Several genes and cytokines take part in the accommodation of these changes and influence the severity of brain injury , such as tumor necrosis factor a , bel - 2 gene family and ced gene family ( cystein - dependent aspartate - specific protease , caspase ) . they are all has relationship with cell death after tbi and control the different cascade of cell death . there are two kinds of cell death after traumatic brain injury ( tbi ) that is necrosis and apoptosis 脑外伤后脑组织发生的这些改变由许多基因、细胞因子参与调节并影响着损伤程度,除脑水肿外,脑损伤程度主要取决于细胞因子,这些因子包括肿瘤坏死因子- ( tumornecrosisfactor - , tnf - ) , b细胞淋巴瘤白血病- 2 ( b - celllymphoma leukemia - 2 , bcl - 2 )基因中的bcl - 2 、 bax , ced基因家族中的半胱天冬酶( cystein - dependentaspartate - specificprotease , caspase )等,它们都与脑损伤后的神经细胞死亡有关,控制着引起细胞死亡的不同层面。
