Objective To analyze the biological functions and molecular networks of differentially expressed proteins in anti-asthma acupuncture and explore the application of bioinformatic methods to and ideas for acupuncture research. Methods PANTHER classification system, Pathway Interaction Database (PID) and Ingenuity Pathway Analysis (IPA) software were used for molecular biological function annotation of differentially expressed proteins in anti-asthma acupuncture and analyses of signaling pathways, protein-protein interactions and molecular regulatory networks. Results Several differentially expressed proteins in anti-asthma acupuncture were closely related to immune system function and involved in biological pathways including RhoA signaling pathway, Toll-like receptor signaling pathway, eosinophils Ccr3 signaling pathway and T cell IL-2R beta activation pathway. They produced an immunoregulatory effect by modulating downstream cytokines and influencing CD4 molecule function). Conclusion Immune-related molecular pathways and regulation targets involved in the anti-asthma effect of acupuncture are obtained by bioinformatic analysis of differentially expressed proteins in anti-asthma acupuncture, which provides a basis for further research on the immune-related molecular mechanisms of acupuncture treatment for asthma.
