Abstract:
Objective To investigate the correlation between the human chemokine type 1 chemokine ligand 3 (CCL3L1) and chemokine ligand 4 (CCL4L) gene expression and the immune reconstitution of acquired immunodeficiency syndrome (AIDS) patients after antiretroviral therapy.Methods The gene copy numbers of CCL3L1 and CCL4L were detected by real time polymerase chain reaction in 217 AIDS patients before antiretroviral therapy.And the correlation between CCL3L1 and CCL4L gene copy numbers and the level of CD4+ and CD8+ T lymphocytes were analyzed.The changes of CD4+ and CD8+ T lymphocytes were defined as mean change value per month after 48 months treatment.The change rates of CD4+ and CD8+ T lymphocytes were defined as the logarithm of the ratio of the value after 48 month to that at baseline.Comparison between groups was conducted using analysis of variance.Results The median of gene copy numbers of CCL3L1 and CCL4L were 2 (range:0-8) and 3 (range:0-7),respectively.After antiviral treatment,there were significantly different changes of CD8+ T lymphocyte level (F=3.054,P＜0.05) and change rate of CD4+/CD8+ (F=3.520,P＜0.05) among groups of high (gene copy 4-8),median (gene copy 2-3) and low (gene copy 0-1) CCL3L1 gene copy numbers.The changes of CD8+ T lymphocyte levels (P=0.023) and change rates (P=0.038) in high and low CCL3L1 gene copy groups were both significantly different.There were significant differents changes rate of ratio of CD4+/CD8+ T lymphocyte among high and median (P=0.010),high and low CCL3L1 gene copy numbers (F=4.397,P＜0.05).The significant difference of the change rates of CD4+/CD8+ were found between the gene copy 3 group and gene copy 4-7 group CCL4L (P=0.005) and between the gene copy 4-7 group and gene copy 0-2 group of CCL4L (P=0.030).The change ratio of CD4+/CD8+ T lymphocytes increased with the increase of copy numbers of CCL4L gene.Conclusions The gene expressions of CCL3L1 and CCL4L might be associated with the ability of immune reconstitution of AIDS patients after antiretroviral therapy.
