Liu Y, Hong J, Peng R. SAA1 as a key mediator of immune inflammatory pathways in fungal keratitis through FOXO3a phosphorylation regulation. Cytokine 2025; 189:156898. [PMID: 40020519 DOI: 10.1016/j.cyto.2025.156898] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2024] [Revised: 02/12/2025] [Accepted: 02/16/2025] [Indexed: 03/03/2025]
Abstract
OBJECTIVE Fungal keratitis (FK) is a severe ocular infection, with its underlying molecular mechanisms remaining incompletely understood. This study aimed to identify and investigate key genes involved in immune-inflammatory responses associated with FK pathogenesis using bioinformatics and in vitro assays. METHODS Transcriptomic data from the Gene Expression Omnibus (GEO) database (GSE58291) were analyzed using the limma package to identify differentially expressed genes (DEGs). Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed to evaluate significant biological processes and pathways related to DEGs. Weighted gene co-expression network analysis (WGCNA) identified gene modules linked with FK-associated DEGs, and Venn diagram analysis highlighted core genes. Receiver operating characteristic (ROC) analysis assessed diagnostic potential. Immune cell composition was analyzed using CIBERSORT, and correlations between key genes and immune cells were evaluated. In vitro, human corneal epithelial cells (HCEC) were stimulated with Aspergillus fumigatus (A.F.), and pro-inflammatory cytokine expression (IL-1β, TNF-α, IL-6) was assessed using enzyme-linked immunosorbent assay (ELISA). Western blot and quantitative real-time polymerase chain reaction (RT-qPCR) analyzed FOXO3a phosphorylation and gene expression changes post-SAA1 siRNA transfection. RESULTS A total of 101 DEGs were identified, with WGCNA revealing 6 co-expression network modules, with significant associations noted in yellow and black modules. Nine shared genes were identified in DEGs and modules, with SAA1 strongly linked to FK pathogenesis. SAA1 expression was positively correlated with neutrophils, T cells CD4 memory activated, T cells gamma delta, and activated mast cells. Upon stimulation with A.F., cytokine expression increased, peaking at 24 h. Inhibition of SAA1 reduced FOXO3a phosphorylation and pro-inflammatory cytokine levels, underscoring SAA1's role in FK inflammation via FOXO3a regulation. CONCLUSION SAA1 is a key gene in FK, promoting inflammation by modulating FOXO3a phosphorylation. This highlights its potential as a therapeutic target in managing FK-related inflammation.

Thymol Impacts the Progression of Endometriosis by Disrupting Estrogen Signaling Pathways and Inflammatory Responses. Int J Mol Sci 2024; 25:13150. [PMID: 39684860 DOI: 10.3390/ijms252313150] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2024] [Revised: 11/14/2024] [Accepted: 11/24/2024] [Indexed: 12/18/2024] Open
Abstract
Endometriosis is a chronic inflammatory, estrogenic disorder caused by endometrial tissue growth places other than uterine lumen, resulting in infertility and severe pelvic pain. Thymol, an extract of Thymus vulgaris, processes diverse biological properties, including anti-inflammatory, local anesthetic, decongestant, and antiseptic effects. However, the efficacy of thymol in treating endometriosis has still not been explored. Herein, this research aimed to investigate the role of thymol in the treatment of endometriosis using a murine model and Ishikawa cells. Thirty C57BL/6 mice were administered 17β-E2 (100 ng/mouse) subcutaneously for three consecutive days to induce synchronous estrus. On the last day of injection, the mice underwent surgical induction of endometriosis. After that, the mice were divided into three groups, i.e., Control (CTRL), Thymol 30 mg/kg and Thymol 60 mg/kg, receiving oral administration of either saline or thymol (30 mg/kg/d or 60 mg/kg/d, as 0.1 mL/kg/d, respectively) for a three-week duration. Each group consisted of ten mice and was evenly divided into estrus and diestrus according to the vaginal cytology on the last day of treatment. Thymol significantly (p < 0.05) reduced the weight and volume of ectopic tissue, hindered cell proliferation, and stimulated apoptosis compared to the CTRL group. Additionally, in the thymol-treated group, the levels of pro-inflammatory cytokines, tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, and IL-6, as well as the numbers of neutrophils and macrophages, were significantly (p < 0.05) decreased. Moreover, a novel role of thymol in rebalancing estrogen and progesterone (E2-P4) signaling was explored, and it was distributed in the ectopic endometrium. Next, the role of thymol on Ishikawa cells was determined. The results demonstrated that thymol significantly (p < 0.05) suppressed the E2-induced proliferation of Ishikawa cells. Furthermore, molecular docking analyses suggested that thymol potentially binds to ESR1-like estrogens, indicating its antagonistic activity against estrogens. The estrogen receptor 1 (ESR1) and its target gene expression exhibited significant (p < 0.05) downregulation, while progesterone receptor (PGR) and target genes were markedly (p < 0.05) upregulated following thymol treatment in the ectopic endometrium. Most importantly, our data revealed the minimal impact of thymol treatment on the eutopic endometrium and its crucial role in supporting pregnancy, thus indicating the safety of thymol in treating endometriosis. Overall, our study suggests that thymol holds promising therapeutic implications for endometriosis by virtue of its anti-inflammatory properties and ability to antagonize estrogen activity.

