1211-STING激活胰腺癌CD4⁺ T细胞免疫研究
from 聊聊Sci
这项研究探讨了克服胰腺导管腺癌免疫治疗耐药性的新策略。研究人员发现，将免疫检查点阻断疗法与STING激动剂结合的“三联疗法”，能够显著激发小鼠体内的抗肿瘤反应。这种疗效并不依赖于传统的CD8⁺ T细胞，而是由cDC2树突状细胞驱动并激活了CD4⁺ T细胞。被激活的CD4⁺ T细胞通过释放干扰素-γ来抑制肿瘤生长，为治疗这种高度致命的癌症提供了新的免疫学路径。这一发现表明，针对cDC2-CD4⁺ T细胞轴的免疫调节可能成为未来攻克难治性实体瘤的关键。References:Kruse B, Leonhardt B P, Böttcher J P.
