Mammalian cells contain different phospholipase D enzymes (PLDs) whose distinct physiological roles are poorly understood and whose products have not been characterized. The development of porcine aortic endothelial (PAE) cell lines able to overexpress PLD-1b or -2a under the control of an inducible promoter has enabled us to characterize both the substrate(More)
At least 20 different chromosomal regions have been linked to type 1 diabetes (T1D) susceptibility in humans, using genome screening, candidate gene testing, and studies of human homologues of mouse susceptibility genes. The largest contribution from a single locus (IDDM1) comes from several genes located in the MHC complex on chromosome 6p21.3, accounting(More)
BACKGROUND Muckle-Wells syndrome (MWS), familial cold autoinflammatory syndrome, and neonatal onset multisystem inflammatory disease, also called chronic, infantile, neurological, cutaneous, and articular syndrome, are three hereditary autoinflammatory syndromes caused by mutations affecting the CIAS1/NALP3 gene on chromosome 1q44. The proinflammatory(More)
The pathologies of many infectious, autoimmune and malignant diseases are influenced by the profiles of cytokine production in pro-inflammatory (TH1) and anti-inflammatory (TH2) T cells. Interindividual differences in cytokine profiles appear to be due, at least in part, to allelic polymorphism within regulatory regions of cytokine gene. Many studies have(More)
Vitamin D has important immunomodulatory properties and prevents development of diabetes mellitus in an animal model of insulin-dependent diabetes (IDDM). We have studied the vitamin D receptor locus as a candidate for genetic susceptibility to IDDM in Southern Indian families. We found evidence for an association of one particular vitamin D receptor allele(More)
Within the past few years, the focus on cytokine single nucleotide polymorphism (SNP) function and association with human diseases has increased considerably. This third supplement to the Cytokine Gene Polymorphism in Human Disease: On-line database describes the positive associations of cytokine SNPs in human diseases described in articles published from(More)
The major histocompatibility complex class III tumor necrosis factor-lymphotoxin (TNF-LT) region (6p21.3) was investigated as a possible susceptibility locus for rheumatoid arthritis (RA). Inheritance of five TNF microsatellite markers was determined in 50 multiplex families. Overall, 47 different haplotypes were observed. One of these, the TNF a6, b5, c1,(More)
Many insights have been gained into cytokine-regulated control of inflammatory processes and host defence in recent years. Evidence has also gradually accumulated that cytokine cascades play a central role in events regulating cell death and differentiation. Further developments include an understanding that the biological effects of the tumor necrosis(More)
The autoinflammatory syndromes are systemic disorders characterized by apparently unprovoked inflammation in the absence of high-titer autoantibodies or antigen-specific T lymphocytes. One such illness, TNF-receptor-associated periodic syndrome (TRAPS), presents with prolonged attacks of fever and severe localized inflammation. TRAPS is caused by dominantly(More)
