Abstract

Objective: Ocular chemical burns are a leading cause of blindness. The cornea is injured by alkali-induced oxidative disturbances and an inflammatory response. The aim of this study was to evaluate the protective effects of aloin, an antioxidant, and anti-inflammatory compound, on corneal alkali burn.

Materials and methods: Mice eyes were injured by NaOH and subsequently treated with aloin eye drop and intraperitoneal injection. Pathological characteristics of the eyes were examined, and corneal samples were collected for further analysis.

Results: Aloin diminished neutrophil infiltration and the production of proinflammatory cytokines. Aloin also attenuated apoptosis in human corneal epithelial cells (HCEs) by reducing oxidative stress through the activation of the Nrf2 pathway. Additionally, aloin suppressed the formation of neutrophil extracellular traps (NETs) and inhibited their deposition on the cornea. Moreover, aloin mitigated alkali-induced apoptosis in HCEs caused by NETs.

Conclusions: These findings suggest that aloin has potential as an antioxidant and anti-inflammatory compound for treating corneal alkali burn by inhibiting NETs formation and promoting Nrf2.

芦荟素通过抑制中性粒细胞胞外捕获物和促进 Nrf2 减轻碱烧伤对角膜的损伤。
目的:眼部化学烧伤是导致失明的主要原因之一。角膜因碱引起的氧化紊乱和炎症反应而受伤。本研究旨在评估芦荟素(一种抗氧化剂和抗炎化合物)对角膜碱烧伤的保护作用:材料和方法:用 NaOH 伤害小鼠眼睛,然后用阿洛因滴眼液和腹腔注射治疗。结果:阿洛因能减少中性粒细胞在角膜上的分布:结果:阿洛因减少了中性粒细胞的浸润和促炎细胞因子的产生。芦荟素还能通过激活 Nrf2 途径减少氧化应激,从而减轻人角膜上皮细胞(HCEs)的凋亡。此外,芦荟素还能抑制中性粒细胞胞外捕获物(NET)的形成,并抑制其在角膜上的沉积。此外,阿洛因还能减轻碱诱导的由NETs引起的HCEs细胞凋亡:这些研究结果表明,芦荟素具有抗氧化和抗炎的潜力,可通过抑制NETs的形成和促进Nrf2来治疗角膜碱烧伤。

期刊介绍: The journal Immunopharmacology and Immunotoxicology is devoted to pre-clinical and clinical drug discovery and development targeting the immune system. Research related to the immunoregulatory effects of various compounds, including small-molecule drugs and biologics, on immunocompetent cells and immune responses, as well as the immunotoxicity exerted by xenobiotics and drugs. Only research that describe the mechanisms of specific compounds (not extracts) is of interest to the journal. The journal will prioritise preclinical and clinical studies on immunotherapy of disorders such as chronic inflammation, allergy, autoimmunity, cancer etc. The effects of small-drugs, vaccines and biologics against central immunological targets as well as cell-based therapy, including dendritic cell therapy, T cell adoptive transfer and stem cell therapy, are topics of particular interest. Publications pointing towards potential new drug targets within the immune system or novel technology for immunopharmacological drug development are also welcome. With an immunoscience focus on drug development, immunotherapy and toxicology, the journal will cover areas such as infection, allergy, inflammation, tumor immunology, degenerative disorders, immunodeficiencies, neurology, atherosclerosis and more. Immunopharmacology and Immunotoxicology will accept original manuscripts, brief communications, commentaries, mini-reviews, reviews, clinical trials and clinical cases, on the condition that the results reported are based on original, clinical, or basic research that has not been published elsewhere in any journal in any language (except in abstract form relating to paper communicated to scientific meetings and symposiums).
