Abstract
Recent advancements in the field of endothelial markers of lymphatic vessels and lymphangiogenic factors have shed light on the association between several ocular diseases and ocular nascent lymphatic vessels. The immune privilege of corneal tissue typically limits the formation of lymphatic vessels in a healthy eye. However, vessels in the eyes can potentially undergo lymphangiogenesis and be conditionally activated. It is evident that nascent lymphatic vessels in the eyes contribute to various ocular pathologies. Conversely, lymphatic vessels are present in the corneal limbus, ciliary body, lacrimal glands, optic nerve sheaths, and extraocular muscles, while a lymphatic vasculature-like system exists in the choroid, that can potentially cause several ocular pathologies. Moreover, numerous studies indicate that many ocular diseases can influence or activate nascent lymphatic vessels, ultimately affecting patient prognosis. By understanding the mechanisms underlying the onset, development, and regression of ocular nascent lymphatic vessels, as well as exploring related research on ocular diseases, this article aims to offer novel perspectives for the treatment of such conditions.

Abstract
Ocular surface neovascularization and its resulting pathological changes significantly alter corneal refraction and obstruct the light path to the retina, and hence is a major cause of vision loss. Various factors such as infection, irritation, trauma, dry eye, and ocular surface surgery trigger neovascularization via angiogenesis and lymphangiogenesis dependent on VEGF-related and alternative mechanisms. Recent advances in antiangiogenic drugs, nanotechnology, gene therapy, surgical equipment and techniques, animal models, and drug delivery strategies have provided a range of novel therapeutic options for the treatment of ocular surface neovascularization. In this review article, we comprehensively discuss the etiology and mechanisms of corneal neovascularization and other types of ocular surface neovascularization, as well as emerging animal models and drug delivery strategies that facilitate its management.

Pharmacological Inhibition of Glutaminase 1 Attenuates Alkali-Induced Corneal Neovascularization by Modulating Macrophages. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2022; 2022:1106313. [PMID: 35345831 PMCID: PMC8957416 DOI: 10.1155/2022/1106313] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/02/2022] [Accepted: 02/24/2022] [Indexed: 11/18/2022]
Abstract
Corneal neovascularization (CoNV) in response to chemical burns is a leading cause of vision impairment. Although glutamine metabolism plays a crucial role in macrophage polarization, its regulatory effect on macrophages involved in chemical burn-induced corneal injury is not known. Here, we elucidated the connection between the reprogramming of glutamine metabolism in macrophages and the development of alkali burn-induced CoNV. Glutaminase 1 (GLS1) expression was upregulated in the mouse corneas damaged with alkali burns and was primarily located in F4/80-positive macrophages. Treatment with a selective oral GLS1 inhibitor, CB-839 (telaglenastat), significantly decreased the distribution of polarized M2 macrophages in the alkali-injured corneas and suppressed the development of CoNV. In vitro studies further demonstrated that glutamine deprivation or CB-839 treatment inhibited the proliferation, adhesion, and M2 polarization of bone marrow-derived macrophages (BMDMs) from C57BL/6J mice. CB-839 treatment markedly attenuated the secretion of proangiogenic factors, including vascular endothelial growth factor-A (VEGF-A) and platelet-derived growth factor-BB (PDGF-BB) from interleukin-4- (IL-4-) regulated M2 macrophages. Our findings revealed that GLS1 inhibition or glutamine deprivation prevented alkali-induced CoNV by inhibiting the infiltration and M2 polarization of macrophages. This work suggests that pharmacological GLS1 inhibition is a feasible and effective treatment strategy for chemical burn-related CoNV in humans.

CXCR7 Inhibits Fibrosis via Wnt/ β-Catenin Pathways during the Process of Angiogenesis in Human Umbilical Vein Endothelial Cells. BIOMED RESEARCH INTERNATIONAL 2020; 2020:1216926.

