白细胞介素2受体(IL-2R)因其在IL-2介导免疫反应中的重要作用,已成为国内外免疫学领域研究的热点之一。已知存在于细胞膜上的低亲合力受体P55蛋白(Tac 抗原)与P75蛋白共同构成了高亲合力受体,并与IL-2形成具有功能活性的三聚体。大量的工作加深了人们对IL-2R 结构及功能的认识。尤其对P55的了解已深入到分
Interleukin 2 receptor (IL-2R) has become one of the hotspots in the field of immunology at home and abroad because of its important role in IL-2-mediated immune response. It is known that the low affinity receptor P55 protein (Tac antigen) present on the cell membrane together with the P75 protein constitutes a high affinity receptor and forms a functionally active trimer with IL-2. A lot of work has deepened people’s understanding of the structure and function of IL-2R. In particular, the understanding of P55 has been deep into points
