The invention is directed to a bispecific chimeric antigen receptor, comprising: (a) at least two antigen-specific targeting regions; (b) an extracellular spacer domain; (c) a transmembrane domain; (d) at least one co-stimulatory domain; and (e) an intracellular signaling domain, wherein each antigen-specific targeting region comprises an antigen-specific single chain Fv (scFv) fragment, and binds a different antigen, and wherein the bispecific chimeric antigen receptor is co-expressed with a therapeutic control. The invention also provides methods and uses of the bispecific chimeric antigen receptors.
本发明涉及一种双特异性嵌合抗原受体,它包括(a)至少两个抗原特异性靶向区;(b)胞外间隔结构域;(c)跨膜结构域;(d)至少一个共刺激结构域;以及(e)胞内信号转导结构域,其中每个抗原特异性靶向区包括抗原特异性单链Fv(scFv)片段,并结合不同的抗原,且双特异性嵌合抗原受体与治疗对照共同表达。本发明还提供了双特异性嵌合抗原受体的方法和用途。