Abstract
The cornea functions as the primary barrier of the ocular surface, regulating temperature and humidity while providing protection against oxidative stress, harmful stimuli and pathogenic microorganisms. Corneal diseases can affect the biomechanical and optical properties of the eye, resulting in visual impairment or even blindness. Due to their diverse origins and potent biological activities, plant secondary metabolites known as polyphenols offer potential advantages for treating corneal diseases owing to their anti-inflammatory, antioxidant, and antibacterial properties. Various polyphenols and their derivatives have demonstrated diverse mechanisms of action in vitro and in vivo, exhibiting efficacy against a range of corneal diseases including repair of tissue damage, treatment of keratitis, inhibition of neovascularization, alleviation of dry eye syndrome, among others. Therefore, this article presents a concise overview of corneal and related diseases, along with an update on the research progress of natural polyphenols in safeguarding corneal health. A more comprehensive understanding of natural polyphenols provides a novel perspective for secure treatment of corneal diseases.

Abstract
The eyelid-related disease of blepharitis remains a tricky ocular disorder and affects patient compliance. However, there is no available and effective treatment, making it extremely challenging. Herein, an antibacterial system based on antibiotic delivery was developed and applied in a blepharitis model induced by bacteria. The antibacterial tests against Staphylococcus aureus both in vitro and in vivo demonstrated that the system shows a favorable bactericidal effect. Then, histological evaluation indicated that the system shows both antibacterial and anti-inflammatory effects. This facile design provided an effective ocular infection management, which displays a promising prospect while addressing other complex ocular disorders.

Abstract
During infectious keratitis, the production of collagenolytic and inflammatory substances, along with increased corneal matrix metalloproteinase (MMP) activity, induces the degradation of corneal collagen and may cause postkeratitis complications, such as opacity, thinning, and corneal perforation. MMPs, especially MMP-2 and MMP-9, are overexpressed in infectious keratitis and sustained over time by inflammatory and nonmicrobial mechanisms. The high MMP levels are correlated with excessive corneal destruction in bacterial, herpetic, fungal, and acanthamoeba infections. Nonspecific treatments, such as tetracyclines, particularly doxycycline, or corticosteroids, are used as adjuvants to antimicrobials to alleviate the disproportionate degradation and inflammation of the corneal layers caused by corneal MMPs and decrease the recruitment and infiltration of inflammatory cells. Treatments showing inhibition of specific MMPs (Galardin, ZHAWOC7726), interfering with pro-MMP activation (EDTA, ascorbic acid), or showing anticytokine effect (epigallocatechin-2-gallate, TRAM-34) have been reported. Other treatments show a direct action over corneal collagen structure such as corneal cross-linking or have been associated with reduction of MMP levels such as amniotic membrane grafting. Although the use of these drugs has been shown in studies to be effective in controlling inflammation, especially in experimental ones, robust studies are still needed based on randomized and randomized clinical trials to demonstrate their potential effect as adjuvants in the management of infectious keratitis.

