BackgroundMouse Programmed cell death 1 ligand 1(Cd274,PD-L1), is a member of the growing B7 family of immune proteins.It involved in the costimulatory signal essential for T-cell proliferation and IFNG production in a PDCD1-independent manner. Interaction with PDCD1 inhibits T-cell proliferation by blocking cell cycle progression and cytokine production.B7-H1 has been identified as one of two ligands for programmed death1(PD1), a member of the CD28 family of immunoreceptors. B7-H1 is constitutively expressed in several organs such as heart, skeletal muscle B7-H1 expression is upregulated in a small fraction of activated T and B cells and a much larger fraction of activated monocytes. The costimulatory function of B7-H1 is critical for enhancing maturation and differentiation of T-cells in lymphoid organs.B7-H1 expression is also induced in dendritic cells and keratinocytes after IFN gamma stimulation. Interaction of B7-H1 with PD1 results in inhibition of TCR-mediated proliferation and cytokine production. The B7-H1:PD1 pathway is involved in the negative regulation of some immune responses and may play an important role in the regulation of peripheral tolerance.

FAQ
  • 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。

  • 重组蛋白纯化常用的方法有哪些?

    常用的纯化方法包括亲和层析(如His-Tag、GST-Tag)、离子交换层析、疏水相互作用层析(HIC)和凝胶过滤层析。具体方法取决于蛋白特性和标签类型。
