Abstract
Systemic sclerosis (SSc) is an autoimmune rheumatic disease with high mortality, which is featured by inflammation, vascular damage, and aggressive fibrosis. To date, the pathogenesis of SSc remains unclear and effective treatments are still under research. Active NLRP3 recruits downstream proteins such as ASC and caspase-1 and assembles into inflammasome, resulting in excretion of inflammatory cytokines including IL-1β and IL-18, as well as in pyroptosis mediated by gasdermin D. Various studies demonstrated that NLRP3 inflammasome might be involved in the mechanism of tenosynovitis, arthritis, fibrosis, and vascular damage. The pathophysiological changes might be due to the activation of proinflammatory Th2 cells, profibrotic M2 macrophages, B cells, fibroblasts, and endothelial cells. Here, we review the studies focused on NLRP3 inflammasome activation, its association with innate and adaptive immune cells, endothelium injury, and differentiation of fibroblasts in SSc. Furthermore, we summarize the prospect of therapy targeting NLRP3 pathway.

Abstract
Dioscin presents extents of pharmacological activities on several diseases, but its effect and mechanism on diabetes cognitive dysfunction (DCD) remains unclear. Herein, we conducted a series of pharmacological evaluation assays of purinergic receptor P2X7 (P2X7R) with dioscin. We uncovered that dioscin presented a clearly protective effect on diabetes cognitive dysfunction via a methylglyoxal-treated PC12 cell model and streptozocin (STZ)-induced rat models. Additionally, it found that P2X7R and NLRP3 inflammasome signals were activated in diabetes cognitive dysfunction via in vivo and in vitro detection. Moreover, it was demonstrated that P2X7R regulated NLRP3 inflammasome signals in methylglyoxal-treated PC12 cells. Meanwhile, it was showed that dioscin-induced anti-diabetes cognitive dysfunction effect was accompanied with an inhibition of P2X7R/NLRP3 signal. A deeper mechanical study indicated that an overexpression of P2X7R further enhanced the protective effect of dioscin. Whilst, an inhibition of P2X7R abolished the protective effect of dioscin. These results suggested that dioscin protected type 2 diabetes cognitive dysfunction through, at least partially, regulating the P2X7R/NLRP3 signal pathway. Our findings further indicate the great value of dioscin on preventing type 2 diabetes cognitive dysfunction.

Abstract
Macrophages participate in the pathogenesis of ankylosing spondylitis (AS) by producing inflammatory cytokines. Extracellular adenosine triphosphate (eATP), released during cell stress, acts through purinergic receptors (P2XR and P2YR) and induces inflammatory responses. We investigated the effect of 2ʹ(3ʹ)-O-(4-benzoyl benzoyl) ATP (BzATP) (a prototypic agonist of P2X7R) on the production of inflammatory cytokines in both monocyte-generated (M2-like) and M1 macrophages from patients and controls. Macrophages were differentiated from isolated periphery-monocytes (n = 14 in each group) by macrophage colony-stimulating factor (M-CSF). Using LPS and IFN-γ, macrophages were skewed toward M1 type and were treated with BzATP. Gene expression and protein release of IL-1β, IL-23, and TNF-α were evaluated by real-time PCR and ELISA methods respectively before and after treatment. BzATP significantly increased the protein release of TNF-α and the expression of TNFA and IL1B in monocyte-generated macrophages. Besides, BzATP treatment significantly upregulated IL1B expression, reduced TNFA and IL23A expression, and TNF-α release in M1 macrophages from both groups. Monocyte-generated and M1 macrophages from AS patients released higher TNF-α and expressed more IL1B in response to the same concentration of BzATP treatment respectively. Based on our results, AS macrophages were more sensitive to BzATP treatment and responded more intensively. Besides, the diverse effects of BzATP on monocyte-derived and M1 macrophages in our study may represent the differed inflammatory properties of these two groups of macrophages in response to eATP in the body.

