免疫原性细胞死亡(immunogenic cell death,ICD)是调节性细胞死亡(Regulated cell death,RCD)的一个特定变体,由应激压力驱动,可以诱导针对死亡细胞抗原的适应性免疫。 RCD三个因素: 抗原性(antigenicity):垂死的细胞必须表达不完全被胸腺耐受性所覆盖的抗原,潜在...
免疫原性细胞死亡(ImmunogenicCell Death,ICD)是一种细胞死亡方式,它在细 胞死亡的同时,能够激活免疫反应,帮助身 体识别并清除异常细胞。这种死亡方式在免 疫治疗和癌症治疗中具有重要作用。 ICD通常由化疗药物、放疗或光动力治疗等治疗方式引发。这些治 疗方式会导致细胞内某些蛋白质的表达增加,这些蛋白质被称为“损...
免疫原性细胞死亡(immunogenic cell death,ICD)在肿瘤中的应用 肿瘤细胞受到外界刺激发生死亡的同时,由非免疫原性转变为免疫原性而介导机体产生抗肿瘤免疫应答的过程称为免疫原性细胞死亡(immunogenic cell death,ICD)。肿瘤细胞发生ICD的同时,会产生一系列的信号分子,此类物质被称为损伤相关分子模式(damage-associated molec...
ICD是一个过程，当肿瘤细胞受到刺激发生死亡时，转变成能够激发机体免疫反应的免疫原性细胞。这一过程中，肿瘤细胞释放出损伤相关分子模式（DAMPs），包括暴露在细胞表面的钙网蛋白（Calreticulin），向外界分泌的高迁移率族蛋白1（HMGB1），以及细胞释放的ATP分子和热休克蛋白（HSP70，HSP90）。这些DAMPs与DC...
ICD immunogenic cell deathFor years, intratumor injection of bacteria have been purported to be capable of an anticancer effect. However, these bacteria are mostly pathogenic including attenuated and genetically engineered bacteria. The gut microbiota has been discovered to play a key role in ...
Different sets of danger signals are associated with distinct variants of immunogenic cell death. Both pathogens and cancer cells interrupt danger signalling for their own benefit. Reinstating the immunogenicity of cell death holds promise for anticancer therapy. ...
While current cancer therapies rely heavily on apoptosis — a largely immunologically silent form of cell death — there is growing interest in harnessing immunogenic forms of cell death such as necroptosis. Unlike apoptosis, necroptosis generates second messengers that act on immune cells in the ...
Mammalian cells responding to specific perturbations of homeostasis can undergo a regulated variant of cell death that elicits adaptive immune responses. As immunogenic cell death (ICD) can only occur in a precise cellular and organismal context, it shou
1. 什么是免疫原性细胞死亡(immunogenic cell death,ICD)? ICD是调节性细胞死亡(Regulated cell death,RCD)的一种,由应激压力驱动,可以诱导针对死亡细胞抗原的适应性免疫。损伤相关分子模式(DAMPs),包括释放的高迁移率基团1 (HMGB1)蛋白、分泌的三磷酸腺苷(ATP)和表面暴露的钙网蛋白(CRT),是ICD的主要免疫原性特征...
Suggesting a key role for immunogenic cell death (ICD) in immunosurveillance, both pathogens and cancer cells evolved strategies to prevent the recognition of cell death as immunogenic. Intriguingly, normal cells succumbing to conditions that promote the formation of post-translational neoantigens (for...
