CosMx™
タンパク質アッセイ
高解像度の空間プロテオミクス解析
CosMx™プロテインアッセイは、1枚のFFPE(Formalin-Fixed Paraffin-Embedded)スライドから最大68種のタンパク質を空間的なコンテキストを持つシングルセルの解像度で高多重解析することができます。CosMxプロテインアッセイは、従来の免疫組織化学および免疫蛍光法と比較して、組織断片のバイアスのない空間プロテオミクス解析を提供します。すべてのCosMxプロテインアッセイは多重解析に使用するために検証されており、アッセイのパフォーマンスのトラブルシューティングに時間を費やすことなく、興味のある生物学に焦点を当てることができます。

Exploring Markers of Exhausted CD8 T Cells to Predict Response to Immune Checkpoint Inhibitor Therapy for Hepatocellular Carcinoma
Background: Reversal of CD8 T-cell exhaustion was considered a major antitumor mechanism of anti-programmed cell death-1 (PD-1)/ anti-programmed death ligand-1 (PD-L1)-based immune checkpoint inhibitor (ICI) therapy. Objectives: The aim of this study was to identify markers of T-cell exhaustion that is best associated with ICI treatment efficacy for advanced hepatocellular carcinoma (HCC).
Discovery of CD80 and CD86 as recent activation markers on regulatory T cells by protein-RNA single-cell analysis
Background: Traditionally, the transcriptomic and proteomic characterisation of CD4+ T cells at the single-cell level has been performed by two largely exclusive types of technologies: single-cell RNA sequencing (scRNA-seq) and antibody-based cytometry. Here, we present a multi-omics approach allowing the simultaneous targeted quantification of mRNA and protein expression in single cells and investigate its performance to dissect the heterogeneity of human immune cell populations.
MiR130b from Schlafen4+ MDSCs stimulates epithelial proliferation and correlates with preneoplastic changes prior to gastric cancer
The myeloid differentiation factor Schlafen4 (Slfn4) marks a subset of myeloid-derived suppressor cells (MDSCs) in the stomach during Helicobacter-induced spasmolytic polypeptide-expressing metaplasia (SPEM). Objective: To identify the gene products expressed by Slfn4+-MDSCs and to determine how they promote SPEM.
