Dex deactivated both PKA–STAT3 and PKC–NF-κB signaling in hDPCs. hDPCs were cotreated with Car (100 μM) or Dex (5 μM) for 2 h. a WB was performed to probe with antibodies for the phosphorylation and expression of PKA, PKC, STAT3, and NF-κB in cell lysates. b IFA detected the cellular location of STAT3 and NF-κB in hDPCs
