PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 132:155762. [PMID: 38964156 DOI: 10.1016/j.phymed.2024.155762] [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: 01/22/2024] [Revised: 05/09/2024] [Accepted: 05/18/2024] [Indexed: 07/06/2024]
Abstract
BACKGROUND Rheumatoid arthritis (RA) is a chronic autoimmune disorder characterized by exacerbated synovial inflammation and joint destruction. Recent studies suggest toll-like receptor 4 (TLR4) internalization facilitate inflammatory response of macrophage. The role of TLR4 internalization in the pathogenesis of RA is unknown. PURPOSE To investigate the role and mechanism of TLR4 internalization in macrophage inflammatory response of RA and explore whether TLR4 internalization mediates the anti-arthritic effect of Xiaowugui (XWG) decoction, a patented herbal formula used in China. METHODS The co-expression of TLR4 and the internalization marker, early endosome antigen 1 (EEA1), in the synovial samples of RA patients and joint tissue of collagen-induced arthritis (CIA) mice, were evaluated using immunofluorescence. The effect of Rab5a-mediated early internalization of TLR4 on the activation induced by lipopolysaccharide (LPS) in RAW264.7 cells was investigated using small interfering RNAs that act against Rab5a. CIA was induced in Rab5a-/- mice to evaluate the role of Rab5a in vivo. The disease progression and expression of Rab5a and TLR4 in the joint tissue were evaluated in CIA mice treated with XWG. Inflammatory factors production, TLR4 internalization, and activation of downstream signaling pathways were examined in RAW264.7 cells treated with XWG in vitro. RESULTS The co-expression and co-localization of TLR4 and EEA1 were elevated in the synovial samples of RA patients and joint tissue of CIA mice. Pharmaceutical inhibition of TLR4 internalization reduced macrophages inflammatory responses induced by LPS. The co-expression and co-localization of Rab5a and TLR4 were significantly increased in macrophages treated with LPS. Silencing Rab5a reduced LPS-induced TLR4 internalization, inflammatory factors production, and phosphorylation of Jun N-terminal kinases (JNK) and p65. Genetic deletion of Rab5a inhibited TLR4 internalization and the development of arthritis in vivo. The co-expression of TLR4 and Rab5a was also elevated in the synovial samples of RA patients. XWG treatment of mice with CIA alleviated arthritis and reduced the co-expression of Rab5a and TLR4 in the joint tissue. XWG treatment of macrophage inhibited LPS-induced IL-6 and TNF-α production, co-expression of Rab5a and TLR4, and phosphorylation of JNK and p65. CONCLUSIONS Our findings highlight the pathogenic role of TLR4 internalization in patients with RA and identify a novel Rab5a-dependent internalization pathway that promotes macrophage inflammatory response. XWG treatment demonstrated outstanding therapeutic effects in experimental arthritis, and targeting the Rab5a-mediated internalization of TLR4 may be the main underlying mechanism.

Int Immunopharmacol 2023; 123:110804. [PMID: 37595490 DOI: 10.1016/j.intimp.2023.110804] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Revised: 08/09/2023] [Accepted: 08/11/2023] [Indexed: 08/20/2023]
Abstract
BACKGROUND Rheumatoid arthritis (RA) is a chronic autoimmune disease characterised by progressive articular damage, functional loss, and comorbidities. The relationship between cuproptosis, a form of programmed cell death, and RA remains unknown. Therefore, this study aimed to explore cuproptosis-related molecular clusters in RA. METHODS Gene expression profiles of GSE93272 were downloaded from the Gene Expression Omnibus to identify the expression profiles of cuproptosis regulators and the immune infiltration characteristics of RA. The molecular clusters of cuproptosis-related genes and the related immune cell infiltration were explored. Cluster-specific differentially expressed genes were identified using the weighted gene co-expression network analysis. Further, an external dataset (GSE15573) was used, and an enzyme-linked immunosorbent assay was performed to validate the predictive efficiency. RESULTS Thirteen cuproptosis-related genes and activated immune responses were identified between patients with RA and controls. Immune infiltration revealed significant immunological heterogeneity in the two cuproptosis-related molecular clusters in RA. Functional enrichment indicated that Cluster1 and Cluster2 were predominantly enriched in the toll-like receptor signalling pathway and regulation of autophagy, respectively. Further, the performance of FAM96A and CGRRF1 genes in the external validation dataset was observed to be relatively satisfactory (area under the receiver operating characteristic curve = 0.687 and 0.674, respectively). Based on our serum samples, FAM96A and CGRRF1 both exhibited higher expression levels in patients with RA (p = 0.001; p = 0.000). CONCLUSIONS Our study systematically illustrated the involvement of cuproptosis in the progression of RA, and explored the pathogenic mechanisms and novel therapeutic strategies for RA, targeting FAM96A and CGRRF1.

