Although studies have identified that dendritic cells (DCs) are important for induction of antigen-specific tolerance, the requirements for generating tolerogenic DCs are yet to be elucidated. Recently, it has been demonstrated the modulation of two signaling pathways, Notch and nuclear factor KB (NF-KB) can render DCs tolerogenic. The studies documented here examine (1) whether immature DCs over-expressing Notch-related molecules (Jagged-I, Delta-like-I (Dll-I), Lunatic Fringe (Ung) , and Manic Fringe (Mfng)) act as immunoregulatory DCs and promote allograft survival; and (2) whether DCs deficient in NF-KB signaling inhibit the alloreactive T cell response and promote allograft survival ... Although the potential for Notch signaling to promote alloantigen-specific tolerance remains unresolved, these studies suggest that inhibition of NF-KB signaling in DCs represent a potential approach for promoting allograft survival.en-AUTransplantation, Notch, NF-kB, allogeneic response, dendritic cells, BAY11-7082200610.25911/5d7a27c0c1d62
