This system realizes the following functions:stimulating signal output,amplifying,collecting and dealing With electronic physiological signals.
本文介绍利用ＰＣ机、８０９８单片机等构成的系统实现刺激信号的输出和对电生理信号的放大、采集、处理的功能。
Now it is becoming clear that costimulatory signals are required for full T/B cell activation and assumed to modulate T/B cells responses as well as other aspects of the immune system.
T/B细胞充分活化需要共刺激信号,共刺激信号不仅能调节T/B细胞反应,对于免疫系统的其它方面亦有作用。
Rejection in kidney transplantation is due to abnormal activation of T cells,activation of T cells depends on the congenerous effect of the first signal and the second signal (costimulatory signal).
T细胞的活化取决于第一信号与第二信号(共刺激信号)的共同作用,第一信号是抗原提呈细胞(antigen presenting cell,APC )提呈的抗原肽-MHC分子( major histocompatibility complex molecules-antigen,MHC-Ag)复合物与T细胞表面的受体(T cell receptor,TCR)结合;第二信号是T细胞表面的共刺激分子与APC表面的配体结合,包括B7-CD28/CTLA4、CD40-CD154等,其中最重要的是由抗原提呈细胞表面的B7分子与T细胞表面的CD28/CTLA4结合产生。
After stimulated by signals, a nerve cell only displays one of the two kinds of reactions: activated or not activated.
受到刺激信号的神经细胞的输出只有两种情况，激发或未被激发。
