From LAL-D to MASLD: Insights into the role of LAL and Kupffer cells in liver inflammation and lipid metabolism

Article

Author: Schwarz, Birgit ; Larsen, Martin R. ; Kratky, Dagmar ; Rainer, Silvia ; Kuentzel, Katharina B. ; Pirchheim, Anita ; Bradić, Ivan ; Trauner, Michael ; Vujić, Nemanja ; Kuentzel, Katharina B ; Larsen, Martin R

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a prevalent liver pathology worldwide, closely associated with obesity and metabolic disorders. Increasing evidence suggests that macrophages play a crucial role in the development of MASLD. Several human studies have shown an inverse correlation between circulating lysosomal acid lipase (LAL) activity and MASLD. LAL is the sole enzyme known to degrade cholesteryl esters (CE) and triacylglycerols in lysosomes. Consequently, these substrates accumulate when their enzymatic degradation is impaired due to LAL deficiency (LALD). This study aimed to investigate the role of hepatic LAL activity and liver-resident macrophages (i.e., Kupffer cells (KC)) in MASLD. To this end, we analyzed lipid metabolism in hepatocyte-specific (hep)Lal-/- mice and depleted KC with clodronate treatment. When fed a high-fat/high-cholesterol diet (HF/HCD), hepLal-/- mice exhibited CE accumulation and an increased number of macrophages in the liver and significant hepatic inflammation. KC were depleted upon clodronate administration, whereas infiltrating/proliferating CD68-expressing macrophages were less affected. This led to exacerbated hepatic CE accumulation and dyslipidemia, as evidenced by increased LDL-cholesterol concentrations. Along with proteomic analysis of liver tissue, these findings indicate that hepatic LAL-D in HF/HCD-fed mice leads to macrophage infiltration into the liver and that KC depletion further exacerbates hepatic CE concentrations and dyslipidemia.

Macrophage-derived amphiregulin promoted the osteogenic differentiation of chondrocytes through EGFR/Yap axis and TGF-β activation

Article

Author: Dong, Wei ; Yang, Chang ; Wang, Xinru ; Wang, Xinyi ; Wang, Shuo ; Mu, Hailin ; Wang, Jaiwei

Endochondral ossification represents a crucial biological process in skeletal development and bone defect repair. Macrophages, recognized as key players in the immune system, are now acknowledged for their substantial role in promoting endochondral ossification within cartilage. Concurrently, the epidermal growth factor receptor (EGFR) ligand amphiregulin (Areg) has been documented for its contributory role in restoring bone tissue homeostasis post-injury. However, the mechanism by which macrophage-secreted Areg facilitates bone repair remains elusive. In this study, the induction of macrophage depletion through in vivo administration of clodronate liposomes was employed in a standard open tibial fracture mouse model to assess bone healing using micro-computed tomography (micro-CT) analysis, histomorphology, and ELISA serum evaluations. The investigation revealed sustained expression of Areg during the fracture healing period in wild-type mice. Macrophage depletion significantly reduced the number of macrophages on the local bone surface and vital organs. This reduction led to diminished Areg secretion, decreased collagen production, and delayed fracture healing. However, histological and micro-CT assessments at 7 and 21 days post-local Areg treatment exhibited a marked improvement of bone healing compared to the vehicle control. In vitro studies demonstrated an increase of Areg secretion by the Raw264.7 cells upon ATP stimulation. Indirect co-culture of Raw264.7 and ATDC5 cells indicated that Areg overexpression enhanced the osteogenic potential of chondrocytes, and vice versa. This osteogenic promotion was attributed to Areg's activation of the membrane receptor EGFR in the ATDC5 cell line, the enhanced phosphorylation of transcription factor Yap, and the facilitation of the expression of bioactive TGF-β by chondrocytes. Collectively, this research elucidates the direct mechanistic effects of macrophage-secreted Areg in promoting bone homeostasis following bone injury.

