The cytokine IL-18 acts on the CNS both in physiological and pathological conditions. Its action occurs through the heterodimeric receptor IL-18Ralpha\beta. To better understand IL-18 central effects, we investigated in the mouse brain the distribution of two IL-18Ralpha transcripts, a full length and an isoform lacking the intracellular domain hypothesized to be a decoy receptor. Both isoforms were expressed in neurons throughout the brain primarily with overlapping distribution but also with some unique pattern. These data suggest that IL-18 may modulate neuronal functions and that its action may be regulated through expression of a decoy receptor.
细胞因子白细胞介素18（IL-18）在生理和病理条件下均可作用于中枢神经系统。其作用通过异二聚体受体IL-18Rαβ发生。为了更好地理解IL-18的中枢效应，我们在小鼠脑中研究了两种IL-18Rα转录本的分布，一种是全长转录本，另一种是缺少假定为诱饵受体的细胞内结构域的同种型。两种同种型主要在全脑的神经元中表达，分布重叠，但也有一些独特的模式。这些数据表明，IL-18可能调节神经元功能，并且其作用可能通过诱饵受体的表达来调节。
