Therefore, deficiency of costimulatorymolecules on tumor cells is one of the important mechanisms of tumor immune escape.
可见,肿瘤细胞上共刺激分子缺陷是肿瘤免疫逃逸的重要机制之一。

It has been showed that the expressions of costimulatorymolecules are associated with xero organ transplantation rejection.
已有研究表明,共刺激分子的表达与同种异体移植排斥反应有关。

TLR2 is reported to enhance the expression of costimulatorymolecules on the antigen presenting cell, however the regulatory mechanisms are still unclear.
