Problems solved by technology

To sum up, the analysis technology of cell communication is very important and widely used, but there is no comprehensive and in-depth study of the molecular mechanism of intercellular communication, and the data results are displayed in various graphical forms. Therefore, the present invention provides a cell communication analysis method, which can be applied to further cell communication analysis of single-cell transcriptome sequencing data. The analysis process is efficient, the analysis content is comprehensive, and the analysis results are visualized.

Abstract

The invention discloses a cell communication analysis method and system. The method comprises cell communication prediction and ligand-target gene regulation prediction. Cell communication predictioncomprises analysis of expression abundance of a ligand-receptor pair, analysis of the number of ligand-receptor pairs, analysis of the number of significantly enriched ligand-receptor pairs and construction of a cell interaction network diagram. The ligand-target gene regulation and control prediction comprises ligand activity analysis and ligand-target gene regulation and control potential analysis; the cell communication analysis method mainly comprises the following steps: describing an incidence relation among cells, constructing a cell communication network by utilizing CellphoneDB software based on a single-cell gene expression quantity matrix, and analyzing ligand activity and the regulation potential of a ligand on a target gene by utilizing NicheNet software based on a ligand-target gene expression relation. Various graphical results are displayed, so that the incidence relation between cells is convenient to research; a new basic scientific research idea can be provided for revealing a certain cell behavior and deeply analyzing a cell communication result.

Description

Technical field [0001] The present invention relates to the field of biological information analysis, and more particularly to a cell communication analysis method and system. Background technique [0002] Complex extracellular reactions begin with the binding of the ligand and its receptor and activation of a particular cellular signaling path, therefore, understanding and plotting the interaction of these ligands and receptors is to understand cellular behavior and the basis for adjacent cellular reactions. Many foundations of research mechanism research. However, the interaction mechanism within the organizational cell is very complicated, involving a variety of cells, as well as potential for thousands of ligand-receptor relationships, screening with traditional molecular biology methods, relying on researchers' experience, it is difficult to directly Lock the key cell interaction relationship. If the person is not accurate, the function verifies that there is a false positiv...
