某些血压药物会影响癌症免疫疗法. 洛萨坦和甲酸 (HCTZ) 恶化了纤维瘤模型中的免疫治疗结果,而维拉帕米尔和卡波普利尔改善了它们.
科学领域:
- 在瘤学瘤学.
- 药理学 药理学是指药理学的学科.
- 免疫治疗是一种免疫疗法.
背景情况:
- 高血压和纤维肉瘤往往并存,需要仔细选择药物.
- 免疫疗法是一个不断增长的癌症治疗方式.
- 抗高血压药物和免疫治疗之间的相互作用尚未得到充分理解.
研究的目的:
- 为了研究常见的抗高血压药物对被编程细胞死亡蛋白1抗体 (PD1ab) 免疫治疗在纤维素瘤小鼠模型中的影响.
- 探索观察到的药物效应的潜在机制,特别是对于酸亚化物 (HCTZ).
主要方法:
- 用皮下纤维瘤的小鼠模型来测试六种一线抗高血压药物:维拉帕米尔,洛萨坦,罗塞米德,螺旋,卡普托普里尔和HCTZ.
- 免疫组织化学被用来评估CD8+ T细胞透.
- 进行了体外和体内测试,以阐明HCTZ对人类纤维瘤细胞 (HT1080) 作用的机制.
主要成果:
- 维拉帕米尔和卡普托普里尔增强了PD1ab治疗的抗瘤疗效.
- 螺旋和罗西米德对瘤生长没有影响,但降低了PD1ab的疗效.
- 洛萨坦和HCTZ促进了瘤生长,并减弱了PD1ab治疗效果,HCTZ的机制可能涉及溶性载体家族12成员3 (SLC12A3).
结论:
- 抗高血压药物对纤维肌肉瘤PD1ab免疫疗法的疗效有不同的影响.
- 维拉帕米尔和卡普托普里尔显示出作为PD1ab治疗的辅助剂的潜力.
- 当与PD1ab免疫疗法同时使用时,洛萨坦和HCTZ可能会有害,因此需要进一步调查通过SLC12A3.3.对HCTZ的作用.