Abstract
Fibrotic skin disorders, such as keloid disease (KD), are common clinically challenging disorders with unknown etiopathogenesis and ill-defined treatment strategies that affect millions of people worldwide. Thus, there is an urgent need to discover novel therapeutics. The validation of potential drug targets is an obligatory step in discovering and developing new therapeutic agents for the successful treatment of dermal fibrotic conditions, such as KD. The integration of multi-omics data with traditional and modern technological approaches, such as RNA interference (RNAi) and genome-editing tools, would provide unique opportunities to identify and validate novel targets in KD during early drug development. Thus, in this review, we summarize the current and emerging drug discovery process with a focus on validation strategies of potential drug targets identified in dermal fibrosis.

Abstract
P2X7R activation contributes to the pathogenesis of pulmonary hypertension. However, the molecular mechanism through which P2X7R participates in pulmonary vascular remodeling is largely unknown. The rats and pulmonary artery smooth muscle cells (PASMCs) were maintained under hypoxia. P2X7R expression was determined by real-time PCR and western blotting. The pathological changes of lung tissue were evaluated via HE staining after treatment with a P2X7R antagonist, A740003. After treatment with A740003 or silencing P2X7R, proliferating cell nuclear antigen (PCNA), phenotype markers and phospho-c-Jun N-terminal kinase (JNK)/JNK expression were tested by western blotting. P2X7R expression in hypoxia group was significantly higher than that in normoxia group in vivo and in vitro. The pathological changes of lung tissue induced by hypoxia were significantly relieved by treatment with a P2X7R antagonist, A740003. Hypoxia stimulated the proliferation and synthetic phenotype of PASMCs, which were aggravated by a P2X7R agonist treatment and alleviated by a P2X7R antagonist or silencing P2X7R mRNA treatment. Silencing P2X7R mRNA significantly decreased the hypoxia-induced upregulation of phospho-JNK/JNK in PASMCs. The phenotype switching of PASMCs in hypoxia was reversed by treatment with JNK inhibitor. The findings indicate that P2X7R may be involved in the hypoxia-induced proliferation and phenotype switching of PASMCs via JNK signaling pathway, which suggests a new therapeutic strategy targeting P2X7R in vascular remodeling of pulmonary arterial hypertension.

Abstract
Wound healing represents an urgent need from the clinical point of view. Several diseases result in wound conditions which are difficult to treat, such as in the case of diabetic foot ulcer. Starting from there, the medicinal research has focused on various targets over the years, including GPCRs as new wound healing drug targets. In line with this, GPR120, known to be an attractive target in type 2 diabetes drug discovery, was studied to finalize the development of new wound healing agents. Pinocembrin (HW0) was evaluated as a suitable compound for interacting with GPR120, and was hybridized with fatty acids, which are known endogenous GPR120 ligands, to enhance the wound healing potential and GPR120 interactions. HW0 and its 7-linolenoyl derivative (HW3) were found to be innovative wound healing agents. Immunofluorescence and functional assays suggested that their activity was mediated by GPR120, and docking simulations showed that the compounds could share the same pocket occupied by the known GPR120 agonist, TUG-891.

Abstract
Wound healing is a dynamic process required to maintain skin integrity and which relies on the precise migration of different cell types. A key molecule that regulates this process is ATP. However, the mechanisms involved in extracellular ATP management are poorly understood, particularly in the human dermis. Here, we explore the role, in human fibroblast migration during wound healing, of Pannexin 1 channels and their relationship with purinergic signals and in vivo cell surface filamentous actin dynamics. Using siRNA against Panx isoforms and different Panx1 channel inhibitors, we demonstrate in cultured human dermal fibroblasts that the absence or inhibition of Panx1 channels accelerates cell migration, increases single-cell motility, and promotes actin redistribution. These changes occur through a mechanism that involves the release of ATP to the extracellular space through a Panx1-dependent mechanism and the activation of the purinergic receptor P2X7. Together, these findings point to a pivotal role of Panx1 channels in skin fibroblast migration and suggest that these channels could be a useful pharmacological target to promote damaged skin healing.

