细胞类型的组成变化是生物过程的主要驱动力。由于数据的组成性和低样本量,通过单细胞实验检测它们是困难的。我们介绍了scCODA(https://github.com/theislab/scCODA),这是一种解决这些问题的贝叶斯模型,可以研究疾病和其他刺激中的复杂细胞类型效应。scCODA表现出优异的检测性能,同时可靠地控制错误的发现,并确定实验验证的细胞类型的变化,在原始分析中错过了。细胞类型的不平衡和丢失是许多疾病的标志。尽管如此,量化scRNAseq数据中的组成变化仍然具有挑战性。在这里,作者提出了scCODA,这是一种贝叶斯模型,用于评估scRNA-seq数据中的细胞类型组成。
Compositional changes of cell types are main drivers of biological processes. Their detection through single-cell experiments is difficult due to the compositionality of the data and low sample sizes. We introduce scCODA (https://github.com/theislab/scCODA), a Bayesian model addressing these issues enabling the study of complex cell type effects in disease, and other stimuli. scCODA demonstrated excellent detection performance, while reliably controlling for false discoveries, and identified experimentally verified cell type changes that were missed in original analyses. Imbalance and loss of cell types is a hallmark in many diseases. Still, quantifying compositional changes in scRNAseq data remains challenging. Here the authors present scCODA, a Bayesian model to assess cell type compositions in scRNA-seq data.
