Oral Administration of Vitamin D3 Prevents Corneal Damage in a Knock-Out Mouse Model of Sjögren's Syndrome. Biomedicines 2023; 11:biomedicines11020616. [PMID: 36831152 PMCID: PMC9953695 DOI: 10.3390/biomedicines11020616] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Revised: 02/14/2023] [Accepted: 02/16/2023] [Indexed: 02/22/2023] Open
Abstract
BACKGROUND Vitamin D deficiency has been associated with dry eye development during Sjögren's syndrome (SS). Here, we investigated whether repeated oral vitamin D3 supplementation could prevent the corneal epithelium damage in an SS mouse model. METHODS 30 female mouse knock-out for the thrombospondin 1 gene were randomized (six per group) in untreated mice euthanized at 6 weeks as negative control (C-) or at 12 weeks as the positive control for dry eye (C+). Other mice were sacrificed after 6 weeks of oral vitamin D3 supplementation in the drinking water (1000, 8000, and 20,000 IU/kg/week, respectively). RESULTS The C+ mice showed alterations in their corneal epithelial morphologies and thicknesses (p < 0.01 vs. C-), while the mice receiving 8000 (M) and 20,000 (H) IU/kg/week of vitamin D3 showed preservation of the corneal epithelium morphology and thickness (p < 0.01 vs. C+). Moreover, while the C+ mice exhibited high levels and activity of corneal tumor necrosis factor alpha converting enzyme (TACE), neovascularization and fibrosis markers; these were all reduced in the M and H mice. CONCLUSIONS Oral vitamin D3 supplementation appeared to counteract the negative effect of TACE on corneal epithelium in a mouse model of SS-associated dry eye.

Abstract
Corneal alkali burns are a major ophthalmic emergency, as current therapeutic treatments are limited. Novel treatment targets and new potential agents are required to combat this severe ocular injury. Glycyrrhizin and rebamipide (RBM) are both FDA-approved drugs with potential effects against corneal alkali burns, but RBM is limited by its low aqueous solubility and low bioavailability. This study aimed to utilize dipotassium glycyrrhizinate (DG, a dipotassium salt of glycyrrhizin) as a nanocarrier encapsulating RBM to formulate an ophthalmic solution (marked DG-RBM) with strengthened activities to treat corneal alkali burns. Results showed that an easy DG-RBM preparative process generated particles with high encapsulation efficacy and ultra-small micellar size. The solubility of RBM in DG-RBM in aqueous solution was 3.1 × 105-fold enhanced than its free solution. DG-RBM exhibited excellent storage stability. In vitro cytotoxicity, ex vivo conjunctival responses, and rabbit eye tolerance tests showed that DG-RBM possessed good ocular safety profiles. DG-RBM exhibited improved in vivo corneal permeation profiles and demonstrated a strong effect against H2O2-induced oxidative damage, with a significant effect on promoting epithelial wound healing in corneal cells in vitro. As expected, in a mouse model of corneal alkali burns, the topical administration of DG-RBM achieved a strengthened efficacy against alkali burn damages. The mechanism of this therapeutic effect involved regulating high-mobility group box 1 (HMGB1) signaling and its related angiogenic and proinflammatory cytokines. These findings demonstrate the ease of preparing DG-RBM and its great potential as a novel ocular topical formulation to treat corneal alkali burns by regulating HMGB1 signaling.

Abstract
BACKGROUND Wound healing disorders characterised by impaired or delayed reepithelialisation are a serious medical problem. In the present study, we show that gold-based blood serum therapy is a suitable therapeutic approach and shows a supportive effect in wound closure of human corneal epithelial cells (HCE) in primary in vitro experiments. METHODS For this purpose, blood from healthy individuals was incubated without (S.Ctrl) or with gold-microparticles (S.Therapy) for 24 h. Prior to human epithelial cell stimulation (HCE), the gold particles were removed and the serum was diluted in DMEM (10 % or 30 %). Both groups of serum were compared after injury. HCE were cultured and injured (corneal in vitro wound model) and then stimulated with S.Ctrl or S. THERAPY RESULTS Treatment with serum from a gold-based serum therapy (S.Therapy) shows a supportive effect on wound healing in HCE cells in vitro. In addition, gold therapy supports the secretion of important cytokines normally associated with ocular surface wound healing (IL-1β, IL-6, TNF-α and TGF-β) in HCE cells. CONCLUSIONS Therapy with gold-based blood serum significantly promotes the secretion and expression of cytokines and growth factors in HCE cells in vitro. Further preclinical experiments are necessary to demonstrate the influence of this therapy on HCE cells for possible clinical application on the human ocular surface and to prove its function also in poorly healing corneal lesions.

