Molecular mechanism of regulating tat protein expression of pingganjiedu TCM in the treatment of AIDS based on network pharmacology.

AIDS is a serious disease with impaired immune function caused by human immunodeficiency virus (HIV) infection. The treatment of AIDS has always been the focus of global scientific research, and Tat protein is a key regulatory protein in the process of HIV infection. Its high expression is closely related to virus replication, disease progression, etc. The aim of this study is to explore the molecular mechanism of regulating Tat protein expression by using network pharmacology based traditional Chinese medicine for calming the liver and detoxifying. 129 AIDS patients were enrolled in the study and randomly divided into HAART combined with PGJDP treatment and HAART alone treatment groups. The virological response rate, immunological response status (CD4 + T cell level, CD4/CD8) and incidence of abnormal liver function were observed before and 48 weeks after treatment. Using the TCMSP database to obtain the chemical components and targets of the main traditional Chinese medicine components in PGJDP, clinical results indicate that the combination of HAART and PGJDP treatment can improve the virological response rate (P > 0.05); Increase the number of CD4 + T lymphocytes (P > 0.05); Significantly increased CD4/CD8 ratio (P < 0.01); Simultaneously, it significantly reduced the incidence of liver dysfunction (P < 0.01). After screening and analysis, the Chinese herbal medicine for calming liver and detoxifying has the potential to significantly regulate the expression of Tat protein. These Chinese herbal compounds can reduce the expression of Tat protein by affecting key pathways and regulating the expression of related genes, which has potential therapeutic effects on the treatment of AIDS.
