High impact information on Il1rl2

• IL-18Rbeta expression was significantly increased in response to treatment of mixed glia with bacterial lipopolysaccharide (LPS) in vitro, whereas expression of IL-1Rrp2 and TIGIRR1 was reduced [1].
• Messenger RNA for IL-1Rrp2 was not detected in primary neurones by RT-PCR, but significant constitutive expression was found in mixed glial cells, particularly in astrocytes and microglia, which was strongly decreased by exposure to bacterial lipopolysaccharide (LPS) [2].
• These results demonstrate that glial cells may be a target for the new ligand IL-1F9, since high expression of IL-1Rrp2 mRNA was detected in these cells [2].
• Human synovial fibroblasts (hSFs) and human articular chondrocytes (hACs) expressed the IL-1F8 receptor (IL-1Rrp2) and produced pro-inflammatory mediators in response to recombinant IL-1F8 [3].

Anatomical context of Il1rl2

• Furthermore, IL-18Rbeta, IL-1Rrp2, but not TIGIRR1 expression, was increased in the brain in vivo in response to peripheral administration of LPS or middle cerebral artery occlusion (MCA) [1].

Other interactions of Il1rl2

• The aim of the present study was therefore to investigate expression of IL-1Rrp2 and to determine if IL-1F9 induces known IL-1 signaling pathways in the different cell types of the mouse brain in culture [2].