BACKGROUNDMacrophages play a pivotal role in the development and recovery of acute lung injury (ALI), wherein their phenotypic differentiation and metabolic programming are orchestrated by mitochondria. Specifically, the mitochondrial calcium uniporter (MCU) regulates mitochondrial Ca²⁺ (_mCa²⁺) uptake and may bridge the metabolic reprogramming and functional regulation of immune cells. However, the precise mechanism on macrophages remains elusive. Shikonin, a natural naphthoquinone, has demonstrated efficacy in mitigating ALI and suppressing glycolysis in macrophages, yet which mechanism remains to be fully elucidated.PURPOSEThis study explored whether Shikonin ameliorated ALI via modulating MCU-mediated _mCa²⁺ and macrophage polarization.METHODSThis study firstly examined the protective effects of Shikonin on LPS-induced ALI mice, and investigated whether it is depends on macrophage by depleting macrophage using clodronate liposomes. The regulatory effect of Shikonin on macrophage polarization and mitochondrial MCU/Ca²⁺ signal was testified on RAW264.7 cells, and further validated by knocking-down MCU expression or by using RU360, an MCU inhibitor. Additionally, the crucial role of MCU in the therapeutic effect of Shikonin, along with its regulation on macrophage polarization was validated in mice with LPS-induced ALI under the intervention of RU360.RESULTSShikonin alleviated LPS-induced mice ALI, down-regulated inflammatory cytokines and inhibited the pro-inflammatory polarization of macrophages. Intravenous injection of clodronate liposomes on mice abolished the protective effects of Shikonin on ALI. On RAW264.7 cells, LPS&IFN decreased the protein expression of MCU, while induced pro-inflammatory polarization and glycolytic metabolism. In contrast, Shikonin increased MCU expression, activated MCU-mediated _mCa²⁺ signal, promoted the polarization of macrophages to anti-inflammatory M2 phenotype, and driven a metabolic shift from glycolysis to oxidative phosphorylation. Either knocking-down MCU expression or pharmacological inhibiting MCU by using RU360 mitigated the effects of Shikonin on Raw 264.7 cells. Furthermore, RU360 counteracted the ameliorative effect of Shikonin on ALI mice.CONCLUSIONThe current data showed that Shikonin alleviated LPS-induced mice ALI by activating mitochondrial MCU/_mCa²⁺ signal and regulating macrophage metabolism.

Credit: RealPeopleGroup via Getty Images The Italian pharmaceutical company Abiogen Pharma completed an acquisition of a 97.09% stake in the Swiss orphan conditions-focused EffRx Pharmaceuticals on May 29. This deal follows Abiogen’s recent acquisition of the Cologne, Germany-based Altamedics in December 2022. Altamedics specialises in pharmaceutical distribution in hospital settings. The €8 million ($8,559,480) deal was Abiogen’s first move in its global expansion plan and the deal with EffRx is a continuation of this. Abiogen Pharma specialises in osteoarticular and bone metabolism diseases amongst other therapy areas. The company has developed three bisphosphonates, clodronate, alendronate and Nerixia (neridronate), for the treatment of bone pathologies such as osteoarthritis . Bisphosphonates are drugs that slow the progression of bone loss. EffRx has received several European regulatory approvals for drugs in its portfolio . For example, in July 2022, EffRx launched its paediatric adrenal insufficiency replacement therapy Alkindi (hydrocortisone) in Switzerland. Alkindi is one of EffRx’s three marketed drugs. The company developed and launched Binosto (alendronate sodium) as the first and only buffered solution for osteoporosis. The European Medicines Agency has also approved Efmody for the treatment of congenital adrenal hyperplasia medicine in patients ages 12 years and above in the European Union. The company’s last deal included an exclusive license agreement with the Cardiff, UK-headquartered specialty pharmaceuticals company Diurnal group for the commercialisation of Efmody (hydrocortisone) in Switzerland. In Italy, Abiogen began distributing its bisphosphonates in 2014 and has since seen some successful drug approvals. The biotech transferred the rights for alendronate to Merck which marketed the drug under the brand name Vancapsi. The Italian health authorities also gave Abiogen’s Nerixia the country’s first rare disease designation for Osteogenesis Imperfecta and Complex regional pain syndrome, for which the drug is now approved in Italy. Separate from drug development, the Italian company also offers contract manufacturing and clinical supply services. In a press release , Abiogen’s International Business Unit Head, Prisca Di Martino said, “We are working towards developing Abiogen into an international business, without losing sight of our nature as an Italian and family-run undertaking, and we are pursuing this target by entering into agreements with foreign businesses that share our goals and therapeutic areas.”

Study shows that selection of breast cancer patients for adjuvant bisphosphonate therapy based on Inbiomotion's MAFTEST® reduces the risk of death in comparison with current clinical guidance

