应用不同的技术来监测疾病活动和治疗效果对于多发性硬化症等复杂疾病至关重要。结合目前的分析与流式细胞术可以创建一个强大的工具,这样的分析。CD 74(MHC II类不变链)的细胞表面表达水平是一种潜在的疾病生物标志物,其可以通过FACS分析来监测,以评估疾病进展和部分MHC II类构建体在治疗MS中的临床功效。这些构建体可以结合并下调单核细胞上的CD 74细胞表面表达并抑制巨噬细胞迁移抑制因子(MIF)作用,可以逆转EAE的临床和组织学体征。部分II类构建体的这些性质与用于监测作为疾病活动/进展的可能生物标志物和作为治疗应答标志物的CD 74表达的流式细胞术方法高度相容。
Applying different technologies to monitor disease activity and treatment efficacy are essential in a complex disease such as multiple sclerosis. Combining current assays with flow cytometry could create a powerful tool for such analyses. The cell surface expression level of CD74, the MHC class II invariant chain, is a potential disease biomarker that could be monitored by FACS analysis in order to assess disease progression and the clinical efficacy of partial MHC class II constructs in treating MS. These constructs, which can bind to and down-regulate CD74 cell-surface expression on monocytes and inhibit macrophage migration inhibitory factor (MIF) effects, can reverse clinical and histological signs of EAE. These properties of partial class II constructs are highly compatible with a flow cytometry approach for monitoring CD74 expression as a possible biomarker for disease activity/progression and as a treatment response marker.
