Project description:It is important to understand how, if at all, antiretroviral prophylaxis with tenofovir disoproxil fumarate (TDF) alone or TDF in conjunction with emtricitabine (FTC) affects gene expression. To ask this question, we used cryopreserved peripheral blood mononuclear cells (PBMC) from women enrolled in the Genital Mucosal Substudy (GMS) [1] of the Partners PrEP Study (NCT02621242) [2]. Partners PrEP was a randomized Phase III trial of oral TDF or TDF/FTC compared to placebo, which showed that either active drug was effective at protecting against HIV-1 infection. Samples were unpaired, with one sample per person, after 24-36 months of oral treatment with placebo, TDF, or TDF/FTC. Treatment adherence was based on plasma TDF concentrations. Covariates included Nugent scores (for bacterial vaginosis), HSV-2 serology, age, and birth control method. Levels of natural and synthetic hormones (medroxyprogesterone acetate [MPA], estradiol [E2], ethinyl estradiol [EE2], levonorgestrel [LNG], etonogestrel [ENG], progesterone [P4], and norethisterone enanthate [NET-EN]) were measured in the serum. 1.

Samples were taken after 24-36 months of oral treatment with placebo, TDF, or TDF/FTC or two months after discontinuation. Treatment adherence was based on plasma TDF concentrations. Covariates included Nugent scores (for bacterial vaginosis), HSV-2 serology, age, and birth control method. Levels of natural and synthetic hormones (medroxyprogesterone acetate [MPA], estradiol [E2], ethinyl estradiol [EE2], levonorgestrel [LNG], etonogestrel [ENG], progesterone [P4], and norethisterone enanthate [NET-EN]) were measured in the serum. 1.

Project description:We aim to characterize HIV and HCV coinfected patient response to combined antiretroviral therapy through genome-wide expression profiling of patients' periperhal blood mononuclear cells before and after treatment initiation (baseline and 24 weeks). Individuals with frank cirrhosis were excluded from the study. We used Affymetrix PrimeView arrays to quantify baseline transcriptomic characteristics and changes in the transcriptome following treatment. Gene expression changes were analyzed based on the change in expression of each transcript per patient. Mononuclear cells were purified from peripheral blood samples of 8 patients with HIV and HCV coinfection at baseline and after 24 weeks of combined antiretroviral therapy. Genes from whole blood RNA was measured via Affymetrix PrimeView microarrays.

Project description:It is important to understand how, if at all, antiretroviral prophylaxis with tenofovir disoproxil fumarate (TDF) alone or TDF in conjunction with emtricitabine (FTC) affects gene expression. To ask this question, we used vaginal biopsies from women enrolled in the Genital Mucosal Substudy (GMS) [1] of the Partners PrEP Study (NCT02621242) [2]. Partners PrEP was a randomized Phase III trial of oral TDF or TDF/FTC compared to placebo, which showed that either active drug was effective at protecting against HIV-1 infection.

Project description:It is important to understand how, if at all, antiretroviral prophylaxis with tenofovir disoproxil fumarate (TDF) alone or TDF in conjunction with emtricitabine (FTC) affects gene expression. To ask this question, we used cervicovaginal biopsies from women enrolled in the Genital Mucosal Substudy (GMS) [1] of the Partners PrEP Study (NCT02621242) [2]. Partners PrEP was a randomized Phase III trial of oral TDF or TDF/FTC compared to placebo, which showed that either active drug was effective at protecting against HIV-1 infection. Samples were taken after 24-36 months of oral treatment with placebo, TDF, or TDF/FTC or two months after discontinuation. Treatment adherence was based on plasma TDF concentrations. The samples in this series are thought to be endocervical biopsies on the basis of their gene expression. Covariates included Nugent scores (for bacterial vaginosis), HSV-2 serology, age, and birth control method. Levels of natural and synthetic hormones (medroxyprogesterone acetate [MPA], estradiol [E2], ethinyl estradiol [EE2], levonorgestrel [LNG], etonogestrel [ENG], progesterone [P4], and norethisterone enanthate [NET-EN]) were measured in the serum. 1.
