趋化因子受体3及其配体在眼部疾病中的作用

Research progress in chemokine receptor 3 and its ligands in ophthalmology

趋化因子受体3 （CCR3）及其配体eotaxin是一种与哮喘和过敏相关的炎性因子,研究发现CCR3及其配体与多种眼科疾病相关,如脉络膜新生血管、变态反应性结膜炎、视网膜中央静脉阻塞、年龄相关性黄斑变性、视网膜变性等.CCR3的生物学功能研究认为,CCR3及其配体eotaxin不仅参与促进嗜酸性粒细胞与肥大细胞的运输,还参与炎症反应过程,了解其在眼部疾病发生及发展过程中的作用对于眼科相关疾病的认识和诊治有重要意义.就CCR3及其配体的结构和生物学功能以及其与一些眼部疾病的关系进行综述.

Chemokine receptor 3 （CCR3） and its ligands eotaxin are inflammatory factors,and they were thought to be related to asthma and allergic diseases before.Recent studies showed that CCR3 plays significant roles in many eye diseases,such as choroidal noevascularization （CNV）,allergic cunjunctivititis,age-related macular degeneration （AMD）,central retinal vein occlusion and retinal degeneration etc.The biological function study suggested that CCR3 and eotaxin participate in not only promoting the transportation of eosinophilic granulocyte and mastocyte but also inflammatory response.To understand the roles of CCR3 and eotaxin in eye diseases has a very important significance for the recognition and treatment of eye diseases.The structure and function of CCR3 and its ligands,and the relationship between CCR3 and some eye diseases were reviewed.
