摘要:
Toll样受体(TLR)9与特异性配体结合后,不仅在包括头颈鳞状细胞癌(HNSCC)在内的多种恶性肿瘤的发生发展中高表达,而且具有促进肿瘤细胞增殖、侵袭及转移的作用;但TLR9在一些肿瘤中高表达预示较高的术后复发率及较低的术后生存率,在另一些肿瘤中高表达却是肿瘤预后较好的分子指标。TLR9参与HNSCC的相关分子机制,在于促进细胞增殖、抑制程序性细胞死亡、调节血管新生、促进肿瘤侵袭和促进免疫逃逸。目前,基于TLR9的抗肿瘤治疗已被广泛用于临床,其最终的临床效果尚待进一步了解TLR9的表达调控,分析TLR9参与HNSCC的双刃剑作用机制及相关信号转导环节,开发特异性高、不良反应小和可有效用于临床的TLR9佐剂或抑制剂。
