Effects of IL-1β and TNFα on MAP kinase expression. Macrophages and endothelial cells isolated from livers of C3H/HeJ mice were incubated with IL-1 β (10 ng/ml), TNFα (10 30 ng/ml) or medium for 20 min. Protein lysates were analyzed by western blotting for expression of total and phosphorylated p38 and p44/42 MAP kinases. One representative of two separate experiments is shown.
