Understanding the pathogenesis of type-I diabetes (T1D) is hindered in humans by the long autoimmune process occurring before clinical onset and by the difficulty to study the pancreas directly. Alternatively, exploring body fluids and particularly peripheral blood can provide some insights. Indeed, circulating cells can function as 'sentinels', with subtle(More)
OBJECTIVE It has been suggested that patients with rheumatoid arthritis (RA) with abundant tumor necrosis factor-alpha (TNF-alpha) are more likely to respond to TNF-alpha inhibitors. We measured expression of TNF-alpha mRNA in peripheral blood of RA patients undergoing infliximab treatment in order to test its predictive value for treatment response. (More)
To study the viral loads of human endogenous retrovirus HERV-K (HML-2) type 1 and type 2 in rheumatoid arthritis (RA), we measured the viral loads of HERV-K (HML-2) type 1 and type 2 using nucleic acid sequence-based amplification (NASBA) technology. We analyzed plasma samples from RA patients (n = 79) and healthy volunteers (HV, n = 46) and synovial fluid(More)
Quantitative real-time RT-PCR is a very powerful technique for measuring gene expression at the mRNA level. In order to compare mRNA expression in different experimental or clinical conditions, expression of a target gene has to be normalized to an appropriate internal standard, which is generally a housekeeping gene. In our study, we have tested several(More)
OBJECTIVE To investigate the genetic contribution of cytokine gene polymorphisms (interleukin 1 (IL1) and tumour necrosis factor alpha (TNFalpha)) on disease phenotype and on response to TNF-blocking agents in a population of patients with juvenile idiopathic arthritis (JIA). METHODS A cohort of 107 consecutive patients with JIA who were receiving(More)
Nucleic acid sequence-based amplification (NASBA) is a sensitive isothermal transcription-based amplification method. We have developed real-time NASBA assays to detect mRNA coding for the estrogen receptor alpha (ESR1) and the progesterone receptor (PGR) in breast tumors by means of duplex reactions using cyclophilin B (PPIB) as the normalizing gene. Both(More)
A dramatic decrease in circulating lymphocyte number is regularly described after septic shock. However, it is unknown how early this alteration develops after diagnosis of shock and if it remains stable over time. Twenty-one septic shock patients with no comorbidities were included within 2 h after the beginning of vasopressive treatment. Flow cytometry(More)
The second phase of septic shock is characterized by an anti-inflammatory state and patients rapidly develop features consistent with immunosuppression. The mechanisms sustaining this disease step are far from being well understood. The objective of the present study was to perform a genome-wide survey of mRNA expression in septic shock patients in order to(More)
BACKGROUND Human peripheral blood is a promising material for biomedical research. However, various kinds of biological and technological factors result in a large degree of variation in blood gene expression profiles. METHODOLOGY/PRINCIPAL FINDINGS Human peripheral blood samples were drawn from healthy volunteers and analysed using the Human Genome(More)
PURPOSE Clinical data suggest that the estrogen receptor (ER) contributes to chemotherapeutic responsiveness. However, ER status alone is not consistently predictive. In this study, we used a microarray approach to find novel ER-related genes that predicted chemotherapy responses, with the hope of providing a robust multi-variable prediction method. (More)
