BackgroundHepatitis A virus cellular receptor 2(HAVCR2)is a single-pass type I membrane protein and it contains 1 Ig-like V-type(immunoglobulin-like) domain. The protein belongs to the immunoglobulin superfamily, and TIM family of proteins. The protein regulates macrophage activation. It inhibits T-helper type 1 lymphocyte(Th1)-mediated auto- and alloimmune responses and promotes immunological tolerance. It may be also involved in T-cell homing and it is receptor for LGALS9. CD4(MIM 186940)-positive T helper lymphocytes can be divided into types 1(Th1) and 2(Th2) on the basis of their cytokine secretion patterns. Th1 cells and their associated cytokines are involved in cell-mediated immunity to intracellular pathogens and delayed-type hypersensitivity reactions, whereas Th2 cells are involved in the control of extracellular helminthic infections and the promotion of atopic and allergic diseases. The 2 types of cells also cross-regulate the functions of the other. TIM3 is a Th1-specific cell surface protein that regulates macrophage activation and enhances the severity of experimental autoimmune encephalomyelitis in mice.

FAQ
  • 如何避免重组蛋白降解?:可在纯化过程中加入蛋白酶抑制剂、低温操作,优化储存条件(如分装冻存于-80°C),并避免反复冻融。某些情况下,可选用蛋白酶缺陷型宿主菌减少降解风险。

  • 如何检测重组蛋白的表达和纯度?:常用SDS-PAGE、Western Blot检测表达,BCA/Bradford法测浓度,HPLC或质谱分析纯度,生物活性实验(如ELISA、酶活检测)验证功能。