Abstract
We evaluated the role of NLR family pyrin domain containing 3 (NLRP3) inflammasome in sterile corneal inflammation caused by lipopolysaccharide (LPS) or alkali burns in C57BL6 mice or NLRP3 KO (Nlrp3−/−) mice. Various molecules related to the NLRP3 inflammasome were upregulated in C57BL6 mice after both alkali burn injury and LPS treatment. After alkali burn injury, the corneal opacity grade was significantly reduced in Nlrp3−/− mice compared with C57BL6 mice. In Nlrp3−/− mice, Gr-1 immunoreactivity and MMP-9 mRNA expression in the corneal stroma were significantly reduced by both LPS treatment and alkali burn injury. Quantitative PCR and immunohistochemistry revealed that IL-1β and MMP-9 expression in the corneal stroma were down-regulated in Nlrp3−/− mice with both alkali burn injury and LPS treatment. These findings suggest that the NLRP3 inflammasome has a pro-inflammatory effect in the cornea by recruiting neutrophils to sites of inflammation.

Abstract
Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare, but potentially blinding diseases that affect the skin and mucous membranes. Although the cutaneous manifestations tend to be self-limited and resolve without sequelae, the chronic ocular complications associated with SJS/TEN can persist despite local therapy. Poor understanding of the underlying pathophysiology and lack of a standardized clinical approach have resulted in a paucity of data in regards to suitable treatment options. Inflammatory cellular infiltration and elevated levels of ocular surface cytokines in the conjunctival specimens of affected patients give credence to an underlying immunogenic etiology. Furthermore, the presence of ongoing ocular surface inflammation and progressive conjunctival fibrosis in the absence of exogenous aggravating factors suggest a possible role for systemic immunomodulatory therapy (IMT). We review in detail the proposed immunogenesis underlying chronic ocular SJS/TEN and the possible utility of systemic IMT.

Abstract
PURPOSE Sulfur mustard, nitrogen mustard (NM), and 2-chloroethyl ethyl sulfide all cause corneal injury with epithelial-stromal separation, differing only by degree. Injury can resolve in a few weeks or develop into chronic corneal problems. These vesicants induce microbullae at the epithelial-stromal junction, which is partially caused by cleavage of transmembranous hemidesmosomal collagen XVII, a component anchoring the epithelium to the stroma. ADAM17 is an enzyme involved in wound healing and is able to cleave collagen XVII. The activity of ADAM17 was inhibited in vesicant-exposed corneas by four different hydroxamates, to evaluate their therapeutic potential when applied 2 hours after exposure, thereby allowing ADAM17 to perform its early steps in wound healing. METHODS Rabbit corneal organ cultures exposed to NM for 2 hours were washed, then incubated at 37°C for 22 hours, with or without one of the four hydroxamates (dose range, 0.3-100 nmol in 20 μL, applied four times). Corneas were analyzed by light and immunofluorescence microscopy, and ADAM17 activity assays. RESULTS Nitrogen mustard-induced corneal injury showed significant activation of ADAM17 levels accompanying epithelial-stromal detachment. Corneas treated with hydroxamates starting 2 hours post exposure showed a dose-dependent ADAM17 activity inhibition up to concentrations of 3 nmol. Of the four hydroxamates, NDH4417 (N-octyl-N-hydroxy-2-[4-hydroxy-3-methoxyphenyl] acetamide) was most effective for inhibiting ADAM17 and retaining epithelial-stromal attachment. CONCLUSIONS Mustard exposure leads to corneal epithelial sloughing caused, in part, by the activation of ADAM17 at the epithelial-stromal junction. Select hydroxamate compounds applied 2 hours after NM exposure mitigated epithelial-stromal separation.

