Sulforaphane inhibits cytokine-stimulated chemokine and adhesion molecule expressions in human corneal fibroblasts: Involvement of the MAPK, STAT, and NF-κB signaling pathways. Exp Eye Res 2022; 216:108946. [PMID: 35038457 DOI: 10.1016/j.exer.2022.108946] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2021] [Revised: 12/28/2021] [Accepted: 01/07/2022] [Indexed: 11/17/2022]
Abstract
Chemokines and adhesion molecules are major inflammatory mediators of chronic and recurrent vernal keratoconjunctivitis (VKC). Sulforaphane (SFN) is a natural plant extract that is known to have anti-inflammatory and antioxidant properties. SFN is demonstrated to be effective against a variety of human diseases. The current investigation examines the effects and the molecular mechanisms of SFN on cytokine-induced human corneal fibroblasts (HCFs) expression of adhesion molecules and chemokines. HCFs were exposed to both interleukin (IL)-4 and tumor necrosis factor (TNF)-α in the absence or presence of SFN treatment. The levels of thymus- and activation-regulated chemokine (TARC) and eotaxin-1 in culture supernatants were evaluated using enzyme-linked immunosorbent assay (ELISA). Reverse transcription-polymerase chain reaction analysis (RT-PCR) enabled quantification of mRNA levels of vascular cell adhesion molecule (VCAM)-1, eotaxin-1, and TARC along with cytokine receptors. An immunoblotting assay was used to evaluate the activities of VCAM-1, nuclear factor-kappa B (NF-κB), mitogen-activated protein kinases (MAPKs), signal transducer and activator of transcription factor (STAT)6 pathways, along with the expression of the cytokine receptors including IL-4 receptor (R)α, IL-13Rα1, TNFRI, as well as TNFRII. SFN inhibited TARC and eotaxin-1 release in HCFs stimulated by TNF-α and IL-4 in a manner dependent on dose and time. SFN suppressed transcriptions of TARC, eotaxin-1, and VCAM-1. Furthermore, the mRNA and protein expression levels of IL-4Rα, TNFRI, and TNFRII were also attenuated by SFN exposure, however, those of IL-13Rα1 remained unaffected. In addition, SFN downregulated the expression of VCAM-1 and the phosphorylation of MAPKs, IκBα, and STAT6. These results suggest that SFN inhibited cytokine-stimulated TARC, eotaxin-1 secretion as well as VCAM-1 expression in HCFs, with these effects likely occurring as a result of cytokine receptor inhibition and attenuation of MAPK, NF-κB, and STAT6 signaling. SFN may therefore have therapeutic potential in VKC treatment.

Front Med (Lausanne) 2021; 8:683506.

Abstract
Bromodomain-containing protein 4 (BRD4) has been implicated to play a regulatory role in fibrogenic gene expression in animal models of liver fibrosis. The potential role of BRD4 in liver fibrosis in humans remains unclear. We sought to investigate the expression and cellular localization of BRD4 in fibrotic liver tissues. Human liver tissues were collected from healthy individuals and patients with liver fibrosis of various etiologies. RNA-seq showed that hepatic BRD4 mRNA was elevated in patients with liver fibrosis compared with that in healthy controls. Subsequent multiple manipulations such as western blotting, real-time quantitative polymerase chain reaction, and dual immunofluorescence analysis confirmed the abnormal elevation of the BRD4 expression in liver fibrosis of various etiologies compared to healthy controls. BRD4 expression was positively correlated with the severity of liver fibrosis, and also correlated with the serum levels of aspartate aminotransferase and total bilirubin. Moreover, the expression of C-X-C motif chemokine ligand 6 (CXCL6), a factor interplayed with BRD4, was increased in hepatic tissues of the patients with liver fibrosis. Its expression level was positively correlated with BRD4 level. BRD4 is up-regulated in liver fibrosis, regardless of etiology, and its increased expression is positively correlated with higher degrees of liver fibrosis. Our data indicate that BRD4 play a critical role in the progress of liver fibrosis, and it holds promise as a potential target for intervention of liver fibrosis.

