Figure 3. Deficiency of Syk elevated IFNβ production and leads to the enhancement of STATs phosphorylation.
Wild type and Syk deficiency cells were pretreated with IFNβ neutralizing antibody or isotype control for 2 h and then stimulated with LPS. Cell lysates were prepared at the indicated time points and then analyzed by Western blot. (A) Blots were probed with antibodies to phospho-STATs and GAPDH as a loading control; (B) Densitometric quantification of the ratio of phospho-STATs to total-GAPDH.