Abstract
Corneal alkali burns (CAB) are characterized by injury-induced inflammation, fibrosis and neovascularization (NV), and may lead to blindness. This review evaluates the current knowledge of the molecular mechanisms responsible for CAB. The processes of cytokine production, chemotaxis, inflammatory responses, immune response, cell signal transduction, matrix metalloproteinase production and vascular factors in CAB are discussed. Previous evidence indicates that peroxisome proliferator-activated receptor γ (PPAR-γ) agonists suppress immune responses, inflammation, corneal fibrosis and NV. This review also discusses the role of PPAR-γ as an anti-inflammatory, anti-fibrotic and anti-angiogenic agent in the treatment of CAB, as well as the potential role of PPAR-γ in the pathological process of CAB. There have been numerous studies evaluating the clinical profiles of CAB, and the aim of this systematic review was to summarize the evidence regarding the treatment of CAB with PPAR-γ agonists.

Abstract
Corneal tissue regeneration is of crucial importance for maintaining normal vision. We aimed to isolate and cultivate human corneal stroma-derived mesenchymal stem-like cells (CSMSCs) from the central part of cadaver corneas and study their phenotype, multipotency, role in immunity and wound healing. The isolated cells grew as monolayers in vitro, expressed mesenchymal- and stemness-related surface markers (CD73, CD90, CD105, CD140b), and were negative for hematopoietic markers as determined by flow cytometry. CSMSCs were able to differentiate in vitro into fat, bone and cartilage. Their gene expression profile was closer to bone marrow-derived MSCs (BMMSCs) than to limbal epithelial stem cells (LESC) as determined by high-throughput screening. The immunosuppressive properties of CSMSCs were confirmed by a mixed lymphocyte reaction (MLR), while they could inhibit proliferation of activated immune cells. Treatment of CSMSCs by pro-inflammatory cytokines and toll-like receptor ligands significantly increased the secreted interleukin-6 (IL-6), interleukin-8 (IL-8) and C-X-C motif chemokine 10 (CXCL-10) levels, as well as the cell surface adhesion molecules. CSMSCs were capable of closing a wound in vitro under different stimuli. These cells thus contribute to corneal tissue homeostasis and play an immunomodulatory and regenerative role with possible implications in future cell therapies for treating sight-threatening corneal diseases.

Abstract
We evaluated an anti-inflammatory effect of topical administration of tofacitinib, janus kinase (JAK) blocker, on corneal inflammation. Topical instillation of either tofacitinib or PBS was applied after wounding BALB/c mice corneas with alkali burn. Topical instillation was performed until day 14 after injury and injured eye was analyzed. The vascularized area in the alkali burned cornea was significantly reduced in the tofacitinib group compared with that in the PBS group. The immunoreactivity of Gr-1, F4/80, IFN-γ, and phosphorylated STAT(signal transducer and activator of transcription)1 in corneal stroma was diminished significantly in the tofacitinib group. Using laser capture microdissection system and quantitative PCR array analysis, the expression levels of CXCL9, CXCL5, CCL7, CCL2, MMP(matrix metalloproteinase)-9, and STAT1 in corneal stroma were down-regulated in the tofacitinib group. In in vitro study, human fibroblast pretreated by IFN-γ showed phosphorylation of STAT1, and this phosphorylation was down-regulated by adding tofacitinib to the culture medium. These results indicate the topical application of JAK inhibitor causes down-regulation of JAK- or IFN-γ-related molecules. Therefore, we deduce that application of JAK inhibitor for topical instillation may contribute to the treatment of corneal inflammation.

Abstract
Immune-mediated uveitis may be associated with a systemic disease or may be localized to the eye. T-cell-dependent immunological events are increasingly being regarded as extremely important in the pathogenesis of uveitis. Several studies have also shown that macrophages are major effectors of tissue damage in uveitis. Uveitis phenotypes can differ substantially, and most uveitis diseases are considered polygenic with complex inheritance patterns. This review attempts to present the current state of knowledge from in vitro and in vivo research on the role of genetics in the development and clinical course of uveitis. A review of the literature in the PubMed, MEDLINE, and Cochrane databases was conducted to identify clinical trials, comparative studies, case series, and case reports describing host genetic factors as well as immune imbalance which contribute to the development of uveitis. The search was limited to primary reports published in English with human subjects from 1990 to the present, yielding 3590 manuscripts. In addition, referenced articles from the initial searches were hand searched to identify additional relevant reports. After title and abstract selection, duplicate elimination, and manual search, 55 papers were selected for analysis and reviewed by the authors for inclusion in this review. Studies have demonstrated associations between various genetic factors and the development and clinical course of intraocular inflammatory conditions. Genes involved included genes expressing interleukins, chemokines, chemokine receptors, and tumor necrosis factor and genes involved in complement system. When considering the genetics of uveitis, common threads can be identified. Genome-wide scans and other genetic methods are becoming increasingly successful in identifying genetic loci and candidate genes in many inflammatory disorders that have a uveitic component. It will be important to test these findings as uveitis-specific genetic factors. Therefore, the burgeoning understanding of the human genome promises to result in new insight into the pathogenesis of uveitis.

