Table 1. Effects of long-chain unsaturated and saturated fatty acids on cytokine release from cultured astrocytes.
Primary astrocyte cultures were established as described in Methods, and exposed to either vehicle (BSA), or BSA-conjugated fatty acids (100 μM final concentration, see Methods). Release of TNFα, IL-6, and IL-1β was measured after 24 h. Data were compiled from 2 separate experiments, and are means and SEM of 10–30 dishes per group.
TNFα (pg/ml) | IL-6 (pg/ml) | IL-1β (pg/ml) | ||
---|---|---|---|---|
BSA | 102.6 ± 8.7 | 999.8 ± 80.5 | 246.1 ± 29.1 | |
Unsaturated FA (0.1 mM) | Myristolate | 32.0 ± 12.5 | 882.0 ± 242.6 | 26.2 ± 6.8 |
Olate | 121.1 ± 21.5 | 673.4 ± 154.8 | 197.1 ± 41.5 | |
Linolate | 146.1 ± 21.4 | 687.5 ± 101.7 | 175.0 ± 25.0 | |
Arachidonate | 140.3 ± 18.3 | 1142.0 ± 276.8 | 347.0 ± 192.9 | |
Saturated FA (0.1 mM) | Laurate | 521.3 ± 60.7*** | 6154.5 ± 724.9*** | 994.5 ± 153.1** |
Palmatate | 849.0 ± 74.9*** | 3120.6 ± 173.0*** | 1229.0 ± 189.1*** | |
Sterate | 430.7 ± 39.5*** | 3163.3 ± 394.4*** | 634.0 ± 118.6 |
indicate significant (p<0.01, and p<0.001, respectively) increases in cytokine release from astrocytes treated with saturated fatty acids as compared to cells treated with BSA alone.
