WebCIBERSORTx uses a reference matrix of cell-specific expression and mathematical deconvolution to estimate cell-type abundances from bulk tissue transcriptomes. The leukocyte signature matrix (LM22), which consists of 22 hematopoietic lineages, is a well-characterized reference matrix based on the expression profiles of 547 genes.
WebApr 11, 2024 · CIBERSORTx has a predetermined set of signature genes defined for every immune cell type and their standard expression values known as the Lm22 matrix. Uploading your transcriptome data into the software, it is compared to the Lm22 matrix, and the percentage of immune cell fraction in every sample is determined. WebOct 8, 2024 · CIBERSORTx provides an empirical p-value to evaluate deconvolution performance. The p-value is calculated by comparing the resulting cell type fractions with fractions that would have been obtained by random chance .

We then sought more finely tuned methodologies to estimate immune cell proportions. We performed microenvironment deconvolution through the CIBERSORTx software based on the LM22 signature matrix (median RMSE: 0.73) and obtained the results described in Table 2.
WebJun 15, 2024 · We inferred the initial H via deconvolution using CIBERSORTx’s LM22 signature matrix. Since this H contains 22 cell types while our sample number and leave-one-out jackknife require the number of cell type not exceeding 9, we merged H into eight main cell types based on their abundances and similarities.
