Blood:联合抑制Bcl2和NFκB可协同诱导CTCL细胞死亡、限制其肿瘤生长

皮肤T细胞淋巴瘤(CTCL)的治疗方法有限,目前尚无治愈方案。因此,亟需新的靶向性和耐受性良好的治疗方法。近期,Tabea C. Froehlich等研究人员发现二甲基甲酰胺(DMF)可抑制NFκB作为CTCL的存活因子。与此相似,抑制抗凋亡蛋白Bcl2也表现出可诱导CTCL细胞死亡,特别是当与HDAC抑制剂联合使用时。因此,研究人员推测在CTCL的一种新的联合治疗方案中,抑制Bcl2或可以增强对

皮肤T细胞淋巴瘤(CTCL)的治疗方法有限,目前尚无治愈方案。因此,亟需新的靶向性和耐受性良好的治疗方法。

近期,Tabea C. Froehlich等研究人员发现二甲基甲酰胺(DMF)可抑制NFκB作为CTCL的存活因子。与此相似,抑制抗凋亡蛋白Bcl2也表现出可诱导CTCL细胞死亡,特别是当与HDAC抑制剂联合使用时。因此,研究人员推测在CTCL的一种新的联合治疗方案中,抑制Bcl2或可以增强对NFκB的抑制作用,对此进行研究。

结果发现,在体外时,Bcl2抑制剂ABT-199和ABT-263可特异性诱导CTCL患者来源的原发性CD4+细胞死亡,在CTCL细胞系SeAx中具有相同结果,但对于健康供体的T细胞和缺乏Bcl2的CTCL细胞系HH则无此效应。ABT-199和DMF联合治疗可协同特异性诱导CTCL细胞死亡,ABT-199和DMF作用于两条独立的信号通路。

在体内,给予CTCL移植瘤小鼠模型ABT-199和DMF联合治疗可协同诱导CTCL细胞死亡和抑制肿瘤细胞增殖,进而有效减少肿瘤的生长、延长小鼠的总体存活期。无论是从疗效还是耐受性来看,这种联合治疗方案均优于ABT-199单药治疗。

综上所述,本研究表明Bcl2抑制剂和NFκB抑制剂联合具有极大的治疗CTCL的潜能,值得进一步开展研究来进行验证。
