Figure 4.
SOCS1 mRNA expression is up-regulated by IL-6. Freshly isolated T cells were incubated with IL-6 (10 ng/ml) or without IL-6 for 24 hr. In the upper panel the SOCS1 signal is shown. In the lower panel the β2µG signal shows that comparable amounts of product were amplified for each condition. Results shown are representative of three independent experiments.