Matrix metalloproteinases (MMPs) are zinc-dependent endopeptidases with the potential to degrade all types of extracellular matrix. The ADAM (a disintegrin and metalloproteinase) family of peptidases was recently identified as cleaving the extracellular domain of transmembrane proteins. This was termed ectodomain shedding. We investigated the MMP expression in patients with corneal diseases and the potential role of ADAMs in corneal pathophysiology. We detected upregulation of the active form of MMP-2 and MMP-9 in the tear fluid from patients with corneal melting or recurrent corneal erosion. Using human corneal epithelial cells, we observed ADAM17-dependent ectodomain shedding of soluble tumor necrosis factor receptor 1 and soluble interleukin-6 (IL-6) receptor (sIL-6R). The production of sIL-6R was also induced by messenger RNA splicing in the human corneal epithelial cells. IL-6/sIL-6R-induced signal transducer and activator of transcription 3 phosphorylation was observed in cultured human corneal fibroblasts, suggesting that IL-6 trans-signaling induced inflammatory cellular signaling in the human corneal fibroblasts. We demonstrated that MMPs are significantly upregulated in collagen-destructive disorders of the cornea. Additionally, we observed that ectodomain shedding by ADAMs in corneal epithelial cells mediated the production of soluble cytokine receptors. Trans-signaling of IL-6 can induce an inflammatory response in corneal stroma, indicating the significance of IL-6 trans-signaling in ocular surface inflammation. Thus, MMPs and ADAMs play an important role in the pathophysiology of corneal diseases.

Abstract
Neovascularization (NV) in the cornea is a major cause of vision impairment and corneal blindness. Hemangiogenesis and lymphangiogenesis induced by inflammation underlie the pathogenesis of corneal NV. The current mainstay treatment, corticosteroid, treats the inflammation associated with corneal NV, but is not satisfactory due to such side effects as cataract and the increase in intraocular pressure. It is imperative to develop a novel therapy that specifically targets the hemangiogenesis, lymphangiogenesis, and inflammation pathways underlying corneal NV. Histone deacetylase inhibitors (HDACi) have been in clinical trials for cancer and other diseases. In particular, HDACi suberoylanilide hydroxamic acid (SAHA, vorinostat, Zolinza) has been approved by the FDA for the treatment of cutaneous T-cell lymphoma. The functional mechanism of SAHA in cancer and especially in corneal NV remains unclear. Here, we show that topical application of SAHA inhibits neovascularization in an alkali-burn corneal injury model. Mechanistically, SAHA inhibits corneal NV by repressing hemangiogenesis, inflammation pathways, and previously overlooked lymphangiogenesis. Topical SAHA is well tolerated on the ocular surface. In addition, the potency of SAHA in corneal NV appears to be comparable to the current steroid therapy. SAHA may possess promising therapeutic potential in alkali-burn corneal injury and other inflammatory neovascularization disorders.

Abstract
We investigated the effect of soluble IL-6R (sIL-6R) blockade on corneal inflammation. Topical instillation of either anti-IL-6R antibody (MR16-1) or phosphate buffered saline (PBS) was applied after wounding BALB/c mice corneas with alkali burn. The vascularized area was significantly reduced in the MR16-1 group. The immunoreactivity of phosphorylated STAT3, Gr-1, and F4/80 diminished significantly in the MR16-1 group. Laser capture microdissection resulted in a significant down-regulation of the mRNA expressions of ICAM-1, MCP-1, and VEGF-A in the corneal stroma of the MR16-1 group. Adding a combination of recombinant IL-6 and sIL-6R resulted in a significant increase in the release of VEGF from human corneal fibroblasts. As the infiltration of inflammatory cells, the expression of phosphorylated STAT3, and the expressions of inflammatory-related molecules in the experimental model of corneal inflammation were significantly inhibited by topical instillation of MR16-1, we deduce that IL-6 trans-signaling plays a significant role in ocular surface inflammation and that the blockade of IL-6R contributes to the reduction in corneal inflammation.

