The emergence of a subset of circulating monocytes during human immunodeficiency virus type 1 (HIV-1) disease has been shown to correlate with cognitive impairment. Thus, it is hypothesized that diagnostic protein profiles may be obtained from these cells from patients with or at risk for HIV-1-associated dementia (HAD). To address this possibility, we used(More)
Human immunodeficiency virus (HIV)-associated cognitive impairment, a significant cause of morbidity, affects up to 30% of HIV-infected people. Its prevalence doubled as patients began to live longer after the introduction of highly active retroviral therapy. Women are now one of the fastest growing groups with acquired immunodeficiency syndrome (AIDS) in(More)
While the mechanisms of cellular aging remain controversial, a leading hypothesis is that mitochondrial oxidative stress and mitochondrial dysfunction play a critical role in this process. Here, we provide data in aging rhesus macaques supporting the hypothesis that increased oxidative stress is a major characteristic of aging and may be responsible for the(More)
Pink-to-red anogenital and facial sexual skin occurs in females of many primate species. Since female sexual skin color varies with reproductive state, it has long been assumed that color acts to stimulate male sexual interest. Although there is supportive evidence for this as regards anogenital skin, it is unclear whether this is also the case for facial(More)
BACKGROUND Pathogenic versus protective outcomes to Dengue virus (DENV) infection are associated with innate immune function. This study aimed to determine the role of increased TLR3- and TLR7/8-mediated innate signaling after Dengue infection of rhesus macaques in vivo to evaluate its impact on disease and anti-DENV immune responses.

Sex workers practicing in high HIV endemic areas have been extensively targeted to test anti-HIV prophylactic strategies. We hypothesize that in women with high levels of genital exposure to semen changes in cervico-vaginal mucosal and/or systemic immune activation will contribute to a decreased susceptibility to HIV-1 infection. To address this question,(More)
Cystatin B is a cysteine protease inhibitor that induces HIV replication in monocyte-derived macrophages (MDM). This protein interacts with signal transducer and activator of transcription (STAT-1) factor and inhibits the interferon (IFN-β) response in Vero cells by preventing STAT-1 translocation to the nucleus. Cystatin B also decreases the levels of(More)
The mucosal expression pattern of interferon-ε in rhesus macaques" (2014). Qingsheng Li Publications. Paper 18. ABSTRACT Type I IFNs play an important role in innate and adap-tive immunity against viral infections. A novel type I IFN, namely IFN-␧, which can protect against vaginal transmission of HSV2 and Chlamydia muridarum bacterial infection, has been(More)
Type I IFNs play an important role in innate and adaptive immunity against viral infections. A novel type I IFN, namely IFN-ε, which can protect against vaginal transmission of HSV2 and Chlamydia muridarum bacterial infection, has been described in mice and humans. Nevertheless, the principle cell type and the expression pattern of IFN-ε in tissues remain(More)
In Puerto Rico, risk for transmission of B-virus from free-ranging rhesus monkeys to humans has become a serious challenge. An incident with an injured rhesus monkey, seropositive for B-virus, resulted in inappropriate administration of antiviral postexposure prophylaxis. This incident underscores the importance of education about risks associated with(More)
