使用我们的高品质抗体进行癌症免疫治疗的研究


  PD-1 和 LAG-3 是在非功能性 CD8 T 细胞表面发现的具有相似功能的负调控蛋白。已经在几种肿瘤细胞中发现,PD-1 和 LAG-3 是可以上调T细胞衰竭的表面标记物。这些蛋白的上调可以抑制免疫反应,从而影响肿瘤的生长。先前研究表明,使用免疫检点抑制剂可以提高抗肿瘤作用,而没有自身免疫的显性特征。PD-1 重组单克隆抗体(RMPD1-1)和 LAG-3 (人)单克隆抗体(17B4)可作为研究癌症新的潜在免疫治疗靶点的抗体使用。

◆描述


PD-1(也称为细胞程序性死亡蛋白1;CD279)是CD28/CTLA-4免疫受体家族的I型跨膜蛋白,参与信号和免疫调节。CD28/CTLA-4家族成员可以促进T细胞活性(CD28和ICOS),也可以下调T细胞活性(CTLA-4和PD-1)。PD-1在活化的T细胞、B细胞、骨髓细胞和胸腺细胞中均有表达。PD-1与PD-L1(B7-H1;CD274)或PD-L2(B7-DC;CD273)结合后,可抑制TCR介导的T细胞增殖和生成IL-1、IL-4、IL-10和IFN-γ。另外,PD-1结合后也抑制BCR介导的信号传导。PD-1缺陷型小鼠会有外周耐受性缺陷,会自发发展为自身免疫疾病。可溶性的PD-1(sPD-1)能在活化的免疫细胞中表达,并且可以在血清/血浆中分泌。sPD-1或sPD-L1等可溶性检查点,会参与到正负免疫调节,它们在血清、血浆水平的变化会影响癌症的发展、预测和治疗。不同癌症的患者,所检测到sPD-1或sPD-L1水平会有所升高。PD-1(人)ELISA试剂盒是为检测不同的生物体液中特异性sPD-1(人)而开发的。

◆描述

PD-L1(也称为细胞程序性死亡-配体蛋白1;CD274或B7-H1)是B7家族的免疫共抑制成员,通过与受体PD-1(CD279)和CD80(也称为B7-1)的相互作用,发挥出免疫检查位点的功能。PD-L1由造血细胞表达,如T细胞,B细胞和树突细胞,或由细胞因子(如IFN-γ)诱导薄壁细胞表达。PD-1与PD-L1(B7-H1; CD274)或PD-L2(B7-DC; CD273)连接,可以抑制TCR介导的T细胞增殖和生成IL-1、IL-4、IL-10和IFN-γ,并且还可以抑制BCR介导的信号传导。PD-L1与CD80的结合会抑制T细胞增殖。PD-1缺陷型小鼠会有外周耐受性缺陷,会自发发展为自身免疫疾病。可溶性的PD-L1(sPD-L1)能在活化的免疫细胞中表达,并且可以在血清/血浆中分泌。如sPD-1或sPD-L1等可溶性检查位点,会参与到正负免疫调节,它们在血清/血浆水平的变化会影响癌症的发展,预测和治疗。在患有不同癌症的患者中,检测到sPD-L1或sPD-1水平会有所升高。PD-L1(人)ELISA试剂盒是为检测不同的生物体液中特异性sPD-L1(人)而研制的。

生物活性

TPP-1 is a potent inhibitor of the PD-1/PD-L1 interaction. TPP-1 binds specifically to PD-L1 with a high affinity (KD=95 nM). TPP-1 inhibits human tumor growth in vivo via reactivating T-cell function[1].

体外研究
(In Vitro)

TPP-1 binds to PD-L1 with high affinity and blocks PD-1/PD-L1 interaction. The KD value of PD-L1 with TPP-1 peptide is about 95 nmol/L (around five times less than that with PD-1), The binding site of TPP-1 to PD-L1 is close to the interactive site of PD-1 and PD-L1[1].
TPP-1 (4 μM) reactivates T-cell functions, it induces IFNγ release significantly higher than control and SPP-1, and the TPP-1 group shows similar outcomes for cell proliferation[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究
(In Vivo)

TPP-1 (subcutaneous injection; 4 mg/kg; every other day eight times; 32 days) inhibits tumor growth (compared with SPP-1 and control). The growth rate in TPP-1-treated mice is 56%. And when administered in the absence of T cells (control group), TPP-1 has no effect on the growth of the H460-luc tumors[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: 5 to 6-week-old female Balb/c nude mice  injected with H460 cells transfected with the plvx-puro/luciferase lentiviral vector[1]
Dosage: 4 mg/kg
Administration: Subcutaneous injection; 4 mg/kg; every other day eight times; 32days
Result: Inhibited the tumor growth in a tumor xenograft model via reactivating T-cell function.
