TNF-alpha-induced chemokine production and apoptosis in human neural precursor cells.

abstract：:Leukocytes are a large population of cells spread within most tissues in the body. These cells may be either sessile (called as resident cells) or circulating leukocytes, which travel long journeys inside the vessels during their lifespan. Although production and maturation of these leukocytes in adults primarily occu...
