Abstract: Nuclear factor-κB(NF-κB)plays an important role in controlling infection,immunity responses,cellar differentiation and apoptosis.It is of characteristics especially in neural system.NF-κB exist widely in neural cells and transfer from plasma into nucleolus through diversified activation passages.in addition,NF-κB is also a key factor in the development of the neural system,anti-apoptosis and modulating the activity of glia cells.It is of great significance in the forensic science.

Key words: NF-κB, apoptosis, forensic medicine
