dc.description.abstract | ABSTRACT
We quantified the collective impact of source partner HIV-1 RNA levels, human leukocyte antigen (HLA) alleles, and innate re-
sponses through Toll-like receptor (TLR) alleles on the HIV-1 set point. Data came from HIV-1 seroconverters in African HIV-1
serodiscordant couple cohorts. Linear regression was used to determine associations with set point and
R

to estimate variation
explained by covariates. The strongest predictors of set point were HLA alleles (B*53:01, B*14:01, and B*27:03) and plasma
HIV-1 levels of the transmitting partner, which explained 13% and 10% of variation in set point, respectively. HLA-A concor-
dance between partners and TLR polymorphisms (
TLR2
rs3804100 and
TLR7
rs179012) also were associated with set point, ex-
plaining 6% and 5% of the variation, respectively. Overall, these factors and genital factors of the transmitter (i.e., male circum-
cision, bacterial vaginosis, and use of acyclovir) explained 46% of variation in set point. We found that both innate and adaptive
immune responses, together with plasma HIV-1 levels of the transmitting partner, explain almost half of the variation in viral
load set point | en_US |
