细胞因子（ｃｙｔｏｋｉｎｅｓ，ＣＫ）是由免疫活性细胞产生的小分子糖蛋白，通过对细胞功能的调控而参与炎症和防御机制，近年发现一些非免疫组织的细胞（包括成纤维细胞、内皮和上皮细胞）也具有在炎症反应中产生ＣＫ的能力，可在鼻息肉（ＮＰ）的微环境中对白细胞和组织细? Cytokines (CK) are small-molecule glycoproteins produced by immunocompetent cells. They are involved in inflammation and defense mechanism through the regulation of cell functions. In recent years, some non-immune cells (including fibroblasts, endothelial cells and epithelial cells ) Also has the ability to produce CK in the inflammatory response that can be fine in the microenvironment of the nasal polyps (NPs) against leukocytes and tissues.