Abstract
Objective We examined the production of prostaglandin E2 (PGE2), which is the key prostaglandin involved in inflammatory disorders of the ocular surface. Tears and conjunctival fibroblasts were evaluated in order to assess allergic inflammation and the effect of specific drugs. Methods and analysis PGE2 was measured in tears from both patients and normal volunteers. Primary cultures of human conjunctival fibroblasts were incubated with interleukin (IL)-4 and tumour necrosis factor (TNF)-α with or without ketotifen fumarate or dexamethasone. The culture supernatants were removed 24 hours after exposure and the concentrations of PGE2 were quantified by ELISA. Results Significantly higher levels of PGE2 were observed in the tears of patients with severe allergic conjunctivitis than in those with post-surgical inflammation (p=0.02), and this production was reduced by eye drops. Stimulation with IL-4 and TNF-α induced the generation of PGE2 in supernatants of conjunctival fibroblasts, and this production was significantly downregulated by ketotifen fumarate or steroids. Conclusion PGE2 may participate in the pathogenesis of severe ocular allergic disease, and both ketotifen fumarate and steroid reduce the production of PGE2.

Abstract
This study evaluated the effects of Gelam honey (GH) on ex vivo corneal fibroblast ulcer model via wound healing assay, gene expression and immunocytochemistry. Corneal fibroblasts from New Zealand white rabbits were culture expanded. The corneal fibroblast wound healing capacity was observed by creating a circular wound onto confluent monolayer cells cultured in basal medium (BM), BM with GH, serum-enriched basal medium (BMS) and BMS with GH respectively. Wound healing assay and phenotypic characterization of the corneal fibroblast were performed at different stages of wound closure. Expression of aldehyde dehydrogenase (ALDH), vimentin, α-smooth muscle actin (α-SMA), lumican, collagen I and matrix metalloproteinase 12 (MMP 12) were measured at day 1, day 3 and complete wound closure day. Corneal fibroblast cultured in BMS with GH demonstrated the fastest wound closure, at day 5 post wounding. The gene expressions of ALDH and vimentin were higher than control groups while α-SMA expression was lower, in GH enriched media. The expressions of lumican, collagen I and MMP 12 were also higher in cells cultured in GH enriched media compared to the control groups. GH was shown to promote in vitro corneal fibroblast wound healing and may be a potential natural adjunct in the treatment of corneal wound.

Abstract
PURPOSE Cornea acts as a structural barrier and protects the eye from environmental stresses. Inflammation in ocular surface causes discomfort and visual distortion. Defective autophagy has been associated with inflammation and ocular surface diseases. Therefore, we explored the protective role of trehalose on inflammation and desiccation-triggered stress in human corneal cells in vitro and in dry eye patients. METHOD TNF-α and desiccation stress induced human corneal cells (piHCF and HCE-T) with or without trehalose treatment were analyzed for the expression levels of inflammatory and autophagy related markers by qPCR, western blotting, multiplex ELISA and fluorescence imaging. Dry eye patients (N = 9) were enrolled and administered with trehalose in one eye and carboxymethylcellulose (CMC) in the contralateral eye (B.I.D, for 30 days). Dry eye signs OSDI, TBUT, Schirmer's Test, and tear cytokines were measured in dry eye patient's pre and post treatment. RESULTS Cells treated with trehalose exhibits increased levels of autophagy markers LC3II and LAMP1 compared to untreated cells. Trehalose reduced the mRNA and secreted cytokines levels of IL-6, IL-8 and MCP-1 in corneal cells under TNF-α and desiccation stress mediated inflammation compared to controls. Further, trehalose reduced stress driven p38 phosphorylation in corneal cells. Additionally, topical administration of trehalose alleviated the clinical symptoms and tears cytokine levels in dry eye patients compared to CMC. CONCLUSION Trehalose reduces stress induced inflammation through p38MAPK inhibition and autophagy activation. The anti-inflammatory mechanism of trehalose was independent to NFκB pathway. Further, topical administration of trehalose ameliorated dry eye associated symptoms and associated tear cytokines levels.

Abstract
Purpose: We assessed the production of chemokines by human conjunctival fibroblasts in response to inflammation and the effects of omega (ω)-3 fatty acids on chemokine expression.Methods: Primary cultures of human conjunctival fibroblasts were incubated with interleukin-4 (IL-4) and tumor necrosis factor-alpha (TNF-α). The expression of eotaxin-1 and RANTES in response to pretreatment with docosahexaenoic acid (DHA) was investigated. Moreover, western blotting was used to evaluate the effects of DHA on the activation of nuclear factor (NF)-κB and signal transducer and activator of transcription 6 (STAT6).Results: The expression of eotaxin-1 mRNA was significantly suppressed by pretreatment with DHA with IL-4 and TNF-α costimulation. RANTES expression was similarly suppressed, but the difference was not significant. The secretion of eotaxin-1 and RANTES was significantly lower in DHA-pretreated cells than in vehicle-treated cells. Western blotting for NF-κB and STAT6 showed that these proteins were downregulated in the DHA pretreatment group compared with those in the vehicle control group.Conclusion: The results of this study suggested that DHA could have applications in the management of allergic inflammation.

