Does delta-opioid receptor activation promote mesenchymal stem cell survival via PKC/STAT3 signaling pathway?
Taken together, the results indicate that DOR plays a critical role in MSC survival upon exposure to actinomycin D through activation of protein kinase C and its downstream signaling molecules STAT3 and Mcl-1. DOR may be a novel therapeutic target for stem cell survival during cell-based therapy.
A reduction in CD70, GARP, IDO, IL17B (IL-20), and IL17E (IL-25), coupled with increases in RORγT, ARNT, FoxP3, and IL17C (IL-21) following thalidomide treatment, opens the door to understanding the complexity of the immunomodulatory drug thalidomide, which can operate as an anti-inflammatory while simultaneously stimulating cell-mediated immunity (CMI). We conclude that TH17 is involved in the immunopathogenesis of ENL and that thalidomide suppresses inflammatory components of TH17, while enhancing other components of TH17 that are potentially involved in CMI.
