Abstract
The breakdown of immune tolerance and the rise in autoimmunity contribute to the onset of rheumatoid arthritis (RA), driven by significant changes in immune components. Recent advances in single-cell and spatial transcriptome profiling have revealed shifts in cell distribution and composition, expanding our understanding beyond molecular-level changes in inflammatory cytokines, autoantibodies, and autoantigens in RA. Surprisingly, synovial fibroblasts (SFs) play an active immunopathogenic role rather than remaining passive bystanders in RA, with notable alterations in their subpopulation distribution and composition. This study examines these changes in SF heterogeneity, assesses their impact on RA progression, and elucidates the immune characteristics and functions of SF subsets in the RA autoimmunity, encompassing both intrinsic and adaptive immunity. Additionally, this review discusses therapeutic strategies targeting immune SF subsets, highlighting the potential of future interventions in SF phenotypic reprogramming. Overall, this review redefines the role of SFs in RA and suggests targeting SF phenotypic reprogramming and its upstream molecules as a promising therapeutic approach to restore immune balance and modulate immune tolerance in RA.

Abstract
Fungal infections are a public health problem that mainly affects immunosuppressed people, Candida spp. have been responsible for most sources of contamination and invasive fungal infections described around the world. The need arises to find new therapeutic approaches to combat growing infections. Plants and natural products have been considered a valuable source for discovering new molecules with active ingredients. Diosgenin is a sapogenin found in the families of Leguminosae and Dioscoreaceae, it is obtained mainly from the dioscin saponin through the hydrolysis method, it is a phytochemical that has been highlighted in the treatment of various diseases, as well as in combating microbial resistance. The present study aimed to evaluate the susceptibility of fungal strains to diosgenin, as well as verify the association with the reference drug and evaluate the inhibition of the virulence factor through morphological changes in the yeast state to the filamentous form of hyphae and pseudohyphae in strains of Candida albicans, Candida tropicalis and Candida krusei using the broth microdilution method and microculture technique. Antifungal assays revealed that diosgenin was not able to inhibit the growth of the tested strains. However, it was able to inhibit the fungal dimorphism of the strains evaluated, however further studies are recommended to verify its effectiveness against other virulence factors.

Abstract
Background Rheumatoid arthritis (RA) is a chronic and systemic autoimmune disease characterized by synovial inflammation and joint destruction. Despite progress in RA therapy, it remains difficult to achieve long-term remission in RA patients. Phosphodiesterase 3B (Pde3b) is a member of the phosphohydrolyase family that are involved in many signal transduction pathways. However, its role in RA is yet to be fully addressed. Methods Studies were conducted in arthritic DBA/1 mice, a suitable mouse strain for collagen-induced rheumatoid arthritis (CIA), to dissect the role of Pde3b in RA pathogenesis. Next, RNAi-based therapy with Pde3b siRNA-loaded liposomes was assessed in a CIA model. To study the mechanism involved, we investigated the effect of Pde3b knockdown on macrophage polarization and related signaling pathway. Results We demonstrated that mice with CIA exhibited upregulated Pde3b expression in macrophages. Notably, intravenous administration of liposomes loaded with Pde3b siRNA promoted the macrophage anti-inflammatory program and alleviated CIA in mice, as indicated by the reduced inflammatory response, synoviocyte infiltration, and bone and cartilage erosion. Mechanistic study revealed that depletion of Pde3b increased cAMP levels, by which it enhanced PKA-CREB-C/EBPβ pathway to transcribe the expression of anti-inflammatory program-related genes. Conclusion Our results support that Pde3b is involved in the pathogenesis of RA, and Pde3b siRNA-loaded liposomes might serve as a promising therapeutic approach against RA.

