'Animal models for research on susceptibility to HIV are currently not available. Here we explore whether a macaque model of repeated low-dose rectal or vaginal virus challenges could be employed. We tested the hypothesis that susceptibility to Simian HIV is not merely stochastic in this model but rather is associated ... More

'Cytokines and chemokines are soluble mediators of the immune system that play a crucial role in intercellular signaling, and in the recruitment of cells to inflammation sites. Identification of these molecules in nonhuman primates (NHP) is crucial for the understanding of complex physiological and pathological mechanisms that occur in these ... More
Oligodendrocyte-specific protein is encephalitogenic in rhesus macaques and induces specific demyelination of the optic nerve.

'Oligodendrocyte-specific protein (OSP) is a candidate autoantigen in the development of multiple sclerosis (MS). We evaluated the potential of OSP to induce EAE in rhesus monkeys, an out bred animal model for MS that is immunologically close to humans. Since OSP is a four-membrane spanning protein with highly hydrophobic regions, ... More

'To better define the activity of soluble CXCL16 in the recruitment of polymorphonuclear neutrophils (PMNs) in vivo, utilizing a novel animal model of gout involving engraftment of SCID mice with normal human synovial tissue (ST) injected intragraft with gouty human synovial fluid (SF). For in vitro studies, a modified Boyden ... More
Early rheumatoid arthritis is characterized by a distinct and transient synovial fluid cytokine profile of T cell and stromal cell origin.

'Pathological processes involved in the initiation of rheumatoid synovitis remain unclear. We undertook the present study to identify immune and stromal processes that are present soon after the clinical onset of rheumatoid arthritis (RA) by assessing a panel of T cell, macrophage, and stromal cell related cytokines and chemokines in ...

'Infants of human immunodeficiency virus (HIV)-infected women have high mortality, but the immunologic integrity and protection afforded by the breast milk of HIV-infected women is unknown. We determined morbidity and mortality by 24 months among breast-fed infants of 588 HIV-infected and 137 HIV-uninfected women followed-up in a clinical trial in ... More
Candidate polyanion microbicides inhibit HIV-1 infection and dissemination pathways in human cervical explants.
Heterosexual intercourse remains the major route of HIV-1 transmission worldwide, with almost 5 million new infections occurring each year. Women increasingly bear a disproportionate burden of the pandemic, thus there is an urgent need to develop new strategies to reduce HIV-1 transmission that could be controlled by women themselves. The ... More

PubMed ID21389074
Matrix metalloproteinases (MMPs) and monocyte chemoattractants are key modulators of the biological mechanisms triggered in the periodontium by mechanical forces. The gingival crevicular fluid (GCF) provides a non-invasive method to assess longitudinally the release of inflammatory mediators during orthodontic tooth movement. The goal of this study was to examine the ... More
HIV-1 exposed uninfected men who have sex with men have increased levels of salivary CC-chemokines associated with sexual behavior.
To determine whether soluble molecules with known anti-HIV-1 activity are increased in saliva of HIV-1 exposed uninfected individuals of discordant couples of men who have sex with men (MSM), and whether the levels of these molecules are associated with genetic polymorphisms, sexual behavior and/or HIV-1 neutralizing capacity. Saliva and PBMC ... More
Trypanosoma cruzi (Chagas' disease agent) reduces HIV-1 replication in human placenta.
Several factors determine the risk of HIV mother-to-child transmission (MTCT), such as coinfections in placentas from HIV-1 positive mothers with other pathogens. Chagas' disease is one of the most endemic zoonoses in Latin America, caused by the protozoan Trypanosoma cruzi. The purpose of the study was to determine whether T. ... More

There is a growing interest in the role that cancer biomarkers, metastasis-related molecules, and chemokines may play in the development and progression of various cancers. However, few studies have addressed the reliability of such biomarkers in healthy individuals over time. The objective of this study was to investigate the temporal ... More