Abstract
P2X7 receptor (P2X7R), a distinct ligand-gated ion channel, is a member of purinergic type 2 receptor family with ubiquitous expression in human body. Previous studies have revealed a pivotal role of P2X7R in innate and adaptive immunity. Once activated, it will meditate some vital cascaded responses including the assembly of nucleotide-binding domain (NOD) like receptor protein 3 (NLRP3) inflammasome, non-classical secretion of IL-1β, modulation of cytokine-independent pathways in inflammation such as P2X7R- transglutaminase-2 (TG2) and P2X7R-cathepsin pathway, activation and regulation of T cells, etc. In fact, above responses have been identified to be involved in the development of autoimmunity, specifically, the NLRP3 inflammasome could promote inflammation in massive autoimmune diseases and TG2, as well as cathepsin may contribute to joint destruction and degeneration in inflammatory arthritis. Recently, numerous evidences further suggested the significance of P2X7R in the pathogenesis of autoimmune diseases, including systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), inflammatory bowel disease (IBD), multiple sclerosis (MS), etc. In this review, we will succinctly discuss the biological characteristics and summarize the recent progress of the involvement of P2X7R in the development and pathogenesis of autoimmune diseases, as well as its clinical implications and therapeutic potential.

Abstract
Pulmonary arterial hypertension (PAH) is a progressive disease that ultimately leads to right heart failure and death. Current strategies are ineffective to prevent and cure PAH, especially in those who undergo cardiopulmonary bypass. P2 × 7 receptors (P2 × 7Rs) have been implied to participate in the pathogenesis of PAH and injuries induced by ischemia-reperfusion (IR). In the present study, we aimed to assess the potential therapeutic effects of anti-P2 × 7Rs on PAH and IR-induced lung injuries in rats and explore their underlying cellular and molecular mechanisms. In the present study, we have successfully established rat models with PAH and/or lung IR injuries. Immunohistochemical staining, western blot, and polymerase chain reaction were performed to detect the P2 × 7R expression in these models; P2 × 7R-specific inhibitor, Brilliant Blue G (BBG), was used to antagonize P2 × 7R, and enzyme-linked immunosorbent assay was used to help evaluate the P2 × 7R-mediated function in PAH with or without IR. Moreover, BBG, SB203580 (p38/MAPK inhibitor), and CD39 (adenosine triphosphate hydrolase) were applied to explore the inner signal pathway in vitro and in vivo. Our findings showed that P2 × 7R was involved in the development of PAH. By applying BBG, we have shown that the severity of PAH and IR was ameliorated through reducing the release of proinflammatory cytokines. Moreover, our results in vitro and in vivo indicated that P2 × 7R regulated the release of inflammatory mediators by the p38/MAPK signal pathway. Most important, CD39 showed the most dominant potential in improving inflammation in lung injuries caused by PAH and IR. In conclusion, the inhibition of P2 × 7R could effectively attenuate inflammation in lung injuries caused by PAH and IR in rats by reducing proinflammatory cytokines through regulating the p38/MAPK pathway.

Abstract
Ginseng is widely used in energy drinks, dietary supplements, and herbal medicines, and its pharmacological actions are related with energy metabolism. As an important modulating energy metabolism pathway, liver X receptors (LXRs) can promote the resolving of hepatic fibrosis and inflammation. The present study aims to evaluate the regulation of 25-OCH3-PPD, a ginsenoside isolated from Panax ginseng, against hepatic fibrosis and inflammation in thioacetamide (TAA)-stimulated mice by activating the LXRs pathway. 25-OCH3-PPD decreases serum ALT/AST levels and improves the histological pathology of liver in TAA-induced mice; attenuates transcripts of pro-fibrogenic markers associated with hepatic stellate cell activation; attenuates the levels of pro-Inflammatory cytokines and blocks apoptosis happened in liver; inhibits NLRP3 inflammasome by affecting P2X7R activation; and regulates PI3K/Akt and LKB1/AMPK-SIRT1. 25-OCH3-PPD also facilitates LX25Rs and FXR activities decreased by TAA stimulation. 25-OCH3-PPD also decreases α-SMA via regulation of LXRs and P2X7R-NLRP3 in vitro. Our data suggest the possibility that 25-OCH3-PPD promotes activity of LXRs to ameliorate P2X7R-mediated NLRP3 inflammasome in the development of hepatic fibrosis.
