PG - 449-457 LID - S1043-6618(16)30873-8 [pii] LID - 10.1016/j.phrs.2016.09.001 [doi] AB - Dendritic cells (DCs) are critical regulators of adaptive immune responses. DCs can elicit primary T cell responses at low DC:T cell ratios through their expression of high levels of antigen-presenting molecules and costimulatory molecules. DCs are important for induction of functionally diverse T cell subsets such as CD4(+) T helper (Th)1 and Th17 cells and effector CD8(+) T cells able to reside in epithelial tissues. Recent studies begin illuminating the underlying mechanism by which DCs regulate specialized T cell subsets. DCs are composed of subsets that differ in their phenotype, localization and function. DCs expressing high levels of DLL4 (DLL4(+) DCs), which is a member of Notch ligand family, are newly discovered cells that have greater ability than DLL4(-) DCs to promote the generation of Th1 and Th17 CD4(+) T cells. DLL4 derived from DLL4(+) DCs is also important for promoting the differentiation and expansion of effector CD8(+) T cells. Experimental studies have demonstrated that selective deletion of DLL4 in DCs causes impaired antitumor immunity. In contrast, blocking DLL4 leads to dramatic reduction of inflammatory T cell responses and their-mediated tissue damage. We will discuss emerging functional specialization within the DLL4(+) DC compartment, DLL4(+) DC biology and the impact of pharmacological modulation of DLL4 to control inflammatory disorders.
