HuoXueTongFu formula induces M2c macrophages via the MerTK/PI3K/AKT pathway to eliminate NETs in intraperitoneal adhesion in mice. JOURNAL OF ETHNOPHARMACOLOGY 2024; 331:118290. [PMID: 38703872 DOI: 10.1016/j.jep.2024.118290] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 05/02/2024] [Accepted: 05/02/2024] [Indexed: 05/06/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE HuoXueTongFu Formula (HXTF) is a traditional Chinese herbal formula that has been used as a supplement and alternative therapy for intraperitoneal adhesion (IA). However, its specific mechanism of action has not been fully understood. AIM OF THE STUDY In surgery, IA presents an inevitable challenge, significantly impacting patients' physical and mental well-being and increasing the financial burden. Our previous research has confirmed the preventive effects of HXTF on IA formation. However, the precise mechanism of its action still needs to be understood. METHODS In this study, the IA model was successfully established by using the Ischemic buttons and treated with HXTF for one week with or without Mer Tyrosine Kinase (MerTK) inhibitor. We evaluated the pharmacodynamic effect of HXTF on IA mice. The MerTK/phosphoinositol 3-kinase (PI3K)/protein kinase B (AKT) pathway-associated proteins were detected by Western blotting. Neutrophil extracellular traps (NETs) were detected by immunofluorescence. Macrophage phenotype was assessed by immunohistochemistry and flow cytometry. Inflammatory cytokines were detected by Real Time Quantitative PCR and Western blotting. RESULTS HXTF reduced inflammatory response and alleviated IA. HXTF significantly enhanced MerTK expression, increased the number of M2c macrophages, and decreased the formation of NETs. In addition, the MerTK/PI3K/AKT pathway was significantly activated by HXTF. However, after using MerTK inhibitors, the role of HXTF in inducing M2c macrophage through activation of the PI3K/AKT pathway was suppressed and there was no inhibitory effect on NETs formation and inflammatory responses, resulting in diminished inhibition of adhesion. CONCLUSION HXTF may improve IA by activating the MerTK/PI3K/AKT pathway to induce M2c polarization, which removes excess NETs and attenuates the inflammatory response.

Abstract
Postoperative peritoneal adhesion is a serious clinical complication. Various hydrogel barriers have been developed to prevent peritoneal adhesion. However, it remains a challenge to design a hydrogel with desirable physicochemical properties and bioactivities. In this study, a zwitterionic polysaccharide-based multifunctional hydrogel is developed using epigallocatechin-3-gallate (EGCG) to prevent postoperative abdominal adhesion. This hydrogel is simple to use and has desirable properties, such as excellent injectability, self-healing, and non-swelling properties. The hydrogel also has ultralow fouling capabilities, such as superior bactericidal performance, cell and protein adhesion, and low immunogenicity resistance. Moreover, the hydrogel exhibits good antioxidant activity, which is attributed to the integration of EGCG. Furthermore, the detailed mechanism from in vivo and in vitro experimental studies illustrates that hydrogel compositions can synergistically prevent adhesion formation through multiple pathways, including anti-inflammatory and antioxidant capabilities and inhibition effects on the mesothelial-mesenchymal transition (MMT) process induced by transforming growth factor (TGF-β). In summary, this zwitterionic multifunctional hydrogel has great potential to prevent postoperative adhesion formation in the clinical setting.