Abstract
Diosgenin (DGN) is a well-known steroidal sapogenin that is obtained from the hydrolysis of dioscin. The current research aimed to explore the anti-inflammatory and anti-arthritic potential of DGN alone and in combination with methotrexate (MTX). The in-vitro antioxidant, and anti-arthritic potential was assessed by protein denaturation and Human red blood cell membrane stabilization assays. The in-vivo anti-inflammatory effect was examined by carrageenan-induced paw edema and xylene-induced ear edema methods. The arthritis was induced in Wistar rats by inoculation of 0.1 ml Complete Freund's adjuvant in the left hind paw at day 1. The arthritic animals received MTX 1 mg/kg as standard, DGN at 5, 10, 20 mg/kg, and a combination treatment (DGN 20 mg/kg + MTX) was administered orally from 8 to 28th day while normal and disease control received normal saline. DGN at 1600 μg/ml exhibited the highest in-vitro activities in contrast to other tested concentrations. DGN at 20 mg/kg exhibited the maximum (p < 0.05-0.0001) inhibition of inflammation in carrageenan and xyleneinduced edema models. Treatment with DGN and MTX alone and in combination significantly reduced the paw diameter, body weight, arthritic index, and pain. It restored altered blood parameters and oxidative stress biomarkers in contrast to the diseased control rats. DGN profoundly (P < 0.0001) downregulated mRNA expression of TNF-α, IL-1β, NF-ĸβ, and COX-2 while upregulated IL-4 and -10 in treated rats. The combination of DGN with MTX showed the highest therapeutic efficacy than individual therapy, so it can be used as an adjunct for rheumatoid arthritis treatment.

Abstract
Synovial samples collected from 30 rheumatoid arthritis (RA) patients and 30 normal controls were used to isolate fibroblast-like synoviocytes (FLSs) and named FLS-RA and FLS-Normal, respectively. Real-time quantitative polymerase chain reaction (RT-qPCR) was utilized to detect circ_0007707 expression. Effects of circ_0007707 silencing on cell proliferation and apoptosis were evaluated using cell counting kit-8, 5-ethynyl-2'-deoxyuridine (Edu), and flow cytometry assays. Levels of pro-inflammatory factors were detected by enzyme-linked immunosorbent assay (ELISA). Increased circ_0007707 expression was observed in synovial samples from RA patients and FLS-RA cells. Functional analysis showed circ_0007707 silencing restrained cell proliferation, induced cell apoptosis, and decreased cell inflammatory response in FLS-RA cells. Mechanistic analysis revealed the sponge function of circ_0007707 on miR-27b-3p, and miR-27b-3p inhibition weakened circ_0007707 knockdown-mediated effects on FLS-RA cell proliferation, apoptosis, and inflammatory response. Circ_0007707 could mediate PDE3B expression via sponging miR-27b-3p, and PDE3B overturned miR-27b-3p mimic-mediated effects on FLS-RA cell proliferation, apoptosis, and inflammatory response. Circ_0007707 mediated cell apoptosis and inflammatory response in FLS-RA cells through the miR-27b-3p/PDE3B axis, indicating the potential function of circ_0007707 as a target for RA treatment.

Abstract
Diosgenin was the starting materials to synthesize various hormone drugs and mainly generated from Dioscorea zingiberensis C. H. Wright by acidolysis, enzymolysis, microbiological fermentation, and integrated manner. Only acidic hydrolysis with strong acid such as hydrochloric acid or sulfuric acid was used in practice in diosgenin enterprises due to their feasibility and simplicity, nevertheless finally resulting in a great deal of unmanageable wastewater and severely polluted the surrounding environment. Aiming to provide a comprehensive and up-to date information of researches on diosgenin production from this plant, 151 cases were collected from scientific databases including Web of Science, Pubmed, Science Direct, Wiley, Springer, and China Knowledge Resource Integrated (CNKI). Their advantages and disadvantages with different production methods were analyzed based on these available data in this review paper. Considering the fact that nearly all of diosgenin enterprises were closed for the environmental protection and the life health of the people, this review paper was beneficial for providing useful guidelines to develop novel technologies with environmentally-friendly and cleaner features for diosgenin production or facilitate the transformation of other methods like enzymolysis, microbiological fermentation, or integrated methods from laboratory scale to industry scale.

