Day 5 bone marrow derived DC or peritoneal macrophages were incubated for 24 hrs with CRCL (25 μg/ml) or LPS (1 μg/ml) as a positive control. (A) Western blot analysis of total cell extracts was then performed probing for phospho STAT1 (P-STAT1), STAT1, phospho STAT5 (P-STAT5), STAT5, phospho ERK1/2 (P-ERK1/2), ERK1/2, phospho p38 (P-p38), p38, phospho AKT (P-AKT), AKT, phospho STAT3 (P-STAT3), or STAT3.
