ABSTRACT

OBJECTIVE:

Nuclear factor (NF)-?B is an inducible transcription factor detected in neurons, glial and neural stem cells. It is involved in many biological processes such as inflammation and innate immunity, development, apoptosis and anti-apoptosis. This text is aimed to explain the roles of NF-?B in proliferation, migration and differentiation of neural stem cells. DATA SOURCES The related literatures between January 1987 and September 2006 were collected from the PUBMED with the keywords of "Neural stem cell, Proliferation, Migration, Differentiation/stem cell, Differentiation/NF-?B" in English. STUDY SELECTION Firstly the articles were checked and quotations attached to these articles were looked over. Inclusive criteria the content of the articles must be correlated with roles of NF-?B in proliferation, migration, differentiation of neural stem cell. Exclusive criteria Repetitive research or articles of Meta analysis. DATA EXTRACTION There were 61 correlated articles, 32 articles accorded with inclusive criteria, and 29 articles excluded were olden or repetitive in content. In 32 collected articles, 4 articles referred to adult neural stem cell, 3 articles referred to NF-?B/Rel family and Ⅰ-?B, 11 articles referred to NF-?B and proliferation of neural stem cell, 8 articles referred to NF-?B and migration of neural stem cell and 6 articles referred to NF-?B and differentiation of neural stem cell.

SYNTHESIS:

Neural stem cells were characterized by the capability to undergo self-renewal, cell divisions, to migrate and to differentiate into multiple cell types. Stem cells within the adult brain were found within special areas. Neural stem cells experienced the processes of dissociation, immigration and differentiation. NF-?B was a transcription factor, which can bind to specific DNA-sequences and regulate transcription. NF-?B was involved in induction of proliferation under erythropoietin (EPO), hypoxia conditions and brain injury. The inhibitors of NF-?B such as beta-peptide, nitric oxide acted in negative manner on proliferation of neural stem cells. In migration of neural stem cell, NF-?B was necessary for induction of migration caused by macrophage chemo attractant protein-1, stem cell factor, stromal cell derived factor. The differentiation of neural stem cells toward astrocytic, neuronal, oligodendrocytic and glial lineages was determined by specific signaling cascades. Interleukin-6 family could accelerate the differentiation of neural stem cells to horizontal cells. The differentiation of neuroblastoma cells could be joined by NF-?B.

CONCLUSION:

A great quantity of evidences verifies that NF-?B plays a crucial role in the complicated regulatory mechanism of transcription of neural stem cells.
