UnknownT Cell Responses against Mycobacterial Lipids and Proteins Are Poorly Correlated in South African Adolescents.
Human T cells are activated by both peptide and nonpeptide Ags produced by Mycobacterium tuberculosis. T cells recognize cell wall lipids bound to CD1 molecules, but effector functions of CD1-reactive T cells have not been systematically assessed in M. tuberculosis-infected humans. It is also not kn...

UnknownChanges in glomerular kidney function among HIV-1-uninfected men and women receiving emtricitabine-tenofovir disoproxil fumarate preexposure prophylaxis: a randomized clinical trial.

Importance

Tenofovir disoproxil fumarate (TDF) use has been associated with declines in the estimated glomerular filtration rate (eGFR) when used as part of antiretroviral treatment by persons with human immunodeficiency virus (HIV) type 1, but limited data are available for risk when used a...

TranscriptomicsEx vivo effects of Tenofovir on four vaginal epithelial cell lines
In MTN-007, a phase 1, randomized, double-blinded rectal microbicide trial, we used systems genomics/proteomics to determine the effect of tenofovir 1% gel, nonoxynol-9 2% gel, placebo gel or no treatment on rectal biopsies taken at baseline, after one application or after seven daily applications (...

TranscriptomicsSystems analysis of the Merck Ad5/HIV vaccine reveals robust induction of a core innate immune gene network: in vitro analysis
Here we applied a systems approach to define human innate immune signatures following MRKAd5/HIV immunization and to analyze the effects of pre-existing Ad5 immunity. To determine whether vaccine-induced changes could be ascribed to cell-intrinsic responses rather than cell population fluxes, fresh ...

TranscriptomicsSystems analysis of the Merck Ad5/HIV vaccine reveals robust induction of a core innate immune gene network: in vivo analysis
Here we applied a systems approach to define human innate immune signatures following MRKAd5/HIV immunization and to analyze the effects of pre-existing Ad5 immunity. We defined the global early immune response to MRKAd5/HIV by profiling the PBMC transcriptomes from seven Ad5Neg individuals pre- and...

UnknownTrivalent mosaic or consensus HIV immunogens prime humoral and broader cellular immune responses in adults.
BACKGROUNDMosaic and consensus HIV-1 immunogens provide two distinct approaches to elicit greater breadth of coverage against globally circulating HIV-1 and have shown improved immunologic breadth in nonhuman primate models.METHODSThis double-blind randomized trial enrolled 105 healthy HIV-uninfecte...

UnknownProbing Dermal Immunity to Mycobacteria through a Controlled Human Infection Model.
Cutaneous mycobacterial infections cause substantial morbidity and are challenging to diagnose and treat. An improved understanding of the dermal immune response to mycobacteria may inspire new therapeutic approaches. We conducted a controlled human infection study with 10 participants who received ...

TranscriptomicsMerck Ad5/HIV induces broad innate immune activation that predicts CD8+ T-cell responses but is attenuated by preexisting Ad5 immunity.
This SuperSeries is composed of the following subset Series: GSE22768: Systems analysis of the Merck Ad5/HIV vaccine reveals robust induction of a core innate immune gene network: in vivo analysis GSE22769: Systems analysis of the Merck Ad5/HIV vaccine reveals robust induction of a core innate immun...

UnknownHIV-specific humoral responses benefit from stronger prime in phase Ib clinical trial.
BACKGROUND. Vector prime-boost immunization strategies induce strong cellular and humoral immune responses. We examined the priming dose and administration order of heterologous vectors in HIV Vaccine Trials Network 078 (HVTN 078), a randomized, double-blind phase Ib clinical trial to evaluate the s...

UnknownA phase IIA randomized clinical trial of a multiclade HIV-1 DNA prime followed by a multiclade rAd5 HIV-1 vaccine boost in healthy adults (HVTN204).

Background

The safety and immunogenicity of a vaccine regimen consisting of a 6-plasmid HIV-1 DNA prime (envA, envB, envC, gagB, polB, nefB) boosted by a recombinant adenovirus serotype-5 (rAd5) HIV-1 with matching inserts was evaluated in HIV-seronegative participants from South Africa, Uni...
