參考文獻:Quantifying tumor-infiltrating immune cells from transcriptomics data
從轉(zhuǎn)錄組學(xué)數(shù)據(jù)中量化腫瘤浸潤性免疫細胞
這是一篇關(guān)于免疫量化的綜述,列舉了十多種量化免疫浸潤的方法，部分方法可以使用CellMix 包的一些函數(shù)實現(xiàn)
Features of the computational tools for the quantification of tumor-infiltrating immune cells from transcriptomics data considered in this review: tool or function name, algorithm type** (M?=?marker genes, P?=?partial deconvolution, C?=?complete deconvolution)**, main method, cell types quantified using the embedded gene sets or signature profiles, code availability, name of the method in the CellMix package [9], reference publication
- M?=?marker genes 基于特征基因
- P?=?partial deconvolution 基于部分去卷積
- C?=?complete deconvolution) 完全去卷積