Abstract
Purpose To investigate the antifungal and anti-inflammatory effects of 0.01% hypochlorous acid (HCLO) on rats with Aspergillus fumigatus keratitis. Methods The time-kill assay and broth microdilution procedures were used in vitro to demonstrate that 0.01% HCLO was fungicidal and fungistatic. The severity of the disease was evaluated in vivo using a clinical score and slit-lamp photographs. Fungal load, polymorphonuclear neutrophil infiltration, and the production of related proteins were determined using colony plate counting, in vivo confocal microscopy, periodic acid-Schiff staining, fungal fluorescence staining, immunofluorescence staining, myeloperoxidase assay, and Western blotting. Result In vitro, 0.01% HCLO can destroy A. fumigatus spores in 1 minute. The optical density of the 0.01% HCLO group was significantly lower than that of the phosphate-buffered saline control group (P < 0.01), and no visible mycelium was observed using a fluorescence microscope. 0.01% HCLO reduced the severity of A. fumigatus keratitis in rats by decreasing the clinical score, fungal loading (periodic acid-Schiff, plate count, and fungal fluorescence staining), and inhibiting neutrophil infiltration and activity (immunofluorescence staining and myeloperoxidase). Furthermore, the Western blot analysis revealed that 0.01% HCO decreased protein expression levels of tumor necrosis factor-α and IL-1β. Conclusions According to our findings, 0.01% HCLO can kill A. fumigatus spores in vitro. It has antifungal and anti-inflammatory effects on A. fumigatus keratitis in rats. It also inhibited A. fumigatus growth; decreased neutrophil infiltration, tumor necrosis factor-α, and IL-1β expression; and provided a potential treatment for fungal keratitis. Translational Relevance This study provides a potential treatment for fungal keratitis in the clinic.

Abstract
Fungal keratitis is a refractory kind of keratopathy. We attempted to investigate the anti-inflammatory role of thymol on Aspergillus fumigatus (A. fumigatus) keratitis. Wound healing and fluorescein staining of the cornea were applied to verify thymol's safety. Mice models of A. fumigatus keratitis underwent subconjunctival injection of thymol. The anti-inflammatory roles of thymol were verified by hematoxylin-eosin (HE) staining, slit lamp observation, quantitative real-time polymerase chain reaction (qRT-PCR), and Western blotting. In contrast with the DMSO group, more transparent corneas and less inflammatory cells infiltration were detected in mice treated with 50 μg/ml thymol. Thymol downregulated the synthesis of TLR4, MyD88, NF-kB, IL-1β, NLRP3, caspase 1, caspase 8, GSDMD, RIPK3 and MLKL. In summary, we proved that thymol played a protective part in A. fumigatus keratitis by cutting down inflammatory cells aggregation, downregulating the TLR4/ MyD88/ NF-kB/ IL-1β signal expression and reducing necroptosis and pyroptosis.

Abstract
Fungal keratitis is one of the leading causes of blindness worldwide, which has become an increasingly serious threat to public ocular health, but no effective treatment strategies are available now. Pattern recognition receptors (PRRs) of the innate immune system are the first line of host defense against fungal infections. They could recognize pathogen-associated molecular patterns (PAMPs) or damage-associated molecular patterns (DAMPs) and trigger an array of inflammatory responses. Over the last decades, research has resulted in significant progress regarding the roles of PRRs in fungal keratitis. This review will highlight the importance of several pattern recognition receptors (C-type lectin-like receptors, Toll-like receptors, and NOD-like receptors) in regulating the innate immunity under fungal keratitis and describe the crosstalk and collaboration in PRRs contributing to disease pathology. Meanwhile, some potential therapy-based PRRs against corneal fungal infections are discussed.