Abstract
Allergic conjunctivitis (AC) is one of the most common ophthalmological disorders seen in clinical practice. Growing evidence from recent years suggests that a subset of IL-10-expressing B cells is involved in inflammatory allergic diseases. In this study, we aimed to evaluate the potential involvement of blood Bregs cells in perennial allergic conjunctivitis (PAC), and interleukins (IL)-1β, IL-6, IL-8, IL-10, and IL-12, and tumor necrosis factor (TNF)-α, were measured in tear samples and compared with healthy controls (HC) using flow cytometry. Non-significant differences in CD19+IL-10+ cell frequency between PAC patients and healthy controls (HC) were observed. Nevertheless, when we analyzed the mean fluorescence intensity (MFI) of IL-10 on CD19+CD38Lo/Med/Hi-gated cells, we observed a significant decrease in MFI in all Bregs subsets in PAC patients. Additionally, tear cytokines showed 2.8 times lower levels of IL-10 than TNF-α in PAC patients when compared to HC. Our findings demonstrate an immunological dysregulation in patients with allergic conjunctivitis, characterized by the low expression of IL-10 in circulating CD19+CD38+ Bregs subsets and an inverted tear IL-10/TNF-α ratio, promoting a local pro-inflammatory microenvironment. These findings highlight the novel pathologic changes involved in ocular allergic diseases. Understanding systemic and local mechanisms will aid the design of immunomodulating therapeutics at different levels.

Abstract
Dry eye disease (DED) is the most common ocular disease and affects millions of individuals worldwide. DED encompasses a heterogeneous group of diseases that can be generally divided into two forms including aqueous-deficient and evaporative DED. Evidence suggests that these conditions arise from either failure of lacrimal gland secretion or low tear film quality. In its secondary form, DED is often associated with autoimmune diseases such as Sjögren's syndrome and rheumatoid arthritis. Current treatment strategies for DED are limited to anti-inflammatory medications that target the immune system as the source of deleterious inflammation and tissue injury. However, there is a lack of understanding of the underlying pathogenesis of DED, and subsequently, there are very few effective treatment strategies. The gap in our knowledge of the etiology of primary DED is in part because the majority of research in DED focused on secondary autoimmune causes. This review focuses on what is currently understood about the contribution of innate and adaptive immune cell populations in the pathogenesis of DED and highlights the need to continue investigating the central role of immunity driving DED.

Abstract
Modulating conjunctival wound healing has the potential to improve outcomes after glaucoma filtration surgery and for several ocular disorders, including ocular cicatrial pemphigoid, vernal keratoconjunctivitis, and pterygium. Although anti-inflammatories and antimetabolites have been used with success, these nonspecific agents are not without their complications. The search for novel and more targeted means to control conjunctival fibrosis without such limitations has brought much attention to the regulation of fibroblast proliferation, differentiation, extracellular matrix production, and apoptosis. This review provides an update on where we stand with current antifibrotic agents and outlines the strategies that novel agents use, as they evolve from the bench to the bedside.

Abstract
Purpose To evaluate the postoperative changes in blebs and levels of aqueous monocyte chemotactic protein-1 (MCP-1) after trabeculectomy vs. Ex-PRESS tube shunt surgery. Methods Rabbits were subjected to trabeculectomy or Ex-PRESS tube shunt surgery and observed for up to 3 months. Intraocular pressure (IOP) was measured using a rebound tonometer. The MCP-1 level was measured by enzyme-linked immunosorbent assay (ELISA). Bleb morphology was evaluated using photos and anterior-segment optical coherence tomography (OCT). Results There were no differences in bleb appearance or IOP at any time between the groups. Bleb wall density in the anterior-segment OCT image was significantly lower 1 week after surgery in the Ex-PRESS group than the trabeculectomy group. The MCP-1 level in control eyes was 304.1 ± 45.2 pg/mL. In the trabeculectomy group, the mean aqueous MCP-1 level was 1444.9, 1914.3, 1899.8, 516.4, 398.3, 427.3, 609.5, 1612.7, 386.2, and 167.9 pg/mL at 3, 6, and 12 h, and 1, 2, 5, 7, 14, 30, and 90 days after surgery, respectively. In the Ex-PRESS group, the corresponding values were 1744.0, 1372.0, 932.5, 711.7, 396.1, 487.3, 799.5, 1327.9, 293.6, and 184.0 pg/mL. There were no significant differences in the aqueous MCP-1 level between the groups at any time point. Conclusion The postoperative changes were similar in the Ex-PRESS and trabeculectomy groups, except for bleb wall density in the anterior-segment OCT image. The postoperative aqueous MCP-1 level had bimodal peaks in both groups.

