BackgroundProgrammed cell death 1 ligand 2(PD-L2), also known as butyrophilin B7-DC or PDCD1 ligand 2, belongs to the member of B7 family which can regulate the activation and tolerance of T cells. PD-L2 is one ligand for Programmed cell death 1(PD-1), and the other is PD-L1. These two ligands shares 34% aa sequence identity. Mouse PD-L2 gene encodes a 273 amino acids(aa) protein with a putative 19 aa signal peptide, a 201 aa extracellular region, a 21 aa transmembrane domain and a 32 aa cytoplasmic region. The mouse PD-L2 gene is highly expressed in heart, placenta, pancreas, lung and liver while expressed weakly in spleen, lymph nodes and thymus. Besides, the expression of PD-L2 gene can be induced on dendritic cells grown from peripheral blood mononuclear cells under CSF2 and IL4/interleukin-4 treatment, and up-regulated by IFNG/IFN-gamma stimulation in monocytes. PD-L2 usually functions in a PDCD1-independent manner and is involved in regulating costimulatory signal which is essential for T-cell proliferation and IFNG production. Recent studies demonstrate that the expression of PD-L2 on the tumor cells promotes CD8 T cell–mediated rejection of tumor cells, at both the induction and effector phase of antitumor immunity. Moreover, PD-L2 binds to PD-1 cells and enhances T cell killing in a PD-1–independent mechanism.

FAQ
  • 蛋白溶解后浓度偏低,如何调整?

    低速离心:12,000 rpm, 5分钟,去除不溶物。缓冲液置换:使用超滤离心管(如10 kDa截留分子量)浓缩。

  • 如何提高重组蛋白的可溶性表达?

    可优化表达条件(如降低诱导温度、调整IPTG浓度)、使用促溶标签(如SUMO、GST)、共表达分子伴侣,或尝试不同宿主系统(如哺乳动物细胞或昆虫细胞)以提高可溶性蛋白产量。