Abstract
Inflammasomes are cytosolic signaling hubs that promote the inflammatory response (i.e. an immune reaction to counteract threats in physiological conditions). Their potential role in lymphomagenesis remains to be elucidated. Depending on the context, innate immune cells, such as macrophages, may induce inflammation that contributes to the anti-tumor function; however, if uncontrolled, inflammation can promote cancer development. Here, we exploited bioinformatic tools, TCGA data, and tumor tissue samples from patients with diffuse large B-cell lymphoma (DLBCL), one of the most frequent non-Hodgkin lymphomas of B-cell origin, to investigate the distribution of the different immune cell subpopulations in DLBCL samples in order to characterize the immune landscape of their microenvironment. We found a clear prominence of macrophages in the DLBCL microenvironment. Particularly, the proportions of resting M0 and pro-inflammatory M1 macrophages were higher in DLBCL than spleen samples (controls). As each inflammasome has unique sensor activation and platform assembly mechanisms, we examined the expression of a large panel of inflammasome actors. We found that inflammasome components, cytokines and Toll-like receptors were upregulated in DLBCL samples, particularly in M0 and M1 macrophages, compared with controls. Moreover, their expression level was positively correlated with that of CD68 (a pan-macrophage marker). We confirmed the positive correlation between CD68 and IRF8 expression at the protein level in DLBCL tissue samples, where we observed increased infiltration of CD68- and IRF8-positive cells compared with normal lymph nodes. Altogether, our results highlight the inflammatory status of the DLBCL microenvironment orchestrated by macrophages. More work is needed to understand the complexity and potential therapeutic implications of inflammasomes in DLBCL.

Abstract
Cardiovascular and metabolic diseases (CVMDs) are a leading cause of death worldwide and impose a major socioeconomic burden on individuals and healthcare systems, underscoring the urgent need to develop new drug therapies. Developmental endothelial locus-1 (DEL-1) is a secreted multifunctional domain protein that can bind to integrins and play an important role in the occurrence and development of various diseases. Recently, DEL-1 has attracted increased interest for its pharmacological role in the treatment and/or management of CVMDs. In this review, we present the current knowledge on the predictive and therapeutic role of DEL-1 in a variety of CVMDs, such as atherosclerosis, hypertension, cardiac remodeling, ischemic heart disease, obesity, and insulin resistance. Collectively, DEL-1 is a promising biomarker and therapeutic target for CVMDs.

Abstract
BACKGROUND Postoperative adhesion is a common cause of long-term morbidity after abdominal or pelvic surgery. The development of postoperative adhesion involves oxidative stress, inflammatory response, and collagen deposition mechanisms. Here, we demonstrate that mitoquinone could be useful for the treatment of postoperative adhesion. METHODS A murine adhesion model was established by induction of peritoneal ischemic buttons. Mice received different doses of mitoquinone via the tail vein. All the ischemic buttons were dissected at 1 day and 7 days after surgery to investigate the effect of mitoquinone in the early and late stage of the adhesion process, respectively. Human peritoneal mesothelial cells were treated with H2O2 to examine the potential mechanisms of mitoquinone in oxidative insult. RESULTS Postoperative adhesion scores were markedly decreased in mitoquinone-treated mice compared with the control mice. The degree of oxidative stress, inflammatory injury, and collagen deposition were also significantly reduced in the mitoquinone-treated mice. The expression of plasminogen-activating inhibitor, interleukin-1, interleukin-6, tumor necrosis factor-α, vascular endothelial growth factor, malondialdehyde, and nitric oxide was decreased, while the expression of tissue-type plasminogen activator, glutathione, superoxide dismutase, and Nrf2 was increased in the peritoneal ischemic buttons after mitoquinone treatment. Cellular reactive oxygen species and the canonical inflammatory pathway were inhibited in mitoquinone-treated human peritoneal mesothelial cells after H2O2 challenge. Mechanistically, mitoquinone was found to enhance the activity of Nrf2 and heme oxygenase-1 and to induce nuclear translocation of Nrf2 in human peritoneal mesothelial cells. CONCLUSION The mitochondria-targeting antioxidant molecule mitoquinone attenuates postoperative adhesion formation by inhibiting oxidative stress, inflammation, and collagen accumulation, and therefore provides a therapeutic agent for the management of surgical adhesion.

Abstract
Developmental endothelial locus-1 (Del-1) is a secretory, multifunctional domain protein. It can bind to integrins and phosphatidylserine. As a local tissue signal, it plays a regulatory role in the cancer microenvironment and inflammation. Del-1 has destructive effects in most cancers and is associated with the progression and invasion of some cancers. In contrast, Del-1 also plays a protective role in inflammation. Del-1 regulates inflammation by regulating the generation of neutrophils in bone marrow, inhibiting the recruitment and migration of neutrophils and accelerating the clearance of neutrophils by macrophages. Del-1 and IL-17 are reciprocally regulated, and their balance maintains immune system homeostasis. Del-1 is expected to become a new therapeutic target for inflammatory disorders such as multiple sclerosis.