Abstract
As a worldwide health issue, obesity is associated with the infiltration of monocytes/macrophages into the adipose tissue causing unresolved inflammation. Monocyte chemoattractant protein-1 (MCP-1) exerts a crucial effect on obesity-related monocytes/macrophages infiltration. Clinically, aspirin and salsalate are beneficial for the treatment of metabolic diseases in which adipose tissue inflammation plays an essential role. Herein, we investigated the effect and precise mechanism of their active metabolite salicylate on TNF-α-elevated MCP-1 in adipocytes. The results indicated that salicylate sodium (SAS) could lower the level of MCP-1 in TNF-α-stimulated adipocytes, which resulted from a previously unrecognized target phosphodiesterase (PDE), 3B (PDE3B), rather than its known targets IKKβ and AMPK. The SAS directly bound to the PDE3B to inactivate it, thus elevating the intracellular cAMP level and activating PKA. Subsequently, the expression of MKP-1 was increased, which led to the decrease in p-EKR and p-p38. Both PDE3B silencing and the pharmacological inhibition of cAMP/PKA compromised the suppressive effect of SAS on MCP-1. In addition to PDE3B, the PDE3A and PDE4B activity was also inhibited by SAS. Our findings identify a previously unrecognized pathway through which SAS is capable of attenuating the inflammation of adipocytes.

Abstract
BACKGROUND It is a research hotspot to use natural compounds in treatment of cerebral ischemia reperfusion (I/R) for a refractory disease throughout the worldwide without available drugs or treatments at present. Our previous study has demonstrated that diosgenin (DIO), a starting material to synthesize various steroid anti-inflammatory drugs in medical industry, showed medicinal effect against I/R via inhibiting aberrant inflammatory reaction induced by I/R. However, the detailed anti-inflammatory network of DIO in treatment of I/R still remains to be further explored. PURPOSE HIKESHI was firstly identified as a novel target of DIO used for I/R by rat brain proteomic analysis, and mechanistic efforts were focused based on this gene. Hopefully, extensive detailed molecular mechanisms of DIO against I/R was established and confirmed. METHODS The effect of DIO against I/R was examined in vitro and in vivo, which cells (SH-SY5Y and PC12) and rats were experienced to ORD/RP and MCAO exposures, respectively, to establish I/R modes. Staining was used to evaluate the pathological procedure of DIO used for I/R. Protein changes including expression, interaction, and activity during DIO's anti-I/R effect were assessed with real time PCR, western blot, Co-IP, luciferase reporter assay. RESULTS In the current study, HIKESHI and HSP70 were both upregulated, when I/R cells and rats were treated with DIO in vitro and in vivo. Mechanistically, DIO stimulated the binding of HIKESHI to HSP70 and facilitated the translocation of HSP70 into nucleus. Subsequently, HSP70 blunted the transcription activity of NF-κB after physical interaction with this transcription factor, and therefore led to the suppression of its downstream pro-inflammatory cytokine (TNF-α, IL-1β, and IL-6) release into surrounding I/R lesion area. Conversely, HIKESHI or HSP70 knockdowns attenuated the nuclear translocation and restraint on NF-κB-mediated inflammation, finally resulting in the abolishment of DIO-induced anti-I/R effect. NF-κB activation also relieved the inhibitory inflammation and reversed DIO's effect against I/R, suggesting that NF-κB was the downstream target of HIKESHI and HSP70 in I/R treatment with DIO. CONCLUSIONS These findings established a novel HIKESHI/HSP70/NF-κB signaling pathway associated with DIO-treated I/R, which might be as therapeutic targets or drugs with potential implications for the therapeutic use of I/R in clinic.

Abstract
Diabetes mellitus is a metabolic disease caused by defective insulin secretion and/or insulin action. And insulin is the main hormone released by the pancreatic β-cells. Diosgenin (DG) is a phytochemical with pharmacological activity that increases insulin secretion in streptozotocin (STZ)-induced pancreatic β-cells of diabetic rats. In this paper, we investigated the effect and mechanism of DG on cell apoptosis and dysfunction in STZ-induced pancreatic β-cells. Cell viability was detected by CCK-8, apoptosis by flow cytometry, and apoptosis-related protein expression by Western blot. Western blot and RT-qPCR were performed to detect the expression of related genes. The results showed that in STZ-induced INS-1 cells, DG could improve cell viability, inhibit apoptosis, attenuate oxidative stress levels and increase insulin secretion. Notably, PDE3B was highly expressed in STZ-induced INS-1 cells, while DG could significantly inhibit PDE3B expression in a dose-dependent manner. More importantly, overexpression PDE3B remarkably reversed the effect of DG on STZ-induced INS-1 cells. It is thus clear that DG might inhibit STZ-treated pancreatic β-cell apoptosis and reduce dysfunction via downregulating PDE3B, which provided a more reliable theoretical basis for the treatment of diabetes mellitus with DG.
