'The IG20 gene encodes at least four splice variants, including DENN-SV and IG20. DENN-SV is constitutively expressed at higher levels in tumor tissues. Cells transfected with the DENN-SV cDNA show increased resistance to tumor necrosis factor alpha (TNFalpha), TNF-related apoptosis-inducing ligand (TRAIL), etoposide, and vinblastine treatment, whereas overexpression of IG20 ...

'ABSTRACT: BACKGROUND: Persistent symptoms after treatment of neuroborreliosis (NB) are well-documented, although the causative mechanisms are mainly unknown. The effect of repeated antibiotic treatment has not been studied in detail. The aim of this study was to determine whether: (1) persistent symptoms improve with doxycycline treatment; (2) doxycycline has an ... More
Analysis of SF and plasma cytokines provides insights into the mechanisms of inflammatory arthritis and may predict response to therapy.
'Biologic drugs have revolutionized the care of RA, but are expensive and not universally effective. To further understand the inflammatory mechanisms underlying RA and identify potential biomarkers predicting response to therapy, we measured multiple cytokine concentrations in SF of patients with inflammatory arthritides (IAs) and, in a subset of patients ...

Expression of ICOS on human melanoma-infiltrating CD4+CD25highFoxp3+ T regulatory cells: implications and impact on tumor-mediated immune suppression.
'Interaction of ICOS with its ligand (ICOSL, B7-H2) promotes T cell responses. As CD4+CD25highFoxp3+ naturally occurring T regulatory cells in melanoma patients express ICOS, we investigated the impact of ICOS on naturally occurring T regulatory cell function.' ... 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
Quantitative validation and comparison of multiplex cytokine kits.
'The focus of biomarker studies is shifting toward deciphering patterns of biomolecules as they provide a more comprehensive depiction of disease than individual biomarkers. Multiplexing technologies are crucial in deciphering such patterns, but it is essential that they are validated for reproducibility and precision to ensure accurate protein identification. Here ...

JournalClin Cancer Res
PubMed ID17545521
Cytokines and growth factors modulated by transcription factor nuclear factor-kappaB and secreted by tumor and stromal cells are detectable in serum of patients with advanced cancers, including head and neck squamous cell carcinomas (SCC). Longitudinal changes in these serum factors could be early biomarkers of treatment response and survival. ... More

In most studies, circulating biomarkers are usually assessed from a single sample, assuming that this single measurement represents the long-term biomarker status of the individual. Such an assumption is rarely tested although it may not be valid for all biomarkers. The objective of this study was to investigate the temporal ... 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

Preterm birth (PTB) is hypothesized to be an inflammatory response disease. However, no single factor alone is likely to explain PTB risk. It is more probable that coordinated networks of cytokines affect risk. Therefore, we examined the relationships between amniotic fluid (AF) cytokines/chemokines and related biomarkers in PTB and normal ... More

JournalFEMS Immunol Med Microbiol
PubMed ID14987733
Differentiation of hematopoietic stem cells (HSCs) can be influenced by different stimuli, including cytotoxic agents, certain cytokines, and contact with pathogens. Infection may result in dysregulation of these important progenitor cells and therefore interfere with the availability of blood cells. In this study we analyzed the effect of bacterial infection ...

Human skin in organ culture and human skin cells (keratinocytes and fibroblasts) in monolayer culture for assessment of chemically induced skin damage.
Human skin cells (epidermal keratinocytes and dermal fibroblasts) in monolayer culture and human skin in organ culture were exposed to agents that are known to produce irritation (redness, dryness, edema and scaly crusts) when applied topically to skin. Among the agents used were three well accepted contact irritants (i.e., all-trans ... More

Dendritic cells (DCs) are bone marrow-derived mononuclear cells that play a central role in the initiation of immune responses. Because human lung DCs have been incompletely characterized, we enumerated and phenotyped mononuclear cell populations from excess lung tissue obtained at surgery. Myeloid DCs (MDCs) were identified as CD1c(+)CD11c(+)CD14(-)HLA-DR(+) cells and ... More
