AB  - Conjunctival fibrosis often emerges after infections, inflammations and mechanical stresses of the eye and when severe results in impaired vision. Recent data documented unavoidable role of epithelial to mesenchymal transition (EMT) in every fibrotic process including fibrosis-based eye conditions. The aim of this work was to establish whether human conjunctival epithelial (HCjE) cells are prone to EMT induction after prolonged treatment with well-known EMT inducers TGF-β proteins, and to test capabilities of TGF-β1, TGF-β2 and their combination to trigger this process. While TGF-β2 induced only alterations in cell-cell adhesion, TGF-β1 and combination of TGF-β proteins induced prominent change in cell morphology reflected in loss of cell-cell contacts, changes in shape from epithelial polygonal to spindle-like shape typical for mesenchymal phenotype and acquired ability to move. Statistically significant reduction of mRNA expression of epithelial marker genes (CDH1, OCLN, DSP) was observed in all treatment groups, while mRNA expression level of mesenchymal marker genes (CDH2, FN1, VIM) and EMT-related transcription factors (SNAI1, ZEB2, TWIST1) varied among treatment groups. TGF-β1 treatment induced the most pronounced increase in the level of mRNA of genes characteristic for mesenchymal phenotype that was accompanied with corresponding increase in protein level of two mesenchymal markers (CDH2, FN1), in parallel with decrease in protein expression of two epithelial markers (CDH1, DSP). To conclude, HCjE cells are prone to EMT induction and TGF-β1 possesses the highest potential for EMT induction in HCjE cells, suggesting that, in conditions of chronic inflammation, induction of EMT in conjunctival cells could contribute to fibrosis-related eye diseases.

AB  - Purpose : Bacterial ghosts (BGs) are empty cell envelopes derived from Gram-negative bacteria. BGs possess all cell membrane structures, like live bacteria they are originated from, which gives a potential to use them as an adjuvant delivery system. In the present study, we investigated the potential of Escherichia coli Nissle (EcN) and Salmonella typhimurium (Sty) BGs in modulation of immune responses in human conjunctival epithelial cells (HCjE).
Methods : Confluent monolayers of HCjE cells were treated for 2 and 24 hours with EcN and Sty BGs at a concentration of 1x108 particles/ml, as well as with Interleukin- 1α as a general stimulator. 24 hours after cell stimulation the supernatants and cells were collected. Concentration of IL-6 and IL-8 were measured using ELISA. Quantification of the gene expression levels for TLR-4 and TLR-5 was performed using qRT-PCR.
Results : HCjE cells responded to EcN BGs and Sty BGs with increased secretion of pro-inflammatory cytokines and expression of toll-like receptors (TLRs). Expression of TLR-4 and TLR-5 was significantly higher in EcN BGs stimulated cells compared to Sty BGs stimulated HCjE cells (P<0.05). EcN and Sty BGs induced enhanced secretion of IL-6 and IL-8 in HCjE cells.
Conclusions : Our results suggest that both used BGs may modulate the secretion of IL-6 and IL-8 mainly via the activation of TLR-4 and TLR-5 in HCjE cells.

AB  - Purpose : Epithelial-mesenchymal transition (EMT) of conjunctival epithelium may contribute to trachoma-associated conjunctival fibrosis. Epigenetic mechanisms have an important role in different disease etiologies, however, it is unknown whether they play a role during Chlamydia trachomatis (Ct) ocular infection. The aim of this study was to test the ability of Ct to induce EMT in human conjunctival epithelial (HCjE) cells in vitro and investigate whether alterations in gene expression after Ct infection are correlated with DNA methylation of EMT related marker genes.
Methods : mRNA and protein expression levels of EMT markers, including TGFβ1 and TGFβ2, E-cadherin (CDH1), fibronectin (FN1) and α-smooth muscle actin (ACTA2) were assayed by qPCR and Western blot analysis in HCjE cells infected with Ct serovar B. Promoters and gene-bodies of CDH1, FN1 and ACTA2 were analyzed for the presence of CpG islands using CpG Island Searcher software and thereafter changes in DNA methylation patterns of selected regions were examined with MSP, HRM and bisulfite sequencing.
Results : Infection of HCjE cells with Ct resulted in a statistically significant increase in TGFβ1 and TGFβ2 mRNA and significant reduction of mRNA expression of E-cadherin gene (CDH1), wherein CDH1 mRNA expression was 2.7-fold higher in a control than in Ct infected HCjE cells. Decrease in mRNA expression was accompanied with diminishment in protein level of E-cadherin after Ct infection. HRM data showed convincing difference between control and Ct infected level of DNA methylation with increase from 12.8% to 21.8% suggesting that CDH1 promoter region is subjected to alterations in DNA methylation in HCjE cells because of Ct infection.
Conclusions : Our data for the first time indicate a direct role of Ct infection in epigenetic regulation of human conjunctival epithelium. Studying the pathways of EMT in HCjE cells may help to develop new therapeutic strategies to treat conjunctival fibrosis.

AB  - Repeated eye infections with Chlamydia trachomatis (Ct) usually lead to conjunctiva! scarring, corneal damage and blindness (trachoma). Considering epithelial to mesenchymal transition (EMD as unavoidable player in the development of fibrosis and taking into account that EMT is epigenetically reg­ulated process, our intention was to explore whether Ct infec­tion induces EMT in vitro and to uncover potential underlying epigenetic mechanisms. 
Human conjunctiva! epithelial cells were infected with 107 IFU of Ct for 72 h. The mRNA and protein expression of EMT mark­ers (E-cadherin and fibronectin) were assessed by RT-qPCR, lmmunoblotting and lmmunocytochemfstry. DNA methyfation analysis of selected regions of marker genes were examined by MSP, HRM and Bs-Seq. 
The Ct infection induced EMT-related changes in mRNA and protein expression, downregulation of epithelial marker E-cadherin and upregulation of mesenchymal marker fibronectin. Increase in DNA methylation of E-cadherin gene promoter was in correlation with its decreased expression, while DNA meth­ylation status of fibronectin gene couldn't be related to its ex­pression level. 
We suggest that manipulating the EMT process via modula­tion of DNA methylation of E-cadherin opens up possibilities to stop or revers the progression of scarring as a new strategy in trachoma treatment.
