Nitric oxide generators amplify LPS-induced expression of TNF

Replicate monocyte cultures were stimulated with 0.5 ng/ml LPS alone (control) or in combination with generators of NO SNAP (100 µM), SIN (10 µM), or NONO (10 µM). Eighteen hours after stimulation, TNF levels in culture supernatants were assayed by ELISA. Values are scaled relative to LPS-stimulated cultures taken as 100%. Monocytes from two different donors were used, and the results of a representative experiment are presented. Results are shown as mean ± SD of three separate wells. Statistical analysis was performed as in Fig. 1
