文献和实验曾让「白发变黑发」,Nature 研究证实这种热门的癌症疗法竟还可以抗衰老!
可能也适用于衰老细胞。 2022 年 11 月 2 日,东京大学等单位的研究人员在 Nature 发表了题为 Blocking PD-L1–PD-1 improves senescence surveillance and ageing phenotypes 的文章。该研究发现应用于癌症治疗的 PD-1 抑制剂还可以清除衰老细胞,发挥抗衰老作用。 研究表明,部分衰老细胞表达免疫检查点程序性死亡配体 1(PD-L1),PD-L1+衰老细胞在体内随年龄增长而积累。PD-L1 阴性细胞对 T
文献速递:个性化循环肿瘤 DNA 可成为免疫治疗疗效新型biomarker
研究背景 使用程序性死亡-1抑制剂或其配体(抗PD-1/PD-L1)的免疫检查点阻断 (ICB) 疗法已成为治疗许多癌症的有效方法。然而仅有少数患者对ICB疗法表现出长期良好的反应,大多数患者对免疫检查点阻断剂都没有阳性反应或因为阻断剂的不良反应而不得不停止服用。虽然已经发现了许多类别的生物标志物,但目前仍未发现强有力的治疗反应预测标志物。寻求新的ICB反应的非侵入性生物标志物能大大提高ICB疗法的临床效果。 研究内容及结果 2020年9月,在Nature子刊Nature Cancer

了 TLS 中 B 细胞通过分泌抗体和细胞因子对抗 PD-1/抗 PD-L1 的反应起关键作用。DC 通过调节抗原加工和呈递来调节 T 细胞功能。B 细胞的功能依赖于 TLS 成熟度,可能是促肿瘤或抗肿瘤。在成熟 TLS 中,B 细胞和 DC 可以通过向 CD8+ 细胞提供肿瘤抗体来更好地训练 CD8+ T 细胞。和明场染色方法相比,Opal 多重免疫荧光染色同时检测更多指标,更可靠地评估 TLS 的成熟度状态。 CD3:T 细胞; CD8: 杀伤性 T 细胞;PD-L-1: 程序性死亡配体