Abstract
Objective This prospective study sought to clarify the developmental endothelial locus-1 (Del-1) protein as values of diagnosis and risk stratification of prostate cancer (PCa). Design From February 2017 to December 2019, a total 458 patients who underwent transrectal ultrasound guided prostate biopsy or surgery of benign prostatic hyperplasia agreed to research of Del-1 protein. We prospectively compared and analyzed the Del-1 protein and prostate specific antigen (PSA) in relation to the patients’ demographic and clinicopathological characteristics. Results Mean age was 68.86±8.55 years. Mean PSA and Del-1 protein was 21.72±89.37, 0.099±0.145, respectively. Two hundred seventy-six (60.3%) patients were diagnosed as PCa. Among them, 181 patients underwent radical prostatectomy (RP). There were significant differences in Del-1 protein between benign and PCa group (0.066±0.131 vs 0.121±0.149, respectively, p<0.001). When we set the cut-off value of del-1 protein as 0.120, in patients with 3≤PSA≤8, positive predictive value and specificity of Del-1 protein (≥0.120) for predicting PCa were 88.9% (56/63) and 93.5% (101/108), respectively. Among 181 patients who underwent RP, there were significant differences in Del-1 protein according to stage (pT2 vs pT3a vs ≥pT3b) (0.113±0.078, 0.171±0.121, 0.227±0.161, respectively, p<0.001) and to Gleason score (6 (3+3) or 7 (3+4) vs 7 (4+3) or 8 (4+4) vs 9 or 10) (0.134±0.103, 0.150±0.109, 0.212±0.178, respectively, P = 0.044). Multivariate analysis showed that PSA, Del-1 protein and high Gleason score (≥9) were the independent prognostic factors for predicting higher pT stage (≥3b). Furthermore, age, PSA and Del-1 protein were independent prognostic factors for predicting significant PCa. Conclusion Patients with PCa showed higher expression of Del-1 protein than benign patients. Del-1 protein increased with the stage and Gleason score of PCa. Collaboration with PSA, Del-1 protein can be a non-invasive useful marker for diagnosis and risk stratification of PCa.

Abstract
Intraperitoneal adhesion is a common complication after abdominal surgery, which seriously affects the quality of life of patients. HuoXueTongFu Formula (HXTF) plays an important role in the prevention and treatment of intraperitoneal adhesions. However, the molecular-related mechanisms are still not fully known. In this study, the model of Intrapetitoneal adhesion was established by cecum abrasion and treated with HXTF for one week. RAW264.7 cells were given LPS, IFN-γ, IL-4, HXTF-medicated serum, and PPAR-γ agonist/antagonist, respectively. Histopathology, flow cytometry, ELISA, real-time PCR, and Western blotting were used to further detect the related protein, M1/M2 polarization tendency, and PPAR-γ nuclear translocation. The deposition of collagen fibres reduced in the local area of rats after the operation with HXTF treatment. Similar to IL-4, HXTF induced a tendency for macrophages to polarize toward M2 and promoted peroxisome proliferator-activated receptor-gamma (PPAR-γ) nuclear translocation. Furthermore, the use of HXTF and PPAR-γ agonists downregulated macrophage M1 polarization-related factors IL-1, IL-6, and TNF-alpha and upregulated M2 polarization-related factors IL-4, IL-10, and TGF-beta 1. Meanwhile, the use of HXTF and PPAR-γ agonists downregulated the SOCS3/JAK2/STAT1 pathway and activated the SOCS1/STAT6/PPAR-γ pathway. These results show that HXTF may reduce intraperitoneal adhesion by inducing macrophage M2 polarization and regulating the SOCS/JAK2/STAT/PPAR-γ pathway.
