Abstract:
The HIV susceptibility and resistance alleles in the HLA genes were determined by investigating the distribution characteristics of the HLA alleles (A,B,and DRB1) in HIV-infected individuals of the Han population in Hubei,and by comparing these alleles with HIV-negative individuals from the same area.A cohort of 424 HIV-1 infected individuals were chosen as study subjects,and 836 HIV-negative healthy subjects from the same area served as the control population.HLA-A,B,and DRB 1 allele typing was performed using polymemse chain reaction-sequence-specific oligonucleotide probes (PCR-SSOP) and polymerase chain reaction-sequencing based typing (PCR-SBT) techniques.Arlequin ver3.0 was used to analyze the allele and haplotype frequencies of HLA-A,B,and DRB l,whereas Epi Info 7 and SPSS18.0 was used to analyze the differences in the HLA alleles between the HIV-1 positive and HIV-1 negative groups.A*02:03,DRB1*01:01,and DRB1*15:01 alleles and their haplotypes as well as the HLA_Bw4-Bw6 hybrid showed a protective effect on HIV-1 infection.After adjusting for confounding factors such as age and sex,multivariate logistic regression analysis revealed that B* 15:02G,DRB 1*01:01,and DRB 1 * 15:01 subtypes were the resistance genes of HIV-1 infection,while B * 13:01 might increase susceptibility to HIV-1 infection.The correlation between A*02:06 and B*15:01G subtypes and HIV-1 susceptibility was independent of the age and sex of the host.This study demonstrated the influence of genetic factors in humans such as HLA polymorphism on individuals to resist HIV-1 infection.Association studies of HLA polymorphism,susceptibility/resistance to HIV-1 infection,and hosts' genetic background are of significant importance for research on HIV-1 pathogenesis and vaccine design.
