Abstract

The mechanisms of pathogenesis driving alpha-gal syndrome (AGS) are not fully understood. Differences in immune gene expression between AGS individuals and non-allergic controls may illuminate molecular pathways and targets critical for AGS development. We performed immune expression profiling with RNA from the peripheral blood mononuclear cells (PBMCs) of seven controls, 15 AGS participants, and two participants sensitized but not allergic to alpha-gal using the NanoString nCounter PanCancer immune profiling panel, which includes 770 genes from 14 different cell types. The top differentially expressed genes (DEG) between AGS subjects and controls included transcription factors regulating immune gene expression, such as the NFκB pathway (), antigen presentation molecules, type 2/allergic immune responses, itch, and allergic dermatitis. The differential expression of genes linked to T and B cell function was also identified, including transcription factor , markers of antigen experience () and memory (), chemokine receptors (), and regulators of B-cell proliferation, cell cycle entry and immunoglobulin production (). The PBMCs from AGS subjects also had increased TNF and IFN-gamma mRNA expression compared to controls. AGS is associated with a distinct gene expression profile in circulating PBMCs. DEGs related to antigen presentation, antigen-experienced T-cells, and type 2 immune responses may promote the development of alpha-gal specific IgE and the maintenance of AGS.

摘要

α-半乳糖苷综合征(AGS)的发病机制尚不完全清楚。AGS 个体与非过敏对照者之间免疫基因表达的差异可能阐明对 AGS 发展至关重要的分子途径和靶点。我们使用 NanoString nCounter PanCancer 免疫基因表达谱面板,对来自 7 名对照者、15 名 AGS 参与者和 2 名对 α-半乳糖过敏但不过敏的参与者的外周血单核细胞(PBMC)进行免疫基因表达谱分析,该面板包含来自 14 种不同细胞类型的 770 个基因。AGS 患者与对照组之间差异表达的基因(DEG)包括调节免疫基因表达的转录因子,如 NFκB 途径()、抗原呈递分子、2/过敏免疫反应、瘙痒和过敏性皮炎。还鉴定了与 T 和 B 细胞功能相关的基因的差异表达,包括转录因子 、抗原经历的标志物()和记忆()、趋化因子受体()以及 B 细胞增殖、细胞周期进入和免疫球蛋白产生的调节剂()。与对照组相比,AGS 患者的 PBMCs 中 TNF 和 IFN-γ mRNA 的表达也增加了。AGS 与循环 PBMC 中独特的基因表达谱相关。与抗原呈递、抗原经历的 T 细胞和 2 型免疫反应相关的 DEG 可能促进 α-半乳糖特异性 IgE 的产生和 AGS 的维持。
