TranscriptomicsTranscriptional profiling of experimental CD8+ lymphocyte depletion in rhesus macaques infected with SIVmac239
CD8+ T-cells inhibit virus replication in SIV-infected rhesus macaques (RM). However, it is unclear to what extent the viral suppression mediated by CD8+ T-cells reflects direct killing of infected cells as opposed to indirect, non-cytolytic mechanisms. In this study, we used functional genomics to ...

MetabolomicsFeatures of acute COVID-19 associated with post-acute sequelae of SARS-CoV-2 phenotypes: results from the IMPACC study
Post-acute sequelae of SARS-CoV-2 (PASC) is a significant public health concern. We describe Patient Reported Outcomes (PROs) on 590 participants prospectively assessed from hospital admission for COVID-19 through one year after discharge. Modeling identified 4 PRO clusters based on reported deficit...

TranscriptomicsMicroarray analysis of whole-blood in HIV-infected Viremic Non Progressor patients
We assessed correlates of protection from disease progression in a rare subset of HIV-infected individuals, viremic non-progressors (VNPs). These individuals have high viral load for several years, but in contrast to the majority of infected individuals, they do not progress to AIDS. Here we found t...

TranscriptomicsCharacterization of CD57+PD1- CD4 T cells
We have identified a CD57+PD1- CD4 T cell phenotype at the time of transplantation that strongly correlates with subsequesnt development of belatacept-resistant rejection. In this study, we used microarray to determine which genes were upregulated in CD57+ compared to CD57- CD4 T cells. Peripheral b...

TranscriptomicsACTG A5258 Clinical administration of chloroquine to patients with untreated chronic HIV infection to reduce immune activation
ACTG A5258, we asked whether chloroquine could reduce the immune activation in HIV infection posited to be driven by microbial TLR agonists, such as bacterial elements translocated from the gut and HIV-1 RNAs . We anticipate that blocking this activation pathway might interfere with events in patho...

TranscriptomicsType I IFN responses in rhesus macaques prevent SIV transmission and slow disease progression
In acute HIV infection immune activation may provide target cells and drive virus replication, which innate immunity may limit. Thus, the net effects of inflammatory mediators, including type I interferon (IFN-I), are unclear. Here, we block IFN-I signaling during pathogenic acute SIV infection wit...

TranscriptomicsGene expression profiling of rhesus macaques vaccinated with ALVAC-SIVgpe DNA + SIVgp120 protein subunit and unvaccinated controls after challenge with SIVmac251 - 3 wks post-infection
The SIVmac251 macaque model has been used to evaluate the efficacy of vaccine for HIV. Exposure of macaques to a single high dose of SIVmac251 results in transmission of multiple viral variants, which contrasts the few HIV variants typically transmitted in humans. In here, we investigated whether th...

TranscriptomicsGene expression profiling of rhesus macaques vaccinated with ALVAC-SIVgpe DNA + SIVgp120 protein subunit and unvaccinated controls after challenge with SIVmac251 - 11 wks post-infection
The SIVmac251 macaque model has been used to evaluate the efficacy of vaccine for HIV. Exposure of macaques to a single high dose of SIVmac251 results in transmission of multiple viral variants, which contrasts the few HIV variants typically transmitted in humans. In here, we investigated whether th...
