Abstract

OBJECTIVE:

To discuss the drug intervention in diversity changes of TCRVbeta gene in AIDS patients with incomplete immune reconstitution.

METHOD:

PBMCs were isolated from 37 cases of AIDS patients failure to immune reconstitution before and after treatment with Immune 2 and 15 cases of HIV negative healthy donors. The human gene TCRVbeta CDR3 diversity quantitative detection reagent box were used, and mapped the distribution of gene scanning and calculated different CDR3 fragme of each Vbeta family size.

RESULT:

(1) Gaussian distribution of TCRVbeta families in patients with incomplete immune reconstitution after one year of HAART, had been broken with the occurrence of the offset TCR lineage. After six months of treatment of traditional Chinese medicine combined HAART, the TCR lineage has been partially restored. (2) Evaluated by the D (distance) value calculated by a quantitative analysis software which the kit provides, there were no significant difference in D value change between the two groups, but with traditional Chinese medicine can reduce the data variability. (3) CD4+ T cell counts had a significant correlation (r = -0.772, P = 0.000) with TCRVbeta genetic diversity.

CONCLUSION:

Study of the mechanism showed oligoclonal of TCRVbeta family can get recovery in some degrees after treated by Immune 2 plus HAART, suggesting that the medicine may promote T-cell receptor gene rearrangement, helping immune cells to effectively identify the virus to reduce T-cell apoptosis.