PriPath: identifying dysregulated pathways from differential gene expression via grouping, scoring, and modeling with an embedded feature selection approach. BMC Bioinformatics 2023; 24:60.

Abstract
BACKGROUND Cell homeostasis relies on the concerted actions of genes, and dysregulated genes can lead to diseases. In living organisms, genes or their products do not act alone but within networks. Subsets of these networks can be viewed as modules that provide specific functionality to an organism. The Kyoto encyclopedia of genes and genomes (KEGG) systematically analyzes gene functions, proteins, and molecules and combines them into pathways. Measurements of gene expression (e.g., RNA-seq data) can be mapped to KEGG pathways to determine which modules are affected or dysregulated in the disease. However, genes acting in multiple pathways and other inherent issues complicate such analyses. Many current approaches may only employ gene expression data and need to pay more attention to some of the existing knowledge stored in KEGG pathways for detecting dysregulated pathways. New methods that consider more precompiled information are required for a more holistic association between gene expression and diseases. RESULTS PriPath is a novel approach that transfers the generic process of grouping and scoring, followed by modeling to analyze gene expression with KEGG pathways. In PriPath, KEGG pathways are utilized as the grouping function as part of a machine learning algorithm for selecting the most significant KEGG pathways. A machine learning model is trained to differentiate between diseases and controls using those groups. We have tested PriPath on 13 gene expression datasets of various cancers and other diseases. Our proposed approach successfully assigned biologically and clinically relevant KEGG terms to the samples based on the differentially expressed genes. We have comparatively evaluated the performance of PriPath against other tools, which are similar in their merit. For each dataset, we manually confirmed the top results of PriPath in the literature and found that most predictions can be supported by previous experimental research. CONCLUSIONS PriPath can thus aid in determining dysregulated pathways, which applies to medical diagnostics. In the future, we aim to advance this approach so that it can perform patient stratification based on gene expression and identify druggable targets. Thereby, we cover two aspects of precision medicine.