Abstract
Chemokines regulate the migration of hemopoietic cells and play an important role in the pathogenesis of many immune-mediated diseases. Intradermal recruitment of CD8(+) T cells by CXCL10 is a central feature of the pathogenesis of cutaneous acute GVHD (aGVHD), but very little is known about the pathogenesis of chronic GVHD (cGVHD). Serum concentrations of the 3 CXCR3-binding chemokines, CXCL9, CXCL10, and CXCL11, were found to be markedly increased in patients with active cGVHD of the skin (n = 8). An 80% decrease in CD4(+) cells expressing CXCR3 was seen in the blood of these patients (n = 5), whereas CD4(+) cells were increased in tissue biopsies and were clustered around the central arterioles of the dermis. The well-documented increase in expression of CXCL10 in aGVHD therefore diversifies in cGVHD to include additional members of the CXCR3-binding family and leads to preferential recruitment of CD4(+) T cells. These observations reveal a central role for chemokine-mediated recruitment of CXCR3(+) T cells in cGVHD.

Allergol Int 2011; 60:355-63. [PMID: 21502805 DOI: 10.2332/allergolint.10-oa-0247] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2010] [Accepted: 12/21/2010] [Indexed: 01/29/2023] Open
Abstract
BACKGROUND Common features of allergic or atopic ocular and skin diseases are the participation of Th2 lymphocytes and eosinophils and colonization by Staphylococcus aureus. To examine the role of interaction between Th2 cells and bacterial infection in tissue eosinophilia, we determined the effects of Th2 cytokines and peptidoglycan derived from the cell wall of S. aureus on corneal fibroblasts. METHODS Chemokine concentrations and the cell surface expression of adhesion molecules were determined by ELISAs, and chemokine and adhesion molecule mRNAs were quantitated by real-time PCR analysis. Signaling by the transcription factor NF-κB was evaluated by immunoblot and immunofluorescence analyses as well as by assay of DNA binding activity. RESULTS Among Th2 cytokines tested, only interleukin (IL)-4 and IL-13 induced a low level of eotaxin release by corneal fibroblasts, as did peptidoglycan. However, the combination of peptidoglycan and either IL-4 or IL-13 induced a marked synergistic increase both in eotaxin release (without affecting that of IL-8) and in the abundance of eotaxin mRNA. The combination of peptidoglycan and IL-4 or IL-13 also synergistically increased the surface expression of VCAM-1, but not that of ICAM-1. Peptidoglycan activated NF-κB in corneal fibroblasts, and inhibitors of NF-κB attenuated eotaxin release induced by peptidoglycan alone or in combination with IL-4 or IL-13. CONCLUSIONS Interaction of innate and adaptive immunity, as manifested by synergistic stimulation of eotaxin and VCAM-1 expression in corneal fibroblasts by peptidoglycan and Th2 cytokines, may play an important role in tissue eosinophilia associated with ocular allergy.

Allergol Int 2010; 59:309-312.

Abstract
BACKGROUND Atopic and vernal keratoconjunctivitis are severe types of ocular allergic disease characterized not only by conjunctival inflammation but also by corneal involvement. In vitro studies have suggested that breakdown of corneal epithelial barrier function and subsequent activation of stromal fibroblasts may amplify ocular allergic inflammation. CASE SUMMARY A 27-year-old man with atopic dermatitis developed atopic keratoconjunctivitis including corneal ulcer with plaque deposition in his right eye. Conjunctival inflammation in the right eye was resistant to topical steroid therapy. Surgical removal of corneal plaque and administration of autologous fibronectin eyedrops resulted not only in resurfacing of the corneal epithelium but also in amelioration of conjunctival inflammation. DISCUSSION This case suggests that loss of corneal epithelial integrity likely exacerbates conjunctival allergic inflammation and that restoration or maintenance of the barrier function of the corneal epithelium may be one of the important targets for the treatment of severe ocular allergic diseases.
