不确定细胞组织细胞增生症(ICH)和朗格汉斯细胞组织细胞增生症(LCH)是罕见的原因不明的组织细胞增生性疾病。然而,这两种肿瘤细胞在免疫表型上都有朗格汉斯细胞(LC)的一些特征,从而表达CD1a。最近的转录组分析表明,循环中的CD1c+髓系树突状细胞是LCH肿瘤细胞的潜在前体。LC表达CD1a和CD1c,但不表达CD1b。我们发现这两种肿瘤细胞都表达CD1c,但不表达CD1b,这与LC相似。此外,和LC一样,这两种肿瘤细胞都表达集落刺激因子1受体(CSF-1R)。考虑到IL-34/CSF-1R轴在LC的发生和存活中的重要作用,两种肿瘤细胞上的CSF-1R可能促进其在原位的存活和增殖。这些数据为ICH和LCH与LC具有共同的免疫表型特征这一事实提供了额外的证据。此外,我们假设ICH和LCH中的肿瘤细胞通过IL-34介导的CSF-1R信号存活和增殖。
Indeterminate cell histiocytosis (ICH) and Langerhans cell histiocytosis (LCH) are rare histiocyte proliferating disorders with unknown etiologies. However, both tumor cells immunophenotypically share some features of Langerhans cells (LC), thereby expressing CD1a. Recent transcriptome analysis revealed that circulating CD1c+myeloid dendritic cells are the potential precursor of LCH tumor cells. LC express CD1a as well as CD1c, but not CD1b. We discovered that both tumor cells express CD1c, but not CD1b, similar to LC. Moreover, like LC, both tumor cells express colony‐stimulating factor 1 receptor (CSF‐1R). Considering the crucial role of the interleukin (IL)‐34/CSF‐1R axis for the development and survival of LC, CSF‐1R on both tumor cells might facilitate their survival and proliferationin situ. These data provide additional evidence to support the fact that ICH and LCH share immunophenotypical features with LC. In addition, we hypothesized that tumor cells in ICH and LCH survive and proliferate through IL‐34‐mediated CSF‐1R signaling.
