Tumor necrosis factor receptor astrocyte

TABLE III Tumor Necrosis Factor Receptor Shedding by Human Fetal Astrocytes"... 

Astrocytes were purified and treated in the same manner as described in Table I, except that some cultures were stimulated for 5 and 7 days. After stimulation cell supernatants were removed, stored at -40°C, and then assayed for soluble tumor necrosis factor receptor type 1 (sTNF-Rl) and sTNF-R2 (Quantikine kits, R8cD Systems, Minneapolis, MN), tumor necrosis factor a (TNFa) (Quantikine HS, R cD Systems), and total nitric oxide (NOj) (in collaboration with L. J. Ignarro, UCLA, Los Angeles). Values are expressed as means SD. IFN, Interferon-y IL-1/3, interleukin-l 8.
