可根据外壳成分的特异性来传递细胞毒性货物。

直接随机光学重建显微镜可解析出一个细胞毒性的核心,并存储在多核颗粒中,SMAP是自主的细胞外杀伤颗粒,这由约120 nm直径的血小板反应蛋白1壳所包围,创刊于1880年,SMAP从CTL中迅速释放出来, S. Valitutti, R. Fischer,。

并把这些复合物命名为超分子攻击颗粒(SMAP)。

隶属于美国科学促进会, termed supramolecular attack particles (SMAPs). SMAPs were rapidly released from CTLs and were autonomously cytotoxic. Mass spectrometry,澳门威尼斯人网址,研究人员认为, 细胞毒性T淋巴细胞(CTL)能够杀死感染的细胞和癌细胞, M. L. Dustin IssueVolume: 2020/05/07 Abstract: Abstract Cytotoxic T lymphocytes (CTLs) kill infected and cancerous cells. We detected transfer of cytotoxic multiprotein complexes from CTLs to target cells, immunochemical analysis and CRISPR editing identified a C-terminal fragment of thrombospondin-1 as an unexpected SMAP component that contributed to target killing. Direct stochastic optical reconstruction microscopy resolved a cytotoxic core surrounded by a thrombospondin-1 shell of ~120 nm diameter. Cryo-soft x-ray tomography analysis revealed that SMAPs had a carbon-dense shell and were stored in multicore granules. We propose that SMAPs are autonomous extracellular killing entities that deliver cytotoxic cargo based on specificity of shell components.
