摘要

糖尿病(DM)是一组代谢疾病,已知可引起结构和功能性眼部并发症。在人类角膜中,dm相关并发症影响上皮、间质和神经。单羧酸转运蛋白(mct)是一个质子连接的质膜转运蛋白家族,它携带单羧酸盐穿过质膜。在角膜健康和疾病的背景下,它们的作用、存在和功能在很大程度上是不确定的,只集中在最常见的MCT亚型1到4上。在这项研究中,我们利用已建立的3D自组装细胞外基质(ECM)体外模型,研究了MCT1、2、4、5、8和10在角膜DM中的调控作用。从健康(hcf)、I型(t1dm)和II型(t2dm) DM供体中分离出原发性角膜间质成纤维细胞。通过用稳定的维生素C刺激transwell上的基质细胞两周或四周,建立了单培养3D结构。在单培养的基础上,以12 k和500 k两种不同的密度添加SH-SY5Y神经元,形成共培养3D结构。我们的数据显示,在HCF、T1DM和T2DM单培养以及500k神经共培养中,MCT1在4周时显著上调。MCT8在HCF和T1DM单培养和所有50万神经共培养中显著上调。此外,在所有共培养中,MCT10仅在4周时表达,并且在单培养中仅限于hcf和t1dm。免疫荧光分析显示,与t1dm和t2dm相比,所有细胞类型的细胞质MCT表达和hcf中MCT2和MCT4的显著下调。在此,我们揭示了mct在人糖尿病角膜中的存在和调控。这些变化依赖于神经元密度,这表明mct很可能是糖尿病角膜病变/神经病变中观察到的神经元缺陷的关键。为了充分描述mct在角膜糖尿病中的作用,需要进一步的研究。

Monocarboxylate Transporters: Role and Regulation in Corneal Diabetes.

Diabetes mellitus (DM) is a group of metabolic diseases that is known to cause structural and functional ocular complications. In the human cornea, DM-related complications affect the epithelium, stroma, and nerves. Monocarboxylate transporters (MCTs) are a family of proton-linked plasma membrane transporters that carry monocarboxylates across plasma membranes. In the context of corneal health and disease, their role, presence, and function are largely undetermined and solely focused on the most common MCT isoforms, 1 through 4. In this study, we investigated the regulation of MCT1, 2, 4, 5, 8, and 10, in corneal DM, using established 3D self-assembled extracellular matrix (ECM) in vitro models. Primary stromal corneal fibroblasts were isolated from healthy (HCFs), type I (T1DMs), and type II (T2DMs) DM donors. Monoculture 3D constructs were created by stimulating stromal cells on transwells with stable vitamin C for two or four weeks. Coculture 3D constructs were created by adding SH-SY5Y neurons at two different densities, 12 k and 500 k, on top of the monocultures. Our data showed significant upregulation of MCT1 at 4 weeks for HCF, T1DM, and T2DM monocultures, as well as the 500 k nerve cocultures. MCT8 was significantly upregulated in HCF and T1DM monocultures and all of the 500 k nerve cocultures. Further, MCT10 was only expressed at 4 weeks for all cocultures and was limited to HCFs and T1DMs in monocultures. Immunofluorescence analysis showed cytoplasmic MCT expression for all cell types and significant downregulation of both MCT2 and MCT4 in HCFs, when compared to T1DMs and T2DMs. Herein, we reveal the existence and modulation of MCTs in the human diabetic cornea in vitro. Changes appeared dependent on neuronal density, suggesting that MCTs are very likely critical to the neuronal defects observed in diabetic keratopathy/neuropathy. Further studies are warranted in order to fully delineate the role of MCTs in corneal diabetes.
