Therefore, the release of sRAGE may influence the regulation of RAGE-mediated functions in inflammatory events.
In order to identify relevant transcription factors implicated in the regulation of Rage-dependent genes we performed an in silico promoter analysis.
The proportion and production of the soluble form of the endogenous receptor may therefore influence the regulation of RAGE-mediated functions in various tissues and inflammatory conditions, including RA.
In the liver, a significant up-regulation of RAGE was observed in hepatocytes and bile ducts and vessels in portal tracts.
These results together indicated that HMGB1 could induce an intimate cellular interplay between monocytes and T-cells in PBMCs through the stimulation and up-regulation of RAGE and other adhesive molecules on monocytes.
Incubation of infected DCs with HMGB1 induced similar down-regulation of RAGE (Fig. 3d).
After 2 h of coculture with aNK cells, DCs showed an up-regulation of RAGE expression, followed by a down-regulation at 24 h (Fig. 3e).
Following incubation of iDCs with 1 µg/ml of HMGB1, down-regulation of RAGE was observed, strongly suggesting that this receptor was used by these cells (Fig. 3d).
We observed significant down-regulation of RAGE gene expression after PACAP treatment.
Moreover, FR171113 significantly prevented the plasma-elicited up-regulation of RAGE, MCP-1 and ICAM-1 mRNA levels in HUVECs.
The up-regulation of RAGE is one of the functions of IL-17 for modulating the inflammatory condition.