Abstract
Although SDF-1/CXCR7 plays an important role in angiogenesis, the function and the pathway of the SDF-1/CXCR7 axis might depend on the cell type or tissue origin and not fully understood. In this study, we investigated the effect of CXCR7 in SDF-1-induced proliferation, migration, apoptosis, tube formation, and endothelial-to-mesenchymal transition (EndMT) of human umbilical vein endothelial cells (HUVECs), and the potential pathway of SDF-1/CXCR7. We confirmed that the silencing of CXCR7 inhibited the proliferation of HUVECs and contributed the apoptosis, while overexpressed CXCR7 increased SDF-1-induced HUVECs migration and tube formation. However, upregulated CXCR7 inhibited the expression of α-SMA, suggesting that CXCR7 might attenuate EndMT. In addition, overexpressed CXCR7 activated AKT and ERK signaling pathways but suppressed Wnt/β-catenin pathways in HUVECs. The inhibition of Wnt/β-catenin pathways decreased the expression of α-SMA. Altogether, these results suggest that CXCR7 might inhibit fibrosis via Wnt/β-catenin pathways during the process of angiogenesis.

Abstract
Purpose: To compare the therapeutic effects of human derivatives in a mouse alkali burn model. Methods: The right eyes of mice were injured using NaOH. After alkali injury, one of the following agents was topically administered for 7 d: human amniotic membrane (hAM) suspension, human umbilical cord serum (hUCS), and human peripheral blood serum (hPBS), or saline. The epithelial defect areas on days 1, 2, and 3 degrees of opacity on days 2, 3, and 7, and corneal neovascularization (NV) areas on day 7 were evaluated. Histologic examination and mRNA expression levels of tumour necrosis factor (TNF)-α, interleukin (IL)-6, vascular endothelial growth factor (VEGF), matrix metalloproteinase (MMP)-2, MMP-8, and MMP-9 were also evaluated on day 7. Results: The epithelial defect areas in the hUCS group were smaller than those in the control and hPBS groups on day 3 (p < .05, respectively). The epithelial defect areas in the hAM suspension group showed smaller than those in the control and hPBS groups on days 1 and 2 (p < .05, respectively). The degrees of opacity were lower in all treatment groups than that of the saline control group on day 7 (p < .05, respectively). Corneal NV areas were not different among groups on day 7 (p = 0.20). The expression levels of TNF-α, IL-6, MMP-8, and MMP-9 mRNA and the infiltration of the inflammatory cells in all treatment groups were lesser than those in the control group on day 7 (p< .05, respectively). Conclusions: All treatments reduced inflammatory reactions and corneal opacity development. Corneal reepithelialization was faster in the hUCS group.

Abstract
The cornea is unique because of its complete avascularity. Corneal neovascularization (CNV) can result from a variety of etiologies including contact lens wear; corneal infections; and ocular surface diseases due to inflammation, chemical injury, and limbal stem cell deficiency. Management is focused primarily on the etiology and pathophysiology causing the CNV and involves medical and surgical options. Because inflammation is a key factor in the pathophysiology of CNV, corticosteroids and other anti-inflammatory medications remain the mainstay of treatment. Anti-VEGF therapies are gaining popularity to prevent CNV in a number of etiologies. Surgical options including vessel occlusion and ocular surface reconstruction are other options depending on etiology and response to medical therapy. Future therapies should provide more effective treatment options for the management of CNV.

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
PURPOSE To investigate the role of CXCR4 and cyclooxygenase-2 in pterygium recurrence. METHODS A total of 18 primary and 9 recurrent pterygium samples were analyzed. Immunohistochemical staining using primary antibodies against cyclooxygenase-2 and CXCR4 was performed. The cyclooxygenase-2 and CXCR4 expressing cells were calculated separately on the epithelium and stroma. In addition, a correlation between the area of pterygium and CXCR4 and cyclooxygenase-2 levels was investigated. RESULTS In the primary pterygium group, cyclooxygenase-2 staining was more intense in the epithelium and more dominant in the stroma of the recurrence samples. The CXCR4 expression was more intense in the stroma of both groups. The highest CXCR4 expression was observed in the recurrent pterygium group. There was a strong correlation between the area of pterygium and CXCR4 and cyclooxygenase-2 of stroma. CONCLUSIONS CXCR4 and cyclooxygenase-2 may play an important role in the recurrence of pterygium.
