Interleukin-21 inhibits dendritic cell activation and maturation.
Interleukin 21 (IL-21) is a newly described cytokine with homology to IL-4 and IL-15. They belong to a cytokine family that uses the common gamma chain for signaling but also have their private high-affinity receptors. Since it is well known that IL-4 modulates differentiation and activation of dendritic cells (DCs), we analyzed effects of IL-21 compared with IL-15 on DC differentiation, matura...
متن کاملGSK-3 mediates differentiation and activation of proinflammatory dendritic cells.
The key components of the intracellular molecular network required for the expression of a specific function of dendritic cells (DCs) are as yet undefined. Using an in vitro model of human monocyte-derived DC differentiation, this study investigates the role of glycogen synthase kinase 3 (GSK-3), a multifunctional enzyme critical for cellular differentiation, apoptosis, self-renewal, and motili...
متن کاملProstaglandin E2 induces the final maturation of IL-12-deficient CD1a+CD83+ dendritic cells: the levels of IL-12 are determined during the final dendritic cell maturation and are resistant to further modulation.
Activation of immature dendritic cells (DC) in peripheral tissues induces their migration to lymph nodes and their maturation into CD83+ DC, which are able to prime naive T cells. The inflammatory cytokines IL-1beta and TNF-alpha induce mature DC, which can secrete IL-12 and promote the development of Th0/Th1-biased cells. DC maturation factors with a Th2-promoting function have not been descri...
متن کاملInhibition of maturation and function of dendritic cells by intravenous immunoglobulin.
Normal immunoglobulin G for therapeutic use (intravenous immunoglobulin [IVIg]) is used in an increasing number of immune-mediated conditions, including acute and chronic/relapsing autoimmune diseases, transplantation, and systemic inflammatory disorders. Several mutually nonexclusive mechanisms of action account for the immunoregulatory effects of IVIg. Although IVIg inhibits T-cell proliferat...
متن کاملHeme oxygenase-1 expression inhibits dendritic cell maturation and proinflammatory function but conserves IL-10 expression.
Heme oxygenase-1 (HO-1) is an intracellular enzyme that degrades heme and inhibits immune responses and inflammation in vivo. In most cell types, HO-1 is inducible by inflammatory stimuli and oxidative stress. Here we demonstrate that human monocyte-derived immature dendritic cells (iDCs) and several but not all freshly isolated rat splenic DC subsets and rat bone marrow-derived iDCs, spontaneo...