Abstract
OBJECTIVE Rheumatoid arthritis (RA) is mainly characterized by synovial hyperplasia, angiogenesis, inflammatory cells infiltration. Chymotrypsin is a proteolytic enzyme with anti-inflammatory effects. The current project was intended to test the efficacy and mechanism of chymotrypsin in adjuvant-induced arthritis (AIA) rats to provide an experimental basis for the clinical application of chymotrypsin. METHODS Sprague-Dawley rats were injected with complete Freund's adjuvant (CFA) in the hind left paw pad to establish an AIA model. Forty rats were randomly divided into five groups (n = 8): blank; CFA model (model); low-dose chymotrypsin (CLD), 0.53 mg/kg; high-dose chymotrypsin (CHD), 1.06 mg/kg; piroxicam, 10 mg/kg. The treatments were performed in the subplantar region of the left hind paw from Day 8 (D8) to Day 28 after adjuvant injection. The body weight, paw diameter, swelling degree of paw, and arthritic score were measured on D0, D7, D14, D21, and D28. All animals were sacrificed on D29. Subsequently, the synovial tissue of the ankle joint of the rats was stained with HE to generate pathological sections for observation of the pathological changes of synovial tissue from the ankle joint. The protein levels of MMP-1, TNF-α, IL-1β, and IL-6 in the rats' serum were determined by ELISA. Western blotting was used to detect the protein expression of TLR4 and NF-κB in the rat ankle tissue. The mRNA expression of TLR4, NF-κB, IL-1β, IL-6, and TNF-α in synovial tissue of the ankle joint was detected by RT-qPCR. RESULTS The body weight of the rats in each group showed an increasing trend, and there was no significant difference in weight between the groups. CHD and piroxicam suppressed paw swelling and arthritic scores and decreased synovial hyperplasia, inflammatory cell infiltration, pannus formation, and bone destruction. Furthermore, the overproduction of MMP-1, TNF-α, IL-1β, and IL-6 in serum was remarkably attenuated in the chymotrypsin- and piroxicam-treated rats. The protein levels of TLR4 and NF-κB in the synovial tissue of the chymotrypsin group and the piroxicam group were significantly lower than those in the model group. Likewise, the rats treated with chymotrypsin and piroxicam had a substantial decline in the mRNA expression of TLR4, NF-κB, TNF-α, IL-1β, and IL-6 in synovial tissue. CONCLUSIONS Chymotrypsin alleviates the joint damage of AIA rats, probably by reducing the expression of MMP-1, TNF-α, IL-1β, and IL-6 through TLR4/NF-κB signaling pathway.

Abstract
CD4+ T cells mediate rheumatoid arthritis (RA) pathogenesis through both antibody-dependent and independent mechanisms. It remains unclear how synovial microenvironment impinges on CD4+ T cells pathogenic functions. Here, we identified a TLR4+ follicular helper T (Tfh) cell-like population present in the blood and expanded in synovial fluid. TLR4+ T cells possess a two-pronged pathogenic activity whereby direct TLR4+ engagement by endogenous ligands in the arthritic joint reprograms them from an IL-21 response, known to sponsor antibody production towards an IL-17 inflammatory program recognized to fuel tissue damage. Ex vivo, synovial fluid TLR4+ T cells produced IL-17, but not IL-21. Blocking TLR4 signaling with a specific inhibitor impaired IL-17 production in response to synovial fluid recognition. Mechanistically, we unveiled that T-cell HLA-DR regulates their TLR4 expression. TLR4+ T cells appear to uniquely reconcile an ability to promote systemic antibody production with a local synovial driven tissue damage program. In order to identify how the synovial microenvironment impinges on CD4+ T cells pathogenic functions in Rheumatoid Arthritis (RA), Amaral-Silva examined RA patient blood and synovial fluif and identified the presence of a TLR4+ follicular helper T (Tfh) cell-like population. They provided mechanistic insight into how TLR4+ T cells uniquely reconcile an ability to promote systemic antibody production with a local synovial driven-tissue damage program.

Abstract
Low back pain is a common clinical problem that causes disability and impaired quality of life. While the reason behind low back pain was largely considered to be of musculoskeletal origin, the contribution of inflammatory cytokines and oxidative stress could never be overlooked. Exercise has been proven to be an effective approach to treat low back pain. However, the mechanism of the exercise effect on the inflammatory cytokines and oxidative stress is still largely unknown. In this study, we revealed that exercise intervention reduces Toll-like receptor 4 (TLR-4) pathway and enhances Sirtuin 1 (SIRT1) expression in low back pain patients. We also confirmed that exercise up-regulates the expression of peroxisome proliferator-activated receptor-gamma, PPAR-γ coactivator-1 and FoxOs family proteins and also increases the activity of catalase and superoxide dismutase in patients with low back pain. Furthermore, we found that exercise intervention attenuates the oxidative stress, pro-inflammatory cytokine concentrations and p53 expression in patients with low back pain. This study demonstrates that exercise intervention improves low back pain symptoms through regulation of the SIRT1 axis with repression of oxidative stress and TLR-4 inhibition.