Expression analysis of ADAM17 during mouse eye development. Ann Anat 2011; 194:334-8.

Abstract
ADAM17 (a disintegrin and metallopeptidase domain 17) is crucial for eye morphogenesis. In this study we analysed the expression pattern of ADAM17 during mouse eye development. ADAM17 expression in adult retina was examined using the reverse transcription-polymerase chain reaction (RT-PCR) and verification of the RT-PCR products by DNA sequencing. Immunohistochemistry was performed to evaluate the ADAM17 expression pattern in mouse eyes at developmental stages of embryonic day (E) 12, E14, E16, E18, postnatal day (P) 0, P1, P4, P7, P14, P 30 and P175 (adult). We detected ADAM17 mRNA in adult retina tissue. ADAM17 protein was expressed in non-pigmented ciliary epithelial cells and in retinal vessels from P7 onwards during eye development. In corneal epithelial cells and endothelium, ADAM17 protein was present from P14 onwards. Although, mice in which the functional ADAM17 gene is significantly reduced develop multiple eye malformations, the expression of ADAM17 is not ubiquitous over the entire eye. Its expression pattern during development suggests that not only TNF-alpha but additional membrane-anchored substrates of ADAM17 play an important role in eye formation.

Abstract
Tumor necrosis factor-alpha (TNF-alpha) converting enzyme (TACE), a member of the family of metalloproteinase disintegrin proteins, is responsible for the conversion of inactive TNF-alpha precursor form to active mature form. TNF-alpha is a pleiotropic cytokine that contributes to cellular immunity and inflammatory response in wide range of inflammatory pathologies. Although a large number of studies indicate the use of TACE inhibitors, which prevents processing of TNF-alpha as potential therapeutic drugs for the treatment of inflammatory diseases including rheumatoid arthritis, Crohn's disease and cancer, very few studies indicate its use in ocular pathologies. It is still not clearly understood how the TACE-mediated shedding of cytokines and growth factors in various ocular tissues plays a critical role in the cytotoxic signals causing tissue dysfunction and damage leading to blindness. Regulation of TACE activity is likely to have wide implications for ocular immunology and inflammatory diseases. Specifically, since anti-TNF-alpha therapies have been used to prevent ocular inflammatory complications, the use of TACE inhibitors could be a novel therapeutic approach for ocular inflammatory diseases especially uveitis.

Abstract
BACKGROUND AND AIMS Adrenal hormones influence inflammatory and fibrotic activity and thereby are involved in wound-healing process. Any excess as well as any shortage of glucocorticoids leads to a delayed wound healing. Mineralocorticoids like aldosterone have a pro-fibrotic and pro-inflammatory impact; thus, reduction of circulating aldosterone should result in an attenuated inflammatory response to implanted foreign bodies. MATERIAL AND METHODS Eighteen rats were bilaterally adrenalectomized and substituted with dexamethasone (12 microg/kg per day) and 1% salt in their drinking water; 22 rats were sham-operated. The surgical suture material was removed after 3 weeks and analyzed for size of granuloma, ratio of collagen type I/III, apoptotic cells (terminal deoxynucleotidyl transferase deoxyuridine triphosphate nick end labeling), expression of matrix metalloproteinase (MMP)-2, cyclooxygenase 2, tumor necrosis factor receptor 2 (TNF-R2), cluster of differentiation 68 (CD68), Ki67, and cold shock protein Y box binding protein 1 (YB-1). Cell expression was scored according to Remmele. RESULTS All animals developed foreign body granulomas around the sutures. Absence of circulating aldosterone after adrenalectomy (ADX) was associated with smaller granuloma size and a reduced ratio of collagen type I/III. Ki67 and MMP-2 showed the strongest expression in cells of the infiltrate around suture. In adrenalectomized rats, we observed significantly less CD68-positive macrophages and less Ki67-positive cells but no significant differences in the expression of YB-1, TNF-R2, or MMP-2. Looking for correlations and co-expressions of proteins, the number of significant Spearman correlations was reduced in the ADX group compared to controls (one and four, respectively). CONCLUSION The absence of circulating aldosterone attenuates inflammatory intensity around suture material. Foreign body granuloma seems to be an appropriate model to study chronic inflammatory process.
