate phenotypic and functional abnormalities in monocyte-derived macrophages (MDMs) isolated from PWH that may drive CVD risk in this population. MDMs were differentiated in the presence of autologous serum, enabling us to explore the contributions of serum components (lipids, inflammatory cytokines, microbial products) as drivers of altered MDM function. We link serum levels of inflammatory biomarkers and CVD-associated lipid species to MDM activation. Our study provides new insight into drivers of pro-atherogenic MDM phenotype in PWH, and identifies directions for future study and potential intervention strategies to mitigate CVD risk.

Abstract
This study aims to investigate the protective effects of morin hydrate (MH) against acute liver injury induced by carbon tetrachloride (CCl4) in mice and to elucidate the possible molecular mechanism of action. Mice were pretreated with MH (50 mg/kg body weight) or vehicle by oral gavage once daily for 5 days, followed by intraperitoneal injection of a single dose of CCl4 (1 ml/kg in olive oil). Mice were sacrificed 24 h later; the blood and liver samples were harvested for analysis. We also used the model of lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages in vitro and examined the effects of MH and its mechanism of action on the inflammatory response. Our results revealed that MH remarkably attenuated liver histopathological alterations, serum transaminases, hepatocytes death, and inflammatory response induced by CCl4. Importantly, MH reduced expression of the triggering receptor expressed on myeloid cells-1 (TREM-1) and toll-like receptor 4 (TLR4) both in vivo and in vitro experiments. This inhibitory effect MH on expression of the TREM-1 and TLR4 in cell culture was further heightened after TREM-1 knockdown with small interfering RNA (siRNA). Moreover, MH dramatically suppressed the inhibitor of kappa B α (IκBα) degradation and subsequent nuclear factor-kappa B (NF-κB) p65 translocation into the nucleus and NF-κB-mediated cytokines, such as tumor necrosis factor α (TNF-α), interleukin (IL)-1β, and IL-6. Additionally, MH also ameliorated CCl4-induced oxidative stress by enhancing the nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) expression in the injured livers. Taken together, MH has hepatoprotective activity, and this effect may be elicited by attenuating macrophage-mediated inflammatory responses via inhibition TREM-1/TLR4/NF-κB signaling and by regulating hepatic oxidative stress via enhancement Nrf2/HO-1 antioxidant pathway.

Abstract
Preliminary data mining performed with Gene Expression Omnibus data sets implied that psoriasis may involve the matrix remodelling associated 7 (MXRA7), a gene with little function information yet. To test that hypothesis, studies were performed in human samples and murine models. Immunohistochemistry in normal human skin showed that MXRA7 proteins were present across the full epidermal layer, with highest expression level detected in the basal layer. In psoriatic samples, MXRA7 proteins were absent in the basal stem cells layer, while suprabasal keratinocytes were stained at a higher level than in normal tissues. In an imiquimod-induced psoriasis-like disease model in mice, diseased skins manifested similar MXRA7 expression pattern and change as in human samples, and MXRA7-deficient mice developed severer psoriasis-like diseases than wild-type mice did. While levels of propsoriatic genes (eg IL17, IL22, IL23) in imiquimod-stimulated MXRA7-deficient mice were higher than in wild-type mice, keratinocytes isolated from MXRA7-deficient mice showed increased proliferation upon differentiation induction in culture. These data demonstrated that MXRA7 gene might function as a negative modulator in psoriasis development when propsoriatic factors attack, presumably via expression alteration or redistribution of MXRA7 proteins in keratinocytes.

Abstract
The matrix remodeling associated 7 (MXRA7) gene had been ill-studied and its biology remained to be discovered. Inspired by our previous findings and public datasets concerning MXRA7, we hypothesized that the MXRA7 gene might be involved in bone marrow mesenchymal stem cells (BMSCs) functions related to bone formation, which was checked by utilizing in vivo or in vitro methodologies. Micro-computed tomography of MXRA7-deficient mice demonstrated retarded osteogenesis, which was reflected by shorter femurs, lower bone mass in both trabecular and cortical bones compared with wild-type (WT) mice. Histology confirmed the osteopenia-like feature including thinner growth plates in MXRA7-deficient femurs. Immunofluorescence revealed less osteoblasts in MXRA7-deficient femurs. Polymerase chain reaction or western blot analysis showed that when WT BMSCs were induced to differentiate toward osteoblasts or adipocytes in culture, MXRA7 messenger RNA or protein levels were significantly increased alongside osteoblasts induction, but decreased upon adipocytes induction. Cultured MXRA7-deficient BMSCs showed decreased osteogenesis upon osteogenic differentiation induction as reflected by decreased calcium deposition or lower expression of genes responsible for osteogenesis. When recombinant MXRA7 proteins were supplemented in a culture of MXRA7-deficient BMSCs, osteogenesis or gene expression was fully restored. Upon osteoblast induction, the level of active β-catenin or phospho-extracellular signal-regulated kinase in MXRA7-deficient BMSCs was decreased compared with that in WT BMSCs, and these impairments could be rescued by recombinant MXRA7 proteins. In adipogenesis induction settings, the potency of MXRA7-deficient BMSCs to differentiate into adipocytes was increased over the WT ones. In conclusion, this study demonstrated that MXRA7 influences bone formation via regulating the balance between osteogenesis and adipogenesis in BMSCs.

Abstract
Several in vitro studies have shown the potential hepatoprotective properties of eckol, a natural phlorotannin derived from the brown alga. However, the in vivo hepatoprotective potential of eckol has not been determined. In this study, we performed an in vivo study to investigate the protective effect of eckol and its possible mechanisms on the carbon tetrachloride (CCl₄)-induced acute liver injury model in mice. Results revealed that eckol pre-treatment at the dose of 0.5 and 1.0 mg/kg/day for 7 days significantly suppressed the CCl₄-induced increases of alanine transaminase (ALT) and aspartate aminotransferase (AST) levels in serum and meliorated morphological liver injury. Terminal deoxynucleotidyl transferase-mediated dUTP nick end labelling (TUNEL) analysis showed that the number of positive apoptotic hepatocytes in the eckol-treated group was lower than that in the CCl₄ model group. Western blotting analysis also demonstrated the enhanced expression of bcl-2 and suppressed expression of cleaved caspase-3 by eckol. The CCl₄-induced oxidative stress in liver was significantly ameliorated by eckol, which was characterized by reduced malondialdehyde (MDA) formations, and enhanced superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) activities and glutathione (GSH) content. Moreover, the CCl₄-induced elevations of pro-inflammatory cytokines tumor necrosis factor (TNF)-α, interleukin (IL)-1β and IL-6 were markedly suppressed in the eckol-treated group. However, eckol enhanced the level of IL-10, a potent anti-inflammatory cytokine, and recruited CD11c⁺ dendritic cells into the liver tissues of CCl₄-treated mice. These results indicated that eckol has the protective effect on CCl₄-induced acute liver injury via multiple mechanisms including anti-apoptosis, anti-oxidation, anti-inflammation and immune regulation.
