Although T cells are activated in INS during relapse, as indicated by an increased expression of interleukin (IL)-2 receptor, these cells have a decreased ability to proliferate. The T-cell receptor (TCR) plays an important role in signal transduction and T cell activation, with the TCR-zeta...
其表面存在的T细胞受体(T cell receptor, TCR)能够识别主要组织相容性复合体(major histocompatibility complex, MHC)呈递的抗原多肽,并将抗原结合信号转换为胞内酪氨酸磷酸化信号,引发下游信号通路来激活T细胞。在临床上,T细胞受体工程化T细胞(T cell receptor-engineered...
T-Cells are a subset of lymphocytes that play a large role in the immune response. The TCR (T-Cell Receptor) is a complex of integral membrane proteins that participates in the activation of T-Cells in response to the presentation of antigen.
In mice, tumour induced immune suppression has been associated with a decreased expression of the zeta-chain of the T cell receptor (TCR)-CD3 complex, and loss of mRNA for granzyme B. AIM: To compare the expression of TCR-zeta and granzyme B in lymphocytes infiltrating normal colonic mucosa...
一、CAR-T研究背景 CAR-T(Chimeric Antigen Receptor T cell)，即嵌合抗原受体(CAR)T细胞，是一种新的细胞疗法，从患者身上获取自体T细胞并进行基因修饰以表达嵌合抗原受体。这些受体由细胞外的scFv组成，该scFv被设计成与高特异性靶标结合，以及由共刺激结构和T细胞受体（TCR）zeta链组成细胞内部分[1,2]。这些修饰...

Interaction of the T cell receptor (TCR) with an MHC-antigenic peptide complex results in changes at the molecular and cellular levels in T cells. The outside environmental cues are translated into various signal transduction pathways within the cell, which mediate the activation of various genes ...
