(1)肿瘤特异性抗原(tumor specific antigen, TSA):只在癌细胞上发现,在健康细胞上没有。 (2)肿瘤相关抗原(tumor associated antigen, TAA):在肿瘤细胞上高表达,但在健康细胞上表达水平较低。 02 肿瘤特异性抗原和肿瘤相关抗原的主要区别 TSAs和...
将它们与抗TAAs/ tsa抗体联合使用可以提高它们特异性靶向肿瘤细胞的能力。 3.1双特异性抗体 双特异性抗体在提高临床疗效和安全性方面显示出巨大的前景,用于免疫治疗的双特异性抗体主要有三种类型: (1)细胞毒性效应细胞重定向器:通过与TAA/TSA及T细胞受体或CD3复合物的双特异性结合将细胞毒性效应T细胞定向至肿瘤细胞处。

This value is usually measured by an adiabatic or isoperibolic calorimeter, which causes high economic costs and wastes time. The present study is focused on the development of indirect models for heating value prediction of biomass from orange trees Citrus x sinensis Osbeck, almond trees Prunus ...
