Dysregulation of the antiviral immune response may contribute to autoimmune diseases. Here, we hypothesized that altered expression or function of MAVS, a key molecule downstream of the viral sensors RIG-I and MDA-5, may impair antiviral cell signalling and thereby influence the risk for systemic lupus erythematosus (SLE), the prototype autoimmune disease.(More)
BACKGROUND RIG-I is a pivotal receptor that detects numerous RNA and DNA viruses. Thus, its defectiveness may strongly impair the host antiviral immunity. Remarkably, very little information is available on RIG-I single-nucleotide polymorphisms (SNPs) presenting a functional impact on the host response. METHODOLOGY/PRINCIPAL FINDINGS Here, we studied all(More)
In Drosophila, the RING finger protein d-Goliath was originally identified as a transcription factor involved in the embryo mesoderm formation [Bouchard, M.L., Cote, S., 1993. The Drosophila melanogaster developmental gene g1 encodes a variant zinc-finger-motif protein. Gene 125, 205-209]. In mouse, the m-Goliath mRNA level was shown to be increased in(More)
By systematic analysis of a human testis library, we have isolated the hH-Rev107-3 cDNA, identical to hH-Rev107-1 cDNA, which was previously described as a class II tumor suppressor gene. In this study, two transcripts (1 and 0.8 kb) were detected by Northern blot in all human tissues, excepted in thymus. The strongest expression was found in testis,(More)
The localization of two enkephalin-hydrolysing aminopeptidases i.e. aminopeptidase M (aminopeptidase N, EC relatively insensitive to puromycin (Ki = 78 microM), and a puromycin-sensitive aminopeptidase (Ki = 1 microM) was studied in rat brain. The two aminopeptidases were differentially identified and/or localized using polyclonal(More)
Trappin-2/Elafin is a potent serine protease inhibitor which prevents excessive damage under inflammatory status. This "alarm-antiprotease" is locally expressed by epithelial cells and immune cells such as macrophages and γδ T cells. It has also been proven to modulate a wide range of parameters that are critical for the inflammation process like modulating(More)
According to the WHO, and despite reduction in mortality rates, there were an estimated 438 000 malaria deaths in 2015. Therefore new antimalarials capable of limiting organ damage are still required. We show that systemic and lung adenovirus (Ad)-mediated over-expression of trappin-2 (T-2) an antibacterial molecule with anti-inflammatory activity,(More)
We have cloned the rat homologue of the ring-H2 protein Goliath involved in Drosophila development. The rat Goliath mRNA (1.85 kb) was translated as a major ubiquitous protein species of 28-kDa and three larger isoforms (50, 46, and 36 kDa) expressed mainly in liver, lung, stomach, heart, and thymus and barely detectable in other tissues (kidney, skeletal(More)
Mechanisms underlying the pathophysiology of minimal change nephrotic syndrome (MCNS), the most frequent of glomerular diseases in children, remain elusive, although recent arguments suggest that T cell dysfunction may be involved in the pathogenesis of this disease. Recently, we reported that activated T cells of these patients display a down-regulation of(More)
A predominantly microvascular localization of aminopeptidase M (APM) was established both by immunohistochemistry and biochemical studies of isolated microvessels. In addition a high relative specific activity of APM was evidenced in fractions enriched in synaptic membranes.
