ABSTRACT The orphan nuclear receptor, retinoic acid receptor-related orphan nuclear receptor γt (RORγt), is required for the development and pathogenic function of interleukin-17A-secreting CD4+ T helper type 17 (Th17) cells. Whereas small molecule RORγt antagonists impair Th17 cell development and attenuate autoimmune inflammation in vivo, the broader effects of these inhibitors on RORγt-dependent gene expressionRead More
Oxysterols are agonist ligands of RORγt and drive Th17 cell differentiation
ABSTRACT The RAR-related orphan receptor gamma t (RORγt) is a nuclear receptor required for generating IL-17–producing CD4+ Th17 T cells, which are essential in host defense and may play key pathogenic roles in autoimmune diseases. Oxysterols elicit profound effects on immune and inflammatory responses as well as on cholesterol and lipid metabolism. Here, we describe the identification of several naturally occurringRead More