MAFTEST® analyses of the NSABP-B34 and AZURE landmark clinical trials confirmed clinical utility of the MAFTEST® for selection of early-stage breast cancer patients that benefit from adjuvant clodronate treatment. Reduces the risk of death at 5 and 10 years by 26% and 23% respectively. Identifies almost twice as many patients able to benefit from the intervention than are selected using current clinical guidelines. Data published in Annals of Oncology, (33), SUPPLEMENT 3, S152, 2022. BARCELONA, Spain, July 14, 2022 /PRNewswire/ -- Inbiomotion SL, a company developing a unique single-gene-based biomarker for the personalized adjuvant treatment of early-stage (stage I-III) breast cancer patients, announces the results of comparing the clinical efficacy of implementing the proprietary MAFTEST® for selection of patients for adjuvant bisphosphonates therapy with current clinical guidance. The results were presented at the ESMO 2022 Breast Cancer Symposium. The data show that stratification of early breast cancer patients according to MAF status reduced the risk of death and relapse in MAF negative patients by 26% and 23% respectively, compared to a 12% and 15% reduction in the risk of death or relapse seen with stratification by menopausal status recommended by current ESMO and ASCO Clinical Guidelines. The data also indicate that adjuvant treatment with bisphosphonates should be avoided in MAF positive patients as the risk of death and relapse is increased 16% and 15% respectively in these patients. In addition, the study shows that the use of MAF status for selection of early breast cancer patients for treatment with bisphosphonates allows the treatment of young premenopausal patients currently excluded by existing clinical guidance. "The MAF biomarker allows a new paradigm for selection of patients for adjuvant bisphosphonate treatment of early breast cancer that not only identifies those patients that will benefit from treatment (MAF negatives) but also excludes patients that could be harmed (MAF positives). This new selection criteria not only reduces the risk of death and relapse for selected patients but also provides a new treatment option for young patients currently excluded from this treatment in current clinical practice," said Robert Coleman, Professor Emeritus, Department of Oncology and Metabolism, University of Sheffield, UK. Currently, clodronate and other bisphosphonates are not approved by the regulatory agencies for use in adjuvant treatment of the broad population of early-stage breast cancer patients. However, they are recommended in the ASCO/CCO and ESMO clinical guidelines for adjuvant treatment of breast cancer in postmenopausal patients. The study shows that identifying MAF-negative patients for selection for adjuvant treatment with bisphosphonates outperforms current selection by menopausal status and could give more patients, particularly younger patients, the opportunity to benefit from adjuvant bisphosphonates, while avoiding potential harm (or no benefit), than solely using menopausal status as a selection criterion. "Our results indicate that adjuvant clodronate treatment has a large clinical benefit if restricted to MAF-negative patients," said Prof. Alexander Paterson, principal investigator of the NSABP-B34 clinical trial and Emeritus Clinical Professor at the Department of Oncology, University of Calgary. "Our data provide an objective criterion for patient selection for bisphosphonate adjuvant treatment that outperforms current selection based on menopausal status." "This study confirms our previous findings and the clinical utility of MAFTEST® as a unique tool for precision medicine in early breast cancer. Every year approximately 355,000 women are diagnosed with early breast cancer in Europe with a 10% risk of death at 5 years. Using MAF Test these deaths could be reduced by 26%, which would translate to 9,230 lives saved," said Joël Jean-Mairet, Executive Chairman of the Board of Inbiomotion. "We have discovered and developed a new biomarker, MAF gene amplification, that if used as selection criteria for adjuvant treatment with bisphosphonates improves the clinical outcome of breast cancer patients compared with current clinical practice, " said Prof. Roger Gomis, ICREA Research Professor at IRB Barcelona. "MAF Test is a biomarker that is easy to implement in any clinical pathology lab and should be considered for routine characterization of breast cancer tumors." Recently the MAFTEST® obtained the CE-mark as an in vitro diagnostic medical device for prognostic purposes. Since clodronate and other bisphosphonates are not approved by the regulatory agencies for use in adjuvant treatment of early-stage breast cancer patients, Inbiomotion's MAFTEST® is not authorized to be used as a companion diagnostic as described in the above-mentioned study.

Full text article: About Inbiomotion: Inbiomotion SL, a company founded by Prof. Roger Gomis, is developing a unique single gene-based biomarker for the personalized adjuvant treatment of early-stage breast cancer patients. The biomarker has been technically and analytically validated. The results of the first trial using well annotated archived specimens of the AZURE registrational clinical trial, now confirmed in the NSABP-B34 trial, indicate its potential use as a companion diagnostic. The company holds over 200 patents and patent applications covering its proprietary FISH MAFTEST® and the use of bisphosphonates in the adjuvant treatment of early-stage breast cancer patients. About MAF: MAF (mesenchymal aponeurotic fibrosarcoma gene, an AP-1 family transcription factor) is expressed in primary cancer tumors. This is associated with increased metastasis, especially bone metastasis. MAF transcriptionally controls genes such PTHrP, which regulate metastasis-related cellular processes, including survival, initiation, metabolic rewiring, and particularly, adhesion to bone marrow–derived cells and osteoclast differentiation. These observations point to MAF having a key hierarchical role in metastasis. SOURCE Inbiomotion
