Abstract
We have shown, both in vitro and in vivo, that NF-κB blockade on DCs by andrographolide or rosiglitazone can significantly enhance the tolerogenic capacity of DCs. Furthermore, we have observed that expression ratio of the activating FcγRIII or the inhibitory FcγRIIb is determinant for the tolero...
